Status Mutu Air Sumur Gali di Dusun - Dusun Sekitar Tempat Pemrosesan Akhir Sampah Ngronggo Salatiga (Kajian Berdasarkan Kandungan Logam Berat (Pb dan Cu) dan Bakteriologis)

Abstract

The use of controlled landfill system in the Ngronggo Dump Site Salatiga in the end of 2012 should be able to reduce groundwater contamination which had been occurred in these place. Therefore in July until December 2014, a study to determine water quality and heavy metal content of lead (Pb2+) and Copper (Cu2+) in the dig wells water of the villages near the Dump Site Ngronggo were conducted. The water samples were taken by disproportional stratification sampling method and measured the heavy metals (Pb2+ and Cu2+), physic-chemical and bacteriologic parameter. The data were compared with Government Regulation No.82 of 2001 and using STORET method to determine the water quality. The results at this study showed that out of 88 dig wells water distributed across 12 villages near the Dump Site Ngronggo, 88% had a Cu2+ content exceeded the quality standards and 72% exceeded the minimum limit of Pb2+ on the water. This results confirm the water quality determination which considered as a poor quality. This study shows that groundwater contamination still occur despite the use of controlled landfill system and its application is still not able to handle the groundwater contamination occurred in the Dump Site Ngronggo Salatiga
