ETR Labs

ETR Labs is a water-testing laboratory that helps households and organizations understand the quality of their drinking water. Established in 1995, the company performs testing in its in-house lab, with panels covering hundreds of contaminants and potential hazards, including lead and other heavy metals, PFAS, bacteria, radon, minerals, pesticides, and industrial chemicals. Customers can choose kits for city or well water, from basic testing to broader premium and ultimate panels, as well as tests for individual contaminants.

The process is designed to be straightforward: collect a sample using the supplied materials, send it to the lab with prepaid return shipping, and receive an emailed report detailing the results. ETR Labs says many tests have a two-to-four-business-day turnaround, while some comprehensive panels take longer. Each test includes a free expert consultation to help customers understand their findings and consider next steps.

The company also offers water-testing resources, including sample-collection guidance, maintenance information, FAQs, and a contaminant glossary. It serves customers nationwide and works with professional organizations across several industries
