Soil Testing

Soil Test Application

The Durham Department of Health accepts applications for soil tests to determine the suitability of lots to accommodate subsurface sewage disposal systems. The soil tests, comprised of deep test pits and percolation tests, are conducted in the spring usually beginning in mid-March. Applications for the spring testing season should be filed by mid-April. 

Also, testing is conducted in the autumn beginning in October. Applications for the autumn testing should be submitted by early December. Testing conducted in the autumn in areas where high groundwater can be expected may require monitoring of the groundwater level during the next wet season, February 1 to May 31. 

Investigation of failing septic systems and soil testing necessary for the repair and replacement of existing systems are conducted throughout the year. 

Similarly, testing for the designation of reserve leaching areas in conjunction with proposed additions to houses and construction of accessory structures is conducted during most of the year.

Applications are available on-line (click on “soil test application” above) and from the Health Department located on the second floor of the Town Hall. 

To have an application mailed or faxed, please call (860) 349-8253.
