Indicator available Proportion of bodies of water with good ambient water quality (Water quality index)
Indicator description Proportion of bodies of water with good ambient water quality (Water quality index)
Geographical coverage National
Unit of measurement Percentage (%)
Definitions Percentage of water bodies in each status class has been calculated based on the total number of water bodies assessed in each year
Calculations Water quality will be measured by the Water Resource Commission (WRC), by taking samples from monitoring sites established across the country, across different basins. The 10 parameters (DO, BOD, NH4-N, FC, pH, NO3-N, PO4-P, TSS, EC and Temperature) will be monitored twice a year.
