Abstract

The present work aimed to classify the irrigation water quality of surface water (Pond) and groundwater (shallow), Collected from different sources and different seasons in Canning Block, 24 South Parganas, West Bengal. Thirty water samples were collected in Pre-monsoon and post- monsoon for analysis of physico - chemical parameters like pH, Electrical Conductivity (EC), Chloride (Cl−), Carbonate (CO3−-). Bicarbonate (HCO3−-), Sulphate (SO4−), Calcium (Ca++), magnesium (Mg++), Sodium (Na++), Potassium (K+), Sodium adsorption ratio (SAR), Residual sodium carbonate (RSC). Analysed water samples of shallow tube well were found in pre- monsoon rated as 73.33% (C3-S1) under high salinity and 23.66% (C4-S1) under very high salinity water, but after post- monsoon were found of shallow tube well were 46.66% (C2-S1) water samples converted in under medium range and 53.33% (C3-S1) water under high range found. In respect of Pond water samples were found in pre monsoon 93.33% (C3-S1) samples under high salinity water and 6.66% (C2-S1) under medium range. After post monsoon of pond samples found 73.33% (C2-S1) in medium range and 26.66% (C3-S1) in high range.

Water samples of shallow tube well were found in pre- monsoon rated as 73.33% (C3-S1) under high salinity and 23.66% (C4-S1) under very high salinity water.

After the monsoon shallow tube well water converted 46.66% (C2-S1) in medium range and 53.33% in high salinity range.

Pond water samples in pre-monsoon were found 93.33% (C3-S1) in high salinity range and 6.66% (C2-S1) in Medium range.

After monsoon Pond water samples were found 73.33% (C2-S1) in Medium range and 26.66%(C3-S1) in high saline range.

Pond water is more suitable for irrigation in pre and post monsoon for these areas.
