About Water
Water can be considered a universal solvent. As it passes from liquid to vapor and back again to liquid in its natural cycle, it has a tendency to dissolve everything it touches.
In the air, water vapor can mix with sulfur from smokestacks, forming an acid which will eventually fall back to earth as rain, sleet, hail or snow.
As water passes through the surface of the earth to the water tables below, it dissolves minerals and other substances it may encounter, including PCBs, bacteria, fertilizers and insecticides.
Even after reaching a home, water can continue to dissolve such things as lead from the solder in plumbing pipes. An effective water filtration system is recommended for any home.
