Priority pollutant analysis is required for many permit renewals for wastewater treatment facilities. Priority pollutant scans, along with sludge samples, are conducted on wastewater treatment plant effluents. A priority pollutant scan is an analytical battery of parameters conducted to characterize a matrix for contaminants. If contaminants are detected, this information is used to determine if corrective action needs to be taken to eliminate the contaminate source.
Regulatory requirements may force a permittee to conduct further monitoring and evaluations.
