ResumoStormwater discharges from the San Isidro Industrial Park, Canovanas, Puerto Rico, were investigated in 1993 and 1994 by measuring the flow rate and collecting samples at three separate outfalls.The drainage areas for each outfall were delineated and estimated.The flow rate was used to calculate the volume of the discharges.The collected samples were analyzed to determine the quality of the discharges.Constituent mass and mass per area were estimated for each outfall.The average concentrations of oil and grease, biochemical oxygen demand, and total phosphorous from all the samples collected were below the U.S. Environmental Protection Agency Stormwater benchmark concentrations.Average concentrations of chemical oxygen demand, total suspended solids, and nitrate plus nitrite exceeded the benchmark concentrations in some of the sampled drainage areas.
