REMANENT LAKES FORMED THROUGH THE WORK OF KAOLIN EXPLOITING FROM AGHIRE U (CLUJ COUNTY)

Fairly widespread in Romania, remanent lakes represents a great potential for recovery, provided it is taken into account and on investment, often minimal. Lakes of Aghiresu developed on exploitation of kaolin sands, are very dynamic in time and space. The permanent lakes are very important (the "Blue Lagoon" case), which provides not only an unique landscape but also a mineralised water with a great potential. Measurements and observations made since 2003, including physico-chemical analysis, have allowed detailed study of these lakes. It was possible to develop conclusions, which related to studies of water quality can be the start of projects and investment recovery in an monoindustrial area, strongly affected by the reduction by almost ceasing of mining activity.
