ABSTRACT

All studies included in this book investigated pesticide occurrence in one or more water column matrix (water, suspended solids, surface microlayer, and dissolved organic carbon). Studies reviewed are summarized in Tables 2.1, 2.2, and 2.3 (located at end of chapter), according to three main categories: (1) national and multistate monitoring studies, (2) state and local monitoring studies, and (3) process and matrix distribution studies. National and multistate monitoring studies reviewed

FWQA study (then called Public Health Service). Synoptic survey of rivers throughout the United States. One sample taken at each site in September 1964 during low flow. Compounds estimated to constitute >60 percent of chlorinated pesticide use at the time. Data are analyzed in terms of geographic distribution. Generally, higher levels of chlorinated pesticides were observed in the North Atlantic, lower Mississippi, and California basins.

FWQA study (then called Federal Water Pollution Control Administration). Synoptic survey of rivers throughout the United States in 1965, and summary of data from previous sampling, 1957–65. Concentration data and detection frequency shown for 1965 survey. One sample taken at each site in September 1965 during low flow. Compounds constituted >60 percent of chlorinated pesticide use. Endrin and dieldrm detections decreased from 1964 synoptic survey. DDT group essentially unchanged. Endrin occurrence in lower Mississippi declined after reaching maximum in autumn of 1963.

FWQA study (then called Federal Water Pollution Control Administration). Synoptic survey of rivers throughout the United States. One sample taken at each site in September 1966 during low flow. Compounds constituted >60 percent of chlorinated pesticide use. Dieldrin continues to dominate detections. Endrin levels decreased from 1964 synoptic survey, but increased slightly from 1965 survey. Heptachlor detections down significantly from 1965 survey. Detections most common in the Northeast and Mississippi River Valley. Evidence that impoundments result in lower levels of organo-chlorines in downstream waters because of sedimentation.

Detection frequencies shown are for raw river water. Detection frequency in finished water samples was zero for toxaphene and methoxychlor; 10 to 25 percent for aldrin, endrin, chlordane, DDE, and DDT; and 40 to 75 percent for dieldrin and the HCHs.

Seston contained traces of dieldrin at 24 of 31 sites and DDE at 12 of 33 sites. Traces of dieldrin, and measurable amounts of DDD, DDE, and DDT were detected in sediments at 1 to 13 sites. None of the organophosphorus compounds were detected in any of the media.

USGS nationwide study of pesticides in major rivers of the United States. Water sampled four times per year and bed sediments two times per year. Less than 10 percent of samples contained detectable levels of any of the analytes. This was partly due to high detection limits in this study. Much lower detection frequencies than in the 1968–71 study (Schulze and others, 1973). Gradual decline in occurrence of organochlorines evident. No clear trends for herbicides or organophosphate insecticides observed.

Retrieval of data on concentrations of priority pollutants in ambient waters from USEPA’s STOrage and RETrieval water quality database (STORET) for the years 1975–82. Note that median concentrations are shown, not maximum. Data must be viewed with caution, as samples are not necessarily representative of ambient conditions across the entire United States and seasonality is not taken into account. Levels in biota, sediments, and effluents also are discussed.

Atrazine load entering Gulf of Mexico estimated as 0.4 percent of amount applied in basin in 1987 and 1.7 percent applied in 1989. Load estimates indicate a point source of alachlor, 2,6-diethylaniline, and the acetanilides near St. Louis, Missouri; <0.5 percent of total detected in suspended solids. Cross channel mixing downstream from river confluences shown to be slow, implying that samples must be representative of entire river width. Concentration data shown are for the 5/88 to 6/88 sampling trip only.

Duration of monitoring was 1 to 2 years at all sites. Data from 1975–76, 1985–87, or 1990–91, depending on site. Concentration data shown are from all sites and samples. Time-weighted annual means were below 3 μg/L at 94 percent of sites. Eighty-nine percent of individual samples were below 3 μg/L. Maximum concentrations occurred in June (41 percent), May (28 percent), or July (13 percent).

Three sets of concentration data shown are for the three rivers. Annual mean concentrations for Mississippi River sites ranged from 0.26 to 2.2 μg/L. Annual mean concentrations for Missouri River sites ranged from 0.5 to 3.77 μg/L. Annual mean concentrations for Ohio River sites ranged from 0.38 to 0.84 μg/L.

USGS study of occurrence of herbicides and degradation products in reservoirs throughout the midwestem United States. Seventy-six reservoirs sampled bimonthly from 4/92 to 3/93. Data reported are preliminary results for 4/92 to 11/92. Results indicate that a number of these compounds are present at higher concentrations in reservoirs than in streams at certain times of the year. The ESA metabolite of alachlor appears to be relatively stable in the reservoirs. Concentration data shown are approximate.

Samples were collected on three sampling cruises. Concentration and detection frequency data shown are from the July-August 1991 cruise. Analytes included pesticides used on major crops (com/soybean, rice, cotton, forestry) grown in different regions of the basin and several degradation products. Loads from tributaries and in the Mississippi River estimated for a number of the pesticides. Ratios of parent and degradation product concentrations imply that alluvial aquifers serve as storage areas and sources to the rivers.

Samples collected every 2 weeks to quantify inputs of organochlorines to Lake Ontario from Niagara River. Concentrations on suspended sediment varied with season. Total DDT highest in May and June. Much of the mirex, DDT, and PCBs associated with suspended sediment appears to emanate from sources between Grand Island and Lake Ontario, rather than from Lake Erie. Concentrations (in micrograms per kilogram) are based on dry weight of sediment.

Great Lakes:

Water

(means)

Organochlorine pesticide (and PCB) concentrations were measured in water and suspended sediments at Niagara-on-the-Lake (Lake Ontario end of Niagara River). Loading estimates indicate that suspended sediments were responsible for ∼40 percent of the loading to Lake Ontario of PCBs, DDT, and HCB, and considerably less for other organochlorines. Comparisons of suspended sediment concentrations with bed sediment concentrations in Lake Erie indicate that Lake Erie was not the major source of PCBs, mirex, and chlorobenzenes to Lake Ontario and that these compounds entered the system along the Niagara River. Detection limits inferred from data.
