Pengaruh Limbah Cair Industri Pelapisan Logam Terhadap Kandungan Cu, Zn, Cn, Ni, Ag Dan SO4 Dalam Air Tanah Bebas DiDesa Banguntapan, Bantul

This study aimed to investigate the effect of metal plating wastewater industry in the village Banguntapan the content of Cu, Zn, CN, Ni Ag and SO4, the free on-site groundwater industry and the possibility of contaminated zone in the downstream industry. The research was conducted by collecting secondary and primary data. Sampling was done in purpose sampling by dividing the study area on 3 zones based on the location industry. Zone1 is zone at locations upstream industry is considered as zone control. Zone 2 is a zone that is an area of industrial activity. Zone 3 is downstream industry zone in the determination of the point of the sample conducted empirical Point Count System developed by Le Grand. The results showed that the metal plating industry wastewater has increased the content of Cu, Zn, CN, and Ag industry in the groundwater at the site, but still meet Water Quality Standards Water Materials Group B. The content of Zn in the groundwater at the possibility of contaminated zone at downstream industry has increased, because the content of Zn in the metal plating industry wastewater
