The industrial town of Faridabad lies in the northern part of India and is currently undergoing speedy urbanization with high industrial growth in NCR. This has, coupled with its speedy urbanization and industrial development, led to impacts on groundwater resources within it. However, it's essential for drinking, irrigation, and industrial purposes. The present study involves essential water quality parameters like pH, total dissolved solids, total hardness, chloride, nitrate, sulphate, sodium, potassium, calcium, and magnesium for assessing the suitability of groundwater for irrigation and consumption. From the above data and interpretation, it will be enough to make a general suitability assessment for different water uses. With this, it can be observed that the pH in water at most places fall in the optimum scale, which could be presumed to state that neither water is too acidic nor alkaline. On the other hand, high levels of TDS at all indicative points reveal that water may have problems related to taste and long-term health issues. In most of the cases also indicate that total hardness and chloride exceed the desirable limits, which can lead to corrosion in pipes and have a salty taste. The nitrates were within permissible limits, but the sulphates, sodium, and potassium were within high concentrations in some of the locations and, therefore, reflective of the salinity of the soil and ensured health. of crops. High levels of magnesium indicated probable ill effects on agricultural yield. It is thus essential to regularly monitor and treat groundwater for its sustainability. This further reinstates the need for effective practices and policies related to water management, which must prevent or at least minimize the adversities posed by groundwater contamination, hence saving people's health and well-being and the sustainability of agricultural practices in Faridabad. 2024-05-01T00:00:00Z http://dspace.dtu.ac.in:8080/jspui/handle/repository/20898 Title: ESTIMATION OF VEHICULAR EMISSION LOAD ALONG A SELECTED ROAD CORRIDOR IN DELHI Authors: SEPAVAT, SANJEEV SINGH Abstract: Globally, vehicular emissions are recognized as the main source of air pollution in urban areas. The trend of urbanization has led to a surge in private vehicle ownership, particularly in metropolitan cities such as Delhi, India, resulting in significant growth of the automobile sector. Additionally, Delhi has experienced a considerable influx of people migrating from neighboring states in the past decade, leading to higher demand for transportation facilities. The growing number of vehicles has a direct impact on air pollution by causing higher fuel consumption and increased traffic congestion. The activity of vehicles on congested roads, including sudden acceleration and deceleration, significantly affects emissions. As a result, precise estimation of vehicular emissions is critical in developing systematic pollution mitigation strategies. This study focuses on the estimation of vehicular emission loads along a selected road corridor in Delhi, aiming to evaluate the effectiveness of various mitigation policies. Utilizing the CPCB VKT method, the emissions of key pollutants including Carbon Monoxide (CO), Hydrocarbons (HC), Particulate Matter (PM), Nitrogen Oxides (NOx), and Carbon Dioxide (CO2) were measured. Multiple scenarios were developed to analyze the impact of different policies, and these were compared with the Business-As-Usual (BAU) scenario to determine their effectiveness. The results provide valuable insights into the potential benefits of implementing specific strategies to reduce vehicular emissions and improve air quality in urban settings. Scenario 1,2 and 3 reduces the vehicular pollution significantly. So, we can say that adopting electric vehicle will help to curb vehicular pollution more efficiently. 2024-05-01T00:00:00Z http://dspace.dtu.ac.in:8080/jspui/handle/repository/20897 Title: SPATIAL-TEMPORAL ANALYSIS OF STUBBLE BURNING IN PUNJAB USING ArcGIS AND ITS IMPACT ON GREEN HOUSE GAS AND PARTICULATES EMISSIONS Authors: YADAV, NISHANT Abstract: Burning crop residue is a significant worldwide environmental issue and one of the main contributors to the atmosphere's pollution and greenhouse gas emissions. Burning agricultural crop residue increases the emission of smoke, particulates matter, CO2, N2O, CH4, CO, NH3, NOx, SO2, NMHC, and volatile organic compounds, all of which are harmful to human health. Crop residue is produced in large amounts, with 71% of the net sown area planted in paddy during the kharif season and 84.6% under wheat during the rabi season. Of this, each year, 25% of the wheat straw and 95% of the paddy straw are burned. The dangerous practice has had a negative impact on soil, air, road safety, health, and other areas, resulting in significant financial and physical losses. This study calculated the greenhouse gas emissions related with analysing active stubble burning data data from the Moderate Resolution Imaging Spectroradiometer (MODIS) during a 5-year period (2019–2023). Using the MODIS-Terra+Aqua Direct Broadcast Burned Area Monthly L3 Global 500 SIN Grid V061) product, Arc GIS Pro 10.3 and the Punjab government GIS portal for crop burning data, fire hotspots were identified, indicating that the burning of crop residue in Punjab's agricultural fields may be the cause of the elevated pollutant levels. Analysis of active fire locations found in the MODIS and PRSC Crop Residue Burning (CRB) Information and Management System over a five-year period between the kharif and rabi seasons indicates that stubble burning is still being done. In Punjab, there were 358965 burning events total between 2019 and 2023, distributed as follows: 73684, 90943, 82178, 64135 and 48026. Monitoring conducted at the district level in Punjab's southwest and eastern regions during the research period revealed a notable increase in the number of fire incidents. For rice crops, the anticipated total greenhouse gas and particulates emissions between 2019 and 2023 varied from 19868 Gg/year to 21,921 Gg/year and for wheat crops, from 7961 Gg/year to 9852 Gg/year. The main causes of the practice's persistence were found to be a scarcity of buyers, a lack of time for the next harvest, a lack of support from the state government, and a workforce shortage. Farmers were advised to take steps to address the issue, such as using it as animal feed, providing subsidies for machines like the "Happy Seeder," which produce less straw during harvesting etc. 2024-08-01T00:00:00Z http://dspace.dtu.ac.in:8080/jspui/handle/repository/20866 Title: HEAT WAVE ASSOCIATED WITH SURFACE OZONE POLLUTION IN DELHI Authors: CHAUDHRY, MOHAMMAD ARSH HANIF Abstract: Heat waves are expected to grow more extreme across most worldwide land regions as greenhouse gas levels continue to rise and average temperatures rise in both trials (greater maximum temperatures during heat waves). It was hypothesized that heat waves are associated with surface ozone levels. To test this hypothesis correlation and regression analysis were used across Delhi using the air quality data from 4 monitoring stations run by CPCB. The ozone concentrations have been studied for monthly and seasonal patterns. Dependence of surface ozone concentration on PM2.5, PM10, NO, NOx, CO, SO2, Relative Humidity, Ambient Temperature, and Wind Speed has been studied. The role of ozone precursors and reduction in PM2.5 and NOx have been illustrated. Significant association was found among temperature and ozone further it was observed that Ozone concentrations fluctuate throughout the day, for different study period. Additionally, the role of NOx, VOCs and solar radiations in ozone formation have been discussed. 2022-05-01T00:00:00Z
