Even small improvements to drinking water quality bestow meaningful health benefits to your mind and body over time. Making easy, smart changes to every day water quality consists of testing for and removing harmful chronic contaminants, many of which have no color, smell, or taste.

As a growing team of civic-minded engineers, lab scientists and health experts, we share a vision to improve the way you test, treat, and monitor your drinking water and local environmental health.

Testing in a Certified LaboratoryCutting Edge Analysis and Health Reporting

Professional Laboratory Testing

SimpleLab is committed to offering families, individuals, and small business customers the most useful, efficient and affordable water testing services available in the USA.

Traditional environmental testing laboratories make most of their money from large, recurring clients like the government. When your top customers buy water tests in the thousands, the individual buyer doesn't get the attention they deserve. We are here to provide innovation and customer service to the the world of water testing, where it has long been missing.

SimpleLab has partnerships with some of the top environmental testing laboratories in the Nation, allowing us to improve the testing and reporting experience for all customers. We enable the lab technicians to focus on what they do best, testing water. Meanwhile, we deliver on the promise of great customer service, expert treatment advice and timely support. Tap Score testing is performed with EPA, ASTM, and other common industry testing methods. We also offer state regulatory compliant testing, just ask!

With Research Support From

Health Analysis

In partnership with The University of California in Berkeley and the Boston University School of Public Health, SimpleLab developed cutting edge water health analysis that is applied to every Tap Score Report.

Small amounts of harmful contaminants, many of which do not smell, look, or taste like anything at all, cause serious physical and mental health effects as they build up in your body. The key to protecting yourself and your family is having reliable and convenient access to high quality testing, health analysis and personalized treatment matching.

Personalized Treatment Matching

treatment matching for nsf and wqa certified products

We do not sell our own treatment technology.

We do not partner with any water treatment companies.

When you become a Tap Score customer and discover something you don't want in your water, we provide you with unbiased treatment recommendations based on the specific contaminants found in your sample, your home preferences, budget and our ongoing research into customer satisfaction with different treatment solutions.

Beware "free water tests" sold by companies that also sell treatment products. We've tested these ourselves and they are, as you might expect, merely a vehicle for selling you expensive treatment you might not need.

The treatment products we recommend come from several high quality brands that are certified by NSF International and the Water Quality Association

Our Story

We started SimpleLab to help people drink safe water. Our first mission was to help disadvantaged communities remove arsenic from their water supplies. In the process, we invented new techniques for using electrochemical bonding to remove this dangerous contaminant before it reached people's taps.

While out on the field, discussing water issues with real people who were affected, we discovered something even more important than any new treatment technology: that many people did not test their water because the process was confusing and uninformative.

So we set out to find a better way.

Tap Score is the result of re-imagining how people relate to their drinking water and its impacts on our health.

One in three customers will find something in their water that they'd rather not be drinking, and about half of those will find something that unequivocally imperils their health. This includes customers in major metro areas and places where many assume the water is always safe.

SimpleLab and Tap Score provide the best way for you to protect your health while authorities continue to roll back clean water laws. When you test your water with Tap Score, you are also supporting our effort to create a better system for testing and monitoring water quality around the nation, so we can all know what's really coming out of our taps.
