WICHITA, Kansas — About 150,000 people in Kansas get their drinking water from private wells.

How clean, and safe, is that water? Short answer: It depends.

But new research suggests those wells deliver water tainted with a range of pollutants. Some leaked from dry cleaning operations. Yet far more wells soak up, and deliver to taps, fertilizer that’s been building up in Kansas soil and water over generations of modern farming.
