If your total coliform test is positive for total coliform and E. coli, the water should not be used for drinking water unless boiled well. Corrective actions to the well and/or chlorination of the system should be undertaken. Treatment systems such as ultraviolet (UV) or chlorination can also be considered. Quantitative E. coli results for irrigation and swimming should be compared to standards.
