Hidden Rivers explores the impact that storm water runoff has on streams, creeks, rivers and on the Chesapeake Bay. Each time it rains, millions of gallons of rainwater pours into subterranean pipes, surface concrete culverts, and ditches. The water and everything in it—chemicals, petroleum products and other pollutants—is drained from paved surfaces into a huge network of pipes that dumps it into streams, rivers, and creeks that feed into the Chesapeake Bay. This extraordinary web-like network of subterranean and unseen manmade rivers also carries an overlooked but major pollutant: sediment. Dirt from roads, parking lots, driveways, construction sites and many other sources all contribute to the pollution of the bay and its many tributaries.
