ANALYSIS OF IRON (FE), NITRATE (NO3)– AND E. COLI BACTERIA IN WELL WATER SAMPLE OF TOMBANG, KELURAHAN KALABAHI TENGAH, ALOR-NTT
The purpose of this study is to analyzed water quality in shallow well water sample of Tombang, Kelurahan Kalabahi Tengah, Alor Regency-NTT. Water samples were collected from five sources of shallow well water based on Global Positioning System. The parameters studied were physical properties (temperature, odor, taste) chemical properties (iron (Fe), nitrate (NO3)-) and biology aspect (microorganism presence) contained in shallow well water sample of Tombang has been carried out on March 2015. The observed values of various physicochemical parameters of water samples were compared with standard values recommended by Permenkes No. 492/ Menkes/ Per/ IV/ 2010. Results showed chemical properties (temperature, odor, taste) are below that recommended level. The amounts of iron (Fe) were present higher than the permissible limits water standard quality recommended and nitrate still below. In five water samples obtained from artesian water sources that have been tested showed a positive result of e-coli bacteria.
