1929 and 1950, mercury was used by DuPont Co. in Waynesboro as a catalyst in fiber production. During that time, strict storage and disposal regulations did not exist, and mercury made its way into the South River. A serious contamination problem was discovered in the 1970s. Other riverside industries such as Crompton-Shenandoah also discharged pollutants into the river during a time of less stringent environmental regulations. The most notable example was the bright dyes the Crompton plant used to finish woven fabric.
More recently, other primary pollutants include phosphorous, sediments, and bacteria. These pollutants can be identified from failing septic systems, urban runoff, animal waste, and streambank erosion. These types of pollutants stress aquatic life, including insects and game fish, and can accelerate algae growth.
Rebound of the River
In November 2000, DuPont agreed to establish an interdisciplinary team to research the issue of mercury contamination and its consequences. This group is called the South River Science Team. Through their ongoing efforts, better understanding of the river and its water quality has improved. The public is also properly informed of risks associated with eating contaminated fish.
The presence of local springs make the watershed a unique resource with potential for eastern brook trout habitat restoration.

In 2011, Trout Unlimited and the VDGIF opened a 4 ½ mile stretch of the river as a public fishery stocked with brown trout.
Flood History
One hazard of living in a city with a river is flooding. River floods occur when heavy rains fall over a large area of the watershed. Historical flood crests are shown below.
