The wastewater treatment plant laboratory is approved by the New York State Department of Health Environmental Laboratory Approval Program (ELAP) to perform analysis on non-potable water. In addition to being certified for the analysis of conventional analytes such as solids, biochemical oxygen demand (BOD) and nutrients. The lab is also certified to analyze nine metals by both Flame and Graphite Furnace Atomic Absorption (AA) techniques. Samples of wastewater and biosolids collected within the plant are analyzed for compliance with SPDES limits as well as for process control. Samples collected from industrial dischargers within the collection system are analyzed in accordance with federal, state, and local pretreatment standards. The laboratory also performs analysis of industrial Biochemical Oxygen Demand (BOD), Total Suspended Solids (TSS), and Total Kjeldahl Nitrogen (TKN) to determine industrial sewer billing.
