“…It is another water quality parameter that measures the ionic condition of water and is affected by temperature, the concentration of impurities, and the mobility of ions [ 36 ]. The lowest value of EC was 137μS/cm in Tukure and the highest value was 285μS/cm in Setumari.…”

This work helps to identify the source of pollution in water and characterize the water quality which is essential to water management for sustainable development. Therefore, the main objective of this work is to evaluate the spatial distribution of the water quality of Ratuwa river and its tributaries. The water samples were collected from six discrete sampling locations and fifteen parameters were tested using respective well-calibrated equipment and standard APHA methods. The physicochemical analysis, water quality index, and correlation matrix method were employed to evaluate the spatial variation of the water quality of Ratuwa river. Turbidity was the most polluting factor in river water. The results showed the spatial variation of the water quality index (WQI) from 39.3 to 70.5, which fell in the range of “good” to “poor” water quality status. None of the water samples was either “excellent” or “unsuitable for drinking.” The water quality was “Poor” upstream and downstream of Ratuwa river due to the high value of turbidity. Chaju river was found to have unpolluted whereas Dipeni river was slightly polluted due to domestic and municipal wastes. Hence, the deterioration of water quality can be attributed to natural and anthropogenic sources.

“…Compounding the pollution crisis is about 3500 illegal hutments that have been built along the banks of the river, which also discharge large volumes of untreated DWW. Critically, people living in the vicinity of the Koovam River rely on groundwater sources for daily use [ 75 ]. Four DWW discharge points along the densely populated Koovam River banks were chosen for collection of DWW samples while HWW samples were collected from four different discharge points of the Government General Hospital, where about 12,000 to 15,000 outpatients receive treatment daily.…”

The discharge of untreated hospital and domestic wastewater into receiving water bodies is still a prevalent practice in developing countries. Unfortunately, because of an ever-increasing population of people who are perennially under medication, these wastewaters contain residues of antibiotics and other antimicrobials as well as microbial shedding, the direct and indirect effects of which include the dissemination of antibiotic resistance genes and an increase in the evolution of antibiotic-resistant bacteria that pose a threat to public and environmental health. This study assessed the taxonomic and functional profiles of bacterial communities, as well as the antibiotic concentrations in untreated domestic wastewater (DWW) and hospital wastewater (HWW), using high-throughput sequencing analysis and solid-phase extraction coupled to Ultra-high-performance liquid chromatography Mass Spectrometry (UHPLC–MS/MS) analysis, respectively. The physicochemical qualities of both wastewater systems were also determined. The mean concentration of antibiotics and the concentrations of Cl−, F− and PO43 were higher in HWW samples than in DWW samples. The phylum Firmicutes was dominant in DWW with a sequence coverage of 59.61% while Proteobacteria was dominant in HWW samples with a sequence coverage of 86.32%. At genus level, the genus Exiguobacterium (20.65%) and Roseomonas (67.41%) were predominant in DWW and HWW samples, respectively. Several pathogenic or opportunistic bacterial genera were detected in HWW (Enterococcus, Pseudomonas and Vibrio) and DWW (Clostridium, Klebsiella, Corynebacterium, Bordetella, Staphylocccus and Rhodococcus) samples. Functional prediction analysis indicated the presence of beta-lactam resistance, cationic antimicrobial peptide (CAMP) resistance and vancomycin resistance genes in HWW samples. The presence of these antibiotic resistance genes and cassettes were positively correlated with the presence of pathogens. These findings show the risk posed to public and environmental health by the discharge of untreated domestic and hospital wastewaters into environmental water bodies.

“…Berdasarkan hasil analisis laboratorium pada 50 sampel air tanah, nilai kadar pH pada sampel berkisar antara 5,32-7,98 dengan rata-rata 6,93. Faktor yang mempengaruhi nilai pH tersebut kemungkinan dipengaruhi oleh faktor alami yaitu sifat kimia batuan yang dilewati aliran air tanah serta pengaruh dari air meteorik (Elangovan and Dharmendirakumar, 2013). Sesuai dengan peraturan Menteri Kesehatan Nomor 492 Tahun 2010 untuk keperluan air minum, dari 50 sampel laboratorium dan hasil pengukuran di lapangan, secara umum memenuhi standar baku untuk digunakan sebagai air minum, hanya beberapa titik mata air memiliki kadar pH di bawah ketentuan yang diperbolehkan dalam Peraturan Menteri Kesehatan yaitu antara 6,5-8,5 seperti titik minatan di Krempong (MA 23), Bejen (SD 62), Kedungboto (MA 33, dan SD 63), Kemiriombo (SD 22), Candigaron (MA 49), Getasan (MA 65), Mento (SD 1), Kertosari (SD 6), Banyuringin (SD 58), dan Tlogopucang (SD 32), sehingga mata air yang memiliki pH dibawah 6,5 harus melalui proses lebih lanjut jika akan digunakan untuk air minum.…”

Hydrogeological Mapping for Analyzing of Groundwater Conservation Zone in Sumowono Groundwater Basin, Central Java Province

Groundwater management at groundwater basins Sumowono needs to be done because of the increasing development of the area. This research is oriented to analyzing groundwater conditions, compiling groundwater conservation zones, and explaining conservation zones' suitability with spatial maps. The method used is mapping hydrogeological conditions such as surface observation of rock types, inventory of hydrogeological points of interest, knowing the patterns and directions of groundwater flow, groundwater utilization, and groundwater sampling to measure the degree of acidity and electrical conductivity. From the mapping results, it is found that the lithology is composed of tuffaceous sandstones and volcanic breccias. Based on the free groundwater table analysis, the free groundwater flow pattern follows the topographic slope, flowing from the high topography on the south and southeast sides to the low topography on the north side of the area. The utilization of groundwater is used for irrigation, domestic and fishery purposes. Measurement of groundwater samples' quality for the degree of acidity is between 5.32-7.98 while the electrical conductivity is between 36-550 µS / cm, and the level of damage due to groundwater utilization is included in the safe zone. The groundwater conservation zone consists of recharge areas and spring protection zones. The result of overlapping between the groundwater conservation zone and the spatial plan map shows suitability as a protection zone.
