Aquatic Biology Associates, Inc. has quantified the results of macroinvertebrate samples in the State of Idaho for two large USGS water quality projects: our Statewide Water Quality Network and the Boise River Water Quality and Biological Integrity Sampling Network. Since 1994 the USGS Idaho Water Science Center has received complete and accurate macroinvertebrate data that meet all of our data quality objectives for very reasonable prices. Bob Wisseman has given us personal and professional assistance in identifying objectives for the use of macroinvertebrate data in our water quality studies as well as helped our office in reporting results. Bob is always available to answer any questions posed to him about our data. His lab has also provided quality assurance data to help identify sampling needs to reduce analytical error.
