What do we know about the “Hydrological Cycle”?

          As water continuously cycles & comes in contact with other matter, it picks up various impurities such as mold, dust, smog, bacteria, smoke, sulfur from industrial smokestacks (acid rain) and carbon dioxide. And you, as customer you can be supplied with one of the two types of waters.

Surface Water and Ground Water: 

Surface Water

          Surface water like, lakes, rivers, reservoirs, can become contaminated with impurities such as nitrates or animal waste from livestock or fungicides, pesticides and herbicides. From industry it can pick up things like arsenic and detergents.

Ground Water

        Ground water int the other hand, is water that has percolated down through different layers of earth like clay, limestone and shale picking up impurities such as radioactivity, sodium, iron, calcium, magnesium and hydrogen sulfide.
