Pb in U.S. Drinking Water #lead #cleanwater


I read this morning in the Washington Post that the US EPA is just weeks away from putting out new rules on how to test for Pb in drinking water. Presumably that will make more water utilities install better heavy metal removal systems. I hope companies who have followed the research on Pb removal with biochar are prepared to roll out cost-competitive products for this. Appropriately functionalized biochar has been shown to be a good Pb filter.
