SepticSmart (Onsite Wastewater Systems)

Septic systems are a common source of groundwater contamination in our country. Unapproved, aging, and failing septic systems have a large impact on the quality and safety of our water supply. Check the records for your septic system and learn more about property transfer requirements.

Well Water

Unlike a public drinking water system, private wells do not have experts regularly checking the water quality before it is sent to the tap. Private well water quality varies from source to source.
