E.COLI/COLIFORM (25 TESTS)

This test is designed to detect total coliforms and E. coli, providing a straightforward assessment of the microbial quality and sanitary condition of a water sample. Total coliform counts serve as a basic indicator of potential contamination in a water supply, while E. coli detection specifically identifies fecal contamination, making the test suitable for both general hygiene monitoring and more targeted safety assessments. The procedure requires incubation at the correct temperature to ensure reliable bacterial growth, and methods involving E. coli use a UV lamp to visualize fluorescence produced by β‑glucuronidase‑positive colonies. The methodology aligns with EPA‑approved microbiological test procedures referenced under 40 CFR Part 136.3, ensuring consistency with established regulatory standards. (UV lamp supplied separately)
