Bangladesh faces a major challenge in supplying safe potable water to the most of her 160 million people. The drinking water in Ba ngladesh is largely sourced from hand- pump tubewells, which draw drinking water from shallow aquifer, which has been badly polluted with Arsenic in recent years. Although various methods have been proposed to solve this problem, an acceptable and sustainabl e solution is yet to be achieved. As an alternative, rainwater can be harvested and used to secure the safe potable water for Ban...

Many different methods for calculation of the settlement of shallow foundations on coarse soil is used in engineering practice. In all these methods, the greatest impact on the calculated settlements have applied loads, adopted values of soil parameters and foundation width. It is common that in thes e calculations adopt soil bearing capacity that is significantly lower than actual, so the calculate d settlement of the soil is significantly larger than the actual, which results in a conservative foundation design....

The soils in the study area Zemianske Kostolany were polluted with fly ash material after dam failure of the coal-ash pond (1965). Fly ash represents possible source of potentially toxic elements, because meteoric water or groundwater may percolate through and interact with the ash materials in soils, producing leachates that contain elevated levels of trace elements, in our case, arsenic. The main objective of this study was to assess the potential of arsenic releas e into the environment. Amount of released arse...
