Surface water quality analysis has been studied to determine the different ion concentrations in the waters on the river Kr. Teunom and the river Kr. Ligan of Aceh Jaya regency. The results of the analysis of the water quality of the river show were physically the water quality of the river Kr. Teunom and Kr. Ligands are still following quality standards. Based on chemical parameters, the water quality of the river Kr. Teunom and Kr. Ligands, in general, are found in a low level of heavy metals such as Hg, Mn, Pb, As, Cd, and Cr in water. Cyanide levels in all samples of the river water are following the quality standard PPRI No. 82 of 2001 Class I and regulation of the Minister of Health Number: 492/Menkes/Per/IV/2010 concerning drinking water quality requirements.
