How often is a local water system tested to ensure it complies with the standards?
PWSs must test all sources of water on a regular basis. Most systems test for over 80 contaminants as scheduled by MassDEP. The schedule depends on past testing results and the federal requirements. If a system detects a contaminant above the MCL, additional monitoring and testing is required. MassDEP regional offices inspect these systems on a regular basis and ensure that systems comply with the testing and notification requirements.
