WATER QUALITY DETERIORATION

SEEPAGE FROM COAL REFUSE DISPOSAL FACILITIES IS OFTEN POOR IIN WATER QUALITY AND LEADS TO A DETERIORATION IN THE RE RECEIVING BODIES OF WATER. REMEDIAL MEASURES ARE USUALLY LIMITED TO TREATING THE DISCHARGE AS REQUIRED. THE PURPOSEDSTUDY WILL ADDRESS THE DEVELOPMENT OF FACILITY OPERATING TECHNIQUES WHICH WILL REDUCE THE POTENTIAL FOR LEACHATE FORMATION. INTERPRRETATION OF WATER QUALITY DATA COLLECTED FROM NUMEROUS COAL REFUSE DISPOSAL FACILITIES INDICATES THATTHE DETERIORATION OCCURS MAINLY WHEN WATER COMES INTO CONTACT WITH THE COARSE REFUSE PRODUCT. THE APPROACH S SUGGESTED FOR FURTHER INVESTIGATION UNDER THE PROPOSED STUDYWILL FOCUS ON IMPLEMENTING TECHNIQUES WHICH WOULD RESULT IN A CONSIDERABLE LOWERING OF THE PHREATIC LEVELS IN BOTH THE COARSE AND FINE REFUSE PORTIONS OF THESE WASTE DISPOSAL FA FACILITIES. BY REDUCING THE WATER TO COARSE REFUSE CONTACT, IT IS ANTICIPATED THAT SIGNIFICANT IMPROVEMENTS IN WATER QUALITY CAN BE ACHIEVED.
