Robin did a great job providing general guidance on a processing system for my water well. She did not push any particular supplier just how to clean up the water impurities and hardness.

Their customer service is top notch! Every email I wrote received a personal reply and they worked with the lab to get me our test results one day early. The results are easy to read and unbiased. So refreshing to get help from people who aren't trying to sell us something!

Edit: after hearing back from the owner and speaking to customer service I am revising my rating. Although I hope they possibly change the name of the updated test or add a clarifying paragraph to that page so others don't experience the same confusion, I am updating them to 5 stars as the test I did in November of '24 was thorough and easy to do and the results were clear and came a lot faster than those of their competition (whose test we did a few months prior.) The test we did with Tap Score in November 2024 was really thorough. We tested our well water using their "Advanced Well Water Test" post hurricane Helene and it was super helpful. It cost $295. I wanted to do the same test again for a different reason, to test our house water post filtration to see if the filters had any issues, and I went to their site and the exact same test (well, it seems they are testing for 114 analytes instead of the 108 in my test last year) and the price is $485!! Virtually identical test. One year later. That's insane price gouging. Shame on you Tap Score.
Response from Tap ScoreNov 6, 2025
Hi Ali ! Johnny here. Owner of Tap Score . I am so sorry for the confusion. It sounds like our product name changes are the root of this confusion . My apologies. You are in fact comparing two different test kits, thats why the price is so different. Let me explain 🙌😇☀️ We updated the old Advanced Well test to now include more contaminant analysis AND to include, by default, overnight shipping both ways, plus wet ice in a cooler. This improved the accuracy of the coliform and nitrate results in particular . It did unfortunately increase the cost, substantially. That being said—the former test kit that you originally bought is still available . It has a different name now though, and the GOOD news is you can order it at the same or lower cost as an existing customer. 🤗 So ultimately, yes the name of the test kit and nature of whats included did change substantially , and hence the confusion. I am really sorry. Please reach out to our support team at [email protected] and we will help you out. I have already alerted them that you might be coming , so dont hesitate to say you are The Ali that Johnny mentioned. Kindly Johnny

I had several questions regarding water testing. I spoke with Kelly from Tap Score who answered my questions. She was extremely friendly and knowledgeable. I highly recommend this company.

I had some questions about the water quality report I received so I reached out via the help line. Robin was extremely helpful and informative, walking me through the test report and recommending additional testing, and then providing advice on treatment specialists. Highly recommend this company, excellent customer service.

I can't say enough for the professionalism from start to finish. The testing was simple and the instructions were perfect. Receiving my results were right on time with great detail. After reviewing my report I started a chat to ask some questions expecting a bot but instead I got Robin. All I can say is she was excellent answering my questions while adding a comfort level to the quality of my water. I did my research before using Simple Lab so I expected quality and I received it 10 fold over. This company is what all companies should strive for. I also learned my report will be on their website forever which gives reassurance if I ever need the report. All I can say is you will be happy with the product and the service.

Having you private well water tested is a good idea. It might seem frightening. I wasn't sure I really wanting to know. How would any issues be resolved. The crew at simplelab are skilled professionals, knowledgeable, and efficient. They provided understandable answers to my questions. They respond quickly, offering step by step support through the collection, mailing and importantly helping me understand the results. Very personal service by experts at their job, looking out for my health and well being of my family and friends. I have an element in my water to be removed. It will be easy, using modern, available technology. So glad I had my water tested.

Excellent service. The results and explanation of the results were very comprehensive and the recommendations honest and clear. I would highly recommend Tap Score to anyone interested in their water quality and would totally do your own testing prior to investing in a water filtration system so that you have your own data to compare to the salesperson's.
