Laboratory and Monitoring Services
Each year thousands of samples are analyzed in Arkansas Department of Energy & Environment (E&E) Division of Environmental Quality's (DEQ's) state-of-the-art laboratory. The resulting data is invaluable to Arkansans who want to learn more about the water quality in their favorite nature areas or about the air quality in a given town.
Air Chemistry Laboratory
The Air Chemistry lab operates a statewide monitoring network, including necessary repair, maintenance and quality control activities. The monitoring network provides the data to measure attainment status of both state and national ambient air quality standards. Pollutants including lead, ozone, particulates (PM10 and PM2.5 or PM fine), and oxides of nitrogen, carbon monoxide, and sulfur dioxide are monitored at specific sites around the state. The values are used by the DEQ’s Air Office to determine if air quality is within the guidelines set by EPA. Data collected is entered into EPA’s national database.
Environmental Multimedia Laboratory
Employees in the Laboratory and Monitoring Services' environmental laboratory analyze ambient water quality samples from hundreds of monitoring sites around the state. They also analyze samples from wastewater plants to ensure compliance, and from groundwater for aquifer protection.
Whether you are a citizen wanting to know the quality of the lake, river or stream near you or an environmental consultant needing information to prepare a permit application for a client, you can download water quality data.
Laboratory Accreditation Program
DEQ also certifies laboratories in Arkansas and across the US, ensuring that data submitted for development, planning, permitting or other functions in our state meet strict standards.
