"It was easy and gave us a lot of good details. We learned that we do not have arsenic in our well water. We also learned our water is super hard and the report actually said "do not water your plants with this water, it will kill them" I just thought I sucked at growing plants, it's nice to know its not me, it's the hard water."

"This test is worth it. It is the same price or cheaper than any lab I've seen, but you just mail it in. The results were were extremely detailed and the online interface is very user-friendly and easy to understand."

Simple interface and useful information make this a good value. I live in a 1956 airspace condo with good pipes but bad maintenance, so for everyone’s peace of mind I went ahead and got this done (and also previously ran basic asbestos tests on the plasterboard and ceiling popcorn. We’re all good here!

The testing done is superior to what we had done by a local company. This makes it an excellent value for those of us that are on our own wells. If you want a water test that is outstanding check these folks out.
