Miscellaneous paperAbstract: A laboratory at the u. s. Army Engineer Waterways Experiment Station has been equipped with the proper apparatus, glassware, and chemicals so that water, soils, and sediments may be analyzed for pesticides, heavy metals, bacteria, biostimulants, and related constituents as needed in multiple samples. The setups are made based primarily on procedures recommended by the Water Quality Office and laboratories of the Environmental Protection Agency, Two gas chromatographs--one for use in analyzing chlorinated hydrocarbon pesticides and one for organophosphate pesticides--are available for pesticide analyses. Procedures and instrumental parameters of the chromatographs have been determined for up to 48 different chlorinated hydrocarbon and organophosphate pesticides. Capabilities have been established for analyzing routinely the following heavy metals: mercury, lead, zinc, cadmium, chromium, nickel, and copper. Bacteriological capabilities include analyses of water and sediments for total bacteria, total coliform, fecal coliform, and fecal strep. Additional equipment and supplies are needed for making biochemical oxygen demand determinations and for determining other parameters listed in Standard Methods of the American Public Health Association. In addition to the specific capabilities summarized above, this laboratory is equipped to routinely analyze multiple samples for pH; alkalinity; volatile, dissolved, and total solids; hardness; oil and grease; chemical oxygen demand; the following anions: chlorides, sulfates, biocarbonates, carbonates, and fluorides; the following biostimulants: ammonia, total Kjeldahl nitrogen, nitrite, nitrate, and phosphates; and the following dissolved metals: calcium, magnesium, iron ( ic), iron (ous), aluminum, manganese, sodium, potassium, and boron. A selected bibliography is included in this report.
