Soil tests, including deep soil test pits and percolation tests, are needed on properties served by on-site septic systems to determine site suitability and limitations for on-site sewage disposal. The soil testing also provides critical information needed for locating, sizing and designing the septic system. Soil testing is needed when proposing projects and submitting plans for new property development, subdivision, septic system repair, and B100a project reviews. Only a sanitarian can make the final determination if a soil test is needed. Please call or email to inquire.
