Water source & infrastructure
Where Auburn's water comes from
Auburn's drinking water is drawn from underground aquifers through wells.
Groundwater is naturally filtered through rock and soil layers, generally requiring less treatment than surface water. However, it can contain naturally occurring contaminants like arsenic, radon, and minerals.
Agricultural activity, septic systems, and industrial operations near well fields can introduce nitrates, pesticides, and volatile organic compounds.
The system is operated by local government ownership and serves approximately 5,089 people through 3 water systems.
Water bodies near Auburn
Auburn is located near 1 notable water body. These water bodies contribute to the regional watershed and may indirectly affect groundwater quality.
