Water pollution is a big problem around the United States. By some estimates, there are as many as 73 different types of pesticides that have been found in ground and surface water. These usually find their way into the drinking water supply. In addition to that, experts have found that more than two-thirds of the estuaries and bays in the country have been degraded due to pollution from phosphorous and nitrogen. To make matters worse, new research has shown that about 47% of American lakes, 45% of streams, and 32% of bays are currently polluted. The good news is that many things can be done by people at home and businesses to protect and improve groundwater and surface water quality.
