Perc Tests

A perc (percolation) test is a procedure used to determine the rate at which water or sewage effluent will percolate through the soil. The perc test is only a part of the total lot evaluation used to determine the suitability of a site for on-site sewage disposal. Most lot evaluations in Somerset County are required by Maryland Department of the Environment Regulations to be conducted at the time of the year when the highest water table can be expected. This usually means during February, March, and April, however, monitoring wells are checked weekly to determine the exact testing period. There are a few circumstances that will allow the test to be conducted anytime during the year.

If you are interested in having a perc test, contact us first to ensure that the test can be conducted.
