Why should you treat your water supply?
All water supplies have certain levels of chemical contaminants (e.g. DBCP, EDB, TCE, PCE, THM) and other organic chemicals. Solids such as dirt, rush and lime may also be present, as well as dissolved solids such as calcium, iron and copper. Water quality can vary greatly according to location, water source, time of year, construction within the vicinity, road construction in the area, water main work in the area, fire department testing hydrants and changing municipal water treatment practices.
