REC-STAT is a Microsoft Excel based spreadsheet which allows you to perform a CLR7 (DEFRA guidance) statistical test on regular gridded and normally distributed data, such as soil contaminant concentrations. The spreadsheet has been developed by REC to allow for the derivation of max value tests and also determine whether the mean of the population (at the
95 percentile confidence level) is greater than the Soil Guideline Value or risk based screening level.

Further information on the operation of the spreadsheet will be available to download after registration.
