Assessment Of Water Quality Of East Hammar Marsh Using WQI, Basra-Iraq

Abstract

The Canadian Water Quality Index (CCME WQI) was applied to assess the water quality of three (3) sampling stations in East Hammar marsh during (Nov.2012) to (Oct.2013). The historical studies before/after restoration were used during the evaluation process.Water temperature, Salinity, Transparency, pH, Dissolved oxygen, Reactive Nitrate and Phosphate were selected to calculate the index.The results revealed that the WQI ranged between (28.2 – 49.6) and (40.7 – 62.7) depending on the historical studies before/after drainage respectively, classified as (poor) to (marginal). The study revealed that the water quality of the east Hammar marsh was better than its quality after three years of restoration.
