In the Onsite Wastewater Treatment Systems Program we are responsible for protecting public health and the environment from the potential adverse health and environmental impacts associated with new and repair onsite wastewater treatment systems.
We carry out this responsibility by investigating complaints, reviewing test data, design proposals and inspecting the construction and installation of all onsite wastewater treatment systems to insure conformance with applicable regulations, codes and ordinances.
Wastewater from an onsite wastewater treatment system may contain many types of contaminants such as nitrates, harmful bacteria, chemicals, and viruses. If an onsite wastewater treatment system is failing, designed incorrectly or is not constructed in conformance with applicable regulations, ordinances, codes and construction practices, contaminants may enter the groundwater supply and/or result in surface sewage causing direct exposure to people, animals and the environment.
