PFAS Removal Rebate Program for Private Wells

Funding for eligible private well owners to install a treatment system or connect to a water system.

Program Funding Status – June 10, 2024

The Program is no longer accepting applications until further notice. Applicants with pending applications will be contacted within the upcoming weeks to inform them of their application status. 

A second source of funding has been appropriated through House Bill 1547 in June 2022 and per RSA 485-H:9, NHDES is required to adopt rules that govern the Program. While these rules are in progress, they will not be adopted in time for a seamless transition between funding sources. This means that there will be a period of time where application processing will be suspended. We cannot tell you at this time how long the suspension will be, nor if there will be changes to the eligibility requirements for this program. We encourage you check back in to the website for updates and reach out with questions. We will answer them to the best of our abilities. We ask for your patience and understanding during this transition time. 

The PFAS Removal Rebate Program provides a one-time rebate of up to $5,000 per residential address to assist in the installation of a treatment system designed to remove PFAS (point-of-use or point-of-entry) or up to $10,000 for a service connection to a public water system. Note: Treatment installations or service connections completed after September 30, 2019, are eligible for this program. Eligibility must be determined through the application process and approval from NHDES to receive a rebate.


The following entities are eligible to apply for the rebate program:

  • Owners of a single or multiple-unit residential property.
  • Tenants/occupants of a residential property where the owner of the property has not applied for the rebate for the same property.
  • Treatment installers may apply in lieu of an eligible owner or tenant with an appropriate waiver of claims between the two parties.

Contracted Treatment Installer Submitted Applications - Applications submitted by contracted treatment installers on behalf of an owner or tenant will not be accepted if the owner or tenant has paid for eligible services rendered. Eligible services must be completed at no cost to the owner or tenant. 


Please note that NHDES does not approve or recommend treatment installers for residential wells. It is recommended that owners or tenants obtain quotes from multiple treatment installers. A list of New Hampshire Residential Water Systems Service Providers has been compiled by NHDES. This listing does not imply endorsement by NHDES.


Applicants must be able to provide documentation of PFAS concentrations in their private residential drinking water well above one or more of the US Environmental Protection Agency (EPA) Maximum Contaminant Levels (MCLs) and have no offer of an alternate water source (bottled water, treatment or service connection) from a third party that may be responsible for the PFAS contamination. The EPA has set individual MCLs for five PFAS compounds and a Hazard Index MCL for the mixture of four PFAS compounds. The current EPA MCLs are:

Compound MCL in ng/L (nanograms per liter, also expressed as parts per trillion, ppt)
Perfluorooctanoic acid (PFOA) 4.0
Perfluorooctanesulfonic acid (PFOS) 4.0
Perfluorohexanesulfonic acid (PFHxS) 10
Perfluorononanoic acid (PFNA) 10
Hexafluoropropylene oxide dimer acid (HFPO-DA, commonly known as GenX Chemicals) 10
Mixtures containing two or more of PFHxS, PFNA, HFPO-DA, and Perfluorobutane sulfonic acid (PFBS) 1 (unitless) Hazard Index

Please note the above values do not reflect the current NHDES Ambient Groundwater Quality Standards (AGQS) and only reflect eligibility criteria for the PFAS Removal Rebate Program for Private Wells.


  • A completed and signed application form.
  • Pretreatment analytical lab results showing concentrations above one or more of the EPA PFAS MCLs – not required if NHDES collected this sample.
  • Itemized sales receipt(s)/invoice(s) for all associated work.
  • Manufacturer's specification sheets for treatment media and equipment installed, if applicable and available.
  • Post-treatment analytical lab results showing PFAS concentrations below the EPA MCLs – not required for water system connections.
  • Photo documentation of the treatment installed or service connection.
