What is the NH Department of Environmental Services?
The NH Department of Environmental Services (NHDES) is New Hampshire's state environmental agency, responsible for protecting the state's air, water, land, and coastal resources. Its work spans permitting, regulation, monitoring, and public information across issues such as drinking water, wastewater, wetlands, air quality, solid and hazardous waste, and shoreline management.
For residents and businesses, NHDES is typically the place to go for environmental permits, compliance requirements, water-quality data, and guidance on handling waste or developing near protected resources. Municipalities, contractors, and regulated facilities often interact with it most; homeowners may use it for well-water and septic questions.
A practical next step is to identify which program covers your issue—air, water, waste, or wetlands—and check that program's guidance or permit pages on NH Department of Environmental Services before starting an application.
How do I apply for a permit or license through NHDES?
The New Hampshire Department of Environmental Services (NHDES) handles permits and licenses through its own online services and program-specific application processes rather than a single universal form. To apply, start by identifying which NHDES program regulates your activity (for example, air, water, wetlands, waste or drinking water), then follow that program's application instructions and submit through the channel it specifies.
A practical starting path
- Identify the program and permit type. NHDES regulates many different activities, so the right application depends on your project. Use the department's site navigation or search to find the relevant bureau or program page.
- Check whether an online account or portal is required. Some NHDES permits are filed through the department's online permitting services; others use downloadable forms submitted by mail or email.
- Gather supporting materials early. Site plans, maps, technical reports and fees are commonly requested. Missing attachments are a frequent cause of delays.
- Confirm fees and review timelines on the specific program page before submitting, since these vary by permit type.
- Track your application through whatever status tool the program provides, and respond promptly to requests for additional information.
Decision criteria
- New project vs. modification: Modifications to an existing permit often use a different, shorter process than a first-time application.
- Individual vs. general/blanket permit: Some routine activities qualify for a general permit with simpler requirements; check eligibility before filing a full individual application.
- Pre-application contact: For complex projects, contacting the relevant NHDES program before filing can clarify requirements and save rework.
As a next step, open NH Department of Environmental Services and navigate to the program area matching your activity to find the exact application forms, submission method and fee schedule.
How can I report an environmental violation or complaint in New Hampshire?
In New Hampshire, environmental violations and complaints are handled by the NH Department of Environmental Services (NHDES). The department is the state agency responsible for air, water, waste, wetlands and related environmental programs, so it is the right starting point for most pollution or permit-related concerns.
What to have ready
Before you contact NHDES, gather details that help staff act quickly:
- Location: street address, town, and any landmarks or waterbody names.
- What you observed: the specific activity or condition, such as dumping, discharge, smoke, odors or disturbed wetlands.
- When: dates and times, especially for ongoing or intermittent problems.
- Who: business or property names if known, and whether the activity appears permitted.
- Evidence: photos or video taken from a safe, public location.
Practical next steps
- Visit the NHDES website and look for its complaint or reporting section; many state environmental agencies provide an online form or a dedicated phone line.
- If the situation is an immediate hazard—such as a spill flowing into a stream or stream—call rather than relying on a form, and follow any emergency instructions the agency provides.
- Keep a record of your report and any reference number.
A concrete scenario
Suppose you see muddy water leaving a construction site into a nearby brook. Note the address, the time, and the color and extent of the plume, and photograph it from the road. That combination of location, timing and visible evidence is what an inspector needs to decide whether a site visit is warranted.
Decision criterion
Report through NHDES when the concern involves environmental permits, pollution or natural resources. For immediate threats to health or safety, use emergency services first.
Where can I find NHDES data, maps, or water quality reports?
Start at the New Hampshire Department of Environmental Services site itself: NH Department of Environmental Services. NHDES publishes water quality reports and mapping tools under its own programs, so the homepage is the right entry point, then navigate to the specific division for the data you need.
Where to look on the NHDES site
- Water quality reports: look under the Water Division or the surface water quality program pages, which carry assessment and reporting material.
- Maps and geospatial data: check the site's GIS or mapping section for interactive viewers and downloadable layers.
- Monitoring and sampling data: look for the program that collects the data (e.g., beach monitoring, lakes, rivers, wells) rather than a single central data page.
A practical next step
Decide whether you need a report (narrative assessment, good for context and citations) or a dataset or map (good for analysis or locating a site). If it's a specific waterbody, search the site for its name plus "water quality" or "assessment"; if it's a broad question like "is my local beach safe to swim at," go to the monitoring program page directly.

If a report you need isn't posted, contact the relevant NHDES program directly; staff often provide data on request.
How do I find out about beach advisories or drinking water notices?
Use the New Hampshire Department of Environmental Services site as your starting point for both kinds of notice, but expect them in different places: beach advisories are seasonal, public-health updates, while drinking-water notices usually come from your water system and are often posted where you pay your bill or on your utility's own site.
Beach advisories
Check NH Department of Environmental Services during the swimming season for current beach status and advisory information. Advisories typically flag elevated bacteria or other health concerns at specific beaches, so look for the beach name and the dates rather than a single statewide status.
Drinking water notices
Your community water system is the primary source for boil-water orders, do-not-drink notices and other compliance alerts. If you receive water from a municipal utility, check its official website or the notice left at your door. For private wells, DES provides guidance on testing and interpreting results rather than issuing system-wide notices.
Practical next step
If you are planning a beach day, check the DES advisory page the morning you go, since conditions can change quickly after rain. If a drinking-water notice arrives, follow the utility's instructions exactly and keep the notice until the all-clear is issued.
What grants or funding programs does NHDES offer to residents and municipalities?
The New Hampshire Department of Environmental Services (NHDES) offers grants and funding programs aimed at both residents and municipalities, though the specific mix changes with each budget cycle and program. The department's main site, NH Department of Environmental Services, is the place to confirm current offerings, eligibility and deadlines.
What residents typically look for
- Private well and septic assistance: Programs have historically helped homeowners with testing, repair or replacement of failing septic systems and contaminated wells, often income-qualified.
- Lead and radon: Funding and testing support for reducing lead in drinking water and radon in air.
- Recycling and household hazardous waste: Grants or cost-share arrangements that flow through municipalities, which then run collection events for residents.
What municipalities typically look for
- Clean water and wastewater: Loans and grants for treatment plant upgrades, combined sewer overflow fixes and stormwater infrastructure, frequently administered with state revolving loan funds.
- Landfill closure and solid waste: Cost-share for closing old dumps and improving transfer stations.
- Source water protection and watershed work: Grants for wellhead protection, dam removal and stream restoration.
- Air and energy: Diesel retrofit or emission-reduction funding for fleets and schools.
A practical way to decide
Start from the problem, not the program name: a failing septic system, a sewer upgrade, a school bus retrofit and a wellhead protection plan each sit in a different office. Check whether the program is a grant (no repayment), a low-interest loan (repayment required) or a cost-share (you pay a portion). Municipalities often need matching funds and a public vote, which affects timing. Residents usually need income documentation and proof of ownership.
The most useful next step is to search the NHDES site by topic — "septic," "well," "wastewater," "recycling" — and check the grants or funding page for the current application window, since programs open and close rather than run year-round.
