Description:
This report presents analytical data from the 30 acid precipitation collection sites in the State-Operated Network. amples are collected weekly in plastic bag liners and shipped in 500 mL polyethylene bottles to Global Geochemistry Corporation (the central laboratory for the network). his 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. amples are analyzed for pH, strong acid, conductivity, fluoride, chloride, nitrite, phosphate, bromide, nitrate, sulfate, ammonium, sodium, potassium, calcium, and magnesium. he central laboratory renders technical assistance to the collection sites on problems concerning pH and conductivity. ach of the 10 participating state agencies receives analytical reports for the samples analyzed the previous month. nalyte concentration data are put on tape for later inclusion in the Acid Deposition System (ADS) Data Base.
