One study performed in Sreenagar, Bangladesh, showed that awareness of the arsenic severity might not affect people’s behavior as much as may be expected (Inauen, 2013). The psychological study concluded that social factors, such as having full knowledge of contamination levels and risks, were the most significant influence in determining what water source people used (Inauen, 2013). b. Show data that supports the reduction in cases of arscenosis for people who have switched to green tubewells

Seawater intrusion is defined as the movement of seawater into freshwater aquifers which are generally made of ground water near the coast. An interface or dispersion zone is the area where fresh water and seawater meet. Analytical models and numerical models as well as Mathematical methods are used to find or to investigate solutions to this, as the seawater contaminates the fresh drinking water. The aim of this essay is to give an account of two modelling approaches that describe what happens at

northeastward to 320 kyr in Farafra and 700 kyr in Bahariya (Fig. 5). 36Cl/Cl ratios vertically indicate long, deep flowpaths of the paleorecharge near the southern highlands of the Uweinat area. Late Quaternary recharge appears to affect the shallow aquifer horizons only (Paterson et al., 2005). Krepton-81 ages (Sturchio et al., 2004) show also a progressive increase with distance to the east and north from the Dakhla Oasis, their spatial distribution indicates relatively high flow velocities (~1 m/yr–3

The Golden State of Mind is Dried And Cracked It’s hard to imagine what life would be like without easily accessible and plentiful water. Humans use water in many different ways for a number of important reasons, so the current drought that’s taking place in California is a big deal. Last year, during an outdoor speech, California governor Jerry Brown made this statement: "Today we are standing on dry grass where there should be five feet of snow. This historic drought demands unprecedented action

Groundwater pollution is a prominent problem in most areas of the world. High nitrate concentrations have been identified as one of the main culprits of groundwater pollution. Agriculture is a primary anthropogenic source involved in the spreading and distribution of nitrates in rural areas. China is considered one of the largest in terms of agricultural production. As the population of China increased over time, the recycling of plant nutrients could no longer renew the loss of nutrients from harvesting

4.3. Subsurface water considerations to research: 4.3.1. Rock Fracture Density and Permeability Estimates Fracture density can be defined as the number of fractures per unit length, area or volume. Fracture density is largely dependent on local bedding thickness and location relative to local faults. Due to the mountainous nature of the Andes Mountains and the close proximity of Ocelot Mine to the MFTB, the limestone host rock can be considered to have a heavy fracture density. Fractures also

An Issue for California’s Water Supply Now and in the Future: Educating Urban Consumer’s to Reduce Consumptive Usage Michael McCullough California Polytechnic State University San Luis Obispo Introduction Water is essential to sustain life. It is becoming an ever more valuable resource every year as it becomes scarcer. The general problem is that California is in the midst of a severe drought. The specific problem is that the typical urban consumer has little knowledge of how to reduce their

The use of pesticides have been dated back to over 4,500 years ago, when the Sumerians used sulphur compounds to protect crops from mites and insects (1). The use of pesticides are abundant in the United States and globally. The United States accounted for over one billion pounds of pesticide use in both 2000 and 2001, with over five billions pounds used worldwide in each year (2). The United States accounted for approximately 23% of the global use of pesticides. Pesticides have long been used

1. Abstract Energy, water, and food are interdependent on one another. Water is the main contributor for the production of agriculture along with other food substances. The distribution of water is reliant on energy. Energy is used to pump water from the ground. Water is used in agricultural irrigation and energy is used to harvest the crops for food. All three sectors are indicators of a strong society. The relationships between these three sectors come with a cost. High amounts of energy are used

Indirect reuse is discharge of an effluent to impoundment, receiving water or groundwater aquifer for assimilation and withdrawal from downstream. On the international scale, direct non-potable water reuse is currently the dominant mode for supplementing public water supplies for irrigation and other applications, which includes all reuse applications that do not involve either indirect or direct potable use. On the other hand, indirect potable waste water reuse, through waste water effluent disposal
