Department of Health Announces Beginning of 2023 Wet Season Perc Testing
The Anne Arundel County Department of Health Bureau of Environmental Health will start annual wet season site evaluations and percolation tests on January 23, 2023. Wet season testing is arranged on a first-come, first serve basis. Appointments are being accepted and applicants are encouraged to submit applications as early as possible so that each site may be properly evaluated for sewage disposal systems. Wet season applications for mound sewage disposal systems must be received by March 1, 2023 and tested by March 10, 2023. All other applications for testing must be received and scheduled by March 31, 2023.
The wet season test period is set for Anne Arundel County by using data from a network of monitoring wells to determine groundwater levels. Properties located in areas with certain soils and high-water tables require testing during this season of the year. The highest water table is usually experienced during February, March and April. If water levels fall quickly, wet season testing could be ended prior to the normal closing date of April 30.
Wet season testing helps avoid inaccurately assessing the ability of the septic system to work in all seasons of the year. Information provided by the site evaluation and perc testing is used to determine the size and type of septic system that can be installed on a specific lot. Factors such as slopes or adjacent wells can reduce the space available. In addition, adequate land must be set aside for at least two future replacement systems. Depending on the results of the evaluation, this may mean reducing the size of the house and the size of the septic system to meet requirements. In some cases, because of adverse soil or groundwater conditions, a property may only be developed when public sewer is available.
