High-precision testing to detect total coliform and E. coli bacteria in drinking water—two indicators of potentially harmful contamination that are especially critical for private wells and springs where nearby sources can infiltrate groundwater supplies. Presence/absence testing remains the industry standard because any detection of coliform or E. coli signals a problem that requires immediate attention, regardless of colony count. This test gives you the clear yes/no answer needed to determine if treatment or disinfection is necessary. The package includes all required materials for proper sample collection and certified laboratory testing. Results provide detailed presence/absence analysis for both total coliform and E. coli bacteria.(2) 60 mL bottles(1) Sampling syringe(1) 0.45μm Nylon membrane filter(1) Adaptor(1) Cartridge with filter media(1) Sorbent Material
