Lead and Copper Rule (LCR) Revisions – NRWA is participating on an EPA consultation panel considering revisions to the LCR.  Last week, during a webinar EPA made the following findings on the current rule:

  • Sampling sites that have the greatest copper levels almost always are different from the sites that have the most lead (38:30)
  • Current sampling sites for copper are flawed (46:00)
  • First litre sampling for lead is not capturing lead contributed by LSL (46:20)
  • People are getting sick from copper where the utility is in compliance with the copper action level (47:20)
  • Interior plumbing, especially galvanized pipe, will accumulate lead like a sponge (56:17).
  • Without tailoring the monitoring to each specific house it is easy to intentionally miss capturing the peak lead levels for that sampling site (1:00:50).
  • To target high lead levels, the following need to be included in sampling site selection: water quality zones, length of LSLs & PLSLs, physical disturbances, unstable surface coatings, etc. (1:03:50).
