Irrigation water quality assessment of Betagi Upazila under Barguna district in Bangladesh

Received: 13 September 2019 Revised received: 10 October 2019 Accepted: 16 November 2019 Irrigation water quality is important for the successful crop production. The present study aimed to assess the quality of both ground and surface water for use of irrigation purposes at Betagi Upazila under Barguna district in Bangladesh. Forty two water samples were collected from different locations and their important chemical properties including pH, EC, the concentration of PO4 , SO4 , K, and Na were analyzed. Results revealed that the pH of the ground and surface water were ranged from 7.23 to 8. 49 and 6.98 to 7.96, respectively. Electrical conductivity (EC) of the water samples were 590 to 1950 μ Scm and 110 to 380 μ Scm respectively. The PO4 3concentration in groundwater was 0.10 to 0.74 mgL and surface water was 0.05 to 0.20 mgL. The SO4 2concentration of groundwater ranged from 1.29 to 3.10 mgL and surfacewater was 2.11 to 7.28 mgL. The K ion concentration was 4.55 to 11.38 mgL in groundwater and 6.12 to 22.44 mgL in surface water. The PO4 3and SO4 2-
