Health Officials Issue Two "Boil Water Advisories" In East King County
Health officials are telling nearly two thousand people to boil their water tonight -- after two separate water supplies were contaminated by bacteria.

The two water systems are both in eastern King County, and are both named Riverbend, although the Boil Orders are unrelated and the two water supplies are unrelated.

In both cases, residents should boil their drinking water and any other water used to prepare food or wash dishes.

Authorities issued the advisories because routine test samples show the water may be contaminated with E. coli.

One advisory is for the Riverbend Homesites development off of Interstate 90, Exit 32, east of North Bend.

The residential community has 533 homes and about 1,600 residents. The development entrance is off of Southeast 146th Street.

The other advisory is for the Riverbend Mobile Home Park between Renton and Maple Valley. The Riverbend Mobile Home Park has 97 mobile homes and water hook-ups for 46 recreational vehicles.

The park's water was shut off Thursday to repair a broken water line. The bacteria problem could be related to the line break.

The advisories don't affect any other communities.

Residents who use tap water for drinking, cooking, brushing teeth, mixing baby formula, dishwashing, and ice making should bring the water to a rolling boil for one full minute and allow it to cool before use.

Tap water can be used for other purposes.

The state Department of Health is working closely with both water systems to help pinpoint the source of contamination and correct the problems.

Residents will be notified when the advisories end.
