Short Description

A Class II Inspection was conducted at the town of Sumas Wastewater Treatment Plant on September 23-25, 1991. The inspection found a plant which was performing quite well, achieving 98 percent removal of BOD5 and TSS, as well as nitrification and denitrification. Copper, lead, and zinc were detected, but at concentrations below water quality standards. No toxicity was indicated by bioassays run on effluent. The present sampling procedure involving 8-hour hand composites is not always producing representative samples, and should be replaced.
