Problems can also originate in your own home. An estimated 20 percent of lead exposure cases are traced to drinking water. The most common source is corroded lead plumbing materials in the household. Lead exposure in adults results in higher blood pressure and hearing difficulties. Children can suffer delayed physical and mental development, anemia, kidney damage and mental retardation.
Pregnant women can face premature birth and reduced birth weight of their babies.
While many are aware of risks like these, the same Water Quality Association survey showed almost 50 percent of respondents want to know more information about the quality of their water and yet one in four doesn't know where to find that information. Less than one in three adults have ever had their water tested for contaminants. Counting the Contaminants It may sound strange, but water isn't to blame for its contamination. That's why all drinking water contains some naturally occurring contaminants. These unavoidable additions are generally not harmful at low levels.
