ASTM-D5916 › Standard Test Method for Detection and Enumeration of Clostridium perfringens from Water and Extracted Sediments by Membrane Filtration (MF)
Show Complete Document History
The following bibliographic material is provided to assist you with your purchasing decision:
1.1 This test method can enumerate Clostridium perfringens spores and vegetative cells from marine water, sediment, wastewater, ambient water, and drinking water. Since C. perfringens spores are present in large numbers in human and animal wastes and are resistant to wastewater treatment practices, extremes in temperature, and environmental stress, they are an indicator of present fecal contamination as well as a conservative tracer of past fecal contamination. It is the user's responsibility to ensure the validity of this test method for waters of untested matrices.
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
