You can also check your utility’s consumer confidence report (CCR). It will show the test results of water leaving the water plant. It won’t reflect lead levels at your home, which are impacted by your own piping. (It may include lead sampling at random locations around the distribution system.)

Collecting your own sample is perfectly fine. There are special instructions if you are specifically testing for lead that your utility should be able to provide to you. Contamination is really only a concern when testing for PFAS, but that test alone may cost more than your treatment system. Look at the PFAS data from your utility if you are concerned and realize you may be getting more exposure to PFAS from other sources than your water (Teflon cookware, food packaging, cosmetics, etc.).

In general, someone in the business of selling home treatment systems is has an incentive to tell you your water is poison and you absolutely need their system.
