We'll tell you how agricultural compounds may go with the flow on today's EnvironMinute. Nitrates are on the rise in some American water supplies, but the greatest risk is to rural residents who tap into their own wells.
Shallow wells tend to be more affected than deeper ones.
Nitrates in drinking water can be most harmful to infants, but also can cause algae buildup that kills fish and clogs plumbing. Nitrate levels continue to increase in the environment because of various farming practices. A recent study by the U.S. Geological Survey found that nine percent of the home wells sampled had a higher level of nitrates than what's considered safe. Experts say better farm management is the key to reducing nitrates and keeping water clean and safe.
