AbstractThe effect of physical and biological qualities of wells after submergence was assessed following December 2014 flood in Kelantan. Studies were carried out on a total of 65 wells from 13 stations around Kelantan River basin in which the wells’ water were sampled for pH, total dissolved solid (TDS), turbidity and microbial contamination. About 95% of the well showed to be contaminated, 7 out of 65 samples (11.1%) showed TDS values >400 μS·cm−1; and 19 samples (29.2%) recorded turbidity beyond 7.0 NTU. Statistical non-parametric tests carried out on independent groups showed that the status of well contamination was neither determined by both degree of submergence nor by the geographical location. Also the physico-chemical parameters are independent of flood inundation. However, TDS and turbidity values changed based on geographical location, at p < 0.05. Well from estuary recorded higher TDS (241.2 μS·cm−1 ±159.5 SD) and turbidity (8.04 NTU ± 6.53 SD) compared to those from inner basin (TDS at 156.3 μS·cm−1± 88.9 SD; turbidity at 2.90 NTU ± 2.46 SD), respectively. The flood water had played significant role in the transmission of existing contaminant, and most of the wells were unsafe for drinking. We concluded that the degree of flood submergence does not necessarily determine the severity of the well contamination in Kelantan, but the existing contamination may exacerbate further the potential risk during post flood period.

Water quality is an index of health and well being of a society. The pollution of water bodies is one of the areas of major concern to environment. In the present investigation an attempt has been made to evaluate the physical, chemical and microbiological parameters of Jhajjar rivulet of J&K. The study has been carried out by taking water samples at three different sites of the rivulet i.e. site 1, site 2 and site3. During the study, the physico-chemical parameters like pH, temperature, colour, total hardness, BOD, COD, DO, TDS and TSS in the water samples were studied. In microbiological examination, the presence of coliform in the water samples were studied.  It has been observed that there was a pollution load mostly at site 3 and slightly at site 2, it may be due to the release of huge quantities of sewage, effluent and manmade activities at the respective sites but the water from all the sites was found free from microbial contamination. It was concluded that water at site 1 is suitable for drinking as compared to site 2 and site 3 of the rivulet.

AbstractOligochaeta samples were collected from seven lakes (2 natural and 5 non-natural) of Ceyhan River basin during the summer and autumn seasons of 2014. The Ceyhan River basin is located in the south-eastern Anatolia region in Turkey. Lakes Gölbaşı and Azaplı are located in a protected area. Some physico-chemical parameters of surface water were measured in situ. Sampling for oligochaetes was conducted by using both hand-nets and an Ekman Birge grab sampler, with samples obtained from different depths. Oligochaetes represented the dominant group of the total benthic macroinvertebrates in samples, with the exception of samples collected from Ayvalı Dam lake. A total of 11,293 oligochaete specimens were sorted from samples collected from these lakes, from which 14 species belonging to 2 subfamilies (Naidinae and Tubificinae) were identified.

The Impact

Considering Ganga River as one of main Holy River in India, millions of people throng to the river to have a holy dip, Aachman (Mouthful of holy water) and cleanse themselves of sins. Magh Mela is a great festival to take place in bank of Triveni (Sangam) at Allahabad and runs more than one and half month, when millions of pilgrims from different regions in India go there for taking a holy bath in Sangam of Ganga. Thus, the bathing in the river during Magh Mela leads to high pollution of the river in comparison to other days such as normal bathing days. This study focused on the water quality status from some selected physico-chemical parameters of River Ganges and the impact of Magh Mela as well as the variation in the river’s flow rate. Results indicate that the pollution load was alarmingly high and the flow of the Ganga had been very poor. Further, the study found that the water was not fit for bathing during the 2012 Magh Mela.

The increase in world’s population has led to increase in waste generation and is a source of concern for stakeholders across the world. These wastes end up in dumpsites which undergo different stages of decomposition thereby producing Leachate which have a tendency of polluting groundwater. This study assessed biodegradability and Leachate Pollution Index (LPI) of dumpsite relative to its age. Three dumpsites Orile (O), Solous 3 (S3) and Solous 1 (S1) dumpsites with different ages: – less than 5, between 5-10 and greater than 10 years old respectively were studied. Leachate samples were collected from each dumpsite; Physico-chemical parameters: pH, chloride, Iron, Zinc, Arsenic, Total nitrogen, Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD5), Total Dissolved Solid, Electricity Conductivity and heavy metal: Lead, Chromium and Copper were analysed to determine the LPI while BOD5/COD was determined to ascertain the level of biodegradability of the dumpsites. The BOD5/COD results for O, S3 and S1 leachates were in the decreasing order of 0.37, 0.29 and 0.21 respectively while LPI results for: O, S1 and S3 leachate were 10.00, 11.20 and 15.68 respectively which were above the standard limit of 7.38. The results showed that O and S1 dumpsite leachate had least and highest sign of biodegradability respectively. The LPI result showed that O and S1 dumpsite leachates had the highest and the least pollution potentials respectively. Leachate from dumpsites less than 5 years has higher pollution potentials and lesser biodegradable than leachates from dumpsites more than 5 years. Leachate from O dumpsite will impact negatively on groundwater quality than leachates from S1 and S3 dumpsites. The age of a dumpsite leachate determines its pollution potential and biodegradability.

Assessment on the level of pollution of Turag river water was performed by measuring various physico-chemical parameters. Water samples were collected five times in a year both dry and rainy season at five different locations: Bishwa Ijtema field, Tongi Bridge, Kachare ghate, River side of Dhaka Dying and Effluent of Dhaka Dying. Most of the measured parameters exceeded the permissible limit of standard level. Values for different parameters at different points were recorded such as Temperature (T): 23.9 to 31.2°C, pH: 7.2 to 10.1, Salinity: 64 to 933 ppm, Total dissolved solid (TDS): 90 to 1244 ppm, Electrical Conductivity (EC): 135 to 1856 µs/cm, Dissolve oxygen (DO): 0.5 to 3.6 mg/L and Chemical oxygen demand (COD): 220 to 1170 mg/L. The concentration (ppm) of heavy metals were also observed such as Chromium (Cr) 0.0339 to 0.6334, Cadmium (Cd) 0.0068 to 0.0170, Nickel (Ni) 0.1282 to 0.6207, Cooper (Cu) 0.0148 to 0.1703 and Zink (Zn) 0.0366 to 0.1890 at dry season. The values of different parameters determined are above the safe limits recommended by DoE, EQS and WHO. Therefore, it can be concluded that water relieved from selected locations were not suitable for human consumption during the period of experiments.Bangladesh J. Sci. Ind. Res. 51(3), 193-202, 2016
