The damage further goes on due the fact that the owners of the quarry permit the dumping of cement and lime and other wastes down in the valley, probably while washing their machines on a routine basis.
As a result there is a sediment of cement/lime at the bottom of the valley which is prohibiting plants from growing as well as these compounds are by themselves toxic to many lifeforms.
I am reporting this in the forum so that maybe some one responsible (such as the MEPA) will control better such quarries, and perhaps stop giving permissions for new quarries near valeys and natural resources.
