Unimpaired streamflow has long been the benchmark against which current stream flows are evaluated for environmental purposes. The underlying assumption is that if there is water in a stream, the stream must be healthy. A closer look shows why unimpaired flows is often a flawed basis for environmental management, particularly when water quality is the primary problem.
Cross-border water pollution between Tijuana and South San Diego is not new, but in recent years, the problem has grown worse. The reasons are complicated: There is Tijuana’s topography, with its steep hillsides and canyons that drain towards the border; the factories that get away with illegal dumping; the city’s rapid population growth, aging wastewater infrastructure and inadequate garbage collection. In the U.S., funding cuts to the Environmental Protection Agency have prevented improvements to the Borderlands’ sewage system.

Six weeks ago, Hurricane Florence dumped 9 trillion gallons of water across North Carolina. Where exactly does all of it go? As hurricanes move inland, their rainfall swells rivers. Waters rush downstream, collecting waterborne contaminants from flooded out sewage pipes and animal waste from industrial farms. Massive storms like Florence also knock out the power for water pumps, so food, clothes and people go unwashed for days.
