LEONARDTOWN, Md. – Due to declining seasonal groundwater levels, the St. Mary’s County Health Department (SMCHD) has suspended wet season perc testing. SMCHD staff will conduct the last perc tests for the season on Friday, April 29, 2022.

Health department officials are citing declining groundwater levels as the reason, made clear by observing conditions within a network of monitoring wells in the county.

All perc test applications that were not scheduled and evaluated will be suspended and rescheduled first when groundwater levels are adequate for the next wet season, expected in 2023.

Applicants may also request a refund; however, they must then reapply when the wet season returns and they will lose their place/priority for scheduling during the next perc testing season.

For more information, please contact the Environmental Health Division at (301) 475-4321.
