STEP 01
Collect your water
Fill the test tube provided, or a clean container. The tube is sized so the whole strip can go under.
16 essential water safety
checks.
Clear water can still carry things worth knowing about, like lead from older pipes or nitrate in a well. Aquanox-16 checks 16 of them in 30 seconds, right at the tap. If anything reads high, you’ll know exactly what to do next.

THE TEST
A clear answer, at home.
FSH is the hormone that rises as your body moves through menopause. This test reads it — so the changes you've been feeling have something measurable behind them.

Practical guidance
Easy to use.
Easy to understand.
Everything you need to take the test, understand the result, and know what to do next.
Lead (Pb)
EPA action level 0.015 ppm (15 ppb)
What it means
Lead has no taste, colour or smell, so a strip is the only way to spot it at home. It usually enters water from old pipes and solder rather than from the supply itself.
What it doesn't mean
A screening strip isn't a laboratory measurement. It tells you whether lead is worth investigating, not how much is there.
What to do next
A reading at or above the action level should be confirmed by a certified lab before you act on it.
Copper (Cu)
EPA action level 1.3 ppm
What it means
Copper generally comes from household plumbing. Water that's been sitting in pipes overnight picks up more of it.
What it doesn't mean
One high reading from a first-draw sample isn't the same as your supply being affected.
What to do next
Run the tap for a minute and retest. If it stays high, have a certified lab confirm it.
Nitrate (NO₃⁻)
EPA limit 10 ppm
What it means
Nitrate usually comes from fertiliser run-off or septic systems, which makes it more common in well water than in treated supplies.
What it doesn't mean
The strip screens. It doesn't measure precisely enough to make decisions about infant feeding on its own.
What to do next
A reading at or above the limit needs a certified lab test, particularly if there's a baby in the house.
Nitrite (NO₂⁻)
EPA limit 1 ppm
What it means
Nitrite comes from the same sources as nitrate, and the EPA limit is ten times tighter.
What it doesn't mean
A negative on this pad doesn't mean nitrate is clear too. They're separate readings.
What to do next
Read it alongside nitrate, and confirm anything at or above the limit with a lab.
Free chlorine (Cl₂)
EPA limit 4.0 ppm
What it means
Chlorine is added deliberately to keep treated water safe, so finding some is expected rather than alarming.
What it doesn't mean
A low or zero reading isn't automatically good news — on a treated supply it can mean the disinfectant has dissipated.
What to do next
If it reads above the limit, contact your water authority rather than a lab.
Total hardness (GH)
No federal limit · under 150 ppm recommended
What it means
Dissolved calcium and magnesium. Hard water leaves scale on kettles and taps and can make soap harder to rinse.
What it doesn't mean
Hardness isn't a health hazard. It affects plumbing and how water feels, not whether it's safe.
What to do next
Nothing health-related to do. A high reading is useful if you're deciding about a softener.
Total alkalinity
No federal limit · 75 – 150 ppm recommended
What it means
How well your water resists changes in pH. Adequate alkalinity helps keep water from turning corrosive to pipes.
What it doesn't mean
This isn't a contaminant reading. It describes the water's chemistry rather than anything in it.
What to do next
Read it next to pH. Low alkalinity with low pH is the combination worth looking at.
Mercury (Hg)
EPA guideline 0.002 ppm
What it means
Mercury in drinking water is uncommon and usually traces back to industrial discharge or natural deposits near the source.
What it doesn't mean
A screening strip at this concentration is a rough instrument. Treat any positive as a prompt, not a measurement.
What to do next
Any reading at or above the guideline should go straight to a certified lab.
Zinc (Zn)
EPA guideline 5.0 ppm
What it means
Zinc usually comes from galvanised plumbing. The guideline is about taste rather than safety.
What it doesn't mean
A reading above the guideline isn't a health limit — it's the point where water starts tasting metallic.
What to do next
If taste is the issue, running the tap before drawing water often helps.
Fluoride (F⁻)
EPA 4.0 ppm limit · 2.0 ppm secondary recommendation
What it means
Fluoride occurs naturally in some groundwater and is added deliberately to many treated supplies. This parameter has two reference points rather than one.
What it doesn't mean
Finding fluoride isn't a fault. On a treated supply it's expected.
What to do next
If it reads above 4.0 ppm, contact your water authority.
pH
EPA guideline 6.5 – 8.5
What it means
How acidic or alkaline your water is, on a scale where 7 sits in the middle. Local geology sets it, and so do the chemicals a treatment plant adds.
What it doesn't mean
pH isn't a contaminant reading. It describes the water itself rather than anything dissolved in it.
What to do next
Low pH corrodes pipes and pulls metals into the water. High pH causes scaling and a bitter taste. Read it next to total alkalinity — low on both is the combination that matters.
Hydrogen sulfide (H₂S)
No formal limit · 0 ppm recommended
What it means
The rotten-egg smell. It's a gas dissolved in the water, usually from underground deposits or from organic matter breaking down.
What it doesn't mean
At low levels it isn't typically harmful. This one is unpleasant rather than dangerous.
What to do next
It corrodes plumbing over time, so it's worth dealing with even though there's no health limit behind it. A water treatment specialist is the right call.
Iron (Fe)
EPA guideline 0.3 ppm
What it means
A naturally occurring metal, and the usual cause of rust-tinted water and stained laundry. It comes from corroding iron pipes or from the ground itself.
What it doesn't mean
Generally not harmful at low levels. This is a taste and staining guideline, not a health limit.
What to do next
Persistently high iron is a filtration question rather than a medical one.
Manganese (Mn)
EPA guideline 0.05 ppm
What it means
Often found alongside iron. At low levels it's a taste and staining issue, but the reference guide notes that at high concentrations manganese can affect neurological development, particularly in infants.
What it doesn't mean
Finding some isn't unusual in groundwater, and the EPA figure is a quality guideline rather than an enforceable health limit.
What to do next
Above the guideline is worth a certified lab test, especially if there's a baby in the house.
Sulfate (SO₄²⁻)
EPA guideline 250 ppm
What it means
A mineral that occurs naturally in water, from eroding deposits, industrial discharge or agricultural run-off.
What it doesn't mean
It isn't a health limit. The guideline is about taste.
What to do next
High levels taste bitter and can have a laxative effect in large amounts. Worth knowing if you've moved and the water tastes different.
Sodium chloride
No formal limit · 20 – 200 ppm recommended
What it means
Common salt, naturally present in small amounts. Road salt run-off, industrial pollution and sewage contamination all push it up.
What it doesn't mean
A salty taste isn't automatically a safety problem, and there's no enforceable limit behind this one.
What to do next
High levels corrode plumbing and add to dietary sodium. Worth mentioning to a doctor if you're on a sodium-restricted diet.

Works great. Just be careful of your timings when you use the test strip. I love that they included a "test tube" that's the perfect size for a test strip. Saved me having to search for a deep enough container.
Barbara T.
Verified Buyer
I wanted to test the water for all of the faucets in my house. This was great and so easy to use and see the results. Definitely do recommend
Ronnette

Very easy to use. Easy to read test strip. Quick results. I'd buy again.
Franklin P.
Verified Buyer
Great peace of mind and easy to use. The only negative thing I could say is that it's very light, so my wife thought there was nothing left in the box and threw it out with 6 tests left. So I will be buying it again to do more tests.
