The most important information contained in this report is that our drinking water quality continues to meet all state and federal regulations. We are committed to providing the highest quality drinking water to our customers. Our laboratory tests our water at the wellhead, at various stages of treatment and within the distribution system for bacteria and a wide range of inorganic and organic chemicals. In fact, we test our drinking water for far more chemicals than required and at a frequency far in excess of local, state and federal regulations. Because of these stringent safeguards, we can reassure all our customers that the water we deliver to them meets all drinking water standards and guidelines. This Drinking Water Quality Report contains extensive water quality information. Click on the page title to view each page.
