Salinity Assesment By Using Gis Model To Explore Safe Water Options In South Coast Of Bangladesh

Salinity intrusion is a growing problem in coastal areas around the world, particularly in low lying developing countries. Especially in the dry season, this problem becomes even more complex when there is insufficient rainfall and incapable of lowering the concentration of salinity on surface water and leaching out salt from the soil. Sea temperature, Typhoon and storm related to the risks of climate change, as are the problem. Sea level rise is not the difference between each geographic location. The current climate seems to be based more influential. In addition, an increase in the sea level and geographical location as well as population density, lifestyle options, poor infrastructure, inadequate policies and skilled technology such as socio-economic factors. Study of qualitative data collection and analysis for both qualitative methods and applied. Collect information using both primary and secondary sources. Salinity levels, focus group discussion (FGD), key informant interview (KII), House-based interview, interview and personal observations can help to measure the EC meter the water by 2015 and 2016 through the sample spot test of basic information was collected. Based on the study objectives and data need assessment the relevant data and information were collected. The major data has been collected from DPHE, BWDB, BARC, NGO’s and field survey. By developing salinity hazard maps using GIS based model to identify areas where landscape salinity might be an issue and apply the developed model to assess the present scenario of salinity and drinking water scarcity due to climate change effect. Groundwater samples for drinking water quality purposes. Because there is no major industry located within the study area, so did not perform water quality analysis for industrial uses. Analyzed groundwater quality for drinking based primarily on World Health Organization (WHO) and Bangladesh Drinking Water Standards (BDWS). The water supply systems have been proposed, based on field visit and assessment of site conditions, available primary and secondary data/information, and consultation with potential users. Poorly managed water supply system can pose high health risks in a local public. Poor hygiene in collecting, storing water in and abstracting water from rainwater tanks or at the point of use can also represent a health concern. However, risks from these hazards can be minimized by good design and practice. For Operation & Maintenance, particularly for Pond Sand Filters and Rainwater System, specific arrangement will have to be made to keep these functional and ensure safe drinking water. Ensuring access to safe drinking water is one of the most important issues for human health and sustainable socio-economic development in these areas. And sustainable supply as well as access to safe drinking water cannot be achieved without involving the local community in the planning and development processes.
