In the early days of Chemical Valley, the technology to measure and contain air and water pollution was nonexistant. In the late 1960’s and early 1970’s, the discharge of mercury from Dow led to the shutting down of Dow’s plants that used the harmful element. The chemical industries in Sarnia have released contaminants that float down the river, often building up near Walpole Island.

In response to their contributions to the pollution in the area, much of the petrochemical industry in Sarnia banded together to form The Lambton Industrial Society, known today as the Sarnia-Lambton Environmental Association. They worked to alleviate much of the environmental damage done throughout the 20th century.
