Lead and Copper Rule Materials Inventory Depot

In the early 1990’s, community and non-transient non-community water systems were required to complete a materials evaluation of their distribution system in order to identify a pool of targeted sampling sites to be used in the water system’s lead and copper sampling plan (40 CFR §141.86(a) and LAC 51:XII.1703).

The intent of the materials evaluation was to identify high-risk locations by determining the materials of construction present in the water system’s distribution system including the piping, solder, caulking, and interior lining of distribution mains, alloys and home plumbing.  In addition, the materials evaluation was required to include locations served by a lead service line and/or other lead plumbing served by the water system.

The United States Environmental Protection Agency (USEPA) has requested States to work with their public water systems to improve transparency regarding the implementation of the Lead and Copper Rule (LCR).  On July 11, 2016, LDH sent out a memo to all large public water systems (those serving more than 50,000 persons) requiring them to submit a materials inventory of their distribution system; including locations of lead services lines, together with any updates to the inventory and map(s) of lead service lines and lead plumbing in the system if present.

The following table summarizes the submittals we have received from each water system.   This site will continue to be updated as new information is received.  If you have a specific question pertaining to the materials of your service line or plumbing please contact your water system directly.

Contact local plumbing/building department for records that may indicate the dates of construction and plumbing materials installed within publicly and privately owned structures.  Note that the Safe Drinking Water Act (SDWA) lead ban requiring the use of “lead-free” plumbing for drinking water took effect in Louisiana in 1988. Buildings constructed after this date would not legally contain lead solder and it required pipes, fittings and fixtures to contain no more than 8.0 percent lead. Also, Louisiana Act 362, which became effective January 1, 2013, further reduced the lead content of pipes, fittings and fixtures from not more than 8.0 percent lead to not more than a weighted average of 0.25 percent lead.
