Perc Test
Announcement from Environmental Health
Currently wet season percolation testing is not open. The Division of Environmental Health staff are closely monitoring the water table levels. In accordance with COMAR 26.04.03, percolation testing/site evaluations for subdivision of land should be performed only at the time of the year when the highest water table can be expected. Our office will notify the public as soon as wet season testing begins. Please refer to our Percolation Testing Guidance Document for more information. Our office will schedule wet season perc testing directly with the chosen licensed septic installer on your application.
Anyone who has questions should contact Calvert County Health Department, Division of Environmental Health at 410-535-3922.
What is a Percolation Test?
The percolation test is designed to determine the soil suitability of a site for a subsurface private sewage disposal system (i.e. septic system). More specifically, a percolation test measures the ability of the soil to absorb liquid. Septic system designers use the results of percolation tests to properly construct septic systems. The uniform slowest rate of drop of the water level over a measured time interval is converted to minutes per inch and used as a basis of design in determining the septic system size.
Soil conditions are one of the criteria used for determining the suitability of a site for construction. Critical area designations, slopes, zoning restrictions and other conditions are also factored into the approval process for a construction permit.
