Purpose

Establish a procedure to determine baseline groundwater quality before certain construction in rural areas, by requiring testing of water-supply wells near proposed projects.

Definitions relevant to this section

• landowner: the person who owns the land where a private well is located, or their lessee if the lessee uses the well, or the operator of a public well.
• project: a project in a rural area that must prepare an environmental assessment worksheet under Minnesota Rules part 4410.4300.
• rural area: any part of Minnesota not within a statutory city or home rule charter city.

What the bill requires (main provisions)

• Before construction begins on a rural project, the project owner or operator must test water-supply wells nearby to establish a groundwater quality baseline.
• The project owner/operator must hire an independent third party to collect well samples and arrange for analysis at a laboratory accredited by the Department of Health.
• Landowner consent is required before sampling any well.
• Testing must occur for all wells located within a two-mile radius of the proposed project, unless a landowner does not consent to sampling.
• Landowners must be given free access to the test results for their own well.
• The third-party contractor must report the testing results to the Environmental Quality Board (EQB), and the results must be stored in a database maintained by the EQB as described in section 103H.175 and also reported to the Minnesota Geospatial Information Office.

How this works in practice

• The process ties into existing environmental review requirements, since the relevant projects are those that would trigger an environmental assessment worksheet under Minnesota Rules.
• The results create a baseline database to inform future decision-making and monitoring related to groundwater in rural areas.

Data management and reporting

• Results must be submitted to the Environmental Quality Board and the Minnesota Geospatial Information Office.
• Data must be maintained in a centralized database referenced by 103H.175.

Landowner rights and protections

• Landowners must give consent for sampling.
• Landowners must have free access to the test results for their own wells.

Relationship to existing law and notable changes

• Creates a new requirement in Minnesota Statutes Chapter 103H (section 103H.176) for well testing in rural areas prior to project construction.
• Establishes a formal process for third-party sampling, independent analysis, and centralized data storage that integrates with state agencies (EQB and MGIO) and with the Department of Health for laboratory accreditation.

Significance and intended impact

• Improves baseline understanding of groundwater quality near rural development.
• Increases transparency for landowners through access to results.
• Creates an official data repository to support groundwater management and future project planning.
