The report summarizes the analytical results from 30 state operated wet acid deposition sites. All sites submitted their samples to the same laboratory so that comparisons of data could be made from different geographic areas. The use of a central laboratory also provided cost efficiencies and improved documentation of data quality. The report contains maps showing the location of each site, plots of analytical data during the time period, tables of all field and analytical data, a table comparing the concentration of each analyte at the different sites, a table of precipitation weighted data for each site, plots comparing field and laboratory pH and conductivity measurements, and quality control tables and plots giving information on overall data quality.
