Introduction The San Joaquin River (SJR) supports one of the most productive agricultural regions in the world and its productivity is heavily dependant on irrigated agriculture. A consequence of irrigated agriculture is the production of return flows conveyed down gradient drains that eventually discharge to surface waters. Agricultural drainage may have significant nutrient load and can impact algae growth and general water quality in the SJR. Individual farmers and agricultural organizations, such as drainage authorities, are in need of tools to manage the environmental impacts of agricultural activities (Stringfellow, 2008).
For the years 2005 through 2007, sites throughout the San Joaquin Valley watershed were sampled to assess the overall water quality in the region. One thousand nine hundred and ninety-six (1996) individual surface water samples were collected and analyzed and WQ was assessed at 113 locations in the SJR basin (Borglin et al., 2008). Samples were processed and analyzed by the Environmental Engineering Research Program (EERP) laboratory at the University of the Pacific as well as at the University of California, Davis, Dahlgren Lab. This report includes temporal graphs of total phosphorus (Tot-P) data analyzed by the UCD Dahlgren laboratory from 2005-2007.
MethodsDepth integrated field samples were colleted during 2005-2007 in the upper San Joaquin River in accordance with EERP Field Standard Operating Procedures Protocol Book (Graham 2008). Water samples were colleted in glass 1000 mL bottles (Wheaton Science Products, Millville, NJ), 1000 mL HDPE Trace-Clean narrow mouth plastic bottles (VWR International), 250 mL HDPE Trace-Clean wide mouth plastic bottles (VWR International) as well as 40 mL trace clean vials with PTFE septa (IChem, Rockwood, TN). Bottles were labeled with the appropriate sample number, site name and sampling date. All bottles were rinsed with sample water prior to sample collection. Some sites required a bucket to collect sample water because of accessibility from a high bridge or platform. For these sites, the bucket was pre-rinsed with sample water and sample bottles were filled using a rinsed funnel. Care was taken to distribute water simultaneously to all sample bottles (rather than sequentially). Samples were immediately stored at 4°C after sampling (cooler temperature was recorded in the lab upon delivery) and transported to the EERP lab on the day of sampling.
Within 24 hours of collection samples were transported from the EERP laboratory to the UCD laboratory were they were stored at -20°C until the analysis could be completed.
Tot-P was analyzed on unfiltered samples using the stannous chloride method after digestion using the SM 4500-P.D (APHA,2005). To digest, 5.0 mL of each sample was aliquotted into trace clean, 5.0 mL digestion reagent was added (10 g potassium persulfate, 6 g boric acid, and 3 g NaOH in 1000mL Millipore water) was added and then was autoclaved for 1 hour. After cooling, Tot-P was determined using the stannous chloride method.

Results/DiscussionWith each set of Tot-P field samples analyzed in the UCD laboratory, quality assurance samples including a a field duplicate, a trip blank, and lab blanks were also analyzed. Between 2005 and 2007, 95.0% of all quality assurance samples were within a passing range (Borglin et al, 2008). Proficiency check samples, standards with unknown concentration to the laboratory analyst, were run approximately twice a year. Four proficiency check samples were analyzed for Tot-P in the UCD laboratory during 2005-2007, and all of these samples were found to be within the acceptable range. Samples were measured ranging from 0.01-6.34 mg/L Tot-P. The average concentration of Tot-P in water samples collected was 0.33 mg/L Tot-P. Tot-P was also analyzed by the EERP laboratory on all of the same water samples starting in late 2006 and has a high correlation to values measured by EERP. When all data points measured by the two labs are compared they have r2=0.951, and both labs have similar recovery rates. EERP measured 89.1% of Tot-P as UCD (Figure 2).
These temporal plots (Figures 3-104) as well as plotting EERP data against UCD’s data (Figure 2) created an easy visual way to find outliers and double check data entry for possible mistakes.

Introduction The San Joaquin River (SJR) supports one of the most productive agricultural regions in the world and its productivity is heavily dependant on irrigated agriculture. A consequence of irrigated agriculture is the production of return flows conveyed down gradient drains that eventually discharge to surface waters. Agricultural drainage may have significant nutrient load and can impact algae growth and general water quality in the SJR. Individual farmers and agricultural organizations, such as drainage authorities, are in need of tools to manage the environmental impacts of agricultural activities (Stringfellow, 2008).
For the years 2005 through 2007, sites throughout the San Joaquin Valley watershed were sampled to assess the overall water quality in the region. One thousand nine hundred and ninety-six (1996) individual surface water samples were collected and analyzed and WQ was assessed at 113 locations in the SJR basin (Borglin et al., 2008). Samples were processed and analyzed by the Environmental Engineering Research Program (EERP) laboratory at the University of the Pacific as well as at the University of California, Davis, Dahlgren Lab. This report includes temporal graphs of total nitrogen (Tot-N) data analyzed by the UCD Dahlgren laboratory from 2005-2007.
MethodsDepth integrated field samples were colleted during 2005-2007 in the upper San Joaquin River in accordance with EERP Field Standard Operating Procedures Protocol Book (Graham 2008). Water samples were colleted in glass 1000 mL bottles (Wheaton Science Products, Millville, NJ), 1000 mL HDPE Trace-Clean narrow mouth plastic bottles (VWR International), 250 mL HDPE Trace-Clean wide mouth plastic bottles (VWR International) as well as 40 mL trace clean vials with PTFE septa (IChem, Rockwood, TN). Bottles were labeled with the appropriate sample number, site name and sampling date. All bottles were rinsed with sample water prior to sample collection. Some sites required a bucket to collect sample water because of accessibility from a high bridge or platform. For these sites, the bucket was pre-rinsed with sample water and sample bottles were filled using a rinsed funnel. Care was taken to distribute water simultaneously to all sample bottles (rather than sequentially). Samples were immediately stored at 4°C after sampling (cooler temperature was recorded in the lab upon delivery) and transported to the EERP lab on the day of sampling.
Within 24 hours of collection samples were transported from the EERP laboratory to the UCD laboratory where they were stored at -20oC until Tot-N analysis could be completed.
Tot-N was determined using an automated membrane diffusion/conductivity detection method (Carlson, 1978, 1986; Carlson et al., 1990) from unfiltered sample following persulfate oxidation (Yu et al., 1994) using a 1% persulfate oxidant concentration, a sample:oxidant ratio of 1:1 (V/V), and heating in an autoclave. The limit of detection for this method was 50 ppb N.

Results/DiscussionWith each set of Tot-N field samples analyzed in the UCD laboratory, quality assurance samples including a field duplicate, a trip blank, and lab blanks were also analyzed. 96.17% of all quality assurance samples were within a passing range (Spier et al, 2008). Proficiency check samples, standards with unknown concentration to the laboratory analyst, were run approximately twice a year. Twelve proficiency check samples were analyzed for Tot-N in the EERP laboratory during 2007, and nine of these samples were found to be within the acceptable range. Samples were measured ranging from 0.02-40.06 mg/L Tot-N. The average concentration of Tot-N found in samples collected was 4.39 mg/L Tot-N. Tot-N was also analyzed by the EERP laboratory on the same water samples starting in the summer of 2007and has a high correlation to values measured by EERP. When all data points measured by the two labs are compared they have r2=0.9896(Spier et al, 2008). Tot-N samples measured by EERP have about 101% as much Tot-N as the same samples measured by UCD (Figure 2).

Introduction The San Joaquin River (SJR) supports one of the most productive agricultural regions in the world and its productivity is heavily dependant on irrigated agriculture. A consequence of irrigated agriculture is the production of return flows conveyed down gradient drains that eventually discharge to surface waters. Agricultural drainage may have significant nutrient load and can impact algae growth and general water quality in the SJR. Individual farmers and agricultural organizations, such as drainage authorities, are in need of tools to manage the environmental impacts of agricultural activities (Stringfellow, 2008).
For the years 2005 through 2007, sites throughout the San Joaquin Valley watershed were sampled to assess the overall water quality in the region. One thousand nine hundred and ninety-six (1996) individual surface water samples were collected and analyzed and WQ was assessed at 113 locations in the SJR basin (Borglin et al., 2008). Samples were processed and analyzed by the Environmental Engineering Research Program (EERP) laboratory at the University of the Pacific as well as at the University of California, Davis, Dahlgren Lab. This report includes temporal graphs of sulfate (SO4) data analyzed by the UCD Dahlgren laboratory between 2005 and 2007.
MethodsDepth integrated field samples were colleted during 2005-2007 in the upper San Joaquin River in accordance with EERP Field Standard Operating Procedures Protocol Book (Graham 2008). Water samples were colleted in glass 1000 mL bottles (Wheaton Science Products, Millville, NJ), 1000 mL HDPE Trace-Clean narrow mouth plastic bottles (VWR International), 250 mL HDPE Trace-Clean wide mouth plastic bottles (VWR International) as well as 40 mL trace clean vials with PTFE septa (IChem, Rockwood, TN). Bottles were labeled with the appropriate sample number, site name and sampling date. All bottles were rinsed with sample water prior to sample collection. Some sites required a bucket to collect sample water because of accessibility from a high bridge or platform. For these sites, the bucket was pre-rinsed with sample water and sample bottles were filled using a rinsed funnel. Care was taken to distribute water simultaneously to all sample bottles (rather than sequentially). Samples were immediately stored at 4°C after sampling (cooler temperature was recorded in the lab upon delivery) and transported to the EERP lab on the day of sampling.
Within 24 hours of collection samples were transported from the EERP laboratory to the UCD laboratory for analysis, during this time period samples were stored in coolers at 4°C.
Ion chromatography was utilized for measuring SO42- using a Dionex ICS-2000 Ion
Chromatograph (Dionex Corporation, Sunnyvale, CA) (SM-4110 B). The reportable limit for this method is 0.02 mg/L SO4
2- .

Results/DiscussionSamples were measured ranging from 0.0-2108 mg/L SO4. The average concentration of SO4 in water samples collected was 213.9 mg/L SO4. These temporal plots (Figures 3-104) created an easy visual way to find outliers and double check data entry for possible mistakes.

Introduction The San Joaquin River (SJR) supports one of the most productive agricultural regions in the world and its productivity is heavily dependant on irrigated agriculture. A consequence of irrigated agriculture is the production of return flows conveyed down gradient drains that eventually discharge to surface waters. Agricultural drainage may have significant nutrient load and can impact algae growth and general water quality in the SJR. Individual farmers and agricultural organizations, such as drainage authorities, are in need of tools to manage the environmental impacts of agricultural activities (Stringfellow, 2008).
For the years 2005 through 2007, sites throughout the San Joaquin Valley watershed were sampled to assess the overall water quality in the region. One thousand nine hundred and ninety-six (1996) individual surface water samples were collected and analyzed and WQ was assessed at 113 locations in the SJR basin (Borglin et al., 2008). Samples were processed and analyzed by the Environmental Engineering Research Program (EERP) laboratory at the University of the Pacific as well as at the University of California, Davis, Dahlgren Lab. This report includes temporal graphs of sodium (Na) data analyzed by the UCD Dahlgren laboratory between 2005 and 2007.
MethodsDepth integrated field samples were colleted during 2005-2007 in the upper San Joaquin River in accordance with EERP Field Standard Operating Procedures Protocol Book (Graham 2008). Water samples were colleted in glass 1000 mL bottles (Wheaton Science Products, Millville, NJ), 1000 mL HDPE Trace-Clean narrow mouth plastic bottles (VWR International), 250 mL HDPE Trace-Clean wide mouth plastic bottles (VWR International) as well as 40 mL trace clean vials with PTFE septa (IChem, Rockwood, TN). Bottles were labeled with the appropriate sample number, site name and sampling date. All bottles were rinsed with sample water prior to sample collection. Some sites required a bucket to collect sample water because of accessibility from a high bridge or platform. For these sites, the bucket was pre-rinsed with sample water and sample bottles were filled using a rinsed funnel. Care was taken to distribute water simultaneously to all sample bottles (rather than sequentially). Samples were immediately stored at 4°C after sampling (cooler temperature was recorded in the lab upon delivery) and transported to the EERP lab on the day of sampling.
Within 24 hours of collection samples were transported from the EERP laboratory to the UCD laboratory for analysis, during this time period samples were stored in coolers at 4°C.
Ion chromatography was utilized for measuring Na+ using a Dionex ICS-2000 Ion Chromatograph (Dionex Corporation, Sunnyvale, CA) (ASTM D6919-03). The reportable limit for this method is 0.05 mg/L Na+ .

Results/DiscussionSamples were measured ranging from 0.0-1043 mg/L Na. The average concentration of Na in water samples collected was 159.31 mg/L Na. These temporal plots (Figures 3-104) created an easy visual way to find outliers and double check data entry for possible mistakes.

Introduction The San Joaquin River (SJR) supports one of the most productive agricultural regions in the world and its productivity is heavily dependant on irrigated agriculture. A consequence of irrigated agriculture is the production of return flows conveyed down gradient drains that eventually discharge to surface waters. Agricultural drainage may have significant nutrient load and can impact algae growth and general water quality in the SJR. Individual farmers and agricultural organizations, such as drainage authorities, are in need of tools to manage the environmental impacts of agricultural activities (Stringfellow, 2008).
For the years 2005 through 2007, sites throughout the San Joaquin Valley watershed were sampled to assess the overall water quality in the region. One thousand nine hundred and ninety-six (1996) individual surface water samples were collected and analyzed and WQ was assessed at 113 locations in the SJR basin (Borglin et al., 2008). Samples were processed and analyzed by the Environmental Engineering Research Program (EERP) laboratory at the University of the Pacific as well as at the University of California, Davis, Dahlgren Lab. This report includes temporal graphs of potassium (K) data analyzed by the UCD Dahlgren laboratory between 2005 and 2007.
MethodsDepth integrated field samples were colleted during 2005-2007 in the upper San Joaquin River in accordance with EERP Field Standard Operating Procedures Protocol Book (Graham 2008). Water samples were colleted in glass 1000 mL bottles (Wheaton Science Products, Millville, NJ), 1000 mL HDPE Trace-Clean narrow mouth plastic bottles (VWR International), 250 mL HDPE Trace-Clean wide mouth plastic bottles (VWR International) as well as 40 mL trace clean vials with PTFE septa (IChem, Rockwood, TN). Bottles were labeled with the appropriate sample number, site name and sampling date. All bottles were rinsed with sample water prior to sample collection. Some sites required a bucket to collect sample water because of accessibility from a high bridge or platform. For these sites, the bucket was pre-rinsed with sample water and sample bottles were filled using a rinsed funnel. Care was taken to distribute water simultaneously to all sample bottles (rather than sequentially). Samples were immediately stored at 4°C after sampling (cooler temperature was recorded in the lab upon delivery) and transported to the EERP lab on the day of sampling.
Within 24 hours of collection samples were transported from the EERP laboratory to the UCD laboratory for analysis, during this time period samples were stored in coolers at 4°C.
Ion chromatography was utilized for measuring K+ using a Dionex ICS-2000 Ion Chromatograph (Dionex Corporation, Sunnyvale, CA) (ASTM D6919-03). The reportable limit for this method is 0.05 mg/L K2+ .

Results/DiscussionSamples were measured ranging from 0.0-54.7 mg/L K. The average concentration of K in water samples collected was 5.24 mg/L K. These temporal plots (Figures 3-104) created an easy visual way to find outliers and double check data entry for possible mistakes.

Introduction The San Joaquin River (SJR) supports one of the most productive agricultural regions in the world and its productivity is heavily dependant on irrigated agriculture. A consequence of irrigated agriculture is the production of return flows conveyed down gradient drains that eventually discharge to surface waters. Agricultural drainage may have significant nutrient load and can impact algae growth and general water quality in the SJR. Individual farmers and agricultural organizations, such as drainage authorities, are in need of tools to manage the environmental impacts of agricultural activities (Stringfellow, 2008).
For the years 2005 through 2007, sites throughout the San Joaquin Valley watershed were sampled to assess the overall water quality in the region. One thousand nine hundred and ninety-six (1996) individual surface water samples were collected and analyzed and WQ was assessed at 113 locations in the SJR basin (Borglin et al., 2008). Samples were processed and analyzed by the Environmental Engineering Research Program (EERP) laboratory at the University of the Pacific as well as at the University of California, Davis, Dahlgren Lab. This report includes temporal graphs of dissolved nitrate (NO3-N)data analyzed by the UCD Dahlgren laboratory from 2005-2007.
MethodsDepth integrated field samples were colleted during 2005-2007 in the upper San Joaquin River in accordance with EERP Field Standard Operating Procedures Protocol Book (Graham 2008). Water samples were colleted in glass 1000 mL bottles (Wheaton Science Products, Millville, NJ), 1000 mL HDPE Trace-Clean narrow mouth plastic bottles (VWR International), 250 mL HDPE Trace-Clean wide mouth plastic bottles (VWR International) as well as 40 mL trace clean vials with PTFE septa (IChem, Rockwood, TN). Bottles were labeled with the appropriate sample number, site name and sampling date. All bottles were rinsed with sample water prior to sample collection. Some sites required a bucket to collect sample water because of accessibility from a high bridge or platform. For these sites, the bucket was pre-rinsed with sample water and sample bottles were filled using a rinsed funnel. Care was taken to distribute water simultaneously to all sample bottles (rather than sequentially). Samples were immediately stored at 4°C after sampling (cooler temperature was recorded in the lab upon delivery) and transported to the EERP lab on the day of sampling.
Within 24 hours of collection samples for NO3-N and ammonia (Soluble NO3-N and Soluble NH3-N ) were transported from the EERP laboratory to the UCD laboratory where they were filtered through a pre-rinsed, 0.22 µm polycarbonate membrane (Millipore IsoporeTM), and then stored at -20oC until NO3-N analysis could be completed.
NO3-N and Soluble NH3-N were quantified simultaneously using an automated membrane diffusion/conductivity detection method (Carlson, 1978, 1986; Carlson et al., 1990). The limit of detection for this method was 50 ppb N.

With each set of NO3-N field samples analyzed in the UCD laboratory, quality assurance samples including a field duplicate, a trip blank, and lab blanks were also analyzed. 100% of all quality assurance samples were within a passing range (Borglin et al, 2008). Proficiency check samples, standards with unknown concentration to the laboratory analyst, were run approximately twice a year. Five proficiency check samples were analyzed for NO3-N in the EERP laboratory during 2007, and all of these samples were found to be within the acceptable range. Samples were measured ranging from 0.0-36.4 mg/L NO3-N. The average concentration of NO3-N in water samples collected was 3.55 mg/L NO3-N. NO3-N was also analyzed by the EERP laboratory on the same water samples starting in the summer of 2007, and has a high correlation to values measured by EERP. When all data points measured by the two labs are compared they have r2=0.983(Spier et al, 2008). NO3-N samples measured by EERP have about 89.3% as much NO3-N as the same samples measured by UCD (Figure 2).

Introduction The San Joaquin River (SJR) supports one of the most productive agricultural regions in the world and its productivity is heavily dependant on irrigated agriculture. A consequence of irrigated agriculture is the production of return flows conveyed down gradient drains that eventually discharge to surface waters. Agricultural drainage may have significant nutrient load and can impact algae growth and general water quality in the SJR. Individual farmers and agricultural organizations, such as drainage authorities, are in need of tools to manage the environmental impacts of agricultural activities (Stringfellow, 2008).
For the years 2005 through 2007, sites throughout the San Joaquin Valley watershed were sampled to assess the overall water quality in the region. One thousand nine hundred and ninety-six (1996) individual surface water samples were collected and analyzed and WQ was assessed at 113 locations in the SJR basin (Borglin et al., 2008). Samples were processed and analyzed by the Environmental Engineering Research Program (EERP) laboratory at the University of the Pacific as well as at the University of California, Davis, Dahlgren Lab. This report includes temporal graphs of magnesium (Mg) data analyzed by the UCD Dahlgren laboratory between 2005 and 2007.
MethodsDepth integrated field samples were colleted during 2005-2007 in the upper San Joaquin River in accordance with EERP Field Standard Operating Procedures Protocol Book (Graham 2008). Water samples were colleted in glass 1000 mL bottles (Wheaton Science Products, Millville, NJ), 1000 mL HDPE Trace-Clean narrow mouth plastic bottles (VWR International), 250 mL HDPE Trace-Clean wide mouth plastic bottles (VWR International) as well as 40 mL trace clean vials with PTFE septa (IChem, Rockwood, TN). Bottles were labeled with the appropriate sample number, site name and sampling date. All bottles were rinsed with sample water prior to sample collection. Some sites required a bucket to collect sample water because of accessibility from a high bridge or platform. For these sites, the bucket was pre-rinsed with sample water and sample bottles were filled using a rinsed funnel. Care was taken to distribute water simultaneously to all sample bottles (rather than sequentially). Samples were immediately stored at 4°C after sampling (cooler temperature was recorded in the lab upon delivery) and transported to the EERP lab on the day of sampling.
Within 24 hours of collection samples were transported from the EERP laboratory to the UCD laboratory for analysis, during this time period samples were stored in coolers at 4°C.
Ion chromatography was utilized for measuring Mg2+ using a Dionex ICS-2000 Ion Chromatograph (Dionex Corporation, Sunnyvale, CA) (ASTM D6919-03). The reportable limit for this method is 0.08 mg/L Mg2+ .

Results/DiscussionSamples were measured ranging from 0.0-957.3 mg/L Mg. The average concentration of Mg in samples collected was 29.7 mg/L Mg. These temporal plots (Figures 3-104) created an easy visual way to find outliers and double check data entry for possible mistakes.

Introduction The San Joaquin River (SJR) supports one of the most productive agricultural regions in the world and its productivity is heavily dependant on irrigated agriculture. A consequence of irrigated agriculture is the production of return flows conveyed down gradient drains that eventually discharge to surface waters. Agricultural drainage may have significant nutrient load and can impact algae growth and general water quality in the SJR. Individual farmers and agricultural organizations, such as drainage authorities, are in need of tools to manage the environmental impacts of agricultural activities (Stringfellow, 2008).
For the years 2005 through 2007, sites throughout the San Joaquin Valley watershed were sampled to assess the overall water quality in the region. One thousand nine hundred and ninety-six (1996) individual surface water samples were collected and analyzed and WQ was assessed at 113 locations in the SJR basin (Borglin et al., 2008). Samples were processed and analyzed by the Environmental Engineering Research Program (EERP) laboratory at the University of the Pacific as well as at the University of California, Davis, Dahlgren Lab. This report presents temporal plots of dissolved ortho-phosphate-phosphorus (PO4-P) for data analyzed by the UCD Dahlgren laboratory between 2005 and 2007.
MethodsDepth integrated field samples were colleted during 2005-2007 in the upper San Joaquin River in accordance with EERP Field Standard Operating Procedures Protocol Book (Graham 2008). Water samples were colleted in glass 1000 mL bottles (Wheaton Science Products, Millville, NJ), 1000 mL HDPE Trace-Clean narrow mouth plastic bottles (VWR International), 250 mL HDPE Trace-Clean wide mouth plastic bottles (VWR International) as well as 40 mL trace clean vials with PTFE septa (IChem, Rockwood, TN). Bottles were labeled with the appropriate sample number, site name and sampling date. All bottles were rinsed with sample water prior to sample collection. Some sites required a bucket to collect sample water because of accessibility from a high bridge or platform. For these sites, the bucket was pre-rinsed with sample water and sample bottles were filled using a rinsed funnel. Care was taken to distribute water simultaneously to all sample bottles (rather than sequentially). Samples were immediately stored at 4°C after sampling (cooler temperature was recorded in the lab upon delivery) and transported to the EERP lab on the day of sampling.
Within 24 hours of collection samples for PO4-P were transported from the EERP laboratory to the UCD laboraroty where they were filtered through a pre-rinsed, 0.22 µm polycarbonate membrane (Millipore IsoporeTM), and then stored at -20oC until ammonia analysis could be completed.
PO4-P was determined on the filtrate using the stannous chloride method. SM 4500-P.D (APHA,2005). The limit of detection for this method is approximately 3 ppb PO4-P in clean water using a 1 cm cell for measurement.

Results/DiscussionWith each set of PO4-P field samples analyzed in the UCD laboratory, quality assurance samples including a field duplicate, a trip blank, and lab blanks were also analyzed. Between 2005 and 2007, 93.5% of all quality assurance samples were within a passing range (Borglin et al, 2008). Proficiency check samples, standards with unknown concentration to the laboratory analyst, were run approximately twice a year. Four out of five proficiency check samples analyzed for PO4-P in the UCD laboratory during 2006 and 2007 were found to be within the acceptable range. Samples were measured ranging from 0.0-5.31 mg/L PO4-P. The average concentration of PO4-P in samples collected was 0.21 mg/L PO4-P. PO4-P was also analyzed by the EERP laboratory on all of the same water samples, and has a high correlation to values measured by UCD. When all data points measured by the two labs are compared they have r2=0.849, and both labs have almost the same recovery rate, EERP measured 99.94% of PO4-P as UCD (Figure 2). In general PO4-P was lowest during the summer months and peaks were found most often during the wet season.

Introduction The San Joaquin River (SJR) supports one of the most productive agricultural regions in the world and its productivity is heavily dependant on irrigated agriculture. A consequence of irrigated agriculture is the production of return flows conveyed down gradient drains that eventually discharge to surface waters. Agricultural drainage may have significant nutrient load and can impact algae growth and general water quality in the SJR. Individual farmers and agricultural organizations, such as drainage authorities, are in need of tools to manage the environmental impacts of agricultural activities (Stringfellow, 2008).
For the years 2005 through 2007, sites throughout the San Joaquin Valley watershed were sampled to assess the overall water quality in the region. One thousand nine hundred and ninety-six (1996) individual surface water samples were collected and analyzed and WQ was assessed at 113 locations in the SJR basin (Borglin et al., 2008). Samples were processed and analyzed by the Environmental Engineering Research Program (EERP) laboratory at the University of the Pacific as well as at the University of California, Davis, Dahlgren Lab. This report presents temporal plots of dissolved ammonia-nitrogen (NH3-N) for data analyzed by the UCD Dahlgren laboratory between 2005-2007.
MethodsDepth integrated field samples were colleted during 2005-2007 in the upper San Joaquin River in accordance with EERP Field Standard Operating Procedures Protocol Book (Graham 2008). Water samples were colleted in glass 1000 mL bottles (Wheaton Science Products, Millville, NJ), 1000 mL HDPE Trace-Clean narrow mouth plastic bottles (VWR International), 250 mL HDPE Trace-Clean wide mouth plastic bottles (VWR International) as well as 40 mL trace clean vials with PTFE septa (IChem, Rockwood, TN). Bottles were labeled with the appropriate sample number, site name and sampling date. All bottles were rinsed with sample water prior to sample collection. Some sites required a bucket to collect sample water because of accessibility from a high bridge or platform. For these sites, the bucket was pre-rinsed with sample water and sample bottles were filled using a rinsed funnel. Care was taken to distribute water simultaneously to all sample bottles (rather than sequentially). Samples were immediately stored at 4°C after sampling (cooler temperature was recorded in the lab upon delivery) and transported to the EERP lab on the day of sampling.
Within 24 hours of collection samples for NO3-N and NH3-N were transported from the EERP laboratory to the UCD laboratory, where they were filtered through a pre-rinsed, 0.22 µm polycarbonate membrane (Millipore IsoporeTM), and then stored at -20oC until NH3-N analysis could be completed.
NO3-N and Soluble NH3-N were quantified simultaneously using an automated membrane diffusion/conductivity detection method (Carlson, 1978, 1986; Carlson et al., 1990). The limit of detection for this method was 50 ppb N.

Results/DiscussionWith each set of NH3-N field samples analyzed in the UCD laboratory, quality assurance samples including a field duplicate, a trip blank, and lab blanks were also analyzed. 95.02% of all quality assurance samples were within a passing range (Borglin et al, 2008). Proficiency check samples, standards with unknown concentration to the laboratory analyst, were run approximately twice a year. Four proficiency check samples were analyzed for NH3-N in the UCD laboratory during 2005-2007, and all of these samples were found to be within the acceptable range. Samples were measured ranging from 0.0-21.76 mg/L NH3-N. The average concentration of NH3-N in samples collected was 0.17 mg/L NH3-N. NH3-N was also analyzed at EERP starting in the summer of 2007, on the same water samples and has a high correlation to values measured by EERP. When all data points measured by the two labs are compared they have r2=0.956 (Spier et al, 2008). NH3-N samples measured by EERP have about 91.1% as much NH3-N as the same samples measured by UCD (Figure 2). NH3-N was had low concentrations for most of the year with spikes appearing in the summer months for several sites.

Introduction The San Joaquin River (SJR) supports one of the most productive agricultural regions in the world and its productivity is heavily dependant on irrigated agriculture. A consequence of irrigated agriculture is the production of return flows conveyed down gradient drains that eventually discharge to surface waters. Agricultural drainage may have significant nutrient load and can impact algae growth and general water quality in the SJR. Individual farmers and agricultural organizations, such as drainage authorities, are in need of tools to manage the environmental impacts of agricultural activities (Stringfellow, 2008).
For the years 2005 through 2007, sites throughout the San Joaquin Valley watershed were sampled to assess the overall water quality in the region. One thousand nine hundred and ninety-six (1996) individual surface water samples were collected and analyzed and WQ was assessed at 113 locations in the SJR basin (Borglin et al., 2008). Samples were processed and analyzed by the Environmental Engineering Research Program (EERP) laboratory at the University of the Pacific as well as at the University of California, Davis, Dahlgren Lab. This report includes temporal graphs of chlorine (Cl) data analyzed by the UCD Dahlgren laboratory between 2005 and 2007.
MethodsDepth integrated field samples were colleted during 2005-2007 in the upper San Joaquin River in accordance with EERP Field Standard Operating Procedures Protocol Book (Graham 2008). Water samples were colleted in glass 1000 mL bottles (Wheaton Science Products, Millville, NJ), 1000 mL HDPE Trace-Clean narrow mouth plastic bottles (VWR International), 250 mL HDPE Trace-Clean wide mouth plastic bottles (VWR International) as well as 40 mL trace clean vials with PTFE septa (IChem, Rockwood, TN). Bottles were labeled with the appropriate sample number, site name and sampling date. All bottles were rinsed with sample water prior to sample collection. Some sites required a bucket to collect sample water because of accessibility from a high bridge or platform. For these sites, the bucket was pre-rinsed with sample water and sample bottles were filled using a rinsed funnel. Care was taken to distribute water simultaneously to all sample bottles (rather than sequentially). Samples were immediately stored at 4°C after sampling (cooler temperature was recorded in the lab upon delivery) and transported to the EERP lab on the day of sampling.
Within 24 hours of collection samples were transported from the EERP laboratory to the UCD laboratory for analysis, during this time period samples were stored in coolers at 4°C.
Ion chromatography was utilized for measuring Cl- using a Dionex ICS-2000 Ion Chromatograph (Dionex Corporation, Sunnyvale, CA) (SM-4110 B). The reportable limit for this method is 0.02 mg/L Cl- .

Results/DiscussionSamples were measured ranging from 0.0-966.0 mg/L Cl. The average concentration of Cl in samples collected was 143.7 mg/L Cl. These temporal plots (Figures 3-104) created an easy visual way to find outliers and double check data entry for possible mistakes.

Introduction The San Joaquin River (SJR) supports one of the most productive agricultural regions in the world and its productivity is heavily dependant on irrigated agriculture. A consequence of irrigated agriculture is the production of return flows conveyed down gradient drains that eventually discharge to surface waters. Agricultural drainage may have significant nutrient load and can impact algae growth and general water quality in the SJR. Individual farmers and agricultural organizations, such as drainage authorities, are in need of tools to manage the environmental impacts of agricultural activities (Stringfellow, 2008).
For the years 2005 through 2007, sites throughout the San Joaquin Valley watershed were sampled to assess the overall water quality in the region. One thousand nine hundred and ninety-six (1996) individual surface water samples were collected and analyzed and WQ was assessed at 113 locations in the SJR basin (Borglin et al., 2008). Samples were processed and analyzed by the Environmental Engineering Research Program (EERP) laboratory at the University of the Pacific as well as at the University of California, Davis, Dahlgren Lab. This report includes temporal graphs of calcium (Ca) data analyzed by the UCD Dahlgren laboratory between 2005 and 2007.
MethodsDepth integrated field samples were colleted during 2005-2007 in the upper San Joaquin River in accordance with EERP Field Standard Operating Procedures Protocol Book (Graham 2008). Water samples were colleted in glass 1000 mL bottles (Wheaton Science Products, Millville, NJ), 1000 mL HDPE Trace-Clean narrow mouth plastic bottles (VWR International), 250 mL HDPE Trace-Clean wide mouth plastic bottles (VWR International) as well as 40 mL trace clean vials with PTFE septa (IChem, Rockwood, TN). Bottles were labeled with the appropriate sample number, site name and sampling date. All bottles were rinsed with sample water prior to sample collection. Some sites required a bucket to collect sample water because of accessibility from a high bridge or platform. For these sites, the bucket was pre-rinsed with sample water and sample bottles were filled using a rinsed funnel. Care was taken to distribute water simultaneously to all sample bottles (rather than sequentially). Samples were immediately stored at 4°C after sampling (cooler temperature was recorded in the lab upon delivery) and transported to the EERP lab on the day of sampling.
Within 24 hours of collection samples were transported from the EERP laboratory to the UCD laboratory for analysis, during this time period samples were stored in coolers at 4°C.
Ion chromatography was utilized for measuring Ca2+ using a Dionex ICS-2000 Ion Chromatograph (Dionex Corporation, Sunnyvale, CA) (ASTM D6919-03). The reportable limit for this method is 0.08 mg/L Ca2+ .
Results/DiscussionSamples were measured ranging from 0.0-490.9 mg/L Ca. The average concentration of Ca in samples collected was 66.9 mg/L Ca. These temporal plots (Figures 3-104) created an easy visual way to find outliers and double check data entry for possible
