Quantity and Quality Of Base Flow and Stormwater Runoff in Independence, Missouri-October 1991 to February 1993
ByGreggK. Schalk
AbstractSamples were collected in October 1991
and January to February 1992 at 193 sampling sites to characterize base flow in Indepen dence, Missouri. From all samples collected at the base-flow sampling sites, 5 samples exceeded a pH of 9.0, total chlorine was detected in 45 samples, total detergents were detected in 1 sample, and total copper and total phenols were not detected in any samples.
Samples were collected from July 1992 to February 1993 at five stormwater-runoff sampling sites draining single-family, multi- family, commercial, and light-industrial land uses. Fecal coliform ranged from 500 to 290,000 colonies per 100 milliliters and fecal streptococci ranged from 1,900 to 500,000 colonies per 100 milliliters in 35 first-flush samples collected from 15 storms at the 5 sampling sites. The fecal coliform to fecal streptococci ratio averaged 0.9 and ranged from 0.01 to 4.1.
At each stormwater-runoff sampling site, three flow-weighted composite samples were collected and analyzed for physical properties, common constituents, trace elements, pesti cides, volatile organic compounds, and acidic, basic, and neutral semi-volatile organic compounds. Runoff loads were calculated for each constituent detected. The chemical oxygen demand ranged from 36 to 1,600 milli grams per liter. Biochemical oxygen demand ranged from 15 to greater than 650 milligrams per liter. Dissolved solids concentrations ranged from 34 milligrams per liter at a
commercial site to 14,700 milligrams per liter at a light-industrial site that had large unshel tered piles of road salt. For all sites suspended solid concentrations ranged from 38 to 1,200 milligrams per liter.
Antimony, beryllium, selenium, and thallium were not detected, and silver was detected once. Mercury was detected with concentrations of 0.1,0.2, and 0.3 microgram per liter. The following ranges of trace element concentrations (micrograms per liter) were detected: arsenic (1 to 10), cadmium (less than 1 to 40), chromium (less than 1 to 99), copper (8 to 130), lead (20 to 800), nickel (3 to 37), and zinc (110 to 6,200).
Pesticides detected include chlordane, p,p' -ODD, p,p' -DOT, diazinon, dieldrin, lindane, and Aroclor 1254. Thirteen of the 63 volatile organic compounds analyzed were detected 27 times with concentrations ranging from 0.2 to 5.1 micrograms per liter. Acidic, basic, and neutral semi-volatile organic compounds detected include di-2-ethylhexyl phthalate, fluoranthene, phenanthrene, and pyrene.
INTRODUCTION
During 1990 the U.S. Environmental Protection Agency (USEPA) mandated that all cities with a population of 100,000 or greater be required to submit a Stormwater discharge permit application under the National Pollution Discharge Elimination System (NPDES) program. The purpose of the permit is to establish an approach to
control pollutants in stormwater (U.S. Environ mental Protection Agency, 1990). The permit application requires characterization of water discharges to the municipal storm sewer system. The U.S. Geological Survey (USGS), in cooper ation with the city of Independence, Missouri, began a study in July 1991 to:
1. Characterize the quantity and quality of water discharging (base flow) from selected conveyances within the city limits of Independence during dry-weather periods.
2. Characterize the quantity and quality of stormwater runoff from five selected homogenous land-use basins in Independence.
Purpose and Scope
The purpose of this report is to document site descriptions, data collection techniques, and laboratory analytical methods and to present the water quantity and quality results collected from base-flow sampling from October 1991 to February 1992 and from stormwater runoff from July 1992 to February 1993.
The scope of this report includes measure ments of discharge, specific conductance, pH, and water temperature and concentrations of total chlorine, total copper, total detergent, and total phenols from 226 samples collected at 193 sites preceding 72 hours of dry weather. This report also includes results from stormwater runoff analyzed for bacteria, physical properties, common constituents, trace elements, pesticides, volatile organic compounds, and semi-volatile acidic, basic, and neutral methylene chloride extractable organic compounds (hereafter referred to in this report as acidic, basic, and neutral organic compounds) from 15 storm samples from 5 urban land-use sites. Stormwater runoff volume and loads were calculated for each storm at each site. Volume and loads were simulated using data from this report and methods described by Driver and Tasker (1990).
eastern side of the Kansas City metropolitan area adjacent to the eastern city limits of Kansas City, Missouri. During 1990 the population of Indepen dence was 112,301 (City of Independence, 1993).
Independence occupies about 78 mi2 (square miles) and is primarily a suburban community with commercial areas developed along the arterial streets. Independence is composed of 59 percent urban land and 41 percent non-urban land (agricul tural and undeveloped land). Of the urban land 61 percent is single-family residential, 6.1 percent is commercial, and 2.4 percent is multi-family residential. The only heavy industrial area is limited to the Lake City Army Ammunition Plant, which is 12.6 percent of the urban land use. Light industrial land uses cover 1.9 percent of the urban land use, and a vacant-surface, industrial underground site covers 2.2 percent of urban land use. The remaining 14 percent of the urban land use includes public facilities, municipal waste facilities, and golf courses.
The average annual precipitation for the area is 35.2 in. (inches; National Oceanic and Atmospheric Administration, 1991). Of the annual precipitation, an average of 24.4 in. occurs during April through September. The mean minirnum January temper ature in the study area is 17.2 °F (degrees Fahrenheit), and the mean daily maximum July temperature is 88.5 °F. The 24-hour, 2-year recur rence-interval rainfall is 3.5 in. (Hershfield, 1961).
All of the larger streams in Independence drain north into the Missouri River. These larger streams include Fire Prairie Creek, Little Blue River, Mill Creek, Rock Creek, and Sugar Creek (fig. 1). The Little Blue River and its tributaries drain about two- thirds of the city. The tributary streams of the Little Blue River that drain Independence include Adair Creek, Bundschu Creek, Burr Oak Creek, Crackerneck Creek, East Fork Little Blue River, and Spring Branch Creek (fig. 1). Ditches, gutters, curbs, swales, and ephemeral stream tributaries drain a major part of the developed area to the perennial streams. Subterranean storm sewers drain newly developed areas, main arterial roads, and densely populated areas.

BASE-FLOW SAMPLING METHODS
To determine quantity of water discharging and selected constituent concentrations during base flow (referred to by the USEPA as dry-weather screening) into the streams of Independence, samples were collected in all basins. These samples were collected after 72 hours of no precip itation to ensure that water sampled was not from stormwater runoff.
Site Selection
Because perennial streams and other open- channel conveyances drain most of Independence, a systematic procedure was developed to locate sampling sites based on these drainage character istics. This procedure identified sites in convey ances with base flow. Sample sites were selected at the farthest downstream point in each stream basin that had a cross section adequate for a discharge measurement. Site selection continued upstream until no flow was present. Upstream sample sites were located at flowing outfalls, upstream from flowing outfalls, at the mouth of flowing tributaries, upstream from flowing tribu taries, and at selected sites along the stream. Base- flow sampling sites were established at 193 points in the city limits of Independence (fig. 2).
Data Collection
Discharge and water-quality data were collected at the 193 samples sites (fig. 2). Discharge, specific conductance, pH, water temperature, and concentrations of total chlorine,
total copper, total detergents, and total phenols were measured either onsite or within 48 hours of sample collection. Discharge was measured using either volumetric methods or by a pygmy current meter (Rantz and others, 1982). Specific conduc tance was measured within 48 hours after sample collection at the USGS in Independence with a meter calibrated in the range encompassing the water sample and reported in microsiemens per centimeter at 25 °C (degrees Celsius). The pH of the water was measured at the time of collection with an electronic meter calibrated in the pH range of 4.0 to 10.0. Water temperature was measured at the time of collection using a mercury thermometer and reported to the nearest 0.5 °C.
Concentrations of total chlorine, total copper, total detergents, and total phenols were measured using colorimetric reagents and methods developed by the Hach Company 1 . Total chlorine concentra tions were determined at the time of collection. Concentrations of total copper, total detergents, and total phenols were determined at the USGS in Independence within 48 hours from the time of sample collection. The Hach methods are considered semiquantitative because no quality assurance samples were collected to verify the precision and accuracy of the analytical methods.
STORMWATER-RUNOFF SAMPLING METHODS
To determine the quantity and quality of stormwater runoff, discharge and rainfall depths were measured and water-quality and quality assurance samples were collected and analyzed. Constituent loads were computed for each constituent detected. The data collected for this study are stored in the USGS National Water Data Storage and Retrieval System (WATSTORE).
Site Selection
Sites 1 to 5 (fig. 1) were selected for the purpose of monitoring water quantity and quality from stormwater runoff from specific land uses

within Independence (table 1, at the back of this report). Site 1 is downstream from a single-family housing area, site 2 from a multi-family housing area, sites 3 and 4 from commercial areas, and site 5 from a light industrial area. Selection of each study site was based on homogenous land use, suitable hydrologic controls for a reliable stage to discharge rating, and accessibility and safety.
Drainage and impervious areas for the study sites were computed from the topographic planning maps on file with the city of Independence and site visits. Land-use percentages were computed using a geographical information system data base of land-use coverages compiled by Independence and visits for sites 1 to 4. Site 5 land-use data were computed using topographic planning maps and site visits.
Site 1 (fig. 1) is downstream from a fully developed single-family housing area. The basin drains 86 percent single-family housing, 4 percent commercial, 4 percent multi-family housing, 3 percent light industrial, and 3 percent public facil ities. The approximate population density in the basin is 3,810 persons per square mile (City of Independence, 1993). Street gutters, ditches, and natural open channels are the primary conveyances that drain this basin. The stage to discharge relation is controlled by a culvert at high flow and by the stream channel at low flow.
Site 2 (fig. 1) is downstream from a multi- family housing area. This basin primarily has residential dwellings consisting of apartments and duplexes. The basin drains 69 percent single and multi-family housing, 17 percent commercial, and 14 percent vacant land. The population density in the basin is approximately 5,062 persons per square mile (City of Independence, 1993). Street gutters and underground storm sewers are the primary conveyances that drain this basin. The stage to discharge relation is controlled by a culvert at high flow and by the stream channel at low flow.
Site 3 (fig. 1) is downstream from a commercial area. This basin has various types of commercial facilities, including a large retail store, two strip malls, several restaurants, convenience stores, a car wash, and a storage facility. State Highway 291 crosses the basin. The basin drains 62 percent commercial land use, 24 percent single- family housing, 9 percent multi-family housing,
and 5 percent public facilities. The population density in the basin is approximately 2,324 persons per square mile (City of Independence, 1993). Gutters and underground storm sewers are the main conveyances that drain the area. The stage to discharge relation is controlled by a culvert at high flow and by the stream channel at low flow.
Site 4 is downstream from the downtown commercial area of Independence. The basin drains approximately 53 percent single-family housing, 24 percent commercial, 16 percent public facilities, 5 percent light industry, and 2 percent multi-family housing. The population density in the basin is approximately 3,739 persons per square mile (City of Independence, 1993). Gutters and underground storm sewers are the main conveyances that drain the area. The stage to discharge relation is controlled by a culvert at high flow and by the stream channel at low flow.
Site 5 is downstream from a light industrial area. The basin drains 71 percent light industry, 22 percent vacant ground, and 7 percent salt-pile storage area for road deicing. No residential housing exists in this basin. Overland flow, gutters, and underground storm sewers are the main conveyances that drain the area. For this site, the stage to discharge relation control is a man- made grass-lined channel.
Data Collection
Continuous-streamflow records at the five stormwater-runoff sampling sites were collected with a float and stilling-well combination (Buchanan and Somers, 1978). Continuous stream stage was recorded in 5-minute increments. Stage also was collected manually while sampling storm- water runoff. Stage data were collected at 0.01 -ft (foot) increments. Stream stage was related to current-meter streamflow measurements (Buchanan and Somers, 1976) and to indirect measurement computations (Benson and Dalrymple, 1967) to prepare stage-discharge ratings (Kennedy, 1983). Indirect measurement computations for culverts (Bodhaine, 1976) were made at sites 1, 2, 3, and 4. Indirect measurement computations using the slope-area method (Dalrymple and Benson, 1967) were made at site 5.

Continuous rainfall data were collected at two USGS sites, RN1 and RN2 (fig. 1). Rainfall data- collection sites were chosen to represent depths of rainfall at the sampling sites (table 1). Criteria for selecting rain gage locations included geographical location and overhead clearance above rain gage. The instrumentation for a rain gage included a 5- minute-interval analog data recorder connected to a float inside a rainfall collection pipe. Rainfall data were collected at 0.01-in. increments.
Stormwater runoff was sampled at least 72 hours after the previous storm of 0.1 in. or more of rain. Samples were either collected at one location in the stream or at several locations across the stream at equal width increments. Stormwater- runoff samples were collected using a hand-held bottle.
Stormwater-runoff samples for physical properties, inorganic compounds, and organic compounds were of two types. Within the first 30 minutes of runoff, samples were collected for bacteria, total chlorine, cyanide, phenols, and oil and grease in the approved bottle (tables 2 and 3, at the back of this report; the sample for bacteria analysis was collected in a sterilized polyethylene bottle). Collectively, these samples are classified as the first-flush sample. Within the first 30 minutes and also throughout the duration of the runoff, a discrete sample was collected for a flow- weighted-composite sample. The discrete sample was collected directly into a 1-gal (gallon) narrow- mouth brown glass bottle for analyses of all constituents except volatile organic compounds. The discrete sample for volatile organic compound analysis was collected in a 40-mL (milliliter) brown septum-capped bottle. To compute the volume of each discrete sample to be included in the flow-weighted-composite sample, the following method used was based on the mid- interval method of subdividing described by Porterfield (1977) and adjusted to account for variable time intervals:
(1)
where v(n) is the volume of discrete sample to be added to the composite sample;
q(n) is the total volume of discharge that occurred from one-half the time since the previous sample until one- half the time to the next sample. The first sample volume is computed from the beginning of the storm- water runoff to one-half the time to the second sample. The last sample volume is computed from one-half the time since the previous sample to the end of the stormwater runoff;
Q is total volume of stormwater runoff;and
V(t) is total composite volume required. The 1-gal discrete samples were composited at
the USGS, Independence, within 24 hours of collection to obtain the flow-weighted composite sample. This sample was split into subsamples using a cone splitter and a churn splitter for the different preservation and analytical methods. The cone splitter was used to initially split the composite sample into 10 subsamples within a 3 percent equal volume and suspended sediment concentration (Ward and Harr, 1990). From these 10 subsamples, samples for organic compounds were split using the cone splitter and samples for inorganic compounds were split using the churn splitter. The 40-mL discrete samples for volatile organic compound analysis were composited at the USGS, Arvada, Colorado.
Volume and Loads
A volume is the total quantity of water contributed from a basin by stormwater runoff passing a designated point in a given period of time. A volume was calculated for the duration of stormwater runoff using the discharge hydrograph. A load is the total quantity of a particular constituent contributed from a basin by stormwater runoff passing a sample point in a given time.

Simulated stormwater-runoff volumes in cubic feet and stormwater-runoff constituent loads in pounds were calculated using the regional regression models for the stormwater-runoff volume and loads presented in Driver and Tasker (1990). Site specific, climatic, and storm charac teristic data from this report were used with the regression models to simulate stormwater-runoff volume and loads. For each site the physical and land-use information needed to simulate a storm- water-runoff volume or load included drainage area, percentage of impervious area, population density, and percentage of land use, including residential, commercial, industrial, and non- urban. The climatic characteristics needed to simulate a stormwater-runoff volume or load were total storm rainfall, maximum 24-hour precipi tation intensity that had a 2-year recurrence interval, mean annual rainfall, mean annual nitrogen load in precipitation, and mean minimum January temperature. For this study, stormwater- runoff volume and loads were simulated using measured total rainfall from storms sampled. The approximate mean annual nitrogen load in precipi tation is 13.3 pounds per acre [National Atmospheric Deposition Program (IR-7)/National Trends Network, 1982-91]. The regression models simulated stormwater-runoff loads for chemical oxygen demand, dissolved and suspended solids, total nitrogen, total ammonia plus organic nitrogen, and total cadmium, copper, lead, and zinc.
Laboratory Analysis
Water temperature, fecal coliform, fecal strep tococci, and concentrations of total chlorine, total cyanide, total phenols, and total oil and grease were determined for the first-flush sample. Water temperature and total chlorine concentration were determined at the time of sample collection using methods described for base-flow sampling. Fecal coliform and fecal streptococci colony densities were determined using membrane-filter methods described in Britton and Greeson (1989) at the USGS in Independence. Samples for total phenols and total oil and grease were analyzed by the USGS, Arvada, Colorado, using the methods and detection limits listed in table 2. Total cyanide
was analyzed by Enseco Rocky Mountain Analytical Laboratory, Arvada, Colorado, using the methods and detection limits listed in table 3.
The physical properties and chemical constituent analyses, methods, and detection limits used by the USGS, Arvada, Colorado for the flow- weighted-composite samples are listed in table 2. Total antimony, total silver, and total thallium concentrations in the flow-weighted-composite sample were analyzed by Enseco Rocky Mountain Analytical Laboratory using methods and detection limits listed in table 3. The 5-day biochemical oxygen demand (hereafter referred to as biochemical oxygen demand) sample from the flow-weighted composite sample was split into a 1-L (liter) polyethylene bottle and analyzed at the city of Independence Water Pollution Control Laboratory, using the USEPA method 405.1 (5 days at 20 °C; U.S. Environmental Protection Agency, 1983) within 24 hours of sample collection.
Chemical constituents reported as total, total recoverable, or whole-water recoverable were analyzed from unfiltered samples. Dissolved constituents from the flow-weighted composite samples were determined from water samples filtered through a 0.45-urn (micrometer) filter using a peristaltic pump.
Analyses of the flow-weighted-composite samples for specific conductance, pH, alkalinity and bicarbonate concentrations were done at the USGS in Independence. Specific conductance and pH were determined by methods described in the base-flow sampling methods. Alkalinity and bicarbonate concentrations were determined by incremental titrations with 0.16 N (normal) sulfuric acid past the inflection point of the titration curve that occurs at a pH of about 4.5.
Quality Assurance Samples
The representativeness of sample collection and handling was assessed by analyzing equipment and trip blanks, replicate samples, and matrix spiked sample sets. An equipment blank was analyzed for all properties and constituents listed in tables 2 and 3, except for biochemical oxygen demand.
11
Organic- and inorganic-free blank water was passed through all sample collection processing devices and treated as a regular flow-weighted composite sample. All constituent concentrations analyzed for in the equipment blank were less than the detection limit, except for the chemical oxygen demand [96 mg/L (milligrams per liter)], dissolved calcium (0.03 mg/L), dissolved phosphorus (0.03 mg/L), total ammonia as nitrogen (0.12 mg/L), suspended solids at 105 °C (5 mg/L), total organic carbon (27 mg/L), chromium [3 jog/L (micrograms per liter)], and methylene chloride (0.03 mg/L). The cleaning procedure used for equipment, rinsing with methanol, probably resulted in the large chemical oxygen demand and total organic carbon concentrations. On recognition of the data anomalies, the cleaning procedure was modified to exclude the use of methanol.
A trip blank was analyzed for volatile organic compounds to determine if diffusion of these compounds occurred through the septum caps during shipping and storage. A trip blank is a sample of organic-free water filled and shipped with the empty sample collection bottles and taken to the study sites with the collection bottles, never opened onsite, and returned to the laboratory with the samples. One trip blank was analyzed for samples collected at site 3 on July 9, 1992. All constituents were less than the detection limits, except for methylene chloride, which had a concentration of 0.5 ug/L (detection limit was 0.2
Analysis of replicate samples was used to assess the precision of sample collection from sample splitters, shipping and storage, and laboratory analyses (M.W. Sandstrom, U.S. Geological Survey, written commun., 1990). Replicate samples for inorganic analyses were split from a flow-weighted-composite sample using a churn splitter. The data for the inorganic replicate samples are listed in table 4, at the back of this report.
Matrix spiked sample sets were analyzed to determine analytical recoveries for the different conditions that a sample undergoes. Matrix spiked sample sets for pesticides and acidic, basic, and neutral organic compounds included two replicate field spiked samples, a replicate laboratory spiked sample, and a replicate unspiked sample. A matrix spiked sample set for volatile organic compounds
included a replicate laboratory spiked sample and a replicate unspiked sample. All samples were split from a flow-weighted composite sample using a cone splitter and spiked with a selected set of analytes of known concentrations onsite for replicate field spiked samples and at the laboratory for laboratory spiked samples. Comparison of the two replicate field spiked samples was used to assess the precision of the sample collection from the cone splitter, shipping and storage conditions, and laboratory analyses. Degradation during shipping also can be assessed from the results of a replicate laboratory spiked sample and a replicate field spiked sample. The replicate unspiked sample is analyzed to determine the ambient constituent concentrations. If a constituent is detected in the unspiked sample, the concentration is then subtracted from the constituent concentration determined in the other three replicate spiked samples to compute the percent recoveries. Concentrations and percent recoveries for the matrix spiked sample sets for pesticides are listed in tables 5 and 6, at the back of this report. Results for the matrix spiked sample sets for acidic, basic, and neutral organic compounds are listed in table 7, at the back of this report, and results for the matrix spiked sample sets for volatile organic compounds are listed in table 8, at the back of this report.
BASE-FLOW DATA
A total of 226 samples were collected at 193 sites (fig. 2). Some sites were sampled more than once because concentrations of selected constit uents were previously detected in a sample or were expected to be present from certain land uses. For each sample, discharge, specific conductance, pH, water temperature, total chlorine, total copper, total detergents, and total phenols were determined. A summary of the results is listed in table 9, at the back of this report. The maximum discharge, 10.1 ft3/s (cubic feet per second), was measured near the mouth of Rock Creek (fig. 2). The pH of five samples exceeded 9.0 and these samples had a range of discharge from 0.003 to 0.15 fr/s and a range of specific conductance from 507 to 773 US/cm (microsiemens per centimeter at 25 °C). Total chlorine was detected 45 times at 39 sites,
12
with a maximum concentration of 0.9 mg/ L. Total copper and total phenols were not detected at any of the sites. Total detergents were detected at site S19 (fig. 2) with a concentration of 0.3 mg/L at a discharge of 0.02 ft3/s. The results for the base- flow samples are listed in table 10, at the back of this report.
Stormwater-Runoff Sampling Data
The following sections contain data from stormwater-runoff sample collection at sites 1 to 5 from July 9,1992, through February 11,1993. These sections discuss rainfall, bacteria, inorganic and organic compound concentrations, and observed and simulated loads.
Rainfall and Discharge Characteristics
The rainfall and discharge characteristics for the storms sampled from sites 1 to 5 are listed in table 11, at the back of this report. Rainfall inten sities and discharge hydrographs of the storms sampled are shown in figures 3 to 7. All of the storms sampled had more than 0.10 in. rainfall. At the time of sampling there had been less than 0.10 in. of rainfall in the 72 hours preceding the storm, except for the stormwater runoff sampled at site 3 beginning on July 9,1992 (which had 0.10 in. of rainfall). The rainfall depths for the storms sampled ranged from 0.22 to 0.98 in. Rainfall depths for the storms at site 3 on July 9 to 10,1992, were collected from the rain gage at site RN1 and the depth at site 2 on July 22,1992, was collected from an onsite non-recording rain gage, because of equipment malfunction at rain gage RN2 at the time of the storms. Rainfall durations ranged from 20 to 324 minutes. The storm sampled at sites 1 and 4 on February 11,1993, was preceded by 9 in. of snow that had almost melted at the time of the storm. The percentage of discharge from precipi tation during sampled storms ranged from 6 percent at site 1 to 66 percent at site 3.
Bacteria
Analyses of bacteria from sites 1 to 5 are listed in table 12, at the back of this report. Fecal coliform ranged from 500 col/100 mL (colonies per 100 milliliters) at site 4 to 290,000 col/100 mL at site 1; 14 of 35 estimated colony counts at all sites were based on non-ideal colony counts. Fecal streptococci ranged from 1,900 col/100 mL at site 2 to 500,000 col/100 mL at site 1; 8 of 35 estimated colony counts at all sites were based on non-ideal colony counts. A fecal coliform to fecal strepto cocci ratio of 4.0 or more indicates human wastes and a ratio of 0.7 or less indicates animal waste (Henry and Heinke, 1989). The ratio from 35 bacteria samples averaged 0.9. The minimum fecal coliform to fecal streptococci ratio was 0.01 at site 5, and the maximum fecal coliform to fecal strepto cocci ratio was 4.1 at site 5. The discharge at the time of bacteria sample collection ranged from 0.31 ft3/s at site 5 to 260 ft3/s at site 3.
Constituent Concentrations
For the first-flush samples total chlorine concentrations ranged from less than 0.1 to 0.2 mg/L with two detections from seven samples (table 12). Total cyanide was not detected in 13 first-flush samples. Total phenols ranged from less than 1 to 7 jjg/L for 13 samples with 12 detections. Total oil and grease ranged from less than 1 to 16 jig/L for 13 samples with 8 detections. Discharge at the time of sample collection for the first-flush samples ranged from 0.40 ft3/s at site 5 to 260 ft3/s at site 3.
The values of selected physical properties and constituent concentrations of the flow-weighted composite samples are listed in table 13, at the back of this report. Specific conductance ranged from 68 nS/cm at site 3 to 26,500 ^S/cm at site 5. The chemical oxygen demand for all sites ranged from 36 jig/L to 1,600 ng/L at site 3. The biochemical oxygen demand ranged from 13 mg/L at site 3 to greater than 650 mg/L at site 1. Dissolved solids

concentrations ranged from 34 mg/L at site 3 to 14,700 mg/L at site 5. The site 5 basin includes large unsheltered piles of road salt. Total suspended solids concentrations ranged from 38 mg/L at site 3 to 1,200 mg/L at site 5. Nitrite plus nitrate as nitrogen concentrations ranged from less than 0.05 mg/L at site 1 to 1.5 mg/L at site 4. Total ammonia as nitrogen concentrations ranged from less than 0.01 mg/L at site 1 to 1.0 mg/L at site 3. Mean total ammonia plus organic nitrogen as nitrogen concen trations ranged from 0.2 mg/L at site 5 to 3.3 mg/L at site 1. Mean total phosphorus concentrations ranged from 0.12 mg/L at site 5 to 1.3 mg/L at site 1 and dissolved phosphorus concentrations ranged from less than 0.01 mg/L at sites 1 and 5 to 0.42 mg/L at site 3. Mean total organic carbon concen trations ranged from 12 to 410 mg/L at site 3. Total cyanide concentrations were detected twice at the detection limit of 0.01 mg/L at site 5.
Trace Elements
The sources of trace elements in streams are associated with both natural occurring chemical weathering and human activities (Viessman and Hammer, 1985). Concentrations for the whole- water recoverable trace element analyses for the flow-weighted composite samples are presented in table 14, at the back of this report. Antimony, beryllium, selenium, and thallium were not detected. The mercury concentration was 0.2 ug/L at site 4 and 0.1 and 0.3 ug/L at site 5. The following trace elements were detected (concentra tions are listed in parentheses): arsenic (1 to 10 ug/L), cadmium (less than 1 to 40 ug/L), chromium (less than 1 to 99 ug/L), copper (8 to 130 ug/L), lead (20 to 800 ug/L), nickel (3 to 37 ug/L), and zinc (110 to 6,200 ug/L). The largest concentrations of arsenic and chromium occurred at site 1. The largest mean concentrations of cadmium, lead, mercury, nickel, and zinc occurred at site 5. The only detection of silver was at site 4 with a concentration of 12 ug/L.
Pesticides
The results of the whole-water recoverable analyses for the pesticides from the flow-weighted composite samples are presented in table 15, at the back of this report. The concentrations are compared to Missouri water-quality criteria for human health protection-fish consumption (Missouri Department of Natural Resources, 1991b). Chlordane concentrations of 0.1,0.2, and 0.4 ug/L at site 1 and two detections of 0.1 ug/L at site 2 exceeded the water-quality criteria of 0.00048 ug/L. At site 1, cis-chlordane and trans- chlordane had concentrations of 0.1 ug/L. At site 4, concentrations ofp,p'-DDD andp,p'-DDT were at the detection limit of 0.1 ug/L, which exceeded the water-quality criteria of 0.00024 ug/L. Concentrations of diazinon were 0.2 and 1.0 ug/L at site 1; concentrations of 0.1 ug/L were detected twice at site 2; concentrations of 0.2 and 0.1 ug/L were detected at site 3; and a concen tration of 0.2 ug/L was detected at site 4. A dieldrin concentration of 0.05 ug/L at site 1 exceeded the water-quality criteria of 0.000076 ug/L. Lindane was detected at the detection limit of 0.03 ug/L at site 4. The polychlorinated biphenyl Aroclor 1248 concentration of 2.4 ug/L at site 4 exceeded the water-quality criteria of 0.000045 ug/L.
Volatile Organic Compounds
Of the 63 volatile organic compounds analyzed, 13 compounds were detected a total of 27 times. The results of the whole-water recov erable analyses of the flow-weighted composite samples from sites 1 to 5 are listed in table 16, at the back of this report. The concentrations of volatile organic compounds ranged from 0.2 to 5.1 ug/L. Naphthalene was detected with the largest concentration of 5.1 ug/L at site 2 and was detected a total of five times at sites 1, 2, 3, and 4. Ten compounds were detected at site 2, and nine of the
19
detections were from the same flow-weighted composite sample. Site 3 had eight detections of volatile organic compounds. The following compounds were detected at sites 1 to 5 during this study: benzene; n-butylbenzene; dichlorodifluo- romethane; ethylbenzene; /Msopropyltolune; 1,3,5-trimethylbenzene (mesitylene); dichlo- romethane (methylene chloride); naphthalene; n- propylbenzene; 1,2,4-trimethylbenzene (pseudoc- umene); styrene; toluene; and xylene. Concentra tions of volatile organic compounds detected did not exceed any of the listed water-quality criteria for human health protection-fish consumption (Missouri Department of Natural Resources, 1992).
Acidic, Basic, and Neutral Semi-Volatile Organic Compounds
The results of the whole-water recoverable analyses for the acidic, basic, and neutral semi- volatile organic compounds from the composite samples are presented in table 17, at the back of this report. Concentrations of these compounds were compared to Missouri water-quality criteria for human health protection-fish consumption (Missouri Department of Natural Resources, 1992). Concentrations of di-2-ethylhexyl phthalate were 6.0 jig/L at site 1; 6,7, and 8 jig/L at site 2; and 10 |Ag/L at site 3, and all concentra tions exceeded the water-quality criteria of 5.9 |Ag/L. A concentration of di-2-ethylhexyl phthalate was at the detection limit of 5 ng/L at site 5. Di-2- ethylhexyl phthalate is one of the most widely used plasticizers (Smith and others, 1988). Concentra tions of fluoranthene were 18 |Ag/L at site 1,15 |ig/L at site 4, and 10 |ig/L at site 5. Concentra tions of phenanthrene were 7 |ig/L at sites 1 and 4, and 6 |Ag/L at site 5. Concentrations of pyrene were 13 jig/L at site 1,11 jig/L at site 4, and 7 jig/L at site 5. The detections of fluoranthene, phenan threne, and pyrene occurred in the same flow- weighted-composite sample for each site. Fluoran
thene, phenanthrene, and pyrene, classified as polycyclic aromatic hydrocarbons, can originate in surface water from atmospheric deposition, surface runoff, and industrial and municipal wastewater effluents (Smith and others, 1988).
Volume and Loads
The observed volume in cubic feet and loads in pounds for each site for every constituent with at least one detection and simulations for storm volume and loads calculated with the Driver and Tasker (1990) equations are listed in tables 18 to 22, at the back of this report. The observed and simulated volume and loads were compared to the second storm sampled at each site using the following equation:
Simulated value - Observed value Observed value
x 100 = percent difference (2)
For the storms sampled on October 7,1992, at site 1, chemical oxygen demand, total phosphorus, copper, and zinc loads had less than a 50 percent difference between the observed and the simulated values. For the storms sampled on September 7, 1992, at site 2, dissolved solids and dissolved phosphorus loads had less than a 50 percent difference between observed and simulated values. For the storms sampled at site 3 on August 18, 1992, volume, chemical oxygen demand, total ammonia plus organic nitrogen, total nitrogen, total phosphorus, cadmium, and zinc loads had a 50 percent or less difference between the observed and simulated values. For the storm sampled on September 26, 1992, at site 4, the difference between the simulated volume and all the simulated loads and the observed volume and loads was greater than 60 percent. For the storm sampled at site 5 on October 7,1992, the simulated and observed loads were less than 50 percent for chemical oxygen demand, suspended solids, and lead.
