The Environmental Protection Agency (EPA) and Oregon Health Authority laws require the District to provide​​ our consumers with a detailed report showing what is in the water they drink. OLWS continually strives to adopt new and better methods for delivering the best quality drinking water standards. The District's testing results continue to meet and exceed state and federal guidelines for public health.
