High Concentrations

In order to evaluate the impacts of metals mobility from fly ashes on surface water quality, the dissolved metals concentrations in the stream and pond waters nearby fly ash piles were investigated at the thermal power plant regions in central Guizhou Province, and batch leaching or column leaching tests for the fly ashes were performed. The results shown that the most mobile of the metals leached were Cu, Cr, Pb and Cd from fly ashes and the concentrations of the metals in leachate solutions increased with the amount of fly ashes, and high concentrations of Pb (0.040~0.886 mg L−1), Cr (0.025~0.315 mg L−1) and Cd (0.007~0.052 mg L−1) in the leachates from fly ashes, and then there is an mobility of dissolved metals to the surface waters impacted by the runoff or leaching water. In thermal power plant areas, the concentrations of Pb, Cr and Cd in the stream waters and the pond waters nearby fly ash piles were 0.024~0.374 mg L−1, 0.030~0.212 mg L−1 and 0.014~0.035 mg L−1, respectively, as indicated by high concentrations of Pb, Cr and Cd, making it unsuitable for human drinking, suggesting a environmental problem of runoff or leaching water from fly ash pile in those areas.

The Impact

This article investigates the impact of anthropogenic activities on an important surface water from physico-chemical, chemical and microbial perspectives. The surface water, referred to as Blesbokspruit is in the West Rand District of South Africa. Potential impactors include wastewater treatment plant, mines, farmlands and informal settlements. Water samples were collected from nine purposively selected sampling points and analysed in 2014. The mean values of analysed variables across sampling sites and periods ranged from pH: 7.4-8.4; EC: 93.0 - 146.6 mS/m; TSS: 11.3 – 39.0 mg/L; TDS: 590.3 - 1020.3 mg/L; COD: 15.6- 34.8 mg/L. Those for anions varied from NO3-: 0.2- 2.1 (mg/L) N; PO43- : 0.4-0.9 mg/L and SO42-: 118.6 - 379.5 mg/L. The metallic variables ranged from As: 0.01-0.06 mg/L; Cd: 0.02-0.06 mg/L; Fe: 0.04-0.73 mg/L; Cu: 0.02 – 0.05 mg/L and Zn: 0.05 – 0.15 mg/L. The Faecal coliform varied from 15.9-16878.5 cfu/100 ml; Total coliform: 92.9-430294 cfu/100 ml and HPC from 4322.5-39776 cfu/1ml. Detection of toxic metals and pathogenic organisms above target safety limits indicate unsuitability of the water for domestic use with impact on the health of aquatic ecosystem. The study generally revealed the impact of anthropogenic activities on the surface water quality.

Some important physico-chemical properties of surface water around DEPZ industrial area, Savar were studied to evaluate the water quality. Seven water samples were collected from major waterbodies of DEPZ industrial area. The value of Physico-chemical parameter such as Temperature (57-24°C), pH (12.45-7.58), EC (12400-2060 ?s/cm), BOD5 (895-63.19 mg/L), TSS (2170-435 mg/L), TDS (6840-1036 mg/L), Turbidity (89.55-32.16 mg/L) and Salinity (7.1-1.0 ppt) were highest in the point source (W1) and began to decline as the waste dispersed through the nearby waterbodies (W2-W7). The result revealed that all the chemical constituents, except a few, were beyond the recommended limit for various uses. The lowest content of DO (0.10 mg/L) and highest content of BOD5 (895 mg/L) in point source waterbody indicate that the industries were releasing large amount of oxygen demanding organic wastes which subsequently affected all the studied waterbody. Among metal content of the study area, the value of Fe (1.331-0.443 mg/L), Zn (0.308-0.134 mg/L), Cu (0.244 0.127 mg/L) and Cr (0.615-0.055 mg/L) were gradually decreased from point source to the remote area. Point source (W1) waterbody had the highest concentration of Cr (0.615 mg/L) which exceeded the safe limit for industrial wastewater. This may be due to various chrome agent used in dyeing purposes. Anionic parameters like F- and PO4 3- were at intolerable limit in some waterbody. The coefficient of correlation analysis among physicochemical properties indicated that all the parameters had significant contribution to pollute the water. The correlation between DO and pH was strongly negative (r=-0.995**). Fe showed positive significant correlation with Zn, Cu and Cr. There was a significant positive interaction of PO4 3- with Cl- and NO3- in case of water quality deterioration. The above findings showed that the surface water around DEPZ industrial area was highly polluted by the industrial activities and was harmful for life.
