Test annually for bacteria
Aqua's approved guidance recommends an annual bacteria test and additional testing after flooding, well work, or an unexplained water-quality change.
Choose other tests from property risk
Location, geology, nearby land use, plumbing, lender requirements, and household concerns may support testing for additional analytes.
Use the correct collection method
Laboratory bottles, faucet preparation, handling, temperature, and holding time all matter. Follow the instructions for the exact test.
