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. In a non-monitored installation like a cabin or off-grid home where you are tracking media life by periodic water testing rather than a metered alarm, an arsenic dumping event between tests means your family is drinking water with elevated arsenic without knowing it.\u003c\/p\u003e\n\n\u003cp\u003eWQA 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.\u003c\/p\u003e\n\n\u003ch3\u003eTreatment Order for Wells with Iron and Arsenic\u003c\/h3\u003e\n\n\u003cp\u003eIf 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.\u003c\/p\u003e\n\n\u003ch3\u003eNumbered Features\u003c\/h3\u003e\n\n\u003col\u003e\n\u003cli\u003e\n\u003cstrong\u003eReduces arsenate (As V) from elevated well water to below the EPA MCL of 10 parts per billion\u003c\/strong\u003e 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.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eZero arsenic dumping at media exhaustion.\u003c\/strong\u003e 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.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstalls anywhere with pressurized water.\u003c\/strong\u003e No electrical outlet required, no floor drain required, no backwash cycles, no controller programming, no scheduled service intervention.

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 well below the influent level thanks to no-dumping resin chemistry), the resin tank gets a media swap and the rest of the system continues for the life of the tank and valve.\u003c\/p\u003e\n\n\u003ch3\u003eWarranty and Ongoing Support\u003c\/h3\u003e\n\n\u003cp\u003e10 years on the Vortech mineral tank, 5 years on the Clack C1190 in\/out service head, and lifetime free phone and text support from Aidan at 800-460-5810, 7 days a week, for installation questions, water test interpretation, sizing changes, and media replacement timing.

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.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhere is arsenic in well water common in the United States?\u003c\/strong\u003e 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.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat is the difference between arsenate and arsenite?\u003c\/strong\u003e Arsenate (As V), pentavalent arsenic, is the dominant form of arsenic in oxygenated groundwater and the form most well water arsenic is already in. Arsenic-selective ion exchange resin removes arsenate efficiently. Arsenite (As III), trivalent arsenic, is more toxic and more mobile and is found in some reducing-environment wells. Arsenite must be oxidized to arsenate (via chlorination, ozonation, or an oxidizing filter) for selective resin to remove it. A speciation lab test confirms which forms are in your water.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhy does the water need to be iron-free before the arsenic filter?\u003c\/strong\u003e 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.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhy this resin and not titanium dioxide or iron oxide alumina?\u003c\/strong\u003e 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. For non-monitored residential installations like cabins, off-grid homes, and well houses where you cannot watch a metered alarm, the no-dumping property is the most important safety characteristic the media can have.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDo I need a water softener with this system?\u003c\/strong\u003e 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.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow do I know when to replace the media?\u003c\/strong\u003e 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). Aidan will help you read the test results.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I install this myself?\u003c\/strong\u003e Yes.

Trivalent arsenite (As III) only after upstream oxidation to As V. Some incidental reduction of selenium, antimony, vanadium, and chromium VI may occur depending on raw water chemistry, though this resin is purpose-built for arsenic and is not a multi-contaminant heavy-metal filter. Removal does not degrade with normal exposure to chlorides, bicarbonates, or sulfates at typical well-water concentrations.\u003c\/p\u003e\n\n\u003ch3\u003eHow it works\u003c\/h3\u003e\n\n\u003cp\u003eRaw well water enters the 13 inch by 54 inch Vortech mineral tank through the 1 inch metered control valve and flows downward through 2 cubic feet of WQA Gold Seal arsenic-selective ion exchange resin. The resin contains hydrated iron oxide monoatomically dispersed throughout an anion exchange polymer matrix. Arsenate ions in the water are selectively bound by the iron oxide sites and held in the resin. Treated water exits through the underbed distributor and on to the home. The control valve continuously meters gallons treated and triggers a programmable service reminder when capacity is approaching, prompting a treated-water arsenic test to confirm the resin still meets the 10 ppb MCL. Unlike granular adsorptive arsenic media, the resin does not release accumulated arsenic when capacity is exceeded, so effluent levels never exceed influent levels even past exhaustion.\u003c\/p\u003e\n\n\u003ch3\u003eInstallation overview\u003c\/h3\u003e\n\n\u003cp\u003eThis system installs at the point where the main water line enters the home, typically near the end of the well water treatment train. Recommended treatment order: sediment pre-filter, then iron filter (if iron is present), then acid neutralizer (if pH is below 6.5), then water softener (if hardness is elevated), then this arsenic removal system, then UV disinfection (if bacteria are a concern), then drinking water reverse osmosis at the kitchen sink. Sediment, iron, and pH adjustment all impact arsenic resin capacity, so removing them upstream protects the more expensive arsenic media.\u003c\/p\u003e\n\n\u003cp\u003eThe plumbing connection is 1 inch threaded inlet and outlet with the included bypass valve. You will need a nearby drain (floor drain, utility sink, sump, or condensate pump), a standard 110 to 120 volt grounded outlet within reach of the valve, and basic copper, PEX, CPVC, or SharkBite plumbing supplies. Most experienced DIYers complete the installation in 2 to 3 hours; a licensed local plumber typically charges 500 to 1,000 dollars for the install. The tank ships pre-loaded with media so there is nothing to fill on site in the standard install.\u003c\/p\u003e\n\n\u003ch3\u003eTest first, buy right\u003c\/h3\u003e\n\n\u003cp\u003eArsenic is invisible, tasteless, and odorless. The only way to know what is in your well water is a certified lab test that measures arsenic at parts-per-billion precision and ideally also reports the arsenate vs arsenite speciation (As V vs As III). Before ordering, we strongly recommend a \u003ca href=\"\/products\/well-water-test-kit\"\u003ewell water test kit\u003c\/a\u003e that measures arsenic alongside 52 other contaminants.

We have shipped this exact resin to homeowners with verified well-water arsenic levels across the United States. The very small number of cases where it has not met the target are usually unaddressed arsenite (As III), iron interference, very high silica or competing anions, or a household demand that should have been a lead and lag pair from the start. Aidan will troubleshoot directly with you to confirm the cause before any return is processed.\u003c\/p\u003e\n\n\u003ch3\u003eFrequently asked questions\u003c\/h3\u003e\n\n\u003cp\u003e\u003cstrong\u003eWill the 10 GPM metered system handle my arsenic level?\u003c\/strong\u003e If your certified lab water test shows arsenate (As V) up to roughly 50 ppb, household demand at 10 GPM service flow, influent pH between 6.5 and 8.5, iron below 0.3 ppm, and low competing anions, yes. If raw arsenic is above 30 ppb or you want belt-and-suspenders protection, a lead and lag pair is the right answer. If raw arsenic is below 5 ppb, a less expensive non-backwashing setup or even a point-of-use arsenic RO system at the kitchen sink may be sufficient. Call 800-460-5810 with your test results and we will tell you which configuration is correct.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow is this different from the non-backwashing Clack arsenic filter?\u003c\/strong\u003e Both use the same 2 cubic feet of WQA Gold Seal arsenic-selective ion exchange resin and remove arsenate to the same effluent quality. The differences are operational: this 10 GPM system uses a 13 inch by 54 inch Vortech tank with a 1 inch metered control valve that requires a 110 volt outlet and a drain line, and it carries a higher service flow rating sized for 4 or more bathroom homes with 5 or more occupants. The Clack non-backwashing version uses a 12 inch by 52 inch Vortech tank with a Clack C1190 in\/out head that requires no power and no drain, sized for 2 to 3 bathroom homes, cabins, off-grid setups, and any install location where running power and a drain is not practical. Same media, different valve and tank, different install requirements, different price point.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat is a lead and lag setup and do I need one?\u003c\/strong\u003e Lead and lag means two arsenic systems plumbed in series. The lead vessel does the bulk of the arsenic removal. The lag vessel polishes the water and guards against breakthrough if the lead resin is exhausted before the homeowner notices. When the lead resin is exhausted, swap positions: the old lag (still mostly fresh) becomes the new lead, and the old lead vessel gets new media. This setup gives uninterrupted protection and maximizes media utilization. We recommend it when raw arsenic exceeds 30 ppb, when the family is medically sensitive (pregnancy, infants, immunocompromised), or when the cost of a brief breakthrough event would be unacceptable. Call us to discuss whether your situation justifies it.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat is arsenate vs arsenite, and why does it matter?\u003c\/strong\u003e Arsenic in well water exists in two main forms. Arsenate (As V) is the oxidized form and is what arsenic-selective ion exchange resin removes. Arsenite (As III) is the reduced form, more common in deeper anoxic wells, and is not effectively removed by this resin until it is oxidized to As V. Most US well water has arsenic predominantly as As V, but a certified lab speciation report is the only way to know for sure. If your test shows significant As III, you will need an upstream chlorination, ozonation, or oxidizing filter (potassium permanganate or proprietary catalytic media) to convert it to As V before this system can remove it.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhy does iron need to be removed first?\u003c\/strong\u003e Iron above 0.3 ppm fouls the arsenic resin by coating the active sites and dramatically reducing its capacity for arsenate. Manganese above 0.05 ppm causes similar fouling. Always install an iron filter upstream of an arsenic system if your water test shows meaningful iron or manganese. The iron filter not only protects the more expensive arsenic resin but also addresses staining, taste, and odor problems independent of arsenic.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow often does the resin need to be replaced?\u003c\/strong\u003e Typical media life is 1 to 5 years depending on raw arsenic concentration, daily water use, and competing contaminants. The metered control valve gives a programmable signal when scheduled replacement is approaching, but the only way to know the resin is still meeting the 10 ppb effluent target is annual treated-water lab testing. We recommend testing every 12 months and again whenever the meter triggers the service reminder.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I install this myself?\u003c\/strong\u003e Yes, if you have basic plumbing experience (sweating copper, working with PEX or SharkBite fittings, running a 1\/2 inch drain line, terminating a 110 volt outlet). Most DIY installs take 2 to 3 hours. If you would rather hire a local plumber, expect 500 to 1,000 dollars for the install.
