Environmental Protection Final Draft Report ANNUAL CLASSIFICATION OF RIVER WATER QUALITY 1992: NUMBERS OF SAMPLES EXCEEDING THE QUALITY STANDARD June 1993 FWS/93/012 Author: R J Broome Freshwater Scientist NRA C.V.M. Davies National Rivers Authority Environmental Protection Manager South West R egion ANNUAL CLASSIFICATION OF RIVER WATER QUALITY 1992: NUMBERS OF SAMPLES EXCEEDING TOE QUALITY STANDARD - FWS/93/012 This report shows the number of samples taken and the frequency with which individual determinand values failed to comply with National Water Council river classification standards, at routinely monitored river sites during the 1992 classification period. Compliance was assessed at all sites against the quality criterion for each determinand relevant to the River Water Quality Objective (RQO) of that site. The criterion are shown in Table 1. A dashed line in the schedule indicates no samples failed to comply. This report should be read in conjunction with Water Quality Technical note FWS/93/005, entitled: River Water Quality 1991, Classification by Determinand? where for each site the classification for each individual determinand is given, together with relevant statistics. The results are grouped in catchments for easy reference, commencing with the most south easterly catchments in the region and progressing sequentially around the coast to the most north easterly catchment.
