Technical Subgroup 1: Drinking Water Supply

This Subgroup will analyze options and deliver assessments and advice to the Government and 3M Working Group and the Citizen and Business Group for long‐term options for drinking water supply and for treatment of existing water supplies that will improve the quality and quantity of drinking water for communities and individuals in the East Metropolitan Area.

Next scheduled meeting


The group will be composed of technical experts from MPCA, DNR, MDH, 3M, Metropolitan Council, and Washington County. The cities of Afton, Cottage Grove, Lake Elmo, Lakeland, Lakeland Shores, Maplewood, Newport, Oakdale, St. Paul Park, Woodbury, and the townships of Denmark, Grey Cloud Island and West Lakeland will each have one representative on the Subgroup. Each community, MPCA, DNR, MDH, 3M, Metropolitan Council, and Washington County can designate one alternate for when their representative is unable to participate in a meeting.
  • The Subgroup will meet at least once a month and more frequently if needed. While all members will be invited to every meeting, actual participation at a given meeting may be driven by the agenda for that meeting. It is understood that those who are interested in specific projects and approaches will be most likely to attend a particular meeting.
  • Technical experts not affiliated with the Subgroup may be invited to consult on topics in their area of expertise.
  • The meetings will be open to the public, and time will be reserved at the end of each meeting for public questions or comments.

Evaluation of potential projects

Potential projects may include private well use alternatives, multi‐municipal drinking water supply concepts, individual municipal drinking water supply systems (including treatment systems), neighborhood connections to municipal systems, drinking water supply alternatives, groundwater studies, and monitoring/modeling needs.
  • Project options will be assessed by the Subgroup. Municipalities will provide information on needs and feedback on emerging ideas. Involvement by particular communities will vary and evolve over time.
  • Under MPCA, DNR and Subgroup direction, technical teams may be created to delve more deeply into specific project approaches and work closely with individual communities on project proposals.
