Start with the reason for testing
What do you need to learn
about your water?
Keystone PHS, a division of Keystone Elements, helps you start with a clear testing request—not a guess about which equipment or test panel you need.
Testing before treatment
Understand the water you want to treat before selecting a softener or filtration system. Existing test results, your concerns, and details about current equipment help guide the conversation.
DEP-related requirements
Have you been asked to provide water testing? Tell us who requested it, the reason, and any deadline. Share written instructions so sampling and documentation requirements can be reviewed first.
Required or regulatory testing? Confirm the required test panel, sample handling, and laboratory qualifications before samples are collected. Keystone PHS is not a DEP agency. Pennsylvania DEP recommends using a state-certified laboratory for drinking water tests. Read Pennsylvania DEP’s water-testing guidance ↗
