About Us

Our Environmental Health team protects the public’s health by promoting best prevention practices through science, education, guidance, and fostering public trust; and enforcement of laws and ordinances in the City of Nashua. The goal is to create a healthy and well informed public with a balanced integration of human health and environmental protection.

Food Service Inspections

The Environmental Health team protects the safety of Nashua's residents and prevents foodborne illness and injury through inspection, enforcement, and education by environmental health specialists. All food service establishments (restaurants, grocery stores, temporary food stands, etc.) in the City of Nashua are required to follow a set of food safety rules (Nashua Revised Ordinance Ch. 170, He-P 2300) and undergo routine inspections in order to maintain the safety and security of Nashua's food supply.

Swimming Pool & Spa Inspections

The Environmental Health team ensures that recreational water facilities (pools and hot tubs) are clean, healthy, and safe for all residents.

General Environmental Health Hazards

Note that in the above chart, classification of complaint type changes between 2018 and 2019.

Arboviral Surveillance

The Environmental Health team's arboviral surveillance program oversees the collection of mosquitoes that are analyzed for Eastern Equine Encephalitis (EEE), West Nile Virus (WNV), and Jamestown Canyon Virus (JCV).

The graph below and to the right highlights all positive results for Eastern Equine Encephalitis, Jamestown Canyon Virus, Powassan Virus, and West Nile Virus in human, mosquito, and animal specimens in the state of New Hampshire from 2015-2018. The graph below and to the left shows the number of specimens tested in comparison to the number of positive results for that same time period. A positive result for all arboviral tests in mosquito batches occurs 0.17% of the time.

Bed Bugs

The Environmental Health team offers Nashua residents guidance on how to deal with bedbugs. If you have a concern about bedbugs, please take the time to educate yourself before you make any decision about furniture disposal or pesticide usage.

The graph to the right illustrates where pest professionals typically encounter bed bugs across the United States. For example, 16% of U.S. pest professionals encountered bed bugs in retail stores during 2018.


The Environmental Health team recognizes mold as a public health concern. We provide technical assistance and advice to the public and other agencies. We also distribute current information and other resources regarding mold and moisture control.

Mold Testing

We do not provide mold testing, nor do we conduct inspections to determine mold contamination. Mold testing is not recommended, primarily because there are no standards to determine acceptable levels of mold growth.

Spotting a Mold Problem

If you can see mold growth, or if there is a distinctive moldy odor present, you probably have a mold problem. It is recommended to investigate the problem area, look for moisture, and then fix the moisture problem. Unless the source of moisture is removed and the contaminated area and/or materials are cleaned and disinfected, mold growth is likely to reoccur.

Ways to Prevent Mold

  • Clean and dry spills and floods within 24 hours

  • Dry out wet building materials and carpets within 24 hours

  • Keep home clean and dry

  • Reduce indoor humidity levels below 60%

  • Vent moisture from showers, cooking and dryers to the outside
