The groundwater quality research is one of the important and its pollution control was included insome research literatures. Ground water quality has spatial and temporal variation so classical statisticscould not account these variations at the regional scale researches. This study usedgeo-statisticalmethodsto optimize an interpolation method in order to estimate the spatial distribution of pH...
Water a vital component for all living forms is derived from variety of sources, including surface water (rivers, lakes, reservoirs and ponds) and ground water (aquifers). Over the years of time, water bodies are subjected to human interference regularly resulting in deterioration of water quality. Therefore, pollution of water bodies has become matter of global concern. As the water quality cl...
background: estrogens include estoril (e3), estradiol and estrone (e1). these chemicals are produced in human and animal bodies as well as in synthetic chemicals (drugs). estrogens can enter water sources in different ways. when these chemicals enter the human body through water and wastewater, they have the ability to mimic or disrupt the normal estrogen activities in humans and animals. estro...
Antibiotic-resistant fecal bacteria were used to monitor the degree of movement and subsequent ground water contamination by septictank effluent discharged into a drainfield under saturated conditions. Two pits of different depths were constructed to simulate drainfield beds, and ground water samples were removed uring 32-day sampling intervals from sampling wells installed at set distances fro...
The population of our country is increasing rapidly and due to it plastic waste is also increasing day to day due to urbanization, development activities and changes in life style, which leading extensive environment pollution. Thus disposal of waste plastic is a threat and become a serious problem globally due to their nonbiodegradability and anaesthetic view. Since these are not disposed scie...
The prevalence of various pollutants like nitrogenous, sulphurous, phosphorous compounds, heavy metals, and organic compounds has seriously threatened the sustainability of natural ecosystems and is thus interfering with the natural biogeochemical cycling. Chemical pollution of water bodies can cause serious damage to environmental quality because many of these pollutants are extremely toxic an...
Application of excess nutrients such as fertilizers is a significant and sometimes even major component of ground water pollution. Diffuse inputs of nutrients and contaminants to the ground water are related to runoff generated from precipitation in a catchment. Catchment’s response depends on site conditions and its physical properties. This implies that the analysis of diffuse fluxes from the...
objective: the world is currently facing with various problems including water and soil pollution as well as a major threat to the health of the citizens due to the advancement at human civilization, technology development, pesticides and chemical fertilizers application, the increasing exploitation of natural resources by the agricultural sector and the increasing usage of fossil energy. there...
