Monitoring Waivers under the Lead and Copper Rule Revisions for Systems Serving 3,300 or Fewer People

This guidance provides information on monitoring waivers for PWSs that serve 3,300 or fewer people. These PWSs must have low lead and/or copper 90th percentile levels and meet plumbing material restrictions.

Simultaneous Compliance Guidance Manual for Stage 2 Rules

This manual discusses the issues that PWSs face as they implement changes to comply with the Stage 2 DBPR and LT2ESWTR while still being required to comply with earlier rules such as the Total Coliform Rule/Revised Total Coliform Rule and the Lead and Copper Rule.

Some of the changes may have compliance or operational consequences if not properly designed, implemented, and monitored.

Effect of pH, DIC, Orthophosphate and Sulfate on Drinking Water Cuprosolvency

Field data from various copper monitoring studies and LCR compliance data are often inappropriate. They are misleading for reliably of determining fundamental chemical relationships behind copper corrosion control.

To address this deficiency, a comprehensive solubility model for copper in drinking water has been developed. It is qualitatively and quantitatively consistent with available data for copper dissolution and precipitation.
