Quick, easy process to order, collect sample water, and return ship. Instructions were clear. No issues at all. Thank you for offering this service at a reasonable price and for streamlining the process. Highly recommend!

I had to search your literature to find out what the things were that you found in my water. I would have appreciated it if you could have directed me to information about the things you found in my water.

I made some mistakes in submitting my sample. The lady that called to clarify was extremely kind and patient with me.

Customer service was informative and willing to answer all of my questions, and they didn’t try to sell me a service I did not need. I paid for the PFAS test and received it in 2 days. I sampled my water and sent it back immediately. Within 5 days my results were in my email. I learned about chemicals in my water that I was unaware of. I knew abt PFNA and PFOA, but PFHxA was unexpected and never reported on by my municipality as being a contaminant in our water. The PFHxA level was more than double what the EPA considers as safe.

Great value for a reasonable cost, kept us updated when they received our results, and got us our results promptly.
