Easy to follow directions to perform the testing, easy to understand results. Thorough explanations and suggestions

The process for testing is very straightforward and the web site is very easy to use. In addition, I encountered a problem bringing up my status for a test, and I contacted them via chat. The response was immediate, and after some discussion and some screenshots, it was addressed the same day. It was real humans, no chatbots or having to jump through hoops to get to an answer.

The guidance and response time is off the charts. I felt informed, helped, and thoroughly satisfied the whole way through, from getting the test I ordered, getting my results, and even getting help online in the chat to better understand my results.

I've tested our tap water multiple times while trying to figure out how to remove lead from it. Tap Score was a really convenient and accurate way to do that. We realized the faucet was the source of the lead and got great quality drinking water after replacing it.

I live in Wilmington, NC and have been dealing with contaminated water from the Cape Fear River (thank you Chemours) since we moved here 5 years ago. Recently, our water provider completed an R-O plant installation connected to 5 virgin wells to provide clean drinking water free of contaminates. I ordered 2 kits - 1,4 Dioxane and GenX/Pfas to ensure that the new water source had not been contaminated by the forever chemicals that Chemours had been releasing into the river for who knows how long. The 1st test (1,4 Dioxane) results came back within the provided turn time. However, the 2nd test (Pfas/GenX) took significantly longer than projected when I signed up for the test. I spoke with customer service who were very accommodating and helpful, but rather ineffective in getting the results from the lab which was in Wilmington, NC about 20 mins from my home. I was so annoyed with the excuses and delay after delay that I finally got the owner of the Simply Safe company involved who moved the testing up to an expedited level. I was told the reason for the lengthy delay was the significant backlog countrywide for this forever chemical test. No one could tell me why they don't advise customers of the long delay or why an updated completion date isn't provided. Communication from the lab to customer service to the end user is HORRIBLE! The estimated completion date provided on the website should reflect reality, not a standard calculation. Other than this issue, I am satisfied with the results.

I heard about Tap Score from a NY Times Wirecutter review. I used the test to measure the PFAS levels in my drinking water after running it through my filers. My water provided indicated that we have PFAS in our water and the test confirmed there were no traces after filtration. I was pleased with the service: good instructions, quick delivery, online results, etc. I would have like to have more things tested but the costs were a bit steep for me. Maybe a bundled approach with a discount off the individual testing price. All in all a good experience that increase my confidence in my drinking water.

Tap Score helped us completely change our water for the better! The kits are incredibly easy to use, delivery and testing time is fast, and the results are clear and easy to digest. The suggestions for solutions gave us a lot to consider and we referred to our results many times as we selected a whole house water filter. We felt empowered and confident to make the right selection based on the test findings because of it's thoroughness and clarity. Tap Score's service is unique because they are independent--we were not pressured by a plumber or other professional to use their specific system so we were able to take our time to select what was best for our water, lifestyle, and house. We re-tested after we installed our filter and were thrilled with our much improved results! We've recommended Tap Score to family and friends and will continue to--we have heard great things from everyone who has also used this service!
