ABSTRACT

This report presents the results of the U.S. Geological Survey's analytical evaluation program for 7 standard reference samples - T-143 (trace constituents), T-145 (trace constituents), M-140 (major constituents)., N-51 (nutrient constituents), N-52 (nutrient constituents), P-27 (low ionic strength constituents), and Hg-23 (mercury) - that were distributed in September 1996 to 167 laboratories registered in the U.S. Geological Survey sponsored interlaboratory testing program. Analytical data that were received from 140 of the laboratories were evaluated with respect to: overall laboratory performance and relative laboratory performance for each analyte in the seven reference samples. Results of these evaluations are presented in tabular form. Also presented are tables and graphs summarizing the analytical data provided by each laboratory for each analyte in the seven standard reference samples. The most probable value for each analyte was determined using nonparametric statistics.

INTRODUCTION

The U.S. Geological Survey (USGS) conducts an interlaboratory evaluation program semiannually. This program provides a variety of reference materials to accomplish quality assurance testing of laboratories and to provide an adequate supply of samples that contribute to quality control programs of participating laboratories. Natural-matrix reference materials are preferred for use in this interlaboratory evaluation program. A series of samples are prepared and distributed each spring and fall. Occasionally, sediment samples are provided.

The program began in 1962 with a single sample containing major constituents that was prepared from distilled water and reagent grade chemicals. Twenty-three USGS laboratories participated in the 1962 determinations of six analytes in the major standard reference sample (SRS). Since that time, objectives of the program have been to:

(1) evaluate and improve the performance of USGS and other participating laboratories;

(2) provide a library of carefully prepared, homogeneous, stable reference materials for use in the quality control programs of laboratories;

(3) identify analytical problem areas;(4) identify quality assurance needs with respect to environmental analyses and

develop new reference materials to meet these needs; and(5) ascertain the accuracy and precision of analytical methods.

Two hundred fifteen USGS and non-USGS laboratories are registered in the program, which can currently provide eight standard reference sample types:

1. Trace constituents.2. Major constituents.3. Nutrient constituents.4. Low ionic strength constituents.5. Mercury.6. Whole water (water with suspended sediment).7. Acid mine drainage constituents.8. Sediment (bed material) for major and trace constituents.

When sufficient data are available, a most probable value is statistically determined for each analyte in the SRS.

Though this is not a laboratory certification program, participation in this continuing quality assurance program is mandatory for all laboratories providing water-analyses data for USGS data storage or use (publications). Federal, State, municipal, and university laboratories can participate even though they do not provide data to the USGS. Analyses of these SRS provides the means to alert participating laboratories of possible deficiencies in their analytical operations, and also provides reference mater als for in-house quality control programs. Participating laboratories are identified only by a confidential code number.

A library of SRS, from previous evaluations, are available. Participating laboratories can purchase previous SRS for further testing, continuing quality assurance, and quality control programs by contacting:

Purpose and Scope

This report summarizes the analytical results submitted by 140 of the 167 laboratories that requested and were shipped SRS for the January 1997 evaluation (table 1). Not all SRS are requested, nor necessarily analyzed by all the laboratories; nor do all laboratories enrolled in the program participate in each evaluation. Analytical results for the following, which were mailed the week of September 9, 1996, are presented in this report:

T-143 Trace constituentsT-145 Trace constituentsM-140 Major constituentsN-51 Nutrient constituentsN-52 Nutrient constituentsP-27 Low ionic strength constituents (precipitation)Hg-23 Mercury

The USGS requested that analytical results be returned by November 15, 1996 for evaluation and preparation of this report. Each participating laboratory is requested to perform those determinations routinely made on the respective SRS for USGS investigations and to indicate the information was provided, it has been included in the respective data table. The analytical data are represented in w^-ys

that allow participants to evaluate data distribution, scatters, outliers, central tendency, bias, skewness, and method relationships.

Preparation of Standard Reference Samples

All of the SRS used in this evaluation were prepared by personnel of the USGS in Lakewood, Colorado and were analyzed for analyte concentrations and physical property values prior to mailing. A library of reference samples is maintained and can be requested by participating laboratories for use in their quality control programs.

Trace constituent sample T-143 was prepared using water collected from the North Platte River near Windover, Wyoming. The water was pumped through 0.45, 0.2- and 0.1-jam filters, in series, into a 3500-L polypropylene drum. The water was continuously circulated and passed through a 0.1-fom filter and ultraviolet sterilizer for 24 hours. Following this circulation, the water was acidified to pH 1.3 with nitric acid and chlorinated to 5 ppm free chlorine. The trace constituent concentrations were adjusted by adding reagent grade chemicals. The sample was circulated an additional 24 hours prior to bottling.

polypropylene bottles used were acid leached, deionized-water rinsed, and autoclave sterilized.

Trace constituent sample T-145 was prepared using water collected from the Yampa River near Steamboat Springs, Colorado. The water was pumped through 0.45, 0.2- and 0.1-(om filters, in series, into a 3500-L polypropylene drum. The water was continuously circulated and passed through a 0. l-jom filter and ultraviolet sterilizer for 24 hours. Following this circulation, the water was acidified to pH 1.3 with nitric acid and chlorinated to 5 ppm free chlorine. The trace constituent concentrations were adjusted by adding reagent grade chemicals. The sample was circulated an additional 24 hours prior to bottling. During bottling the sample was pumped through an ultraviolet sterilizer and a 0.1-jam filter. The 500-mL polypropylene bottles used were acid leached, deionized-water rinsed, and autoclave sterilized.

Major constituent sample M-140 was prepared using water collected from the Arkansas River near Avondale, Colorado. The water was pumped through 0.45, 0.2- and 0.1-(am filters, in series, into a 1300-L polypropylene drum. The water was chlorinated to 5-ppm free chlorine with sodûn hypochlorite, continuously circulated, and passed through a 0.1-jjm filter and ultraviolet sterilizer for 24 hours prior to bottling. During bottling the sample was pumped through an ultraviolet sterilizer ard a 0.1-fom filter. The 500-mL polypropylene bottles used were acid leached, deionized-water rinsed, and autoclave sterilized.

Nutrient sample N-51 was prepared using water collected from the West Chicago Creek near Idaho Springs, Colorado. These samples were prepared the week prior to the mailing for this SRS evaluat:on. The water was pumped through 0.45, 0.2- and 0.1-jim filters, in series, into a 600-L polypropylene drum and continuously circulated and passed through a 0.1-um filter for 24 hours. The desired nutr: °:nt concentrations were obtained by adding reagent-grade chemicals. The sample was continuously circulated for 24 hours prior to being bottled. The 250-mL polyethylene bottles used were new, amV% acid leached, and deionized-water rinsed.

Nutrient sample N-52 was prepared using deionized water. These samples were prepared the week pHbr to the mailing for this SRS evaluation. The water was pumped through 0.45, 0.2- and 0.1-pm filters, in series, into a 600-L polypropylene drum and continuously circulated and passed through a 0.1 -jam filter for 24 hours. The desired nutrient concentrations were obtained by adding reagent-grade chemicals. The sample was continuously circulated for 24 hours prior to being bottled. The 30-mL glass vials used were new, amber, acid leached, and deionized-water rinsed.

Sample P-27 was prepared in a 400-L polypropylene drum using water collected from the West Chicago Creek near Idaho Springs, Colorado. The water was pumped into the drum through 0.45, 0.2- and 0.1 -urr filters in series. Desired phosphate and fluoride concentrations were obtained by adding reagent-grade chemicals. Prior to bottling, the sample was continuously mixed for 24 hours while being circulated through a 0.1 -)xm filter and an ultraviolet sterlizer. During bottling the sample was pumped through an ultraviolet sterilizer and a 0.1-jom filter. The 500-mL polypropylene bottles used were acid leached, deionized-water rinsed, and autoclave sterilized.

Sample Hg-23 was prepared using water collected from the Fall River near Idaho Springs, Colorado. The sample was prepared in a 190-L polypropylene drum. The river water was pumped into this drum through 0.45, 0.2- and 0.1-(om filters in series. The water was continuously circulated and passed through a 0.1-jom filter and ultraviolet sterilizer for 48 hours. Nitric acid (5-percent, v/v) and dichromate ion (0.05-percent, w/w) were added to stabilize the sample. The desired mercury concentration was obtained by aiding a mercury standard solution. Following an additional 24 hours of circulation, the sample was bottled. The 250- mL glass bottles and tetrafluoroethylene fluorocarbon resin caps used were new, acid leached, and deronized- water rinsed.

LABORATORY ANALYSES

The participating laboratories were asked to determine analytes which are summarized in table 2. The number of analytes varied from 28 in T-143 & T-145 (trace constituents) to 1 in Hg-23 (mercury).

LABORATORY PERFORMANCE RATINGS

To facilitate interlaboratory performance comparisons, laboratory performance ratings, based on the analyses reported for each SRS, are included in tables 4 through 11 in this report. Averages of the analyte ratings and the number of analyte values reported for each SRS are given for each participating laboratory. Laboratory performance for each analyte is rated on a scale 4 to 0, based on the absolute Z- value, as listed below:

Rating______________________Absolute Z-value_____4 (Excellent) 0.00 to 0.503 (Good) 0.51 to 1.002 (Satisfactory) 1.01 to 1.501 (Questionable) 1.51 to 2.000 (Poor)._________________Greater than 2.00

Overall laboratory performance ratings greater than 2.4 are considered satisfactory. Overall laboratory performance ratings between 2.0 and 2.39 are considered marginal; those less than 2.0 are considered poor.

STATISTICAL PRESENTATION OF DATA

Data in this report have been evaluated using nonparametric statistics as described by Hoaghn and others (1983). This statistical approach is a resistant statistic because the median is not influenced by outliers as is the mean in traditional statistics.

Analytical data for each analyte are presented in tabular and graphical forms in tables 12 through 18. Tabulated data for each analyte include the laboratory code number, reported values, analytical method, most probable value (MPV), number of reported values - excluding less than values (N), data range, Z- value, and the F-pseudosigma. (The Z-value is equivalent to the Z-score of traditional statistics, being the number of deviations the reported value is from the MPV. The F-pseudosigma is equivalent to the standard deviation (a) of traditional statistics when the data has a Gaussian distribution.) If an analyte has a sufficient number of determinations by a given method^ usually 7, the F-pseudosigma for that analytical method is reported in the block of data listed for each analyte.

The median value is considered the MPV. Reported values of "less than" are used to establish the median, but are not considered in detennining the data range. The median (midpoint) divides the ordered data into halves and is designated the MPV. The hinges include the middle 50-percent of the data and are the mid-values of the upper and lower halves of the data. (The hinges are similar to quartiles, but are not mathematically equivalent.) The range of data between the upper hinge (Hu) and the lower hinge (HI), the hinge spread (H-spr), is used to calculate the F-pseudosigma, the laboratory performance rating, the upper warning level (UWL) and lower warning level (LWL), the upper control level (UCL) and the lower control level (LCL). The F-pseudosigma is calculated by comparison of the H-spr value to the Gaussian distribution relation; 67.45 percent of the data "hinges" between plus and minus la, resulting in a H-spr of 2 x 0.6745 = 1.349a, This relation allows the calculation of the F-pseudosigma = (H-spr)/1.349. Laboratories reporting "less than" values are not performance rated unless their reported "less than" values are greater than two Z-values from the MPV.

The graphical plot of the reported data is shown in figure 1. The upper and lower boundaries of the graphical plots generally are +3 and -3 F-pseudosigma deviations from the median. (Computer-program

scaling constraints do not permit these boundaries to always be graphed at exactly these values.) The graphical plot is a box plot/control chart with reported values grouped by analytical method in ascenc^ng order of value. Lines designate the MPV, Hu, HI, and the (UWL) and (LWL) at +2 and -2 F- pseudosigma, respectively. "Less than" values are not plotted. The analytical data are presented in ways that allow participants to evaluate data distribution, scatter, outliers, central tendency, bias, skewness, and method relationships.
