Warning!
Consuming water with combined nitrate/nitrite levels above the USEPA MCL (Maximum Con-
taminant Level) of 10 PPM (10 mg/L) can cause breathing/oxygen absorption problems in in-
fants and animals — and may be linked to certain cancers.
Always install and operate this system according to manufacturer instructions. Test water every
six months to verify proper system operation.
Water Control offers inexpensive, non-certified test services (the first 2 test bottles are included
free with system).
