This is the mail-in test kit that informs you of the quality of your home’s drinking water. Simply send a water sample using the included vial and prepaid, pre-addressed shipping box, to the EPA certified laboratory where scientists test for 15 contaminants including metals (lead, arsenic, copper), in-organic materials (chloride, nitrate/nitrite), and physical properties such as hardness and pH. By highlighting any potential problems with water quality, the test provides homeowners with the information they need to take action and make sure the water their family drinks is clean and safe. Test results can take one to two weeks and include an easy to understand key that notifies one of their water’s concentration of each contaminant. Includes additional vial and instructions for an at home E. coli and Coliform test. 7" H x 6" W x 1 3/4" D. (4 oz.)
