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

35 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 and 7 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

Fall Aquatic Invertebrate Workshop

Stream Monitoring Information Exchange (SMIE)
Date: Saturday, October 5th
Time: 9 am to 4 pm
Location: UNC-Asheville and nearby stream
Cost: FREE [donations gratefully accepted]

We’d love for you to join us on Saturday, October 5th for our Fall Stream Monitoring Workshop. NO EXPERIENCE NECESSARY! EQI and MountainTrue are partnering to hold our biannual aquatic invertebrate training. Trained volunteers can sign up to sample SMIE stream sites in Buncombe, Haywood, Madison, Yancey, Mitchell, Henderson, and Polk Counties during the autumn months. This community science program helps us monitor the health of our regional streams. We bring the gear and you bring your curiosity! Spots are limited.

No Water No Beer Fundraiser

NC One Water’s 2nd Annual
No Water, No Beer Event
Date: Thursday, September 26th

No Water No Beer events were started by the American Water Works Association (AWWA) to promote the value of clean
water. This event aims to connect the folks who provide clean water with the local beer-loving community AND local nonprofits that work to keep our local waters clean.

Benefitting EQI, RiverLink, and Water for People!

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.
