Excellent customer Service. We had a quick notice requirement and they exceeded our expectations. They worked with us the whole way and they met our needs before our drop dead date. Highly recommended.

Amazing experience, Kelly was so great and helpful. Can’t believe we were able to get the results so quickly. I would recommend them to anyone!!!

The process was easy and very efficient. The website is user friendly and I was able to share my report with people. The customer service(Kelly, specifically) was very helpful with my water retrieval questions and after figuring out the next step with my results.I appreciated the different ratings on my results(federal guidelines, EPA, etc). I have installed and whole house water filter and will repeat another test with Tapscore in a few weeks.

Tap Score team in particular was so helpful. we tested our well for the first time in a decade and found some uranium and iron and bacteria. Kelly helped us pick out a great filtration provider to help solve the problem. Ill be back!

Tap Score was consistently finding arsenic in my water (6 times over 18 months) but when I ordered a specification test it came negative. After several emails i was offered to redo the test if I pay for shipping. I ordered the same test from a different company and it came positive with a break to arsenate and arsenite. I understand errors are inevitable but not admitting them and not correcting is unacceptable.

Mr. Bokarius—Thank you for initially trusting us to help try and solve this problem. I am truly sorry things turned south. For anyone in California or the US Southwest where arsenic issues are common in water supplies, it’s crucial to know that Arsenic Speciation testing is a really sensitive endeavor (and we will be the first to warn anyone of this) because arsenic levels are particularly vulnerable to environmental redox conditions, rainfall and other geochemistry. You can not assume that your total arsenic or arsenic species will remain consistent. Whats most important is that if you do have arsenic in your water supply, at any regular frequency of testing, you should consider treatment and/or filtration because enough high spikes of arsenic in drinking water can make you sick overtime. If you have a private well, Test for arsenic. If it comes and goes in concentration spikes, don’t be alarmed—thats normal. In vane perhaps we hoped offering you a free retest on your latest Non Detect result would help you appreciate our care for this matter. Even with a 1-star review we remain here to help, if you have further questions we are a call or text away. Good luck sir!

Five stars to your company and Kelly! We have well water and had concerns about black gunk in our toilet tanks and orange ring in toilet bowl water. We did not know which way to proceed whether chlorine shock for iron bacteria, water softener, whole house filtration system, etc. Your lab test with instructions helped us make an informed decision as well as saving us money by identifying which system would suit our circumstances based on the water test results. After reviewing our results Kelly patiently and systematically answered all of my questions in detail. Now I can proceed with improving the quality of our water as well as prolonging the life of plumbing and appliances. The only addition I would make is to add to cardstock instructions (for iron bacteria testing ) reminding the user to put a piece of white paper behind sample before taking photo. This was in the online instructions, but not on the card stock instruction. Our photos turned out ok but definitely easier to evaluate with the white backdrop.

I had a very positive experience dealing with SimpleLab. The process was easy and the test results were thorough. When I asked questions online, everyone was patient and kind and very knowledgeable about what they do. I highly recommend SimpleLab.
