SB 595 New Hampshire Senate · 2026 Regular Session

relative to rulemaking for transient non-community water systems.

SB 595 creates a path for community water systems to return to standard testing schedules after being required to test more frequently due to missing or late water tests. It directly affects water systems sanctioned by the Department of Environmental Services for these violations. The key provision requires such systems to submit six consecutive timely water test results to revert to the original testing frequency. This bill modifies existing rules to provide a clear remediation process without changing overall testing requirements. The change applies only to systems that have corrected their testing compliance.
