The study of general geology and geochemistry of water discharge in kg Sat, Tanah Merah, Kelantan was conducted in area of approximately 25km2. The objective of the study area was to produce the geological map of the study area with scale 1:25000. For geochemistry the objective is to identify the water quality and the heavy metal concentration level of the kg. Sat river base on INWQS guideline for Malaysia This study was conducted to identify the effects of sand mining on water quality and increase the heavy metals in the river. The five samples was taken and at the same time the water quality was measure in situ using HATCH YSI 556 multi parameter and for heavy metal concentration was measure at the laboratories using chemical. Then the sample concentration of heavy metal was identify using HACH DR 900 colorimeter at laboratory. Then the result of the water quality and heavy metal concentration level was compared with the INWQS guideline for Malaysia to classify its class and to determine the water river was safe or not for daily use. From all the result shows that the water quality of the river was in controlled condition which is can be used for daily life but need treatment to reduce the turbidity and another particle. The heavy metal concentration was still at normal level and still safe to use. This research also can conclude that the water quality and heavy metal concentration level in the river was not causes by the sand mining alone. It is also caused by other factors that contribute to the degradation of water quality and increase the concentration of heavy metals.
