Sinkholes may contaminate Bohol source of water


Residents in Bohol’s earthquake-struck areas are wary of their water source—they fear possible contamination brought about by reported sinkholes.

Tagbilaran parish priest, Rev. Father Val Pinlac, chair of the Church’s relief operations in Bohol, said that there is a possibility that the bedrock of their water source has been affected by the “holes” left by the 7.2-magnitude earthquake that struck on October 15.

“There are lots of holes and there is a possibility that the [bedrock of the underground aquifers]has been affected by the cracks,” he said.

Bohol, being one of the richest provinces in the country in terms of natural resources has its own water source, which is taken from the thirty deep wells with submersible pumps that operate at a daily capacity of 19, 000 cubic meters.

Water supply for Bohol is made available in Tagbilaran City and in the nearby municipalities on a 24 hour-basis with the completion of the Tagbilaran Water Supply Project.

However, the priest clarified that the water and electricity supplies had already been restored, a few days after the strong tremor occurred.

“Everything has been restored, supply of electricity and the water were restored,” he said.

Based on reports, the Mines and Geosciences Bureau (MGB) found over 100 sinkholes in the southern part of Bohol.

A sinkhole is a natural depression in a land surface linked to a subterranean passage, generally occurring in limestone regions and formed by solution or by collapse of a cavern roof.

On the brighter side, Pinlac said that the Boholanos are slowly recovering from the trauma caused by the earthquake.

Pinlac added that hundreds of quake victims have returned to their homes, but more than 3,000 families still live in tents that have been their temporary shelter.
