The Environmental Quality Institute
EQI collects scientific data that informs environmental understanding and decision-making. Our nonprofit laboratory monitors water quality in streams and lakes throughout western North Carolina.
We curate reliable and objective data, expand awareness about regional water quality, and provide technical support to nonprofits, local governments, educational institutions, and communities to drive environmental improvements.
Community Impacts
33 Years of Monitoring
EQI has been working with partners and volunteers to monitor western NC waterways since 1990.
200+ Stream and Lake Sites
We sample sites in 17 mountain counties, located in 6 NC river basins. Results are shared with more than 30 partner organizations and agencies.
20,000 Tests Run Annually
Chemical testing is conducted monthly for all sites at EQI’s NC-certified laboratory. Aquatic invertebrate sampling happens each spring and fall.
Announcements
Spring SMIE Biomonitoring Workshop
When: Saturday, April 1, 2023 from 9 am to 4 pm
Where: UNCA and the Ivy River Community Center
Come learn about basic stream ecology, aquatic invertebrates, sampling protocols, and how you can help monitor stream health. No prior experience is required.
Paid Federal Work Study Positions with EQI
We currently have work-study positions available at EQI’s lab through UNC-Asheville and AB-Tech. Please click on the links below to see if you are eligible to apply through either school.
The Volunteer Water Information Network
The Volunteer Water Information Network (VWIN) program began in 1990 and tests stream and lake water for chemical and physical properties. Trained volunteers collect water samples on a monthly basis. These samples are then analyzed for eight parameters at EQI’s state-certified laboratory. Tests include turbidity, total suspended solids, pH, orthophosphate, nitrates, ammonia, alkalinity, conductivity, and sometimes total phosphorus and fecal coliform. This type of monitoring allows an understanding of ecological conditions at the time of sampling.
The Stream Monitoring Information Exchange
The Stream Monitoring Information Exchange (SMIE) program has been sampling streams for bugs (benthic macroinvertebrates) since 2005. Each spring and fall, trained volunteers sample in small groups. Group Leaders with additional experience oversee the sampling and quality assurance protocols. This type of stream monitoring allows a greater understanding of water quality and habitat changes over time based on what is able to live there.
EQI Water Quality Map and Data Portal
EQI’s data is publicly available in our Data Portal. Take a look to see the water quality near your community.
What happens to the data?
Partner nonprofit organizations, local governments, and communities use EQI’s data for watershed planning, allocating staff time and resources, and justifying funding requests for restoration and conservation efforts. Frequent and widespread monitoring helps identify sudden water quality changes and long-term trends. Results are also used for youth education and community involvement. Our ultimate priority is supporting local solutions to improve water quality in western NC.
