EPA’s Office of Research and Development (ORD) and Office of Water invite you to a free webinar: Reduction of Lead in Drinking Water.
Identifying and solving lead issues from water systems with materials/device replacement in drinking water system configurations; presented by Michael R. Shock from EPA ORD.
Identifying and assessing lead contamination and exposure potential in single-family residences is difficult enough, but doing the same kind of assessment and remediation in buildings, schools, and day care centers is even more challenging. It is of particular importance because of the absence of a threshold lead concentration for adverse health effects, as well as the elevated risk to infants and children. Wide variations of seasonal and diurnal water usage patterns, relatively low total water flow, and complex small-diameter piping networks having multiple lead-containing devices located in series in line and at multiple consumption endpoints, combine to make addressing lead contamination in building systems highly challenging. There is rarely, if ever, a “representative” sampling tap. The presentation reviews the nature of lead and copper occurrence and relationships to water quality and use, and then focuses on sampling strategies to identify and isolate the occurrence of leaded materials in building drinking water system configurations.
Tool for identifying drinking water system and plumbing products that meet the lead free requirement of the Safe Drinking Water Act; presented by Michelle L. Latham from EPA ORD.
In 2014, the definition of lead free in Section 1417 of the Safe Drinking Water Act (SDWA) was changed from not more than 8% lead content to not more than a weighted average of 0.25% lead with respect to the wetted surfaces of pipes, pipe fittings, plumbing fittings, and plumbing fixtures. Although there is no mandatory federal requirement for lead free product testing or third-party certification under the SDWA, as of December 2015, consumers can increase their level of confidence by purchasing products that have been certified as meeting the SDWA lead free requirement. Because there is not a single, uniform mark for identifying certification to lead content, it can be difficult to determine if a product is lead free. This presentation will highlight a tool designed to help consumers identify lead free drinking water system and plumbing products that have undergone third-party certification testing.
A certificate for one continuing education contact hour will be offered for this webinar.
