<p><em>Refill drinking water production is now rapidly increasing in several regions in Indonesia, including Purwokerto. According to the Regulation of Health Minister of the Republic of Indonesia (Permenkes) Number 492/Menkes/Per/IV/2010, heavy metal is one of the parameters of drinking water quality which has adverse impacts on human health. In this study, Arsenic (As) and Cadmium (Cd) would be studied. Atomic Absorption Spectrometry (AAS) Method was used to find As and Cd concentration in refill drinking water samples. The results showed that only one sample containing As from five samples was collected, but there is being safe for drinking according to Regulation of Health Minister of the Republic of Indonesia (Permenkes) Number 492/Menkes/Per/IV/2010. Meanwhile, Cd was not detected in samples. It can be concluded that refill drinking water samples that were taken from several depots in Purwokerto City are being safe for drinking.</em></p>

AbstractThe use of an electrogalvanic device for scale neutralisation is descibed in this paper. Physico-chemical analyses were performed before and after the treatment. The results were compared with those obtained by using magnetic water treatment device. By measuring some individual parameters and the implementation of chemical analysis, the satisfactory functioning of the electrogalvanic device was demonstrated. The quality of drinking water did not change much after the water treatment method. The results of determination of calcium carbonate saturating index showed that the raw drinking water is in carbonate equlibrium as well as both treated water samples. The calcite/aragonite ratio was studied by means of microscopy and X-ray powder diffraction. Inspection of crystals formed during the experiments with microscopy indicated that aragonite crystal structure of the precipitates prevailed over the calcite stucture. The diffractograms showed that the share of aragonite increased after using the electrogalvanic device compared with raw drinking water samples where the share of calcite was higher.
