A. Problem Statement

The Grand Traverse Bay Watershed Protection Plan, approved by the Michigan Department of

Environmental Quality and EPA, states that sediment and excessive nutrient loading are the two highest

ranking pollutants that are threatening the Grand Traverse Bay watershed. Additionally, invasive species

are a top concern specifically in Grand Traverse Bay.

Evidence of locally increased concentrations of nutrients, and most likely phosphorus, in Grand Traverse

Bay is seen by the increase in the amount of algae and macrophyte beds, which nearly doubled from

1991 (64 areas) to 1998 (124 areas). These numbers were still low overall compared to the size of the

Bay; however, the growths were most concentrated at the south end of West Grand Traverse Bay which

is attributed to rapid development and nutrient flushing from stormwater inputs, and a higher amount of

phosphorus entering the bay. The Grand Traverse Bay Watershed Protection Plan’s implementation task

list states that an aquatic macrophyte bed survey should be revisited every 5 years (to date it has been

almost 10 years since the last survey). This project proposed to complete a current macrophyte bed

survey in the Bay, comparing it to previous studies. Completing this survey will help us to track nutrient

hotspots and assist our implementation efforts to protect the ecosystem of the Grand Traverse Bay

watershed. It is important to note that phosphorus is not the only factor in macrophyte bed growth.

Other factors include temperature, water clarity, and food chain dynamics.

Additionally, the effects of quagga mussels on Grand Traverse Bay’s ecosystem are not yet fully known.

It is well known these mussels can live in colder water and at deeper depths than their predecessors,

zebra mussels. Both mussels are such effective filter feeders that they strip the water of various plankton

that indigenous creatures eat. Some theories state that waste materials from zebra and quagga mussels

(called pseudofeces) are loaded with nutrients and, once excreted, collect on the bottom of the lake and

enrich the sediment there. This nutrient-rich bottom sediment, combined with the fact that the highly

efficient mussels clarify the water so much that sunlight can reach normally shaded aquatic plants and

promote their growth, may also be a factor in increasing numbers and sizes of macrophyte beds in Grand

Traverse Bay. Increases of Cladophora and other aquatic plants ultimately result in increased decaying

plant matter in the Bay. This decomposition can then create an oxygen-deprived (anoxic) environment.

Recently Grand Traverse Bay has begun to experience the effects of Type E Botulism on local

waterfowl. Nearby, the Sleeping Bear Dunes National Lakeshore has unfortunately been experiencing

heavy die-offs of waterfowl due to Type E Botulism. The Botulism toxin is produced by the active

bacteria Clostridium botulinum in the nutrient-rich, anoxic conditions in thick mats of decaying

cladophora in Lake Michigan off the National Lakeshore and is passed to round gobies (an invasive

species) that are thriving there. The infected gobies are eaten by various types of birds, who then get

Botulism poisoning themselves and die. Thousands of birds washed up dead on the Western shore of

Michigan in 2006 and 2007. This cycle is now starting to happen in Grand Traverse Bay. In 2007, The

Watershed Center (TWC) received reports of at least 100 bird deaths in the Bay due to Botulism (various

species of birds including ducks, common loons, grebes, seagulls, scoters, and terns). This epidemic in

Northwest Lower Michigan has affected all types of birds, even bald eagles and piping plovers, two of

Michigan’s most beloved bird species. The attenuation and growth of macrophyte beds (cladophora),

along with the spread of zebra/quagga mussels and their effect on the benthic ecosystem needs to be

researched in the Bay in order to effectively track the coming spread of Botulism poisoning.

Data from TWC’s online water quality database and recent DEQ studies reveal a steady decline in

phosphorus levels in the Bay, in fact some of the lowest in the Great Lakes. However, most phosphorus

measurements taken in Grand Traverse Bay have been surface/open water samples and not much is

known about phosphorus levels in the benthic zone of the Bay. Additionally, considering the fact that

benthic studies on sediment in Grand Traverse Bay are lacking, we are proposing to analyze both

sediment and water samples from the bottom of Grand Traverse Bay, under locations where extensive

macrophyte beds exist. Results from these analyses may support theories of nutrient enrichment of

sediment due to zebra/quagga mussels and point to phosphorus ‘hotspots’ due to stormwater runoff in

the water column. For comparison, we analyzed lake-bottom sediment samples in locations free of

macrophyte growth, noting in both instances the presence or absence of zebra and/or quagga mussels. In

addition to sampling at verified macrophyte beds, we also proposed to take sediment samples at the

mouths of major tributaries into Grand Traverse Bay (i.e. Boardman River, Mitchell Creek, Acme Creek,

etc.) to further expand benthic knowledge and gain a baseline value of nutrient levels.

B. Proposed Work

The Watershed Center conducted a macrophyte bed survey in Grand Traverse Bay in order to compare

2009 growth and densities to studies conducted more than 10 ago, as well as analyze sediment and water

samples from three areas in the Bay in order to gain a better understanding of the ecosystem dynamics

between invasive species (zebra/quagga mussels), phosphorus cycling, and plant growth as it relates to

recent botulism outbreaks in the Bay. Specific outcomes of the project included:

Completed 2009 macrophyte bed survey of Grand Traverse Bay.

Identified changes in macrophyte bed distribution and size in Grand Traverse Bay since 1991 and

1998.

Completed sediment and water chemistry analyses at three location types in the bay: mouths of

major tributaries, macrophyte beds, non-macrophyte beds.

Dissemination of project results - posting water quality information to our online water quality

database (www.gtbay.org/wqdb.asp) and publicizing a summary of findings to various sources

(i.e., TWC newsletter and website, press releases, presentations).

Specific Tasks from the Work Plan are as follows:

Macrophyte Bed Survey

A. Plot macrophyte beds from 1998 survey onto map using GPS locations.

B. Obtain aerial photography along Grand Traverse Bay shoreline taken from an altitude where

macrophyte beds can be seen. Shots will include landmarks and overlap with one another so

general locations can be determined. (Anderson Aerial Photography)

C. Utilize aerial photography to assist in locating and field checking macrophyte beds identified

in the 1998 survey to determine existence and current size, as well as identifying recently

formed beds. The survey will be modeled after the 1998 survey in order for comparisons to

be made. At each bed site measured parameters will include: GPS coordinates, location

description, estimated size of bed, dominant vegetative species, relative density (dense,

sparse, intermittent), and estimated depth. We will utilize TWC’s Bay Monitor tugboat to

complete this task.

C. Results and Discussion

Macrophyte Bed Survey

Aerial photography, obtained by Anderson Aerial Photography, along Grand Traverse Bay shoreline was

taken from an altitude where macrophyte beds could be seen. It should be noted that the QAAP and

work plan infer that we would visit the previously identified beds from 1998 first, noting any new ones

using the aerial photography and field observations. However, we did not specifically identify and visit

the 124 beds from 1998 survey first. Once aerial photographs were taken in Summer 2009, we realized

there were many more beds than we expected and it would be too confusing to differentiate 1998 beds

from new ones while in the field (i.e. if a particular bed was a larger 1998 bed, or if it was a new one).

This might more effectively be done after the data was digitized into a GIS data layer, if deemed

necessary. Once beds were

identified they were visited

and verified via boat. At each

bed site measured parameters

included: GPS coordinates

(multiple points taken at

beginning, middle, and end at

all beds), location

description, estimated size of

bed, dominant vegetative

species, relative density

(dense, sparse, intermittent),

and estimated depth.

Sample of aerial

photography used to identify

macrophyte beds.

GPS locations for all identified beds were entered into GIS mapping software (ArcMap). Since most of

the bed locations were comprised of numerous GPS points, we combined the multiple GPS points

associated for a certain bed into one single bed location in the GIS data layer. Additionally, we made

another GIS data layer which connected the GPS points and showed the bed as a line; this is convenient

when comparing lengths of beds to one another. The corresponding data for each macrophyte bed

(depth, vegetation present, location description, etc.) was entered into a spreadsheet and added to the

data file associated with bed locations (i.e. you can view the data associated with a particular bed using

the GIS software ArcMap) (Appendix A).

A map showing all recorded macrophyte beds was produced for the 2009 survey, as well as the 1993 and

1998 surveys for comparison (Figures 1, 2, and 3). There were just over 400 macrophyte beds found in

Grand Traverse Bay - some fairly large and some just 10x10 feet. In comparison, the 1998 survey found

just 124 beds, and the 1991 survey found only 64. In the past 11 years, macrophyte bed numbers have

more than tripled in the Bay. However, we are not able to draw exact comparisons between both sets of

data because this study utilized aerial surveys and the previous surveys did not. Meaning, this survey

could have simply found more beds due to the methods used.

The comparison below is a zoomed in area of Suttons Bay. These maps show the explosive growth in

the numbers of beds found over the past 18 years.

1991 - 2 beds 1998 - 9 beds 2009 - 36 beds

Most of the macrophyte beds were concentrated in embayments (Bowers Harbor and Suttons, Omena,

and Northport Bays) and the southern end West Grand Traverse Bay. There were also very large,

extensive beds around the shallow, shoal areas off Lee and Stoney Points. As expected, marinas had

elevated amounts of growth as well. Interesting to note is that we found a lot of bed growth along drop

off areas where the slope was getting steeper, in about 13-20 feet of water. Often times a skinny patch of

growth continued along this

drop-off line for up to 1/4 or

1/2 mile. Sometimes even

longer. By far more beds

were found in West Bay

compared to East Bay. We

believe this is because the

eastern edge of East Bay is

less sheltered from wave

action coming down from

the open waters of Lake

Michigan, in addition to less

development along the

shoreline and the lack of

embayments.

Of note to report is that the southern end of East Grand Traverse Bay was defined by numerous

striations, or ridges, extending in a north-south fashion (see photo below). The tops of the ridges had

aquatic plant growth, and the bottom of the ridge was comprised of sand. Large beds on the east and

south sides of East Bay were marked with GPS coordinates and given a site number, but due to the large

amount of striations and difficulty to map, the plant growth at the southern end of East Bay was not

given a site number. Plant growth observed in these beds was primarily milfoil, with some areas of

pondweed. Our best theory as to why this pattern of plant growth has emerged here is that is somehow

linked to the water currents in the Bay. Further research into this topic would be beneficial.

The vast majority of plant species observed during the survey were Water Milfoil and Chara. Other

plants found were various forms of pondweed. Of note is that virtually no cladophora was found during

the entire survey.

Sediment Sampling and Water Quality Analysis

Sediment and water quality sampling was completed during October and November of 2009. Locations

consisted of 40 locations randomly selected from mapped macrophyte beds and 10 adjacent areas

lacking submerged vegetation (Figure 4).

Sediment samples were analyzed by licensed laboratories for select chemical parameters indicative of

freshwater quality (Appendix B). Chemical parameters analyzed included Total Phosphorous, Kjeldahl

Nitrogen and Total Ammonia/Ammonium. Shallow and deep or “benthic” water samples were analyzed

by licensed laboratories for select chemical parameters indicative of freshwater quality as well

(Appendix C). Chemical parameters analyzed included Total Phosphorous, Total Orthophosphate,

Kjeldahl Nitrogen, Total Ammonia, and Nitrate/Nitrite Nitrogen. General chemistry water quality

parameters were also measured at each of the 50 sample locations using a hand-held electronic

monitoring instrument, known as a Hydrolab™. These parameters consisted of temperature, pH,

dissolved oxygen, turbidity and conductivity (Appendix D).

Sediment and water quality samples were also collected within the nearshore environment of each of

seven (7) major surface water tributaries to Grand Traverse Bay. These tributaries included Elk River,

Boardman River, Cedar Creek, Mitchell Creek, Acme Creek, Yuba Creek and Leo Creek (Appendix B

and C).

Water Quality Analysis Results - Hydrolab

All results obtained for temperature, pH, Dissolved Oxygen, Turbidity, and Conductivity were well

within normal, expected ranges for Grand Traverse Bay and other oligotrophic waters (Appendix D).

Results did not differ between macrophyte bed and non-macrophyte bed sample locations. Average DO

concentrations in the bay were well above Michigan Water Quality Standards (coldwater fishery: 7mg/L;

warmwater fishery: 5mg/L1) (Table 2).

*All results reported in mg/L

An elevated Ammonia concentration was found at the mouth of Cedar Creek in southeastern Elmwood

Township, Leelanau County relative to the other tributaries sampled. This is still below the US EPA

established water quality criteria (2 mg/L) based on threats to aquatic organisms, including fish.2

Ammonia concentration in surface water at this location indicated a concentration of approximately

0.35 mg/L, or approximately four times the average of other major surface water tributaries to Grand

Traverse Bay.

Water Quality Analysis Results - Phosphorus

Some scientists categorize inland freshwater lakes production or “trophic” levels according to Total

Phosphorous (TP) concentrations in surface waters.3 Lakes with TP concentrations below 0.010 mg/L

are classified as oligotrophic (high water quality, low level of biologic productivity); between 0.010 and

0.020 mg/L as mesotrophic (moderate water quality and biologic productivity); and over 0.020 mg/L as

indicative of eutrophic lakes (low quality, and high biologic productivity). Phosphorus samples

collected in the Bay were low and within the oligotrophic range (Appendix C, Table 4, Figure 5).

Results of Grand Traverse Bay surface and bottom water sampling at macrophyte beds and non

macrophyte bed areas did not indicate any significant variation in concentrations of TP within the

surface water column.

Of note is that the only TP concentration measured in the mesotrophic range was in a benthic water

sample location 25 (immediately west of, adjacent to and outside of the harbor at the Great Lakes

Maritime Academy at the foot of West Grand Traverse Bay in Traverse City). This site indicated a

concentration of TP of 0.014 mg/L, almost mid-way between mesotrophic and eutrophic. This could be

caused by outflow from the Boardman River.

16

To control eutrophication, the U.S. EPA recommends that TP not exceed 0.05 mg/L in a stream at a

point where it enters a lake or reservoir.4 Results of water sampling for TP for major tributaries to

Grand Traverse Bay do not indicate any exceedances of this water standard. However TP concentrations

in water samples collected at the mouth of the Boardman River, Mitchell Creek and Yuba Creek

(Appendix D, Table 4, Figure 5), indicate elevated levels of TP as compared to samples taken from Elk

River, and Acme, Cedar and Leo Creeks (more than twice as high).

Sediment Analysis Results - Nitrogen

The U.S. EPA has established water quality criteria for ammonia in surface waters based on threats to

aquatic organism, including fish. These criteria vary with surface water acidity and temperature, both of

which affect ammonia toxicity in its various chemical forms. In most fresh waters, total Ammonia

concentrations in sediments above 40 mg/kg are derived as exceeding chronic exposure criteria for fish

(i.e. 20 times the U.S. EPA water quality standard for Ammonia).5 Results of tributary sediment

sampling do not indicate any exceedances of this derived sediment standard. However, Ammonia

concentrations in sediments at the mouth of Yuba Creek north of Acme indicated a concentration of 39.6

mg/kg, which falls just below the EPA standard (Appendix B, Table 5, Figure 6).

Results of Grand Traverse Bay sediment sampling for Ammonia indicated concentrations of Ammonia

above this derived sediment threshold at just three sites, all of which were at macrophyte beds

(Appendix B, Table 5, Figure 6). These sites were: #12 - SW corner of West GT Bay, by yacht club;

#246 - Northport Bay; and #156 - off Lee Point. All of these sites had elevated TP levels in sediment as

well (discussed later). Average Ammonia concentrations at macrophyte sites was 17.77 mg/kg, whereas

non-macrophyte bed sites averaged just 1.09 mg/kg (Table 5, Figure 6). This suggests that sediment

Ammonia concentrations are associated with some macrophyte bed areas within East and West Grand

Traverse Bay.

Elk River and Acme Creek show elevated Kjeldahl Nitrogen (TKN) values in sediments when compared

to other tributaries monitored, especially Acme Creek, which measured at 480 mg/kg (Table 5, Figure 7).

Additionally, average TKN concentrations at macrophyte sites was 336 mg/kg, whereas non-

macrophyte bed sites averaged just 95.7 mg/kg (Table 5, Figure 7). This suggests that sediment TKN

concentrations are associated with some macrophyte bed areas within East and West Grand Traverse

Bay.

Sediment Analysis Results - Phosphorus

The U.S. Geological Survey considers TP concentrations above 1.0 mg/kg or parts per million in

sediments to result in decreased water quality at points in which a stream or river tributary enters a lake

or reservoir.6 Results of tributary sediment sampling for TP do not indicate any exceedances of this TP

sediment standard. However it is worth noting that TP concentrations in sediments at the mouth of Leo

Creek at Suttons Bay indicated a concentration of 0.72 mg/kg, which could be considered slightly

elevated for the purposes of this study, when compared to the average concentration of 0.47 mg/kg

(Table 5).

Some scientists categorize inland freshwater lakes production or “trophic” levels according to TP

concentrations in sediments.7 Lakes with TP concentrations below 0.2 mg/kg are classified as

oligotrophic or (high water quality, low level of biologic productivity); between 0.2 and 0.4 mg/kg as

mesotrophic (or moderate water quality and biologic productivity); and over 0.4 mg/kg as indicative of

eutrophic lakes (low quality, and high biologic productivity).

Results of Grand Traverse Bay sediment sampling for TP at macrophyte beds indicated concentrations

above this eutrophic threshold at 21 sites (52.5%), mesotrophic conditions at 4 sites (10%), and

oligotrophic conditions at15 sites (37.5%) (Table 6, Figure 8). All of the eutrophic sites were in West

Grand Traverse Bay (Figure 9). Results of sediment sampling at non-macrophyte bed areas indicated no

TP concentrations above the eutrophic threshold, 2 within the mesotrophic threshold, and the remaining

8 samples in the oligotrophic range (Figure 8, Appendix B).

Notably, Total Phosphorous concentrations at sample point #156 (due south of Lee Point, West Grand

Traverse Bay) indicate highly elevated concentration of TP at nearly 4.0 mg/kg or about ten times the

eutrophic threshold. This sample could be considered an outlier due to likely laboratory and/or sample

collection error, but was not rejected in statistical assessments in this report (i.e. when calculating

averages seen in tables).

Average concentrations of TP within sediments at macrophyte bed locations was 0.65 mg/kg, and

0.10 mg/kg at locations lacking rooted aquatic or “macrophyte” vegetation (Table 5). Comparing

average TP concentrations at macrophyte and non-macrophyte bed areas suggests that macrophyte bed

locations are indeed associated with locations with higher concentrations of TP in sediment. The

calculations take into account the large number of sites where TP analysis registered as non-detect: 14

macrophyte bed sites and 7 non-macrophyte bed sites. When calculating average values on TP for each

location a value of 0 mg/kg was used for non-detect sites. However, if you take out all sites where TP

was not detected and just use sites where a value was obtained, average TP sediment concentrations at

macrophyte bed locations was 1.0 mg/kg and 0.32 mg/kg at non-macrophyte bed sites. These

comparisons suggest that higher TP sediment concentrations are associated with some macrophyte bed

areas within East and West Grand Traverse Bay (Table 5, Figure 8, Appendix B).

D. Conclusions The results of this study should be considered as indicative of baseline conditions of Grand Traverse

Bay in 2009 (i.e. macrophyte bed location, size and type; sediment and water quality nutrient

concentrations and general chemistry; location of zebra mussels, etc.) to be compared to subsequent

studies. Macrophyte bed numbers in Grand Traverse Bay have more than tripled in the past 11 years

(124 beds in 1998 to 402 beds in 2009). Most of the macrophyte beds were concentrated in embayments

(Bowers Harbor and Suttons, Omena, and Northport Bays) and the southern end of West Grand Traverse

Bay. There were also very large, extensive beds around the shallow, shoal areas off Lee and Stoney

Points.

The reason for the increase in numbers of macrophyte beds could be due to a number of factors. In the

past 11 years since the last survey was completed there has been an increase in the amount of shoreline

development, which could therefore increase the amount of stormwater input and fertilizers to the Bay.

Additionally, the invasive zebra and quagga mussels have grown in numbers - the mussels filter water,

making it clearer so light penetrates deeper to spur plant growth. Waste from the mussels is high in

Phosphorus, which could be increasing the concentrations of Phosphorus in the sediments, causing more

plant growth as noted below.

The vast majority of plants found in the study were chara and milfoil, with some other various forms of

pondweed. Virtually no cladophora was found in the entire survey. How this impacts the likelihood of

avian botulism affecting Grand Traverse Bay is unknown. The major plant type found off of Sleeping

Bear Lakeshore of cladophora, but whether that is the determining factor in the cycle and occurance of

avian botulism is unknown. It could be that excessive growth and die-off of any plant species will feed

the botulism cycle, or perhaps it is the specific occurrence of cladophora that is necessary. Previous

cases of avian botulism have mostly been noted in East Grand Traverse Bay, where there are fewer

macrophyte bed found, and no cladophora noted.

Water testing results suggest that water quality within the Grand Traverse Bay is excellent - Phosphorus

levels in water samples were low overall in the Bay, and did not vary much between surface and bottom

samples and between areas with and without macrophyte beds. This held true as well with Hydrolab

data acquired.

However, elevated nutrient levels in some sediments were found. Total Phosphorus, Ammonia, and

Kjeldahn Nitrogen concentrations in sediments were generally higher in macrophyte beds areas than in

sediments taken from non-macrophyte bed areas.

Areas indicating elevated levels of nutrients in sediments relative to other portions of Grand Traverse

Bay were found to include areas at:

Off Bryant Park, by Northwestern MI College dock (TP only)

Within the southwestern portion of West Grand Traverse Bay (TP, Ammonia)

South of Lee Point (TP, Ammonia), Northwest side of Stoney Point (TP only)

Omena Point and southern end of Omena Bay (TP only)

Page 24: FINAL PROJECT REPORT Date: 4/28/10 · The Grand Traverse Bay Watershed Protection Plan’s implementation task list states that an aquatic macrophyte bed survey should be revisited

24

Areas indicating slightly “elevated” levels of nutrients in surface water were found to include discharge

at the mouths of the Boardman River (TP), Cedar Creek (Ammonia), Yuba Creek (TP), and Mitchell

Creek (TP); and an area near the harbor at the Great Lakes Maritime Academy in Traverse City (benthic

TP, measured in mesotrophic range). Areas of elevated nutrients within the water column were not were

found to be associated with the location of macrophyte beds.

It should also be noted that it was extremely difficult to obtain zebra mussel densities within macrophyte

bed areas because of the dense plant growth - the bottom of the Bay often could not be seen through the

dense growth. However, in general, whenever we found a macrophyte bed zebra/quagga mussels were

in fact present. Large clumps were seen on the ground, and smaller clumps were noted growing among

milfoil strands higher up.

Two things to take into account in this study are 1) the low number of non-macrophyte bed locations

sampled (10) as compared to macrophyte beds (40), and 2) the time of year in which water and sediment

anlyses took place. When planning our study we did not foresee that there would be such a large

increase in the number of macrophyte beds over the last 11 years. When outlining the work plan we

stated that we would sample at least 10% of the found macrophyte beds and at least 10 non-macrophyte

bed areas. When planning the sampling budget we estimated that there would be around 24 samples.

However, over 400 beds were found and we had to sample 40. Fortunately additional funding from the

National Fish and Wildlife Foundation was available to us in order to help with some of the sampling

costs, but after planning the budget for 50 samples, we could not fit in any additional sites. We suggest

that additional studies of this nature incorporate more non-macrophyte bed sites for better comparison

between the two location types.

Weather and time constraints forced us to extend our water and sediment sampling into late Fall of 2009.

The initial macrophyte bed survey took longer to complete due to undesirable weather and the sheer

number of beds to categorize. The survey itself was not completed until late September 2009. By the

time we chose our sites for sediment and water analyses the weather was becoming more unfavorable

and it was difficult to find days we could safely go out on the boat and take the samples.

It is recommended that the approaches and methods used in this study be repeated periodically every 5

years to monitor the long term changes in macrophyte bed numbers and distribution, as well as sediment

and water quality concentrations associated with plant growth in Grand Traverse Bay. Further

investigation should be made into the differences in nutrient concentration in sediments associated with

macrophyte and non-macrophyte bed areas. Since nutrient concentrations may fluctuate over the course

of a year it is recommended that sediment testing at the existing chosen sites be completed during

different times of the year, as well as adding more non-macrophyte beds sites to test as a comparison.

Finally, it is recommend that site specific investigation be undertaken to determine the source or sources

of slightly elevated nutrients in locations identified in this study, and that work be completed to solve

any nutrient sources found at those locations.

* Can see lower than Reporting Limit because of Method Detection Limit Provided by SOS Analytical: The METHOD DETECTION LIMIT (MDL) is a statistically calculated number. The practical method for determining the MDL is to analyze 10 samples of concentration near

the expected limit of detection. The standard deviation is then determined. The one-sided t-distribution is determined and multiplied versus the determined standard deviation. The result is called 99% confidence interval. The MDL must be less than the LOD or PQL (see below). The Practical Quantitation Limit (PQL) is often referred to as the Limit of Detection (LOD). The LOD is defined simply as about 5-10 times the MDL. The LOD is the lowest point on the standard curve that is used to analyze a set of samples.
