Since 1998, the Business Pollution Prevention Program has
provided technical assistance to businesses operating near the 29 municipal wells serving the city's of Olympia, Tumwater, Lacey, and Grand Mound. Wellhead Protection protects public drinking water supplies by
managing the land surface around a well where activities might affect the quality of the water. The County has worked with the city representatives in these wellhead protection areas to
identify and gain the participation of over 80 businesses. [Click picture for enlarged view]
Businesses in the County's wellhead protection areas voluntarily allow County inspectors to conduct inspections
to ensure compliance with Thurston County's Nonpoint Source Pollution Ordinance (Article VI [PDF] of the Sanitary Code). These inspections also provide
an opportunity for technical assistance aimed at minimizing hazardous material use and on-site storage. Inspectors also assist businesses in developing spill response plans, spill prevention, and recycling opportunities.
If you have questions about the wellhead protection program, please call Thurston County Environmental Health at
360-867-2664 or TDD 360-754-2933, Monday through Friday from 8:00 a.m. to 5:00 p.m.
