Frequent Questions

Are consecutive systems exempt from the requirements of the LT2 Rule?

Consecutive public water systems (PWSs) that purchase treated water from wholesale PWSs that fully comply with the monitoring and treatment requirements of the LT2 Rule are not required to take additional steps (e.g., conduct additional monitoring or install additional treatment) for that water under the rule (71 FR 654, 657; January 5, 2006).
