Interpreting Tap Score Grades

We know that laboratory water quality reports are almost always lacking in context and are painfully difficult to read, making it difficult to understand what threats exist in your pipes. Because the quality of the water you drink and cook with every day is so important to your health, we seek to make sense of this complexity with Tap Score. We've designed intuitive graphics and use plain English to explain everything you’d want to know about each contaminant in your water, with the integrity of an official EPA water quality assessment.

Not only does each contaminant present in your water appear prominently, but we calculate an overall Tap Score to make it easy to quickly compare the overall quality of water from different sources. The Tap Score can be interpreted as follows:


Very Bad
