Effect of Fly Ash Disposal on Ground Water Quality near Parichha Thermal Power Plant, Jhansi: A Case Study

Abstract

Thermal power plant generates a huge amount of fly ash on combustion of coal which is becoming a major environmental issue. Thermal power plants are greatly facing a fly ash management problem. Open dumping of fly ash can deteriorate the groundwater quality by runoff. In the present investigation, the ground water samples were collected from nearby areas of Parichha Thermal Power Plant at six locations during the period of Jan 2014 to May 2014. The samples were taken to the laboratory and analyzed for physico-chemical properties and heavy metal content. The physico-chemical analysis was done for the parameters like pH, Turbidity, Temperature, Electrical Conductivity, Alkalinity, Total Dissolved Solids, Total Hardness, Calcium Hardness and Magnesium Hardness. The concentration of Turbidity, EC and Alkalinity was exceeding the standard at all locations and shows that the groundwater of the area is not fit for drinking. The ground water samples were also analyzed for the presence of lead and cadmium and it was found that lead was exceeding the limit although cadmium was found within the limit.

Effect of Fly Ash on Water Quality as Influenced by Distance in Four Radiant Directions From Rayalaseema Thermal Power Plant (Rtpp)

“…The temperatures near RTPP ranges from 22 °C and 43°C which raises the alkalinity of water because at that temperature the solubility of CO 2 reduces. Similar reports were made by Kanchan et al (2015).…”

Bioaccumulation and potential sources of heavy metal contamination in fish species in River Ganga basin: Possible human health risks evaluation

“…The high volume of alkaline may also be due to the increase of free (CO 2 ) in the Ganges River, which ultimately results in the rise of alkalinity at the Mirzapur site (Table 2). This condition may also occur because of the presence of strong bases such as carbonates, bicarbonates, and hydroxides in the water body [50]. The high values of alkalinity may also be due to a increase in free CO 2 in the River Ganga by which bicarbonate ions are converted into carbonate, which ultimately results in an increase in alkalinity level at Mirzapur and Varanasi sites compared to Kanpur and Allahabad.…”

Environmental Stress and Health Vulnerability Assessment around Kolaghat Thermal Power Plant, West Bengal

“…Jena (1993) explored that the fly ash from Thermal power plants is changing soil upper layer structure, PH level, soil fertility [14]. According to studies, the amount of metals like zinc, copper, magnesium, and iron in fly ash from thermal power plants increases with the proximity of the source and decreases with distance [15]. By studying the literature, the research gaps have been identified as the following: Numerous pieces of research have mostly focused on the effects of only one environmental stressor, such as fly ash or radionuclide, with one environmental media of concern, such as groundwater, ambient air quality, soil, or river sediments.…”
