Since the Flint, Michigan lead in drinking water case, communities all over the country have been taking a look into their public water supply. While the utility company can sometimes be responsible for lead in water from old water distribution lines that arrive to a building, other times it may be interior fixtures and other interior plumbing that is causing elevated lead levels in drinking water. In these examples, those interior sources of lead are not the responsibility of the public water supply company. The most recent community to make news is Chicago, Illinois where, in April, the Chicago Tribune reported that lead was found in tap water drawn from nearly 70% of 2,797 homes across Chicago within the past two years and that tap water in three of every 10 homes had lead concentrations above 5 parts per billion. The US Environmental Protection Agency has set its limit for lead in tap water at 15 parts per billion — but for bottled water, according to the US Food and Drug Administration, the limit is 5 parts per billion. This presentation will provide the audience with an understanding of how lead gets into our drinking water, lead exposure health concerns, how testing for lead in water should be performed, and what corrective actions can be taken to reduce lead in water exposure when a lead hazard exits.
