Monitoring of drinking water distribution systems should undertake to capture the worst case water quality scenarios in order to provide the maximum protection for public health. Total coliform monitoring is expensive and time consuming relative to other chemical or physical measures of system integrity that may be monitored in real time. This paper proposes a methodology for mining these additional water quality parameters to inform coliform monitoring. Three machine learning algorithms are selected for application to a case study distribution system: i) gradient tree boosting, ii) decision trees, and in) distance-weighted nearest neighbor algorithm. In addition, the effect of expanding training data to include unlabeled data records will be explored. The performance of these data mining techniques should provide insight into the use of surrogate water quality parameters to indicate high coliform levels. This paper was presented at the 8th Annual Water Distribution Systems Analysis Symposium which was held with the generous support of Awwa Research Foundation (AwwaRF). |
