Green Riverkeeper Documents Massive Sediment Pollution from World Equestrian Games

As the World Equestrian Games kicked off, our Green Riverkeeper, Gray Jernigan, travelled to White Oak Creek to sample water for turbidity and sediment levels and found evidence of massive water quality violations at the Tryon International Equestrian Center.

Upstream from the Wold Equestrian Center, Gray’s turbidity meter read a relatively clean 13.3 NTU or Nephelometric Turbidity Units – the measure of the concentration of suspended sediment in liquid. The North Carolina sediment standard for water quality is 50 NTU.

Downstream from the Center, Gray’s turbidity meter maxed out at 999 NTU!

This is irresponsible development and illegal pollution. Sediment runoff from construction or other land-disturbing activities is required to be controlled onsite, and if it isn’t it destroys habitat, kills aquatic life and carries along bacteria such as E. coli and other pollutants. We have reported the violations to state officials. We’ll keep you updated as we find out more. To follow the Green Riverkeeper, follow him on Instagram or Facebook.


Western North Carolina is blessed with more than 1.5 million acres of public land, including Nantahala-Pisgah National Forest, Great Smoky Mountains National Park, the Blue Ridge Parkway and several state-owned parks, forests and natural areas. These public lands support the headwaters of our rivers, beautiful mountain vistas, one of the most diverse temperate forests on the planet, and a thriving economy in tourism, crafts and recreation.
During its 30-year history, WNCA (now MountainTrue) has twice prevented logging in the Asheville Watershed, first in 1990 and again in 2004. Eventually the City of Asheville placed a conservation easement over 17,356 acres of the watershed.
