North & East Metro Groundwater Management Area Update

The North and East Metro Groundwater Management Area (GWMA) advisory team met through an online meeting on May 29th. The following were the agenda items discussed at the meeting:

  • An update on the implementation of the North and East Metro Groundwater Management Area plan
  • A discussion on the Governor’s Executive Orders as they relate to the DNR’s water-related responsibilities
  • An update on the 3M settlement and drinking water supply planning
  • A discussion on 2040 projected water demands using the transient groundwater flow model
  • Summaries of water conversation reporting by public water suppliers in the GWMA
  • A presentation on the City of Woodbury’s irrigation efficiency project

The next meeting date is to be announced, but is planned for November 2020. Meetings are open to the public and an announcement will be posted on both the GWMA’s site and Know the Flow when the date, time, and location have been determined. You can also sign up to receive email updates here.


The DNR has designated an area in the north and east portions of the metro region as the North & East Metro Groundwater Management Area (GWMA), which includes Washington and Ramsey counties, along with portions of Anoka and Hennepin counties. The Anoka County communities in this GWMA are Blaine, Centerville, Circle Pines, Columbia Heights, Columbus, Fridley, Hilltop, Lexington, Lino Lakes, and Spring Lake Park. The designation as a GWMA “allows a more comprehensive and focused approach to ensuring that groundwater supplies remain adequate to meet human needs, while protecting lakes, streams and wetlands”.

Minnesota Groundwater Contamination Atlas

The Minnesota Pollution Control Agency (MPCA) has published a new tool: the Minnesota Groundwater Contamination Atlas.

“A tool for learning about polluted groundwater at sites around the state”, the atlas allows users to scan the map or utilize a text-based search to find sites by address, zip code, county, municipality, or site name. As of June 2020, when the atlas went live, the tool only shows active state Superfund sites. Data from other sites will be added in future phases.

In addition to viewing mapped groundwater areas of concern, users can read the contamination story of a particular site and download data. The contamination story for each Superfund site contains a summary of the contamination and remediation or clean-up efforts. Specifically, each story addresses:

  • What is the source of the contamination?
  • What is the contaminant?
  • Where is the contaminated groundwater?
  • Are there drinking water impacts? Included in this section is a short narrative and a graphic that explains where drinking water comes from in the area.
  • Is soil or sediment contaminated?
  • Are their vapor concerns?
  • What cleanup work has been done?
  • What contamination remains at the site? A graphic is included for some areas, showing how deep the contamination extends underground.
  • Future actions.

MPCA received funding in 2017 from the Minnesota Environmental and Natural Resources Trust Fund for the purpose of making groundwater data from Superfund sites more accessible to the public and more useful for technical users. This atlas is the result of their 3-year project, supported by technical assistance from the Minnesota Department of Health and Minnesota Department of Agriculture.

As stated above, this first phase of the atlas displays only areas of concern from Superfund sites. As additional funding becomes available, MPCA has plans to expand the atlas by integrating additional data from other remediation programs.

Water Your Yard and Garden with the Help of a Rainbarrel

The Mississippi Watershed Management Organization (MWMO) has put together a quick guide and how-to video for installing and using a rainbarrel in your yard. You can use rainbarrels to collect rainwater to water your lawn, gardens, plants, and more. Collecting and using rainwater reduces the amount of potable water used for watering. It also helps to reduce the amount of stormwater that runs off of your roof and into your stormdrain, which carries pollutants into our water resources.


Click here to read the MWMO’s quick guide on tips and considerations when installing and using a rainbarrel. And see the video below that they published on YouTube, which demonstrates the basics of rainbarrels and the installation process.

New Video: Our Lakeshore Connection

Anoka County Water Resource Outreach Collaborative partners worked with several local lake associations to produce and fund a new video: Our Lakeshore Connection. The animated video is about lakeshore restoration and stewardship. The beginning of the video helps viewers to understand lakes and what makes a healthy lake and lakeshore. The rest of the video gives viewers steps they can take to become good stewards of their lakeshore. Watch the video below!



The video has also been broken down into two parts, depending on the interest of viewers and those using the video to educate others:

For more resources on how to restore your lakeshore, visit For assistance, contact your lake association, local watershed management entity, or soil and water conservation district.

The following are the sponsors of the video:

Reminder: Anoka County Currently NOT Accepting Water Samples

Reminder: Anoka County Environmental Services is currently NOT accepting water samples. Well Water Wise week 2020 was canceled. 

The Environmental Services Department is exploring options for the potential re-opening of the well water testing program in the near future. However, this is still in the works and no information is available at this time. As the public is currently not permitted beyond the 1st floor of the Government Center, the Department is looking into alternative options. Please check back on this website or the official website at – information will be posted on both of these sites when a plan has been determined.

In the meantime, if you need to test your water immediately, see this list of private, state-certified labs that you can utilize. We appreciate your patience!

NPDES General Feedlot Permit Accepting Comments

The MPCA is currently accepting written comments on the draft National Pollutant Discharge Elimination System General Feedlot Permit until 4:30 pm on Thursday, July 23rd, 2020.

The proposed permit includes new measures to limit the leaching of nitrates from manure spread on farm fields by extending the required cover crop period for manure application to October (cover crops are required to mitigate the risk of nutrient pollution to groundwater and surface waters from manure) and restricting manure applications in September and October. The draft permit also includes streamlined record-keeping requirements, a revised permit format, and an online application process that will save feedlot owners time. The new permit will become effective February 21st, 2021.

More information on the permit, information on submitting comments, and links to the draft permit and other pages can be found at
