Working in oil and gas industry i remember one of top geologist in my company once said 8 years ago.

"Sapa2 geologist or reservoir engineers yg beli rumah dekat selayang and batu caves is stupid. Carbonate bedding wise, the distance of ground surface and top of carbonate over there is one of the closest distance around klang valley"

Basically acid rain will dissolve carbonate especially limestone and its just disaster waiting to happen.
