Pentachlorophenol is a white organic solid with needle-like crystals and a phenolic odor. The greatest use of pentachlorophenol is as a wood preservative (fungicide). Though once widely used as an herbicide, it was banned in 1987 for these and other uses, as well as for any over-the-counter sales. The major source of pentachlorophenol in drinking water is discharge from wood-preserving factories.
Some people who drink water containing pentachlorophenol well in excess of the maximum contaminant level (MCL) for many years could experience problems with their liver or kidneys and may have an increased risk of getting cancer.
MCL ADVISORY - ACTION IS HIGHLY RECOMMENDED
Pentachlorophenollevels were detected in your water sample to exceed the maximum contaminant level (MCL).
ACTION IS OPTIONAL
Pentachlorophenol levels were detected in your water sample but do not exceed the maximum contaminant level.
