The boundaries of the drinking water supply management area are delineated by identifiable physical features, landmarks or political and administrative boundaries. This dataset was developed with the intention of protecting the public drinking water supply and complies with the federal Safe Drinking Water Act, United States Code, title 42 and the State of Minnesota Rule (parts 4720.5100 to 4720.5590).

MDH In general a DWSMA represents the management area for one public water supplier, however in dense populations, individual DWSMAs can extend into another public water suppliers DWSMA which can cause ambiguity in how to manage the area. In order to resolve this, MDH began creating single wellhead plans for multiple public water suppliers who were in close proximity to each other. The West Metro was first wellhead plan created this way and is included in this data set. It was approved in 2025 and consists of 8 public water suppliers with a group pwsid of 2000000. The individual public water suppliers that are part of this DWSMA are as follows: Hopkins (pwsid:1270016) Saint Louis Park (pwsid: 1270050) Eden Prairie (pwsid:1270010) Bloomington (pwsid: 1270001) Chanhassan (pwsid:1100001) Edina (pwsid:1270011) Minnetonka (pwsid:1270031) Richfield (pwsid: 1270045) 1.0 20260331 07313400 TRUE
