Statistical Associations between Coliform occurrences in Water Samples and Fluctuations inChemical, Physical and Biological Factors

Price: £15  

This report identifies statistical associations both at the sample and zonal level, between coliform occurrences and other routine determinands in statutory monitoring data provided by water suppliers. It also develops and validates simple alogirthms for predicting increased probability of coliform failures. Plate count numbers were found to be a good predictor of local deterioration in water quality (with respect to coliforms) within a zone but not a very useful predictor of general differences between zones. The models developed appeared to predict quite well from one period to another, but not very well from one company to another.
