McCracken, R. AND L. Shepard. ANALYSIS OF ACID PRECIPITATION SAMPLES COLLECTED BY STATE AGENCIES: JANUARY 1987 - DECEMBER 1987. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/3-89/018.
Description:
The report presents the analytical data from the 31 acid precipitation collection sites in the State Operated Network. Samples are collected weekly in plastic bag liners and shipped in 500 mL polyethylene bottles to Global Geochemistry Corp. (the central laboratory for the network). The report contains maps showing the location of each site, plots of analytical data, tables of all field and analytical data, plots comparing field and laboratory pH and conductivity, and information on data quality. Samples are analyzed for pH, strong acid, conductivity, fluoride, chloride, nitrite, phosphate, bromide, nitrate, sulfate, ammonium, sodium, potassium, calcium and magnesium. The central laboratory renders technical assistance to the collection sites on problems concerning pH and conductivity. Each of the 11 participating state agencies receives analytical reports for the samples analyzed the previous month. Analyte concentration data are sent to the Acid Deposition System (ADS) for inclusion in the national acid precipitation data base.
