The National Field Investigations Center-Denver (NFIC-D) has been engaged in water quality and waste source evaluation studies since its inception. Due to the magnitude of the surveys, NFIC-D often has relied upon automatic samplers, particularly the SERCO, to collect samples of the wastewater streams. These samplers are used to collect water samples over specified periods for subsequent compositing; individual grab samples are collected manually. With the advent of compliance monitoring, the use of automatic samplers is expected to increase. Data provided by the manufacturer show that the automatic and manual sampling methods are equivalent. To confirm that the sampling methods are equivalent, NFIC-D conducted studies at a local wastewater treatment plant (WWTP) and statistically evaluated the results. This paper presents the results of these studies.
