Study of Effects of Leachate

Leachate in landfill can be defined as a liquid that passes through a landfill a has extracted dissolved and suspended matter from it. Leachate generation is a major problem for municipal solid waste (MSW) landfills in many countries and it causes significant threat to surface water and ground water. To find the effect of leachate in the ground, ground water sample was collected from the surrounding areas of 1 km radius away from Kodungaiyur landfill and the samples were tested for various parameters such as colour, turbidity, pH, conductivity, total dissolved solids, total hardness, calcium, magnesium, chloride, sulphate, nitrate, fluoride, potassium, COD and BOD. Eight samples were collected from 1km away were collected. The parameters were compared with IS 10500:2012. The analysis helps us to understand how much the ground water is affected by the percolation of leachate. Keywords: Leachate, Hardness, Chloride, TDS, BOD, and COD

Assessment of Heavy Metals Contamination in Ground Water around Industrial Region in Nadar Ganj Lucknow

Nadar Ganj being a prominent industrial area of Lucknow Uttar Pradesh, owes its significance to diverse group of industries. this study is to investigate the pollution of bore water in the industrial region in Nadar Ganj industrial area in Lucknow. The contamination of groundwater is one of the most important environmental issues in the world. Among the various pollutants that affect water resources, pollutants containing heavy metals are particularly important due to their high toxicity, even at low concentrations. The percolation water picks up a large number of heavy metals and reaches the aquifer system and contaminates ground water. five ground water sample were collected from the study area in February 2021.the heavy metals (Pb, Fe, Cu, Cr, Ni).

Study and Analysis of Ground Water Quality

Today’s drastic issue takes place due to human behavior in our environment. And we are discussing about the issue of water pollution and harmful substance present in water which contaminates the ground water quality, so it may affect the ground water which drilled out through borewell or casing. A study has been carried out to get its physic -chemical characteristics of bore well and dug well water which are collected from Nagpur Region, Water samples were collected from different locations near from Nagpur region. The main aim of our study is assessing the water quality index (WQI) for ground water. At particular distance from Nagpur city .And analyzed for PH, conductivity, total hardness, Dissolved Oxygen, total alkalinity, sulphates, chlorides, temperature, TDS, physic - chemical Parameters and biological characteristics of ground water sample suggest that the monitoring of water quality below the ground surface as well as water quality management should be carried out periodic and as well as to protect the source of water resources. The study indicates the need for periodic monitoring and GIS based study of ground water in the study area which is high dense with population.

Chemical Analysis of Ground Water from Various Parts of Thanjavur District, Tamil Nadu (India)

The present study was to assess the quality of ground water from various parts of Thanjavur district, and check its fitness for drinking purpose. The pH was determined by pH metric method, calcium, magnesium, chloride were analyzed by titration method, sulphade, iron, nitrate, nitrite, chromium were estimated by spectrometric method ,total dissolved solids of the water samples were determined by gravimetrically, colour of the water samples were determined by platinum-cobalt method ,taste of the water samples were determined by taste rating method, turbidity of the water samples were determined by Nephelometric method etc., are determined for some parts of Thanjavur district water samples and compared with standard limits recommended by BIS. Comparative study of groundwater for this region can be used for the quality of water is suitable for drinking purpose, but the ground water sample numbers S2, S3, S4, S5, S6, S7 and S9 is not suitable for drinking purpose, because in the presence of excess of hardness (Ca2+, Mg2+), chloride, and TDS.

Preliminary studies on removal of nitrate and hardness from ground water using polystyrene beads

Ground water has emerged as the primary water deficiency reduction tool in most developing countries. Recently, the quality of ground water has deteriorated due to over-exploitation and contamination resulting from anthropogenic activities. A broad range of physical, inorganic and organic, bacteriological, and radioactive parameters are found in ground waters. The presence of nitrate and hardness-causing ions at elevated levels is of greatest concern currently, as they can have a serious impact on human health and water distribution systems. The conventional methods which are applied to reduce the concentration of these inorganic constituents are found to be inconsistent when the concentration is significantly high. The present study is an attempt to remove nitrate and hardness-causing ions using polystyrene (PS) beads as packed media. The ground water sample had a total hardness between 1,030–1,250 mg/L, which is greater than the permissible limit, and the nitrate concentration was less than 45 mg/L. PS beads packed media was found to respond significantly in reducing nitrate by 88% and total hardness by 38% at an optimum flow rate and particle size of 3 L/min and 4 mm diameter respectively. PS beads can be a promising media in reducing nitrate and total hardness.
