Lead & Copper

Lead Service line Inventory

The Lead and Copper Rule was created by U.S. EPA to control the corrosivity of water, while also protecting public health. Lead and copper enter drinking water from the corrosion of lead and copper containing plumbing materials including home interior plumbing and water service lines. Water systems are required to collect tap samples within their water distribution systems using risk-based tiering criteria, with the highest priority being sites that have plumbing materials containing lead. The rule establishes action levels for lead and copper based on a 90th percentile level of tap water samples. An exceedance of one or both action levels trigger additional actions by the water supply. All Community and Non-Transient Non-Community Public Water Systems are subject to the lead and copper rule requirements.

Lead and Copper Rule Revisions (LCRR) and Lead and Copper Rule Improvements (LCRI)

In 2019, U.S. EPA proposed lead and copper rule revisions (LCRR). These rules became final on Dec. 16, 2021. On the same date, U.S. EPA announced the development of a new regulation, lead and copper rule improvements (LCRI). It is important to note, that while U.S. EPA is drafting the LCRI and has indicated intent to modify certain provisions of the LCRR, the service line inventory requirement stayed. This means that PWSs will need to submit a complete inventory to Ohio EPA by no later than Oct. 16, 2024.
