Scope
Main technical content: This document specifies the method of using a high-efficiency microbial growth analyzer to determine the thermotolerant Escherichia coli in water, including sample collection, storage, testing procedures, and testing steps. This document is applicable to the rapid quantitative determination of thermotolerant Escherichia coli in surface water, groundwater, domestic sewage, industrial and agricultural wastewater, and estuarine water (with a salinity of ≤2%). The linear detection range is 100 to 108 cells/mL.
