Lead, unlike many other drinking water contaminants, is usually not present in the drinking water source, but rather results from the distribution system or on site plumbing itself.
It’s disappointing that EPA chose not to require full replacement of lead service lines — the largest source of lead in drinking water — and stopped short of other measures to reduce exposure.
Clean Water Action strongly supports Denver Water’s commitment to seek an alternative to orthophosphate that will achieve the same or greater reduction in lead exposure risk for its customers.
“EPA’s proposal lacks the most proactive step we can take to reduce lead at the tap - a timeline and a requirement for full lead service line replacement,” said Lynn Thorp, Clean Water Action National Campaigns Director. “There is a clear public health case and national momentum to get the lead out through a holistic and thorough plan to replace service lines.”
