<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>

A simple, fast, and sensitive method for determination of total arsenic in drinking water sample by ETAAS after solid phase preconcentration has been developed. The dead biomass ofA. nigerloaded on activated charcoal has been applied as bioadsorbent for preconcentration step. The effects of parameters such as pH, type and concentration of eluent, biosorption time, sample volume, and effect of interfering ions have also been studied. Under the optimum condition, the enrichment factor of 10 for the analyte has been obtained. The accuracy of the method has been investigated by the recovery of spiked standards and the recovery percents between 99 and 102% have been achieved. Total amount of arsenic was determined by reducing As (V) to As (III) with potassium iodide (KI) and ascorbic acid in HCl solution. Under the optimum conditions, for 400 mL of drinking water samples, the detection limit (3σ) and linear range were achieved 1 ng/mL and 5–100 ng/mL, respectively. The relative standard deviation for ten determinations of a spiked sample with concentration of 10 ng/mL As was 3.2%.

Determination Of Copper

The aim of the study was to determine the levels of lead, cadmium, arsenic copper and iron in 25 water samples collected from across Kogi State. Atomic absorption spectrometry was used in the determination of copper, iron, lead and cadmium while UV-visible spectrophotometer was employed in the determination of arsenic, based on the formation of Molybdoarsenate. The ranges of mean values obtained for the heavy metals are: Arsenic (0.0014to 0.0252 mg/L), Copper (0.0013to 0.0095 mg/L), Lead (0.0001to 0.024 mg/L), Cadmium (0.003 to 0.072 mg/L) and Iron (0.0068 to 0.1242 mg/L). The results revealed that the River, Stream and Tap water sampled were contaminated with Arsenic (As), whereas, the levels of Fe, Cu and Pb were within the recommended limit set by WHO and NAFDAC. Though the level of cadmium (Cd) falls within acceptable limit in some of water samples, its high concentration in Isanlu should attract the attention of the authority in this area in curbing the growing threat.
