Abstract

Lead (Pb) in public tap water is a national health concern and is the main pathway of human exposure to Pb. The City of Dayton has verified Pb pipelines and homes with Pb plumbing; thus, residents are at risk to Pb leaching into their tap water. I sampled water from 130 residential and 24 public water taps and measured Pb and copper (Cu). Five percent of samples exceeded the action level for Pb (> 15 [micro]g/L) and none exceeded the action level for Cu. The City of Dayton's lead pipeline map identifies potential Pb exposure from Pb distribution pipes. However, the samples that exceeded Pb action level were from the first draw, indicating Pb-bearing plumbing and fixtures within Dayton homes drives Pb concentrations in my dataset. Most of the samples that exceeded action level were from homes assessed below Dayton's median household value and built before 1986.
