3.1. Location
The study area (Wellpoint) is situated beside the Bay of Bengal. The
longitude and lattitude of the studied area are 92°03’ to 92°12’ and
21°08’ to 21°21’, respectively. It is situated on the last corner of
Ukhia Upazila, Cox’s Bazar (Fig. 1). The humidity is very high in this
area. Every year (July-September) different disasters attacked this
area. Tidal saline water from the sea is another problem in the studied
area. The temperature of seasonal variation in winter to summer is
considered around 12-42 degrees. The rainy season occurs stay in high
time because of the seasonal monsoon every year. Sometimes heavy
rainfall is formed seasonal characterization bay of Bengal. In summer,
the temperatures are also high (over 42 degrees). The borehole areas was
selected to reach the maximum number of water supply without any risk of
flooded away during the rainy season and the land was not stored any
stagnant water. In the north-western zone, this wellpoint area is one of
the most readily available fo the water supply in these areas for
agriculture. As this area is the coastal part of Bangladesh therefore,
safe groundwater evaluation is the urgent need of this area.
