Whole House Arsenic Removal System (Non-Backwashing, No Electricity)

Whole-house arsenic removal system for private well water. WQA Gold Seal certified arsenic-selective ion exchange resin reduces arsenic below the EPA 10 ppb limit at every tap, in a non-backwashing tank: no salt, no drain, no electricity, no valve to program. One size covers most homes at up to 10 GPM service flow. Whole House Arsenic Removal System: Non-Backwashing, No Salt, No Electricity, No Drain Line A whole-house arsenic removal system for private well water that uses WQA Gold Seal certified arsenic-selective ion exchange resin to reduce arsenic below the EPA Maximum Contaminant Level of 10 parts per billion. This is the same resin class municipal utilities and licensed water treatment dealers install for arsenic: the manufacturer's spec sheet rates it at roughly 500,000 gallons per cubic foot reducing 50 ppb arsenic to under 10 ppb, and an annual lab test of your treated water confirms it is doing its job in your home, not just on paper. The resin absorbs arsenic permanently into the bead, so the system never backwashes, never regenerates, and never needs salt. It is the same tank-and-head architecture as our non-backwashing whole house carbon filter: a 12 inch by 54 inch black Vortech mineral tank with a Clack C1190 in/out service head and a Clack stainless bypass. Plumb it in and it works. Earlier versions of this system shipped with a metering valve. That valve never backwashed anything; it only counted gallons as a service reminder. The media itself has always worked the same way: it absorbs arsenic until it reaches capacity, and the right way to track media life is an annual certified lab test of the treated water, not a valve. Removing the valve, drain line, and electrical requirement makes the system simpler, more reliable, and easier to install, with nothing lost in arsenic performance. Best For, Not For Best for: private well water tested above 5 parts per billion total arsenic (the EPA Maximum Contaminant Level is 10 ppb; many state health departments recommend treating above 5 ppb, especially with young children in the household), in well water that is already at neutral pH (6.5 to 8.5) with iron below 0.3 ppm, in arsenic-prone geology including New England (Maine, New Hampshire, Vermont, Massachusetts), the Upper Midwest (Michigan, Wisconsin, Minnesota), the Southwest United States (Arizona, Nevada, New Mexico, parts of California), Appalachia, and parts of the Pacific Northwest. Best for homeowners who want a one-time install with no controller programming, no salt refills, no scheduled backwash, no electrical outlet at the install location, and no plumbed drain. Up to 10 GPM continuous service flow covers most homes. Not for: water with iron above 0.3 ppm or manganese above 0.05 ppm; pre-treat with an iron filter first because iron will foul the arsenic resin and shorten media life dramatically. Not for water with elevated phosphate, silica, sulfate, selenium, or vanadium without a water test review, since these competing anions reduce arsenic capacity. Not for municipal water on a public water system. Talk to Aidan Before You Buy Free expert phone consultation before you buy. Call or text Aidan at 800-460-5810, 7 days a week, 8 AM to 5 PM Eastern.

Why Arsenic-Selective Ion Exchange Resin Matters Most low-cost whole-house arsenic filters use granular adsorptive media, typically titanium dioxide or iron oxide coated alumina. They physically trap arsenic on the surface of each granule. They are inexpensive and they work, but they have one serious flaw: when the adsorptive bed reaches capacity, accumulated arsenic can desorb and "dump" back into the treated water at concentrations higher than the source water. An arsenic dumping event between annual tests means your family is drinking water with elevated arsenic without knowing it. WQA Gold Seal arsenic-selective hybrid ion exchange resin is structurally different. The resin is a polymer matrix with hydrated iron oxide monoatomically dispersed throughout the bead, not just coated on the surface. Even when operated past its exhaustion point, effluent arsenic levels never exceed influent arsenic levels. There is no arsenic dumping. That single property is why we put this resin in every arsenic system we ship, and why we chose it over cheaper titanium dioxide and iron oxide alumina alternatives that competing whole-house arsenic systems use. Treatment Order for Wells with Iron and Arsenic If your well water has both iron and arsenic, the install order is fixed: iron filter first, then water softener if hardness is elevated, then arsenic filter last. The water reaching the arsenic resin must be effectively iron-free (under 0.3 ppm) because residual iron will coat the resin beads and reduce arsenic exchange capacity. Aidan walks customers through this sequencing on every consultation call. If your iron is above 5 ppm, our Katalox Light catalytic iron filters will also remove some arsenic as a coprecipitant, but for arsenic above the EPA MCL we always recommend a dedicated arsenic-selective resin downstream as the polishing step. Numbered Features Reduces arsenic from elevated well water to below the EPA MCL of 10 parts per billion using WQA Gold Seal certified arsenic-selective hybrid ion exchange resin, with capacity of approximately 500,000 gallons per cubic foot reducing 50 ppb to under 10 ppb under ideal conditions, approximately 1,000,000 gallons total system capacity. Zero arsenic dumping at media exhaustion. Unlike titanium dioxide or iron oxide alumina adsorptive media, effluent arsenic level never exceeds influent arsenic level even past the resin's working capacity, the safest property a residential whole-house arsenic media can have. Installs anywhere with pressurized water. No electrical outlet required, no floor drain required, no salt, no backwash cycles, no controller programming, no scheduled service intervention. Built for any home, including cabins, off-grid homes, well houses, and basements without drains.

The manufacturer's specification sheet notes the resin also reduces uranium and certain other trace-level contaminants. Does not remove iron, manganese, hardness, hydrogen sulfide (rotten egg smell), chlorine, sediment, bacteria, viruses, lead, copper, mercury, nitrate, fluoride, or volatile organic compounds; pair with the appropriate dedicated treatment if any of those are present in your well water. Installation Overview Plumbed inline on the cold water service entering the home, downstream of the well pressure tank and downstream of any iron filter or water softener. The 1 inch threaded inlet and outlet on the Clack bypass fit standard residential plumbing; reduce to 3/4 inch with a standard threaded adapter if needed. No electrical outlet at the install location, no floor drain, no brine line, no programming. The system arrives with the head and bypass mounted; the 2 cubic feet of arsenic-selective resin ships boxed and is loaded at install. A licensed plumber typically installs it in 1 to 2 hours. Water Testing and Media Life Arsenic is invisible, tasteless, and odorless, so the only way to know what your well water contains, and the only way to know when this system's media is approaching capacity, is a certified lab test. Test the raw well water before purchase to confirm arsenic concentration and to check for the upstream conditions (pH, iron, manganese, phosphate, silica, sulfate). Then test the treated water annually after install. Resin life depends on raw arsenic concentration and total volume of water treated: 1 to 5 years is the typical residential range. A well at 30 ppb arsenic with high household water use will exhaust faster than a well at 12 ppb arsenic with normal use. When the treated water arsenic begins to climb (still below the influent level thanks to no-dumping resin chemistry), the tank gets a media rebed with two boxes of ASM-10-HP arsenic-selective resin and the tank, head, and bypass continue in service.

Frequently Asked Questions for the ML Pipeline Does this arsenic system need salt or backwashing? No. Arsenic-selective ion exchange resin absorbs arsenic permanently into the resin bead. There is nothing to flush to a drain and the resin is not regenerated with salt. Earlier metered versions of this system used a valve only to count gallons as a service reminder; the valve never backwashed the media. This build removes the valve entirely: no salt, no drain, no electricity, no programming. What is the EPA limit for arsenic in drinking water? The EPA Maximum Contaminant Level for arsenic in public drinking water is 0.010 mg/L, equivalent to 10 parts per billion (ppb). Many state health departments and pediatric guidance recommend treating private well water above 5 ppb arsenic, particularly when young children, pregnant women, or immunocompromised household members are present, because long-term arsenic exposure is linked to skin, bladder, and lung cancer, cardiovascular disease, and developmental effects in children. Where is arsenic in well water common in the United States? Naturally occurring arsenic from bedrock geology is common in private wells across New England (Maine, New Hampshire, Vermont, Massachusetts), the Upper Midwest (Michigan, Wisconsin, Minnesota, parts of the Dakotas), the Southwest United States (Arizona, Nevada, New Mexico, parts of California, parts of Colorado), Appalachia (parts of Pennsylvania, West Virginia, Virginia), and parts of the Pacific Northwest. USGS arsenic-in-groundwater mapping is the best regional reference. Will this system take care of my arsenic problem? Yes, when it is matched to your water, and we verify that match before you buy. Send your certified lab results to Aidan and he confirms the fit at no charge. The resin is the same WQA Gold Seal certified arsenic-selective media professionals install, rated by the manufacturer at roughly 500,000 gallons per cubic foot reducing 50 ppb arsenic to under 10 ppb. After install, a simple annual lab test of your treated water proves the system is holding arsenic below the EPA limit in your home, and even at the end of media life this resin never releases captured arsenic back into your water. If a lab test ever shows otherwise, call us and we will make it right. Why does the water need to be iron-free before the arsenic filter? Iron in the influent water coats the arsenic-selective resin beads and blocks arsenic exchange sites. As little as 0.3 ppm iron will measurably shorten media life. The fix is an upstream iron filter (Katalox Light catalytic iron filter is our standard recommendation) that drops iron below the threshold before the water reaches the arsenic resin. Why this resin and not titanium dioxide or iron oxide alumina? Titanium dioxide and iron oxide coated alumina are common, cheaper adsorptive media for arsenic. They work well until the bed approaches capacity, at which point accumulated arsenic can desorb and release back into the treated water at concentrations higher than the source. Arsenic-selective hybrid ion exchange resin does not exhibit this dumping behavior; effluent arsenic stays below influent arsenic even past exhaustion. In a residential installation tracked by annual testing, the no-dumping property is the most important safety characteristic the media can have. Do I need a water softener with this system? Only if your hardness is elevated and you want softened water for the household. Hardness does not directly compete for arsenic exchange sites the way iron and phosphate do, but a softener installed before the arsenic filter is the standard sequence when both are present. How do I know when to replace the media? Test the treated water arsenic annually. As the resin nears capacity, treated arsenic begins to creep up but stays below the raw influent level. Replace the media when treated arsenic approaches the action threshold for your household (5 ppb if you have small children, 10 ppb otherwise). The rebed is two 1 cubic foot boxes of ASM-10-HP resin; the tank, head, and bypass stay in service. Aidan will help you read the test results. Can I install this myself? Yes. The system arrives with the head and bypass mounted; the resin ships boxed and is loaded at install. There is no drain line, no brine line, and no electrical connection, so the plumbing is simpler than a water softener: cut in the bypass on the main cold line and you are done. A homeowner with basic plumbing skills can install it in 1 to 2 hours, or any local plumber can install it.
