Background: The poor sanitation and small numbers of households who own toilet in Sekotong regency may relate to the diarrheal events due to the fecal coliform contamination in drinking water.Aim: This paper aims to provide the concentrations of fecal coliform bacteria in shallow well waters and the factors associated to its growth.Method: Fifteen groundwater samples were collected from 5 shallow wells to provide the concentrations of total fecal coliform bacteria (FC), mercury concentration, inorganic nitrogen compounds (represent as ammonia, nitrate, and nitrite), total phosphorus (TP), dissolved oxygen (D), pH, and salinity. The concentration of the parameters was then compared to the safe limit set by World Health Organization (WHO).Results: The results indicated that the drinking water resources at the Sekotong regency were contaminated by coliform and mercury. One location with low mercury concentration was recorded with E. coli contamination. Residence, agriculture, and animal livestock were subjected as the sources of coliform contamination. Mercury concentrations may inverse the growth of FC. No apparent relationship was found between total phosphorous and inorganic nitrogen compounds to FC growth. However, we recognized the FC growth responded positively to the level of phosphorous in waters, but associated negatively to nitrate concentration. An inverse correlation was also found between coliform survival and salinity in this study. The pH range at 6.05 – 6.50 supported FC survival.Conclusion: The drinking water resources at the Sekotong shallow wells were contaminated by coliform and mercury. It is important for local government to inform drinking water protection and treatment.

Fecal Coliform Bacteria

Water is the main source for life and also the most severe substance caused by pollution. The mandatory parameters for determining microbiological quality of drinking water are total non-fecal Coliform bacteria and Coliform fecal (Escherichia coli). Coliform bacteria are a group of microorganisms commonly used as indicators, where these bacteria can be a signal to determine whether a water source has been contaminated by bacteria or not, while fecal Coliform bacteria are indicator bacteria polluting pathogenic bacteria originating from human feces and warm-blooded animals (mammals) . The water inspection method in this study uses the MPN (Most Probable Number) method which consists of 3 tests, namely, the presumption test, the affirmation test, and the reinforcement test. The results showed that of 15 drinking water samples 8 samples were tested positive for Coliform bacteria with the highest total bacterial value of sample number 1, 15 (210/100 ml), while 7 other samples were negative. From 8 positive Coliform samples only 1 sample was stated to be negative fecal Coliform bacteria and 7 other samples were positive for Coliform fecal bacteria with the highest total bacterial value of sample number 1 (210/100 ml).

ABSTRAKSungai Kuin merupakan anak Sungai Martapura yang yang bermuara di Sungai Barito. Sungai ini terdapat di Kota Banjarmasin, Kalimantan Selatan. Kejadian diare tertinggi di Kota Banjarmasin terjadi di bantaran Sungai Kuin, sehingga perlu dilakukan penelitian mengenai kandungan bakteri fecal coliform pada sungai ini. Penelitian ini bertujuan menganalisis jumlah kandungan bakteri fecal coliform di Sungai Kuin dan menganalisis cara mengatasi penurunan kualitas air Sungai Kuin akibat keberadaan bakteri fecal coliform. Data diambil sepanjang Sungai Kuin dengan panjang 3.909,00 m yang terbagi menjadi 20 segmen (10 segmen berada di bagian kanan sungai dan 10 segmen berada di bagian kiri sungai). Pembagian segmen berdasarkan panjang sungai per 390 meter, dengan sampel sebanyak 5 segmen yang mewakili segmen lainnya. Teknik analisis yang digunakan yaitu dengan menggunakan hasil uji laboratorium, perbandingan terhadap Peraturan Gubernur Kalimantan Selatan No 5 tahun 2007 dan referensi dari katalog informasi pilihan jamban sehat. Hasil penelitian menunjukkan bahwa kualitas air Sungai Kuin adalah berwarna kecoklatan, dan terkadang tercium bau terutama pada saat hujan turun. Jumlah rerata kandungan bakteri fecal coliform di Sungai Kuin adalah 210/100 ml pada saat pasang naik dan 780/100 ml pada saat pasang surut. Kualitas air Sungai Kuin tidak tidak memenuhi baku mutu air minum karena kandungan bakteri fecal coliform berada di atas baku mutu 100/100 ml.  Penurunan kualitas air Sungai Kuin dapat dilakukan dengan pembangunan jamban yang sesuai dengan lingkungan perairan pasang surut.ABSTRACTKuin River is a tributary of Martapura River, which flows into Barito River. It traverses Banjarmasin City, South Kalimantan Province. The highest diarrhea incidence in this city was found in the banks of Kuin River. Therefore, this research, focusing on fecal coliform bacteria in Kuin River, becomes necessary. Aside from analyzing the concentration of fecal coliform, it aimed to determine the strategies for dealing with the resultant water quality deterioration. The research data was obtained directly from Kuin River, i.e., 3.909 m in length. The river was divided into 20 segments (10 segments on each side of the river); hence, the length of each segment was 390 m. Afterwards, five segments were selected to represent the river. The research used laboratory analysis and, then, compared the analysis results with the Governor Regulation No. 5/2007 and other references, i.e., selected catalogs containing information of healthy lavatories. The results showed that the physical appearance of Kuin River included brownish color and foul-smelling water, especially during rainfall. The average concentration of fecal coliform bacteria in Kuin River was 210/100 ml during high tides and 780/100 ml during low tides. The water quality did not meet the standard for drinking water because the bacteria found in the river was above the allowed concentration, i.e., 100/100 ml. Water quality deterioration can be decelerated by constructing lavatories that are suitable for tidal environment.
