Briefing on Bacteria Levels and the District of Columbia’s Water Supply

September 23, 2004

At the end of August, WASA completed its 95th consecutive month surpassing the standard under the Safe Drinking Water Act, but this month’s routine testing in the District’s water system indicates that, although drinking water standards are being met, levels of bacteria may be rising.

Coliforms are naturally occurring bacteria that are found nearly everywhere. Most coliforms are harmless, and they are used as an indicator by water systems to monitor for any potential increases in bacterial growth in a water distribution system.

Water systems routinely test drinking water samples for their microbiological content on a monthly basis.
