Arsenic is a toxic contaminant commonly found at action levels in water supplies of homes in Maine, New Hampshire and the northeast. Arsenic (As) is a naturally occurring contaminant often found in ground water that generally occurs in two forms: pentavalent arsenic (also known as As(V), As(+5), and arsenate) and trivalent arsenic (also known as As(III), As(+3), and arsenate).

Arsenic does not generally impart color, taste, or smell to water; therefore, it can only be detected by an analytical test. Public water supplies are required to monitor their water for arsenic contaminates and to make that information available to the public. Homeowners using private water sources, particularly from aquifers with known or suspected arsenic levels should test their water regularly.

Everclean can design a filtration system to reduce arsenic, both pentavalent and trivalent forms, to concentrations less than 10 μg/L, when applied within the standard water quality parameters recommended by the manufacturer. Moreover, Everclean has successfully developed an effective whole house (point of entry) arsenic treatment system that is priced significantly lower than others on the market and has about 20% of the filter replacement and maintenance costs. Following any installation, Everclean recommends the consumer should have the treated water tested to verify that the desired arsenic reduction is being achieved and continue with routine servicing to ensure the system is functioning properly. Everclean representatives provide for this follow-up testing in systems that Everclean has installed.

Please consult with Everclean Water Treatment Systems for service life expectancy based on specific water quality parameters and testing. When you purchase a system from Everclean Water Treatment Systems you will always receive your replacement filters or media at the lowest cost on the market for life!
