Description: Community water system service area boundaries describe the geographic area that receives drinking water from a given community water system. Knowing these boundaries help to connect water system data (such as, compliance status) with water system customers.

This dataset contains ~44,000 unique service areas across all 50 states. While not 100% comprehensive, these systems cover 99% of all public water system consumers.  ~40% of systems are sourced from state/utility databases. The remaining systems, those with no state supplied boundary, were modeled using machine learning techniques. This effort used state sourced service areas to train a model on dozens of explanatory variables including drinking water intakes in order to approximate service areas where none are publicly available.

This dataset used the 2023 Quarter 4 Safe Drinking Water Information System for establishing the universe of community water systems.
