Modifications to the Lead and Copper Rule

The U.S. EPA is currently considering modifications to the Lead and Copper Rule. 

Should the new version of the rule change the status quo monitoring requirement where the water utility is responsible for complicated in-home compliance monitoring? 

What should a new monitoring protocol look like?

If you are in violation. Monitoring should involve two samples one first draw and one after a period of flushing to determine the source. If source water is the issue then by all means treat and take care of the problem. If found to be the homeowner then public education for all and for public housing /rental property lead abatement becomes mandatory.

If you are in violation of lead and or copper you should have to do additional monitoring, WQP and public education.  The way it reads now is “Public education is only required if Pb AL is exceeded”.  Copper can cause stomach and intestinal distress, liver or kidney damage and complications of Wilson’s disease in genetically predisposed people.  Why would you not do Public Education for Cu exceedance?  This rule is a TREATMENT TECHNIQUE rule, NOT a lead line replacement rule.  If your water is corrosive it will not only leach the Pb out of the pipes but also Cu and slowly deteriorate your entire system and the plumbing in homes and businesses.   We are getting caught up in the Flint case, which is a terrible thing, and should have never happened.  The lead and copper results for Flint, when they were on the Detroit water, passed the testing.  It was only when they changed water sources, and the water was deemed corrosive, is when Flint started to have problems. Even GM in Flint quit using the water at their factories due to the corrosiveness.  Again, use the current rule as it was intended, it is a treatment technique rule. Non-corrosive water = no problem, Corrosive water = problems within your entire system.  

Replacing all the lead lines and keeping the water corrosive does nothing for the copper issues and the issues of corrosiveness within your entire system.  Make your water non-corrosive through the Treatment Technique requirements and do the WQP sampling as required by the current rule.  Educate the public that just replacing the lead lines doesn’t fix the problem.  Making the water non-corrosive does fix the problem.
