Optimal Choice of Defluoridation of Okpoko Water Scheme using Decision Tree Analysis

Abstract

This paper addresses issue of excessive level of fluoride in drinking water supplies as a major problem in Okpoko industrial area of Onitsha. Thus, a rationale of low cost defluoridation methods is proposed in this area of no alternative water source except boreholes. Decision theory analysis is used to determine the lowest maintenance cost as optimal solution.
