It was marked by high turbidity and declining of organism in that river. The choice of determining the content of heavy metal Pb or lead because we know that gold processing is not only used by mercury but also used by lead and cadmium to bind gold. The three metals are used to bind the gold and separate it from soil and stone in from sulfide.. This research used survey method with purposive sampling based on the rise location of PETI activities.
