ISet 1989 —— BOQCBOD —°— TSS Figure 1. Estimated statewide pollutant discharge loading (million kilograms) for analyzed major municipalities. Sixty-one facilities were included in the calculation of ammonia discharge trends. The estimated state- wide loading for these facilities was approximately million kilograms in 1987. This amount decreased 65% by 1992, to million kilograms. Sixty-one facilities were included in the calculation of chlorine residual trends. In 1987, the estimated statewide loading for these facilities was approxi- mately 145 thousand kilograms and, by 1992, discharges dropped by almost 25%, to 109 thousand kilograms (Figure 2)..
