The Jaguar Package

Whole-house arsenic removal for a private well: an AdEdge Medallion tank of Bayoxide E33, an iron-based media that holds arsenic, on a Clack WS1 valve.

• A certified lab test shows arsenic in your well. EPA’s limit for public water is 10 µg/L (parts per billion); private wells are not regulated.
• Your water is inside the media’s limits (see Water it can handle).
• You want every tap treated. For most wells a drinking-water system at the kitchen tap is cheaper and simpler (New Hampshire DES) — the Kitten. New Hampshire’s environmental agency says whole-house treatment is only needed if someone, such as a young child, is likely to drink from a tap other than the treated one. Over 100 ppb of arsenic, it adds, even small amounts swallowed regularly, in the bath or from a bathroom tap, can significantly increase the risk of health effects.

• Soften the water, or remove bacteria, nitrate or PFAS.
• Work as well on arsenic III as on arsenic V: AdEdge says the media works better on arsenic V and recommends pre-oxidation first where a well is all arsenic III.
• Take out all the arsenic. Most systems remove a percentage: the University of Arizona’s example is that removing 90% of 200 ppb still leaves 20.
• Last as long on water with fluoride over 1 ppm, silica, phosphate or iron — they compete for the media (University of Arizona; AdEdge).

Media tank

AdEdge Medallion Series, sized to your home’s peak flow: POE-7-1354 (13″ × 54″, 2.75 cu ft of media, 6–8 gpm) or POE-10-1465 (14″ × 65″, 4 cu ft, 8–10 gpm). Neil’s September 2026 supplier quote was for the POE-10.

Media

Bayoxide E33 from LANXESS: a granular iron-oxide media that holds both forms of arsenic, arsenic III and arsenic V, on its surface.

Control valve

Clack WS1 (AdEdge’s parts list), with a gallon counter for tracking media use and a display that reads CALL after one year as a service reminder (AdEdge’s manual).

Connections

AdEdge V3007 adapters: 1″ elbows with ¼″ sample ports, so raw and treated water can be sampled.

Test kit

AdEdge’s arsenic quick-test kit ships with the system. AdEdge says field kits should be backed by lab results.

Pre-filter

A sediment pre-filter ahead of the tank; AdEdge’s manual calls for a 30-micron one.

• We found no NSF/ANSI 53 listing for the Medallion system or for AdEdge in NSF’s database (checked September 2026). NSF/ANSI 53 is the standard for health claims such as arsenic.
• The E33 media is listed to NSF/ANSI 61 — material safety — with NSF’s note that it is certified for water treatment plants and “has not been evaluated for point of use applications.”
• EPA does not approve or certify treatment devices. AdEdge states its treatment goal as below EPA’s 10 ppb limit; only a lab test of your treated water shows your result.

• AdEdge sizes by flow: the POE-7 for up to 8 gpm, the POE-10 for up to 10 gpm.
• The lab test decides whether E33 suits your water and how long it will last. AdEdge needs arsenic, pH, iron, manganese, hardness, sulfate, phosphate and sulfides at a minimum.
• Contact time (our arithmetic): the POE-10 holds about 30 gallons of media, so about 3 minutes at 10 gpm — LANXESS recommends 3–5. The POE-7 drops under 3 minutes above about 6.9 gpm.

• POE-7: 6–8 gpm, 8 at peak (brochure; the manual says 5–7). POE-10: 8–10 gpm, 10 at peak.
• A flow control fitted inline on the outlet holds it to the peak rating: 8 gpm (green) or 10 gpm (orange), per AdEdge’s manual.
• For scale: a shower head uses up to 2.5 gallons a minute (gpm) and a kitchen faucet up to 2.2 gpm (federal limits, EPA).

• AdEdge’s limits, to check against your lab report:

  AdEdge limits for the Medallion

  In your lab report	Must be
  Arsenic	5–100 ppb (higher with AdEdge’s review)
  pH	5.5–8.5
  Iron	under 0.5 ppm
  Manganese	under 0.05 ppm
  Sulfide	under 0.1 ppm
  Silica	under 30 ppm
  Phosphate	under 0.5 ppm
  Sulfate	under 100 ppm
  Fluoride	under 1.0 ppm
  Hardness	under 300 ppm (about 17.5 grains)
  Tannins	none
  Turbidity (cloudiness)	under 5 NTU

• Pressure 30–125 psi. Temperature 33–100°F in AdEdge’s brochure, 40–110°F in its manual.
• AdEdge says the media works better on arsenic V; where the well is all arsenic III it recommends pre-oxidation first.

• Salt: none.
• Water: each backwash is 14 minutes plus a 2-minute rinse at 7.5 gpm (POE-7) or 10 gpm (POE-10): about 120 or 160 gallons (our arithmetic from AdEdge’s manual). The valve backwashes every 6,000 gallons on the POE-7 and every 10,000–12,000 on the POE-10 (the manual gives both), or every 28 days if that comes first (the manual’s 28-day override). For 2–4 people at 75 gallons a person a day, that is about 2–4% of the water you use, about 130–180 gallons a month (our arithmetic). AdEdge’s own comparison chart puts it under 1%.
• Electricity: a 120-volt outlet that is not on a switch (AdEdge).

• POE-10: 14″ × 65″, shipping weight 230 lb. POE-7: 13″ × 54″, 160 lb (AdEdge).
• A ¾″ rigid drain line that can take the backwash flow (AdEdge).
• An always-on 120-volt outlet.
• Septic: about 130–180 gallons of backwash water a month for 2–4 people (our arithmetic, under What it uses).
• Used-up media passed the EPA leaching tests as non-hazardous; it goes out under local rules (AdEdge).

• None added.

$4,750 installed, flat, anywhere in Yavapai County. Arizona sales tax on the parts is already in that price (CreekWell’s invoice terms). What is not included is listed below.

Not bookable yet. This work costs more than $1,000, which puts it outside what CreekWell can take on until its Arizona contractor licenses are issued. The details here are accurate so you can plan and compare. Why not yet?

Included

• Installation, with the plumbing to connect it where all the house water passes through it
• Commissioning, a startup sample, and a lab retest after installation to confirm the result
• CreekWell’s two-year workmanship warranty

Not included

• The lab test before, and the ongoing treated-water tests after the first retest (see Testing)
• Media replacement when it is used up
• AdEdge’s yearly service visit (see Upkeep)
• Treatment first if your water is outside the limits (iron, hardness, pH, sulfide)
• New loop plumbing if your home has no place to connect it, or code updates — quoted flat and approved by you first
• A drain if none is close enough — quoted first. A new always-on outlet is electrical work, arranged separately

Running costs

• Lab tests: four arsenic tests of the treated water a year on AdEdge’s schedule (SimpleLab’s Total Arsenic test, $60 at its price) and one yearly test of the untreated well water (its Level 1, $155): about $395 a year (our arithmetic).
• AdEdge’s yearly service (see Upkeep): Neil has not published a price for it yet.
• Media: every 2–4 years in AdEdge’s example, 1–3 in New Hampshire’s guidance; about $2,750 for the smaller tank (POE-7) or $4,000 for the larger (POE-10) at New Hampshire’s 2021 figure of about $1,000 a cubic foot (our arithmetic).
• Water: about 130–180 gallons of backwash a month for 2–4 people (our arithmetic). Power: the valve, on an always-on outlet.
• Neil has not published prices for this package’s replacement parts yet; your written estimate lists today’s prices before you approve anything.

Paying

• A 50% deposit sets the install date; the rest is due when it is in and tested.
• The written estimate is good for 30 days. If you cancel after the three business days the FTC’s Cooling-Off Rule gives when you sign at home, what happens to the deposit (for example, parts already ordered for you) is written on the estimate before you sign.
• Zelle, cash or check: no fee. A card fee, if you pay by card, is shown as its own line on the estimate (payment terms).

• AdEdge is now part of Chart Industries, and its website no longer carries Medallion documents. The AdEdge documents under Documents are hosted by others.
• If a part fails, who pays the labor to take it out and fit the new one, in the first two years and after, is written on your estimate.

• Before: a certified lab test is required. Neil checks the report against AdEdge’s list before ordering. SimpleLab’s Level 1 + Bacteria test ($185 at its price) covers arsenic and most of that list, including phosphorus and silica. It does not include sulfide, which AdEdge needs for every well, so you also need SimpleLab’s Hydrogen Sulfide test ($107 at its price): $292 for the two (our arithmetic). Smell is no guide: AdEdge’s limit is 0.1 ppm, and most people smell hydrogen sulfide only from about 0.5 ppm (University of Nebraska).
• After: a startup sample and one lab retest after installation are included. From then on, treated-water arsenic tests at a certified lab — AdEdge says every 3 months; the University of Arizona says at least every year — ordered from SimpleLab at its price, and Neil reads them with you free. The quick-test kit is for checks in between.

• Installed where all the water to the house passes through it.
• No bypass left open: with the bypass open, untreated water reaches every tap. (New Jersey’s environmental agency bars treatment bypasses on arsenic systems at small public water systems.)
• Sample ports for raw and treated water (AdEdge).
• The drain line is run to code with an air gap.
• The City of Prescott has adopted the 2024 International Plumbing Code; the county and other towns set their own.
• If a particular job turns out to need a permit, you are told before any work starts.
