Current Topics of Regulatory Interest and Services



The USEPA's revised Lead and Copper Rule for drinking water became effective on December 16, 2021, with compliance for most parts by October 16, 2024.

The revised rule is complicated, but one of the straightforward requirements is the identification of all lead service lines which connect drinking water mains to buildings, about 10 million lead service lines across the U.S. in total.  New technology will be helpful for this step in the process.  (See Drinking Water on the Areas of Expertise page.)

USEPA also announced on December 16, 2021 allocations for 2022 from the Federal infrastucture bill and other funding sources for replacing lead service lines, and for clarifying the revised Lead and Copper Rule before the 2024 compliance date.

California Proposition 65 is a consumer labeling law.

OEHHA, the California agency that oversees Proposition 65, has added a website (linked to the Prop 65 website) to help explain Prop 65 warning requirements.  It's searchable by chemical and by application.

There are over 900 substances on the Prop 65 list, and OEHHA periodically adds more chemicals to the list based on concerns for cancer or reproductive toxicity, which are now part of labeling requirements.
