Drinking water is one of the main components that make up 70% in the human body. National Socio-Economic Survey or Survei Sosial Ekonomi Nasional (Susenas) conducted by BPS in March 2023 stated that there are 40.64% of households in Indonesia who depend on refillable water contained in gallons as a source of their drinking water. Refillable drinking water in Indonesia is usually distributed using polycarbonate (PC) or polyethylene terephthalate (PET) gallons which are plasticbased containers that contain many chemical compounds and have the potential to migrates to drinking water, including Bisphenol-A (BPA). There are several factors that are suspected to affect the migration of BPA to drinking water, namely storage temperature, gallon material, pH of drinking water, and gallon usage period. To ensure this, a BPA migration study was conducted on drinking water in gallon containers that were given two treatments. First, gallon are stored in a room that is unexposed to sunlight. Second, the gallons were stored outdoors exposed to sunlight for 7 hours for 7 days. The results showed that there was a concentration of BPA in drinking water contained in gallons with concentration about 0.006 ppm in indoor gallons and 0.006 to 0.051 ppm in gallons stored outdoors. In addition, the risk quotient (RQ) was analyzed to determine the potential hazards due to the migration of BPA in drinking water. Based on reference values from BPOM and US EPA, it is known that the RQ value is still below 1. Even so, the migration of BPA in drinking water must still be monitored because it can cause health problems, such as heart disease, reproductive system problems, and hormonal disorders.
