Point-of-use analysis
Our lab is mapping 8 water quality markers to baseline your home's tap, including Lead, Nitrate, Fluoride, Iron, and Manganese.
Independent results using proven methods.
Measurement integrity is our first priority, to ensure that you have actionable data for informed decision-making.
We've earned your trust
Excellent water quality report! Really appreciate spending so much time explaining everything. Highly recommend them!
An excellent resource in explaining what was in our water and how to potentially remediate. You guys are the best and I hope I helped you as much as your info helped us!
My advisor was very helpful throughout the whole process. He called me and explained in great detail my results and discussed my concerns with me.
I have trust in the results based on the sincerity of the interaction.
Well worth it and would definitely recommend. Now I have some peace of mind.
Getting such a detailed report with clear recommendations AND not having to schedule someone to come over to obtain the sample was really ideal.
The process was easy and informative.
They tested my well water and advised me on further steps I could take to make my well water safer to drink. Excellent follow up.
Technical analysis.
Neighborly initiative.
Your sample kit is mailed directly to you. Fill the bottle, mail it back, and receive results by email.
The screening establishes a baseline across important household water-quality markers, including Lead, Nitrate, and Fluoride.
Eligibility depends on your location and current program availability.
Some additional information
For qualifying households in select areas, the laboratory screening fee is waived in part 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.
Once your sample reaches our lab, screening is completed within 3–5 business days. You'll receive an informational report comparing each marker against published health-based reference guidelines, including EWG guidelines, EPA MCLs, where applicable, California Public Health Goals.
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.
Every screening includes the option to review your results with a Weluma Labs tech. They'll walk you through what each marker means and how your levels compare to Health Guideline ranges.
