Arsenic Contamination in Groundwater: a Statistical Modeling

High arsenic in natural groundwater in most of the tubewells of the PurbasthaliBlock II area of Burdwan district (W.B, India) has recently been focused as a serious environmental concern. This paper is intending to illustrate the statistical modeling of the arsenic contaminated groundwater to identify the interrelation of that arsenic contain with other participating groundwater parameters so t...

Groundwater Contamination

INTRODUCTION In the southern United States, chemicals are an integral part of the management of bare-root nurseries. The rationale for using chemicals is based on economics as they can reduce hand labor, improve the use of valuable seed, and increase seedling performance. The cost of all chemicals associated with loblolly pine seedling production averages less than 0.2 cent per seedling. The co...

Statistical modeling of global geogenic arsenic contamination in groundwater.

Contamination of groundwaters with geogenic arsenic poses a major health risk to millions of people. Although the main geochemical mechanisms of arsenic mobilization are well understood, the worldwide scale of affected regions is still unknown. In this study we used a large database of measured arsenic concentration in groundwaters (around 20,000 data points) from around the world as well as di...

Groundwater Contamination from Agro-Chemicals in irrigated Environment: Field Trials

This paper highlights on the increasing fears that chemicals in agriculture have found their way into drinking water causing health complications. In fact many chemicals have not had these effects but waiting to do so by moving into groundwater sinking slowly and finally going into taps. Nitrate fertilizer is largely blamed for these fears. Use of fertilizers obviously would increase manifold t...

Modeling groundwater velocity uncertainty in nonstationary composite porous media

R R E C T E Summary Despite the intensive research over the past decades in the field of stochastic subsurface hydrology, our ability to analyze and model heterogeneous groundwater systems remains limited. Most existing theories are either too restrictive to handle practical complexity or too expensive to be applied to realistic problem sizes. In this paper we present approximate, closed-form e...
