1 <br /> <br />WS – Item #4 <br />WORK SESSION STAFF REPORT <br />Work Session Item No. 4 <br /> <br /> <br />Date: April 4, 2016 <br /> <br />To: City Council <br /> <br />From: Diane Hankee and Erin Heydinger, WSB Engineering <br /> <br />Re: Adoption and Implementation of Wellhead Protection Plan <br /> <br /> <br />Background <br /> <br />On February 26, 2016, the Minnesota Department of Health (MDH) notified the City of <br />Lino Lakes that its Part 2 Wellhead Protection Plan (WHPP) was officially approved. <br />The preparation of the City’s WHPP is a requirement of Minnesota Rules 4720.5100 to <br />4720.5590. The goal of the Plan is to prevent human-caused contaminants from entering <br />the water supply wells and to protect all who use the water supply from adverse health <br />effects associated with groundwater contamination. The Plan falls under the jurisdiction <br />of the MDH and consists of two parts (Part 1 and Part 2). <br /> <br />Part 1 <br />Part 1 of Lino Lakes’ WHPP was completed in 2014. Part 1 is a technical exercise that <br />uses groundwater modeling to delineate the wellhead protection area (WHPA), Drinking <br />Water Supply Management Area (DWSMA) and includes a well and aquifer <br />vulnerability assessment. Part 1 addresses the three municipal water supply wells used <br />by the City and the associated source water aquifer. <br /> <br />Part 2 <br />Part 2 of the WHPP describes how the results of the Part 1 can be applied to best protect <br />a community’s water supply. Data elements were collected and interpreted, and then <br />impacts of changes in land and water use were assessed. This allowed issues, problems, <br />and opportunities to be identified and included in the WHPP. <br /> <br />Next Steps <br />The goals and objectives of the Part 2 WHPP focus on managing potential contaminant <br />sources within the DWSMA, reducing the potential contaminant pathways to the source <br />water aquifer that may be provided by private wells, educating property owners and water <br />supply users, and working with the cities within the DWSMA to ensure proper <br />management of the portion within their respective community. Once adopted, the City <br />must begin implementation of these objectives. Specific goals outlined in Chapter 5 of <br />the Part 2 Plan fall under the following categories: <br /> <br />A. Well Management <br />B. Public Education
