NORIT GAC 400 PLUS activated carbon – a n acid washed steam activated reagglomerated bituminous granular carbon for well water and point-of-entry systems HYDRODARCO ® 4000 activated carbon – a highly mesoporous acid washed steam activated lignite granular carbon for surface, well water, and point-of-entry systems Coyne’s supplier, Cabot NORIT ® Activated Carbon, has recently conducted studies showing several of their products have enhanced removal capabilities over other carbons. The most common method is activated carbon adsorption.
Presently, limits have been set at 70 ppt (parts per trillion) for potable water but some states are legislating stricter limits.
In addition, the EPA has issued a health advisory while it pursues additional studies. The EPA has recognized PFASs as potential cause of human health effects, especially during pregnancy and in infants. PFASs have been brought to the forefront in recent years as suspected carcinogens and having the ability to accumulate in the body over time with little to no breakdown. PFASs are found in many manufactured products including cookware, clothing, carpeting, essentially products with stain resistant coatings, and most widely known, fire fighting foam. Perfluorooctanoic Acid (PFOA) and Perfluorooctane Sulfate (PFOS) are fluorinated organic chemicals commonly known as perfluoroalkyl substances (PFASs).
