Application processing is handled on a first-come, first-served basis. For a percolation test to be conducted, an application and the associated $267.75 per lot fee ($255.00 application fee plus $12.75 technology fee) must be submitted to the Department of Permitting Inspections and Enforcement, Licensing Office via mail or by placing it in the Licensing drop box located in front of the building at 9400 Peppercorn Place, Largo, MD, 20774.
To obtain an application to perform PERC testing, please download and complete the Percolation Testing Application (PDF) form.
No tests will be conducted until the application has been submitted and processed. Percolation testing applications that were previously received by the Health Department will be acceptable for this wet season. Reapplication is not needed unless additional lots are being tested that were not indicated in the previous applications.
