Abstract

This study assesses water quality in the Pra Basin after the implementation of Integrated Water Resources Management (IWRM) using the water quality index (WQI). The study reports on changes in WQI before and after the first cycle of the implementation of IWRM. The Wilcoxon signed-rank test was used to statistically establish the significance of any difference during the implementation of IWRM. Eight (8) water sampling points from upstream to the downstream of the Basin were selected for sampling. Eight (8) physico–chemical and microbial parameters were used for the water quality measurement .Dunkwa-On-Offin (D F) recorded the lowest WQI whilst Adiambra (A M) recorded the highest WQI. The deterioration in D F has to do with the numerous and advance system of illegal mining occurring in D F and the tributaries which feeds it. The study revealed that water quality has deteriorated as a result of the high levels of suspended solids in the rivers. For WQI, the deterioration was significantly high during the IWRM implementation (Mdn = 40.25) than before the implementation (Mdn= 72.19) T = 0.00, p = 0.012, r = 0.66.The presented results, create doubt about the practicality of the action plan and the compliance of the basin officers to the action plan.
