What is the purpose of monitoring wells or observation wells near septic fields?

Monitoring wells near septic fields are used to track groundwater quality and how the septic system affects it over time. By sampling water from these wells, you can see whether contaminants from the leachate—such as nitrates or bacteria—are reaching the groundwater, how concentrated they are, and how fast they move. This information helps determine if the system is functioning properly, if the contaminant plume is contained, or if it’s migrating toward drinking-water sources or surface waters. Regular monitoring provides trend data that can reveal a failing system early and guide needed repairs or design changes to protect health and the environment. They aren’t meant to attract wildlife, harvest groundwater for irrigation, or measure air quality.
