Consistent production of chlorine-stressed bacteria from non-chlorinated secondary sewage effluents for use in the U.S. Environmental Protection Agency Alternate Test Procedure protocol
The U.S. Environmental Protection Agency Alternative Test Procedure protocol outlines a method to produce chlorine-stressed bacteria for water quality testing. Achieving consistent results is challenging due effluent variability. We describe a starting point for generating chlorine-stressed samples from secondary effluent to evaluate detection technologies to demonstrate comparability to EPA reference methods.
