How It Works

Regional homeowner feedback:

A
Adam B.

The status labels made it easy to know what to focus on without panicking.

R
Rakesh M.

Instructions were straightforward and the packaging felt professional. Dropping it at USPS was easy.

B
Brandi B.

The results felt consistent with what I’d expect from my area’s water quality, but with more detail.

K
Marcos S.

Seeing the value and units for each analyte made it feel legitimate. Better than a $50 strip kit for sure.

B
Nick L.

Lead was the reason I did it. I appreciated how clearly it was reported. Cheaper than other mail-in kits.

Z
Zach J.

The sample bottle and container were solid. No leaks, no mess.

Y
Yolanda P.

The report was clear and informative. I liked seeing the guideline comparison.

R
Rick K.

Turnaround was faster than I expected after it arrived. The email report was easy to share with my partner.

8 key markers screened

The screening establishes a baseline across important household water-quality markers, including Lead, Nitrate, and Fluoride.

Available in select areas

Eligibility depends on your location and current program availability.

Some additional information

Why is the screening offered at no cost?

For qualifying households in select areas, the laboratory screening fee is sponsored through a broader residential water-quality mapping effort.

This means eligible households may request a mail-in kit without paying the lab analysis fee. Return postage of $10.25 is not included.

Availability depends on your area and current program participation.

When is my analysis result profile released?

Once your sample enters our lab, the analytical screening is completed within 3 to 5 business days.

You will receive a secure Informational Profile that baselines every analyte against environmental benchmarks and infrastructure-resilience standards.

What is included in the lab analysis?

Our analysis goes beyond basic surface tests. We screen for critical factors including Lead, Iron, Fluoride, Nitrate, Manganese, Hardness, and Total Dissolved Solids (TDS).

These insights help you understand exactly what is in your water and how it interacts with your household wellness.

How are sub-optimal findings addressed?

We hope your results show your water is within reference guidelines. However, if contaminants are detected, we provide a clear action plan.

As part of our testing service, we match you with a vetted technical advisor from our network who understands your specific water type and can help to optimize your household water profile.
