A. PURPOSE AND APPLICABILITY

The purpose of this Standard Operation Procedure (SOP) is to establish a uniform procedure for collecting wastewater samples for the analysis of non-organic parameters specified in National Pollutant Discharge Elimination System (NPDES) permits and in pretreatment agreements. The procedures outlined in this SOP are applicable to all Regional inspectors who collect samples of wastewater at federal, municipal and industrial facilities in support of water compliance regulations.

B. SUMMARY OF THE METHOD

Compliance samples of a wastewater stream are collected in accordance with permit requirements. They can be instantaneous (grab) samples, and/or composites. A composite sample is a sample in which, over a period of time, representative aliquots of a wastewater stream are collected manually or automatically using a portable compositor. Normally, the aliquots are combined into one sample in the compositor. At the end of sampling, the sample is divided among one or more containers and preserved, if needed. The sample is then packed in ice and shipped to the EPA Region 21’s Laboratory (RLAB). The resultant data are then compared to permit limits to determine compliance or are used to establish new permit limits.
