ROOF works in partnership with Thurston County to provide well water sampling services for Rochester community residents. Individuals can use this service to check the quality of residential, business, or school well water. Sample bottles may be picked up during business hours at the ROOF Center at 10140 Highway 12 SW in Rochester. Filled bottles may then be returned to ROOF on Tuesday mornings from 9:00 am to 12:00 noon, or they may be returned directly to the Thurston County Health Department in Olympia.
