What Happens During a Sanitary Survey of a Well System?

A sanitary survey is a full check of the water system. It looks at the source, treatment, pumps, storage, distribution, samples, records, and daily management. The surveyor looks for a problem that could let dirt or germs enter the water. They also check whether staff can run the system in a safe and steady way. Operators should show current records and explain what they really do. Do not hide a broken part or make a new log just for the visit. A serious finding may be called a significant deficiency. The Ground Water Rule can require a fix for that finding or for confirmed fecal contamination at the source. The utility must complete the approved action and keep proof that the work was done. Treat the survey as a helpful second look at the well. A finding at the wellhead, such as a damaged seal or a missing vent screen, can let germs reach the water, so fix it on time and record the date the repair was finished.
