Researchers at the Columbia Water Center have been analyzing trends in drinking water quality violations. A critical lesson is that water quality violations extend well beyond the problem of lead in Flint’s drinking water.
Across the nation, large-scale water infrastructure such as dams have provided a multitude of services, from electric power and water reservoirs to flood control and containment of pollution.
