Arsenic Removal
for Prescott Wells
Over 40% of private wells in Yavapai and Pinal Counties exceed the EPA’s 10 ppb arsenic limit. Aqua Cat designs arsenic-removal systems tested to non-detectable levels — whole-house adsorption or point-of-use reverse osmosis, sized to your specific water.

How Bad Is Arsenic in Yavapai County Wells?
Arsenic in Northern Arizona groundwater is geological. It leaches from the volcanic and granitic bedrock that underlies most of Yavapai and Pinal Counties, and it shows up in measurable concentrations in a large share of private wells. The numbers are not small.
Peer-reviewed sampling published in Science of the Total Environment and the Arizona Department of Health Services’ Cornville Health Consultation found:
- 40%+ of wells in Yavapai and Pinal Counties exceed the EPA’s 10 ppb maximum contaminant level (MCL).
- Cornville-area wells tested between 15 and 952 µg/L — the high end is 95× the legal limit.
- Areas with historical mining or deep groundwater exploration show clusters of extreme arsenic concentrations.
Arsenic is colorless, odorless, and tasteless. There is no DIY way to detect it — certified lab testing is the only path. Long-term ingestion at levels above 10 ppb is associated with bladder, lung, and skin cancers, cardiovascular disease, and developmental effects in children. The EPA, ATSDR, and World Health Organization all classify it as a Group 1 human carcinogen.
How Aqua Cat Removes Arsenic
There are three proven technologies for residential arsenic removal, and Aqua Cat installs all three depending on what your water test shows:
- Whole-house adsorption media ($4,750 flat installed — The Jaguar Package) — arsenic-selective resin (typically iron-based) captures arsenic V across every tap in the home. Best for homes where every shower, sink, and laundry appliance should run arsenic-free.
- Point-of-use reverse osmosis ($829–$1,250 flat installed) — a 4- or 5-stage RO at the kitchen sink rejects 95+% of arsenic V through the membrane. Most cost-effective for drinking and cooking water if your concern is ingestion only.
- Combined whole-house + RO ($5,579–$6,000 flat installed) — the gold standard for high-arsenic wells. Whole-house adsorption catches the bulk; an under-sink RO provides a second barrier for drinking water.
Arsenic comes in two forms. Anion exchange and reverse osmosis only treat arsenic III after a chemical pre-oxidation step; the Bayoxide E33 adsorption media in the Jaguar Package treats both forms directly, with no pre-oxidation stage to maintain. A retest after installation confirms the system reaches non-detectable levels, and Aqua Cat reads those results with you free.
The Jaguar Package — $4,750 Flat, Installed
A packaged residential arsenic adsorption system from AdEdge Water Technologies — the AdVantEdge Medallion Series POE, running Bayoxide® E33 media. No other technology matches its simplicity: no salt, no chemicals, no additives — just periodic automatic backwashing.
AdVantEdge Medallion POE — LCD control valve with flow totalizer and built-in sample ports
- Treats both arsenic III and arsenic V — no pre-oxidation step, no chemical feed, unlike exchange or RO approaches
- 90–99% typical removal, engineered to bring 5–500 ppb wells under the EPA limit of 10 ppb
- Wastes less than 1% of your water — whole-house RO wastes 25–75%
- Automatic LCD control valve with a flow totalizer that counts gallons treated toward media change — and built-in sample ports for easy testing
- Spent media is non-hazardous (passes EPA TCLP) — no hazardous-waste handling, ever
$4,750 installed — flatSystem + media · licensed installation with loop plumbing · commissioning and startup sample · 2-year labor warranty

| Hardness | <300 mg/L — a softener is optional; if used, it goes before the AdEdge unit |
| Sediment | Pre-filter included in the install where the well needs it |
How It Compares (manufacturer data)

After the install: an annual retest confirms the number, the totalizer tracks gallons toward media change, and the media exchange is flat-quoted when it’s due — no surprises years later. Pair with an under-sink RO system ($829) for gold-standard drinking water on top of whole-house protection.
What Arsenic Removal Costs — Same Price Statewide
Pricing depends entirely on which technology fits your water test and home:
- Under-sink reverse osmosis (drinking water only): $829–$1,250 flat installed
- Whole-house arsenic adsorption: $4,750 flat installed — The Jaguar Package
- Whole-house + under-sink RO (most protection): $5,579–$6,000 flat installed
Every system includes a 2-year labor warranty plus the manufacturer's warranty and a post-install lab confirmation that arsenic is below detection. Annual media replacement on whole-house systems runs $200–$400 depending on usage.

Arsenic Removal Questions
The only way is a certified lab test. Arsenic is colorless, odorless, and tasteless. Peer-reviewed sampling found that over 40% of private wells in Yavapai and Pinal Counties exceed the EPA 10 ppb arsenic limit, with some Cornville-area wells testing up to 952 µg/L. The $185 Premium Water Test, which is SimpleLab's Drinking Water Test: Level 1 + Bacteria ordered directly from the lab, detects arsenic at low ppb levels alongside 52 other parameters.
The EPA Maximum Contaminant Level (MCL) for arsenic in public drinking water is 10 parts per billion (10 µg/L). The World Health Organization recommends the same limit. Many private wells in Yavapai County exceed this, and in Cornville some samples have measured 95× the legal limit. Long-term exposure above 10 ppb is associated with bladder, lung, and skin cancers.
Whole-house arsenic removal in Prescott is $4,750 flat installed — The Jaguar Package, an AdEdge system using iron-based Bayoxide E33 arsenic-selective adsorption media. Point-of-use reverse osmosis (drinking water only) is $829–$1,250 flat. The gold-standard combined approach — whole-house adsorption plus under-sink RO — is $5,579–$6,000 flat. All include a 2-year warranty and post-install lab confirmation.
Yes — a properly installed reverse osmosis system rejects arsenic V at 95+% across the membrane. RO is one of the EPA's listed Best Available Technologies for residential arsenic treatment. For wells with arsenic III, Aqua Cat adds a pre-oxidation stage to convert it to arsenic V before the membrane, since RO membranes don't reject arsenic III as effectively.
Whole-house arsenic adsorption media typically lasts 1 to 3 years depending on water usage and arsenic concentration. A 4-person Prescott household with 20 ppb arsenic usually replaces media every 18 to 24 months at $200 to $400 per replacement. An annual retest confirms the system is still performing before replacement is needed. You order that retest from the lab, and Aqua Cat reads the results with you free.
If your test came back above 10 ppb arsenic, do not drink, cook with, or use it to make ice or coffee until treatment is in place. Bottled or RO-filtered drinking water is the right interim step. Showering and laundry water is generally fine — arsenic is a long-term ingestion risk, not a contact risk. Aqua Cat can install an emergency under-sink RO in a single morning visit while a whole-house system is sized.
Yes — and it changes which technology actually works. Arsenic in well water comes in two forms: arsenic V, which most technologies can grab, and arsenic III, which anion exchange and reverse osmosis can only treat after adding a chemical pre-oxidation step. The Jaguar Package’s Bayoxide E33 adsorption media removes both forms directly — no chlorine feed, no pre-treatment chemicals — with 90–99% typical removal. That’s why the lab test matters: it tells us your arsenic level and chemistry so the system is prescribed, not guessed.
No. The spent Bayoxide E33 media passes the EPA’s TCLP leaching test and is classified as non-hazardous waste — it goes to a standard landfill, with no hazardous-waste handling or fees. The arsenic stays chemically bound to the media instead of being flushed anywhere. Media life depends on your water chemistry and usage; the control valve’s flow totalizer counts every gallon treated, and the annual retest confirms performance, so the media exchange gets scheduled before breakthrough, not after.
