Abstract

Sinabung mountain in North Sumatra Province has been erupted since August 2010. The post-eruption conditions caused changes in land cover and had direct impact on the surrounding area. The community used drinking water sources from springs and wells which have been exposed to metals contained in volcanic ash eruptions. This study aims to analyze the chemical quality of community drinking water sources. Amount 21 samples of drinking water sources representing the direction of volcanic eruption were analyzed in the laboratory using Atomic Absorption Spectrometry method. Each sample point was analyzed by using the Inversed distance weighted (IDW) method. The results of the laboratory showed that Fe concentrations exceeded the environmental quality standard, while other metals still met the requirements for drinking water quality. The order of metal concentration in drinking water Fe> Mn> Cd> Pb. The results of correlation between distance and Fe concentration obtained value r = 0.083.
