Assessment of Groundwater Quality in A Selected Area of Bangladesh

Abstract

Abstract:A study was conducted to evaluate the groundwater quality at Phulpur thane of Mymensingh district in Bangladesh. Water samples from 14 deep tubewells were analyzed for pH, EC, TDS, Na + , K + , Ca ++ , Mg ++ , Fe, P, B, NO 3 -N, SO 4 G, ClG, CO 3 G and HCO 3 G. In addition SAR, SSP and RSC were calculated following standard equations. The range of EC was 180-380 μScmG 1 and SAR 0.22-0.80 and these two parameters indicated that three samples were in 'low salinity-low alkali' and 11 were in 'medium salinity-low alkali' hazard class. There was no chloride toxicity in the area. The presence of SO 4 G, NO 3 G and P were negligible. As regards boron and SSP, all waters were of 'good' to 'excellent' class. In respect of TDS all were 'fresh water'. On the basis of RSC values all samples were of 'suitable' class. As a whole, groundwater of the area can safely be used for long-term irrigation. But some of those may not be suitable for drinking and industrial uses in consideration of Fe concentration, TDS and pH values. Among the quality determining factors SSP and SAR were highly correlated where correlation coefficient was 0.97.

Physicochemical and microbiological quality of tanker waters in Bengaluru urban for safe water supply

“…Turbidity levels of the water samples were within the range of recommended levels. Water containing TDS less than 1000 mg L -1 could be considered good enough both for drinking and irrigational purposes [17,18]. In this study, most of the water samples tested were within the limits except SL-46, SL-48 and SL-18 which recorded 5200, 2400 and 1600 mg L -1 respectively.…”

Determination of Some Heavy Metals from Ground Water Samples Obtained from Selected Motor Parks in Kaduna, Nigeria

“…The total dissolved solids (TDS) of samples collected from the sampling sites were all within the WHO permissible limit of 1000 mg/l with the exception of Abuja junction (BW) which is 1620 mg/l. Water containing TDS less than 1000 mg L-1 could be considered to be "Fresh water" and good enough both for drinking and irrigational purposes, as this would not affect the osmotic pressure of soil solution [6,13]. Table 2 shows that the mean concentrations of cadmium in borehole and well water samples obtained from selected motor parks and was found to be above the permissible limit of 0.003 mg/l given by NSDQW, (2007) and WHO, (2008) with an exception of sabo garage with mean concentration (0.002 mg/l).…”

Evaluation of laterite as filter media to remove arsenic from groundwater

“…51 It's reported that the range of particulate matter or suspended particles was consistently found that around 350 mg L -1 . 52 Globally these particles also came into the low range in contrast with dissolved matter concentrations, which are tested in numerous hundreds of mg/L. It reported that if the water contains TDS less than 1000 mg L -1 then it could be freshwater and well enough for both drinking and irrigational purposes.…”

“…It reported that if the water contains TDS less than 1000 mg L -1 then it could be freshwater and well enough for both drinking and irrigational purposes. 52 An important water quality parameter, NO -3, was also studied during the filter test. Overall, the concentration of the NO -3 was within the permissible limits, but Filter 2 showed extreme variations as compared to Filter 1 which remained almost consistent throughout the experiment.…”
