To inform the public.
Description:
In order to remain compliant with the U.S. EPA’s Lead and Copper rule, it is pivotal to understand the relationship between factors affecting lead release in drinking water distribution systems. Lead solids were synthesized in cell experiments using a pH range of 6-11 with both 10 and 50 mg C/L. The mineralogy of the lead synthesized was impacted by the pH as well as the dissolved carbon concentrations. However, time (age) had little to no impact on the formation of either cerussite or hydrocerussite. These findings help function as a baseline for comparison of different drinking water treatment options.
