The US Environmental Protection Agency (EPA) and NSF* have determined which contaminants are the most detrimental to our health and have set limits for these contaminants. The list is not comprehensive list - but the best recommendation and frame of reference. We test for many more contaminants. You can reference those on our website for the complete list of contaminants we test for. Also, for the key microbial and chemical contaminants we meet or exceed those standards.
*The NSF helps set public health standards guidelines in the USA to protect the world’s food, water, consumer products and the environment. The EPA ensures safe drinking water for the public in the USA, by setting standards for more than 160,000 public water systems nationwide.
