California's DTSC outlines protocols for testing lead content in plumbing materials

For many years, Proposition 65 plaintiffs and the California Attorney General filed a lot of cases against manufacturers of plumbing fixtures because (a) the lead contained in various components leached into the water passing through, and (b) as noted in prior posts, the lead standard under Prop. 65 is very, very strict (the concentration needed to show a violation of the lead standard as a reproductive toxicant was quite small).  Eventually, AB 1953 [http://www.leginfo.ca.gov/pub/05-06/bill/asm/ab_1951-2000/ab_1953_bill_20060930_chaptered.html] became law in 2006 and SB 1334 [http://www.leginfo.ca.gov/pub/07-08/bill/sen/sb_1301-1350/sb_1334_bill_20080929_chaptered.html] in 2008; both created a so-called "lead free" standard for plumbing materials effective 1/1/10.  ["Lead free" of course does not mean lead free.  Fixtures conveying drinking water were limited to 0.25% weighted average lead content.]
The Department of Toxic Substances Control is required to select up to 75 fixtures annually and test them for compliance.  DTSC has now issued a Fact Sheet outlining its test protocols.  See http://www.dtsc.ca.gov/PollutionPrevention/upload/lead-in-plumbing-testing-protocol.pdf.
