Textile industry processes are among the most environmentally unfriendly industrial process, because they produce colored wastewaters that are heavily polluted the environment. Therefore, wastewater from textile industry has to be treated before being discharged into the environment. In this present study, an attempt has been made to evaluate the effectiveness of locally available natural coagulant Neem leaves powder for reduction of characteristics in the wastewater in order to improve its quality. A common herb like Neem leaves powder is utilized to illuminate and sterilize the water. The coagulant chemicals play the vital role in wastewater treatment. At the same time spending more amounts for these chemical coagulants increase the total treatment cost and become more burdens to the industry. In view of the replacement or reduction of chemical coagulants which are used in wastewater clarification, coagulants which are effective, productive and also free from physio-chemical characteristics are considered. Using natural coagulants is more eco-friendly and sustainable when compared to the chemical coagulants which is biodegradable.

In this study, an overview of hydro geological processes and concepts regarding groundwater flow and contaminant in most parts of many countries .Groundwater pollution is imminent in most developing countries as a result of increased anthropogenic activities apart from possible natural pollutants. The world’s population is facing a water crisis, which is expected to worsen dramatically during the 21st century. Problems due to over exploitation of groundwater, as well as from natural and anthropogenic contamination are major challenges facing humanity. This study reviewed groundwater pollution and discussed possible remediation measures. It is recommended to carry out a continuous water quality monitoring program and development of effective management practices for utilization of water resources.

Water is indispensable for all the life forms on earth. But the comprehensive quality of water such as free from chemical pollutants and microbial contaminants is vital. The present circumstance of industrialization and urbanization has taken a toll on environment, polluting the soil, air, and water. Pollution as well as global warming has exhibited detrimental effects on our natural resources of which water becomes the inexplicable. Failing monsoon rains due to climatic changes, population explosion, and depletion of natural water resources such as groundwater, ponds, and lakes as well as intentional man-made pollution of rivers has lead to water scarcity. Even the scarcely available water is loaded by contaminants and pollutants which include mutagens, carcinogens, and pathogenic microbes affecting all the life forms affecting the ecological balance. Considering the above mentioned problem criteria, a part of the present work has been designed to analyze the quality of ground water around the industrial premises. For this objective, we have collected ground water samples from various locations in and around Perundurai area in Erode District focusing on quite far away from Industrial premises considering the concepts of leaching. Basic physio-chemical properties of the collected ground water samples have been analyzed by APHA standards. Comparative data analysis for the samples based on the analyzed parameters has been made. Highest possibility of water quality issues which affects the day to day consumption of ground water for the domestic needs of the people has been emphasized.
