        Water Quality Basics

        Water is one of our planet’s most important natural resources. There is the same amount of water on earth now as there was when the earth was formed and there will never be any more or any less.  Most of the world’s water supply, 97 percent, is saltwater in the oceans and is unusable for our daily needs. Another 2 percent is frozen in ice caps and glaciers, leaving just 1 percent of the planet’s entire water supply in the world’s rivers, lakes, and groundwater to meet everyone’s water needs. Many of those rivers, lakes and groundwater sources are endangered by pollutants. From dirt to toxic chemicals, pollutants in our waterways are threatening our health, and the health of the environment and every community’s water quality problems are unique. Simply understanding the role each piece plays isn’t enough.
