Long range water quality data is essential to the protection of our water resources. The Volunteer Water Information Network (VWIN) is a cooperative effort among several organizations in Western North Carolina to monitor chemical properties of streams throughout the region. ECO began monitoring 18 sites in 1992 and has since expanded to 33 sites in Henderson County.
Volunteers collect water samples from each site monthly. The samples are sent to an independent lab to be evaluated for eleven chemical parameters: pH, conductivity, alkalinity, turbidity, total suspended solids, copper, zinc, lead, orthophosphate, ammonia nitrogen and nitrate nitrogen. This provides a valuable database of water quality information to monitor trends and the effects of changing land use on our waterways. VWIN data is analyzed to create an annual report on the water quality for Henderson County. The VWIN program has created an objective dataset covering nearly two decades, allowing ECO to identify streams facing degradation and obtain financial and political resources to protect streams in Henderson County. VWIN volunteers use this WQ Survey Sheet to collect visual data during sampling in the fall of each year.
Through the VWIN program ECO has identified waterways of pristine quality and detected highly degraded streams in Henderson County.
NEW! VWIN Site Sponsorship Program
With continuing budget cuts it is now more important than ever for community members and organizations to come together to support water quality programs like VWIN. As a VWIN sponsor, you make it possible for streams in our county to continue to be evaluated for problems that affect the health of watersheds, animals, plants and people. Chemical testing for one stream site costs $500 each year. Sponsorship of a site at this level from January through December 2014 will include:
- Quarterly updates on the condition and chemical analysis of your adopted site
- Notifications of opportunities for your group to participate in stream clean-ups and monitoring activities with Adopt-A-Stream and VWIN volunteers
- A copy of the most recent VWIN Annual Report including data analysis on all ECO VWIN sites
- Recognition through ECO publications and events
Additionally, sponsors will receive ECO’s quarterly newsletter which contains our full calendar of events as well as regional and local environmental news. Following receipt of the completed VWIN Sponsorship form found below, ECO will choose a monitored site that best fits each group’s location and interests. Please contact us with any questions at phone number (828) 692-0385 or by email at firstname.lastname@example.org. Join us in protecting and improving Henderson County streams today!
VWIN Success Stories
- ECO’s VWIN data showed the Mills River watershed to be degraded due to high inputs of sediment and nutrients. This led to the establishment of the Mills River Partnership in 1998. The Mills River partnership created a strategic plan for working with landowners to install projects reducing nonpoint source pollution. Thee plan was successful resulting in the restoration of a prime drinking water source in Western North Carolina, trout fishery and recreational area.
- ECO’s VWIN data contributed to the identification of water quality degradation throughout the Mud Creek Watershed due to rural and urban stressors. This led to the Mud Creek Restoration Project. The project is currently active, focusing on stream restoration, urban stormwater management, agricultural best management practices and education.
- The backlog of ECO’s VWIN data demonstrated sediment to be a primary and consistent water quality impairment in Henderson County. This provided strong justification for the approval of an Erosion and Sediment Ordinance in Henderson County.
