Water Quality Test

Care to know what you’re drinking (or will be drinking)? The award-winning Tap Score test reports on 40+ contaminants and properties within your water

Four reasons to have HomeKey Inspections test your water:

  1. Lead Contamination: 
    Just an inch of old plumbing causes long-term brain damage, especially in children.

  2. Arsenic is tasteless:
    20% of untreated drinking water in the USA contains cancer-causing arsenic (USGS).

  3. Hidden Maintenance:
    Your biggest investment might come with an expensive headache: water hardness.

  4. Know before you buy:
    Children are especially vulnerable to contaminants in water, and they deserve the best.


Contaminants find their way into water from old pipes, agriculture, industry, and other sources. Often these contaminants have no color, smell or taste. Local authorities will test at some public water facilities, but they don’t know what’s coming out of your faucet, and there’s a lot of pipe between the water treatment facility and your home. Contaminated springs and aquifers can also allow dangerous contaminants to flow to private wells from far away.

HomeKey partners with the only water testing service with unbiased treatment matching and health risk analysis – so you don’t waste money on treatment that doesn’t do what you need.

Your Tap Score report is easy to read, accurate, and actionable.

Understand Your Water

Your Water Quality report starts with a report card for how your water measures up. 

No need to be a Toxicologist

Your TapScore report will make it easy to know which contaminants in your water are harmful to your health. 

Your water’s profile

Even contaminants and properties that don’t have known health effects matter when choosing a water treatment system or uncovering the source of contamination. 

Industry-leading analysis at your fingertips

Contaminants found at or near harmful levels are displayed in the Watch List, along with their common sources, health effects, and other properties. 

Thorough testing

Anything else that’s detected at levels below what is thought to be a health risk is shown further down in the report. 

Custom treatment recommendations

Your report will recommend the products that can help treat the contaminants found in your water. Every report includes support from a water treatment specialist. 

Discover the quality of local water

On a private well? Millions of test results show information about nearby groundwater contamination. Public water supply? View information about your water supply’s compliance history. 

Everything else

All parameters tested for, but not detected in your water sample, shown in your report for your peace of mind and records.
