"The report, which only studied the drainage area's makeup in low-water conditions, found excessive nutrients flowing into streams mostly from wastewater treatment plants and industrial discharges.

"In the Conestoga River watershed, there are more than 50 point-source nutrient dischargers permitted to discharge more than 48 million gallons per day," the report noted.

So-called nonpoint sources, such as storm runoff from farms, construction projects and housing developments also are main contributors to the pollution and may, in fact, be the major source when water quality is assessed in normal and high-flow periods, the study indicated."
This makes it sound like most problem comes from the everyday sources, those known dischargers. Total load calculations (reminds me of a load od something else) are years away. I'm sure there will be less discharging permitted in the meantime. Uh, no. It's those damn cows again. Will those routine dischargers be required to reduce flows during low water periods?
Don't even get me started on the failure to clean up toxic waste sites, in the name of financial expediency.
