A2: Weather

Cynthia Sellinger, a hydrologist with National Oceanic and Atmospheric Administration in Ann Arbor, is quoted for a Post-Tribune of Northwest Indiana article on how aging sewer systems are standing up to heavy rains. “Usually in the Great Lakes, the average amount of water that falls per month is two inches. That’s in a whole month. You got more than that in a day or so. In a year you’d get 30 inches. That much really will flush the system like crazy. Agricultural pesticides, nutrients, fertilizer. That goes right into the water.” [Source]
