For the past three weeks, we've talked about the dangers to drinking water quality posed by water storage facilities, and discussed what you can do to combat them. But there's another source of drinking water contamination that's gotten a lot more press in the past few years, and that's the distribution system. Lead and copper pipes are known for their ability to leach metal into the water they contain. When the pipes are particularly exposed or the water chemistry is particularly favorable, they can leach a lot . If your customers have an increased interest in getting their water tested---or you'd like a refresher on how lead and copper sampling works yourself---this video from AWWA can be a great place to start. The two-and-a-half minute video briefly outlines the basic provisions of the Lead and Copper Rule, and goes on to discuss the proper technique for collecting lead and copper samples. The Quick Reference Guides mentioned in the video can be found on the USEPA website here . The page with additional resources on the rule is here . To see what consumer information resources other utilities and states have developed for the Lead and Copper Rule, search our document database using the category Lead and Copper and the type Factsheets/Case Studies.
