** The category of VOC (Volatile Organic Chemical) includes a number of chemicals that are both man-made and naturally occurring. Water from wells and utilities may contain some of these contaminants. Some VOCs are pesticides, herbicides, or insecticides that seep into the ground water after application. Other VOCs enter the water supply through industrial or other waste disposal. This category also includes total trihalomethanes, which are a by-product of chlorination.
A VOC reduction claim by the manufacturer means the system reduces the concentration of all of the following contaminants:
alachlor endrin simazine atrazine ethylbenzene styrene benzene ethylene dibromide (EDB) 1,1,2,2-tetrachloroethane carbofuran haloacetonitriles tetrachloroethylene carbon tetrachloride bromochloroacetonitrile toluene chlorobenzene dibromoacetonitrile 2,4,5-TP(silvex) chloropicrin dichloroacetonitrile tribromoacetic acid 2,4-D trichloroacetonitrile 1,2,4-trichlorobenzene dibromochloropropane (DBCP) haloketones 1,1,1-trichloroethane o-dichlorobenzene 1,1-dichloro-2-propanone 1,1,2-trichloroethane p-dichlorobenzene 1,1,1-trichloro-2-propanone trichloroethylene 1,2-dichloroethane heptachlor trihalomethanes (TTHM) 1,1-dichloroethylene heptachlor epoxide bromodichloromethane cis-1,2-dichloroethylene hexachlorobutadiene bromoform trans-1,2-dichloroethylene hexachlorocyclopentadiene chlorodibromomethane 1,2-dichloropropane lindane chloroform cis-1,3-dichloropropylene methoxychlor xylenes dinoseb pentachlorophenol
