If you suspect your water is making you sick the first thing to test for is Presence/Absence of Coliform Bacteria and E. coli. This is a simple $20 test with results available in one day. You can get more information at our Coeur d’Alene lab by calling 208-665-5666.
Another common drinking water test is Nitrate and Nitrite. This is especially important if infants are in the home.
