Raw data is nice but explaining if there is something to worry about would be priceless.

Hi Colin - There is a link on the second page of your report that will take you to EPA.Gov/PFAS, where you can learn more. Or give us a call at 312-639-5009. We’re always happy to help you read your report. Email works [email protected]. Thanks!

I wanted to have my water tested not just for plastic but for other containments. Sadly this didn't offer that.

Long processing time due to lab move, which was poorly communicated. The first notice I got about delayed processing time referenced a prior notice that I never received. When I reached out to support for clarification the person I communicated with (VP of Marketing, of all people) was very curt and borderline rude. The product seems good and easy to use but communications and service really sucks. Lastly, I remember the instructions in the kit being a little hard to follow but I found a video online that was way better.

I send the samples in November. I know you're making some changes to your facility but I took a long time to get this sample back

Getting this EPA approved would be helpful. I’ve tried other companies and results vary.

Hi - We just reviewed the data input from the order and the state was abbreviated incorrectly when entered in our Excel spreadsheet. We will correct the state in the report, changing it from from Massachusetts to Maine. We will resend the report now. Our sincere apologies for the error.
