COLIPHAGE

Coliphage are viral indicators that infect and replicate in coliform bacteria, primarily E. coli. The OWML analyzes water samples by use of two USEPA-approved coliphage methods—the two step enrichment procedure (presence or absence results) and the single-agar layer procedure (quantitative results).
