Located on Maxwell Air Force Base, NAREL provides radiological monitoring data to support rulemaking and radiological emergency response activities. The Environmental Radiation Ambient Monitoring System is the only nationwide environmental radiation monitoring network in the United States. NAREL also supports Superfund and enforcement activities with laboratory and field measurements and technical assistance for radioactive and hazardous chemical (mixed waste) contaminants. The facility includes a state-of-the-art radioanalytical laboratory and office space.
Sustainable Features
- Twenty-five 4.5-kilowatt solar lighting fixtures in the facility’s back parking lot illuminate the space, making travel safer after dark. The lights are motion- and light-sensitive; they store the power needed to operate for approximately five days in two 100-amp batteries and reduce power to 50 percent when the lot is empty. The solar parking lot lights generated an estimated 27,375 kilowatt-hours (kWh) of electricity in FY 2022.
- An air handler condensate recovery system collects about 800,000 gallons of water per year for the facility's cooling tower, which accounts for 65 percent of the facility's water use.
- The laboratory has eliminated all forms of single-pass equipment cooling.
- The infrastructure replacement project (IRP) included new laboratory and office areas, as well as two new air handling units capable of providing heating, ventilation and air conditioning for the entire main laboratory facility. It also included a new exhaust fan sized to serve the main laboratory fume hoods. The IRP reduced the number of fume hoods.
- No landscape irrigation water is used at the laboratory, as grasses and shrubs are climate-appropriate and survive on natural rainfall.
- EPA conducted a facility resiliency assessment at this facility in FY 2023.
