EC-SDC Grant Program for OTM / Non-Profit NN Systems

Emerging Contaminants-Small or Disadvantaged Communities Grant Program for Other-than-Municipal/Non-Profit Non-transient Non-community Public Water Systems

ATTENTION: Funding for PFAS and manganese in small drinking water systems now available.
Please check the EC-SDC Grant Announcement and the EC-SDC FAQ resource for more details on how to prepare and submit an application. Applications due by July 31, 2024.

The 2021 federal Bipartisan Infrastructure Law (BIL) provided funds to assist public water systems in small or disadvantaged communities in addressing emerging contaminants. This program is known as the Emerging Contaminants in Small or Disadvantaged Communities (EC-SDC). The Wisconsin DNR received grant funds from the EPA and designated $4,000,000 to provide financial assistance to OTM and non-profit NN public water systems serving small or disadvantaged communities. This program focuses on PFAS and manganese as emerging contaminants.

What are OTMs?

Other-Than-Municipal Community (OTM) public water systems are not owned by a government or municipality and serve groups of 25 or more year-round residents. OTMs can include mobile home parks, apartment buildings, and condominium associations that are not on city or municipal water.

What are non-profit NNs?

Non-Transient Non-Community (NN) public water systems are nonresidential and regularly serve groups of at least 25 of the same people over six months of the year. NNs can include schools and daycare centers that are not on city or municipal water. A non-profit NN is a government entity or an organization that is described under section 501(c)(3), 501(c)(4), or 501(c)(6) of the Internal Revenue code which does not lobby.



Who can apply?

You must answer "yes" to each of the following three questions:

☑   Are you the owner or authorized representative of an OTM or non-profit NN public water system?

☑   Does your public water system serve a community that has a population less than 10,000?

☑   Does your public water system have either PFAS or manganese contamination?

  • PFAS contamination occurs when the result of a sample taken at an entry point in the water system contains either:
    • PFOA or PFOS of 4 ng/L or greater, or
    • PFAS with a hazard index value (WI DHS or proposed EPA) of 1.0 or greater.


  • Manganese contamination occurs when the most recent sample taken at an entry point or source water location in the water system has a sample result of 300 µg/L or greater.
Project Eligibility
