Water Testing
VOCs, including semi-VOCs, are one of the most important classes of environmental pollutants because of their significant health effects
The source of aqueous VOCs can be as varied as domestic to agricultural to industrial waste
VOCs are one of the three contaminant groups regulated by the EPA Chemical Contaminant Rules, which apply to all public water systems
Potential health risks from these contaminants include cancers, organ damages, circulatory system disorders, nervous system disorders, and reproductive system disorders
To reduce such risks, EPA set a Maximum Contaminant Level (MCL) and an MCL Goal (MCLG) for each contaminant in drinking water
The MCLGs for some VOCs are zero, e.g., benzene, carbon tetrachloride, 1,2-dichloroethane, trichloroethylene, vinyl chloride
Typical MCLs are in the low ppb (ng/mL) or sub-ppb range (EPA, 2009)
