ASHTAMUDI LAKE & HIGH SALINE SAND
Contractors in the Kollam district have been rampantly using sand mined from the Ashtamudi lake for building works. Tests conducted by the material testing laboratory at the TKM College of Engineering found that sand mined from Ashtamudi lake is unfit for construction because of its high saline content. Widespread complaints that concrete portions and plastered walls of such buildings were flaking off. The test revealed that the chloride content of the sand stood at 2.268 percent, which is very high. The buildings consructed with such sand would have a life of only about ten years.
In the wake of the test result, Parishiti Samrakshna Ekopana Samithy called for total ban on sand mining activity had also posed a major threat to the ecology of the lake.It was also damaging the rich fish wealth of the lake there by affecting the livelihood of the inland fishermen. The sale of sand from Ashtamudi Lake was outright cheating as it was unfit for construction works
