Blind Audit

The Chesapeake Bay Blind Audit Program was initiated in 1998 to help agencies and laboratories identify and correct analytical and/or field sampling problems before monitoring data are applied to a long term data base and subsequently used to make management decisions. Twice a year, in summer and winter, low-level nutrient samples are prepared by Nutrient Analytical Services Laboratory. The samples are then sent to participating laboratories with a set of instructions for analyzing. After results are submitted and reviewed a final report and laboratory comparison is prepared. Each laboratory is then sent a copy of the final blind audit report. Discrepencies are noted and laboratories check their results if they do not have a reported value within the expected range. The Blind Audit Program is funded by the Chesapeake Bay Program and Maryland Department of Natural Resources.
