| Short Description |
The Washington State Department of Ecology conducted a Class II Inspection at the Maple Lane School Wastewater Treatment Plant (WTP) on October 22-23, 1991. The objective was to chemically characterize WTP effluent by collecting two grab samples over a 24-hour period. Influent biochemical oxygen demand 5-day (BOD5) and total suspended solids results were much higher than typically found in untreated domestic wastewaters. The cause for the high variability might be attributed to: 1) the small population using the facility, and 2) high organic loading at the particular times the grab samples were taken. Arsenic, copper, mercury, and zinc were found in the wastewater. Four base neutral acid compounds and three volatile organic carbon compounds were also detected. | |||
