Lead and Copper Rule Revisions
The Lead and Copper Rule Revisions (LCRR) represent a major change in drinking water regulations impacting all 60,000+ public water systems in the U.S. All water systems will be required to develop a lead service line (LSL) inventory, strengthen treatment to comply with a new 10 microgram per liter (μg/L) trigger level, sample schools and childcare facilities, and enhance public communications. Furthermore, systems with LSLs will need to develop a replacement program depending on lead compliance sample concentrations. Read on to learn about the changes that will take effect and the systems that will be impacted.
- Identifying the areas most impacted
- Strengthening drinking water treatment requirements
- Replacing lead service lines
- Increasing sampling reliability
- Improving risk communication
- Protecting children in schools and childcare facilities
Begin preparations as soon as possible
All systems need to provide the following materials by October 16, 2024.
LSL inventories will take time to prepare.
A combination of approaches will likely be needed to develop a defensible inventory.
Research records and historic construction practices
Apply GIS-based tools
Analyze water quality results and profiling
Visually inspect pipe materials/excavating
Carollo can help you determine how your system will be impacted and work with you to develop and implement a compliance plan.
We can support you in the following ways:
- Navigating the intricacies of the 115-page rule.
- Identifying a LCRR Compliance Strategy that is specific to your utility.
- Digitization of records, integration into GIS, and other digital solutions.
- Reviewing changes in water quality or treatment that could impact future compliance.
- Conducting desktop, bench, or pipe loop corrosion control testing to meet compliance requirements and identify treatment to achieve lower lead concentrations.
- Assisting with compliance with the current LCR.
- Corrosion control study.
- Evaluating and addressing the impact of source water or treatment changes.
- Developing optimized water quality parameters (OWQPs).
Need to conduct a corrosion control study?
Carollo can help you identify the optimal testing approach, conducting either a desktop comparison of an analogous system, coupons tests, recirculating pipe loops, or a flow through pipe rig.
