Abstract

Well water is used as a source of water for varios household needs, small, medium and large industries which are vulnerable to being contaminated by community waste and heavy metals. Lead (Pb) is the largest heavy metals winder in nature than other toxic metals. Pb accumulation in the body causes interference and damage to nerves, liver, kidneys, bones and brain. According to Republic of Indonesia Ministry of Education No.32 of 2017, states that maximum level of lead (Pb) heavy metal contamination in water for sanitation hygiene as raw water for dinking water is equal to 0,05 mg/L (ppm). The purpose of this study is to determin the levels of Lead metal content (Pb) in well water in the landfill area that meets the requirements or not according to PERMENKES/2017. The study was carried out using atomic absorption spectrophotometry method, where the sample must be wet destructed so that the metal element bonds whit the sample matrix are separated and obtained by metal in the form of free atoms. The results of destruction with concentrated HNO3 are then added by aquabidest to the boundary mark. The sample solution is the read at a wevelength of 283,3 nm. The result of the identification showed that all of the 5 samples of well water around the garbage dump of Putri Cempo Mojosongo Surakarta contained Lead (Pb). Level of Lead (Pb) of well water in the area of waste diposal, which is 7,285 mg/L (Well A); 6,513 mg/L (Well B); 6,369 mg/L (Well C); 6,283 mg/L (Well D); 5,739 mg/L (Well E). the maximum amount of Lead (Pb) that can be consumed by the community is based on RI PERMENKES No.32 of 2017, which 0,05 mg/L.
