Adequate separation must be maintained between all water supply wells and infiltration systems. Unlike municipal public supply wells, modeling and other technical analysis is rarely done to determine appropriate separation distances for these wells. We recommend one of the following three approaches to determining a separation distance between an infiltration system and a water supply well.
 
−
*Follow Minnesota Department of Health guidelines, which specify a minimum 100 foot horizontal separation between any infiltration BMP and a sensitive water supply well, and a 50 foot minimum horizontal separation between any infiltration BMP and all other water supply wells. Sensitive water supply wells may be identified using existing reliable groundwater maps (e.g. MDH vulnerability maps, Minnesota Department of Natural Resources (MDNR) [https://www.dnr.state.mn.us/waters/groundwater_section/mapping/index.html County Atlases]), or by applying [https://files.dnr.state.mn.us/waters/groundwater_section/mapping/groundwater-atlas-user-guide.pdf MDNR groundwater sensitivity criteria (see page 8)]
 
−
*Applying the guidance found at [https://stormwater.pca.state.mn.us/index.php?title=Screening_assessment_for_contamination_at_potential_stormwater_infiltration_sites#Determining_if_adequate_separation_can_be_achieved_between_a_potential_contamination_source_and_the_BMP this page], determine an appropriate separation distance based on a mounding analysis. We recommend adding an additional safety factor if runoff delivered to the infiltration practice is located in a stormwater hotspot or has the potential to contain mobile organic chemicals or pathogens.
 
−
*Calculate a time of travel. This can be done if there are sufficient data to apply Darcy's equation V= KI/n, where V is the groundwater velocity, K is the horizontal hydraulic conductivity, I is the horizontal hydraulic gradient, and n is the effective porosity.

A tour of the Minnesota Stormwater Manual content

This page provides an overview and tour of the content in the Minnesota Stormwater Manual. The focus is on understanding content. There is other guidance on the manual wiki, including the following.

Types of information in the Manual

A good way to see the types of information in the Manual is to click on Index (Categories) in the left toolbar. Categories are a way of grouping links to pages that have a similar theme or subject matter. Visualizing the categories provides insight into the information in the Manual.

Some examples of the information in the Manual include the following.

  • Technical: The Manual mainly provides technical information to users. Examples include the following. The links following each item provide example pages in the Manual.
    • Design of best management practices (BMPs) [1]
    • Construction of BMPs [2]
    • Operation and maintenance of BMPs [3]
    • Assessment of BMP performance [4]
    • Models
    • Pollutant information
  • General
  • Permit (Regulatory)
  • Case studies
  • Fact sheets
  • Checklists and inspection sheets
  • Cost information
  • Education

Images (photos, schematics, etc.)

Tables

Events, News, Funding
