The Barnstable County Laboratory provides analytical services both directly to the public and to the municipalities on Cape Cod. One primary directive of the laboratory is to provide high quality analyses of various contaminants in drinking water. Accordingly, the laboratory assists the water districts and departments on Cape Cod in meeting the monitoring requirements necessary for adherence to state and federal water quality standards. Water districts and departments benefit from the flexibility of the laboratory to assist when periodic problems arise, such as the seasonal and transient occurrences of bacteria. The Laboratory also provides analytical services to owners of private drinking water wells.
