The Ultra test is a great option for testing well water as it covers many minerals/metals and other inorganic compounds that can be naturally occurring due to the various geologic formations in the area. In addition, this test looks for volatile organic chemical which can be found due to leaking underground storage tanks and possible nearby industry. Testing also includes radiological contaminants which are present in all natural water to help determine if they are present at a safe level. Finally, this package includes testing for PFAS contaminants that have been found in well water that is located nearby manufacturing plants, airports and military bases. This testing package covers all the major cations, anions and physical characteristics, volatile organic chemicals, radiologicals and PFAS contaminants that are important in determining what water treatment option will work the best given the water quality including:• (29) metals and minerals• (7) other inorganic compounds • (9) physical characteristics• (53) volatile organic chemicals• Radiological contaminants gross alpha and beta • (18) PFAS contaminants including PFOA, PFOS and GenX(1) 1000 mL bottle(1) Sorbent Material
