Abstract/ Executive Summary:

Application of agrochemicals materials, water of sewage, and contaminated water in drain has become a serious threaten condition to groundwater for Intensive agriculture. The main theme of the study was to evaluation the quality of groundwater and to spatial difference of their mapping in terms of appropriateness for the purpose of irrigation and drinking. Ordinary kriging technique was applied for preparation of thematic circular maps of several hydrochemical and IWQI parameters such as electrical conductivity, sodium adsorption ratio, and magnesium/calcium ratio, total dissolved solids, chloride, and hardness, KI, PI, SSP. Irrigation water quality index model was considered best fitted where determine all quality parameters together in a process. The contamination level was maximum at the north part of the investigation area. Excellent quality of groundwater may be identified at the middle and south middle part areas of the groundwater quality is good. Here high salinity indicates the higher chloride concentration of the groundwater. High dissolved solids and total hardness made eastern part of the groundwater inappropriate for irrigation. There were also found lower sodium and magnesium hazard in the investigate area. The groundwater quality index was developed to investigate the combined influence of several quality parameters on irrigation purposes

Program Area: Crop-Soil-Water Management

Commodity: Water productivity

Objectives:

The Sagardari union, the main studied area, is required to use 50% of its water prerequisite from groundwater resources. The unlined drains which are opened and the removal of pollution in different locations in the recharge extents act as pollution source of groundwater.

Methodology:

1.1. Location Sagardari is a union in the Keshabpur Upazila of Jahore district, built on the bank of the Kopotakho River, which is famous for poet Michael Madhusudan Dutt’s parent house.

The weather of this areas is moderately subtropical with normal annual precipitation and evaporation is also moderate separately. For this research 40 deep well water sample were collected from different location.

2. Samples that were collected from the study areas were evaluated in the AAS-Jashore laboratory for the quantity of concentration of the superiority parameters using standard techniques. The superiority of groundwater for deep tube wells were compared to standard level from higher or lower. It showed the distributional areas of geochemical water sample by GIS. Consistently the restrictions of temperature, pH was designed in the selected area by applying a Thermometric and Electrometric system. The laboratory analysis of parameters was identified with the main ion’s absorption (Na+, K+, Ca+2, Mg+2, Cl-, As+3, temperature, pH, electrical conductivity, hardness, salinity, manganese determines the total samples of groundwater.

Achievement/Findings:

Environmental resources are groundwater and its superiority deprivation are an apprehension of important societal and environmental issue. The main aim of this investigate area was to map and estimate the groundwater quality. Spatial circulation of groundwater superiority strictures was carried out by GIS and geo statistical methods. The quality of groundwater hydro chemical substances was transformed different restricted areas from a normal circulation. Highly contaminated groundwater sectors were mainly found at the eastern corner of the investigated areas. Comparatively south and west part more good quality of groundwater then the other part. The hydro chemical investigation exposed that problem of sodality was very low to nil but additional absorptions of chloride and TDS, and the rate of water hardness, make the groundwater at some locations undesirable irrigation in eastern corner. The stimulating and most significant outcome of this investigation was IWQI which areas is more excellent for irrigation and lower or higher pollution by different groundwater chemical parameters. The groundwater quality index was considered very helpful to investigate the joint impact of several quality parameters on irrigation with their distributional plotting maps.
