** 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
[Pb] Product also evaluated and determined to possess weighted average lead content of
<=0.25% and complies with lead content requirements for “lead free” plumbing as defined
by California, Vermont, Maryland, and Louisiana state laws and the U.S. Safe Drinking
Water Act.
