Buying water filtration is confusing and full of over-selling. Tapscore provides real, independent information and EXCELLENT customer service in interpreting results and understanding what type of filtration you need without any incentive to sell you a filter. You get live help from a knowledgeable real person in helping navigate - they saved me hundreds of dollars in not over buying or overcomplicating our water filtration needs for an a whole house approach.

I was looking for a detailed analysis of my water, and the test they offered checked all of my boxes. The process was very easy. They mail everything to you with a return shipping label. Instructions are clear. And turn around time was reasonable - quick enough for my needs in any case. The customer service is also very good. I reached out with a question and received a quick and detailed answer. Highly recommend.

I ordered several tests from Tap Score / SimpleLab, and I was thoroughly impressed. The kits are easy to use, shipping was fast, and the results were comprehensive. The best part of the experience is the customer service, though. I got in touch with the folks at SimpleLab through the online chat feature a few times with tons of questions, and they were always very responsive, friendly, knowledgable, and willing to help. Robin and Kelly are awesome!

In September we used Simple Lab to test our well water to see if it contained chemicals related to Parkinson's disease The results of the test were incredibly comprehensive and the explanation of the hazards for each contaminant were detailed, specific and useful. They discovered a contaminant that needed to be treated for our health aside from my original concerns and informed us about how to do so. The process of testing was easily done with helpful instructions and my follow up questions were answered swiftly and specifically. I highly recommend them.

Easy collection and return with clear results. My daughter did a urine test which showed high levels of Tungsten and Uranium so I am trying to find the source. Our Uranium level at the main kitchen faucet seems to be in "legal" range so more research to be done, but this is super helpful.

Drinking Water Testing is literally the most important easy test you can perform. We cannot test the quality and safety of our food in the same way we can test the water we drink everyday to stay alive. We are our 70's and have lived on farms and drunk primarily well water we thought was good tasting for over 50 years. Our current farm is in SoCal and the water districts in the LA basin 2 hours away have been quietly cloud seeding the last two years to increase rain due to drought conditions in many areas, but that activity has caused rainfall to double for us at higher elevations which has caused ponding on adjacent properties and our well water to become polluted with sediment and Coliform and Ecoli bacteria. As soon as we saw the sediment, we tested our well water with our usual testing lab and even had our well pump guy test it as well and were not satisfied that the results were complete and comprehensive. While trying to solve the well water problem, we were forced to go on bottled water for months and as we checked out every aspect of our well, one scientist referred us to Tap Source water testing operating as Simple Lab as the best testing lab in the country. We tested our well water with Simple Lab and they tested for and found pollutants that we have never tested for before. This forced us to tap into the local water district main line located in the area. Then, we separated the barn and livestock well water line from our home service line and installed a whole house filter system and tested that "city water" both unfiltered and filtered to make sure our whole house filter was working as advertised. Those two Simple Lab tests confirmed that the WHF was working well for filtering out the water treatment chemicals but not some of the more toxic organic chemicals in all groundwater. Simple Lab (particularly Kelly in customer care) helped us identify and work out resolutions for everything that the WHF was not filtering out, in two detailed email responses which were received by us within 24 hours of our reaching out to Kelly. Great company and service. I will never go back to the "hit and miss" labs we have used in the past. Blessings, John
