The 2002 Water Quality Report is Now Available

June 20, 2003

Dear Customers,

The District of Columbia Water and Sewer Authority (WASA) is happy to provide you with its year 2002 water quality report.

We are once again proud to report that Washington, DC's drinking water met or surpassed all requirements of the federal Safe Drinking Water Act (SDWA) every single day in 2002. This Water Quality Report is the fifth in the series of reports. It provides information on DC's drinking water quality - the source of water, how it is treated and tested, and what it contains. Although some EPA mandated information is repeated each year, the report provides continuing updates on some of the programs and technologies that we use to deliver safe drinking water to your tap. We appreciate your input and comments on our 2001 report and look forward to your continued support of WASA's commitment to supplying you with safe and affordable drinking water.

As the nation continues to deal with increased levels of preparedness and response, WASA has elevated its level of security to reduce system vulnerability. We continue to be thankful for the help and support from concerned citizens in reporting suspicious activities and look forward to your continued support.

I trust that you will find our 2002 water quality report informative and useful.

Jerry N. Johnson, General Manager
District of Columbia Water and Sewer Authority
