Convenient, responsive service. If they perform other tests, I would recommend they offer this prior to taking the sample and after receipt of the sample.

I sent in two PFAS tests, one unfiltered tap water and one filtered tap water. I got fast, timely results for a fraction of the cost of a local lab.
