Inefficient remediation of ground-water pollution

optimal identification of ground-water pollution sources

a new mathematical model for identifying pollution sources in aquifers is presented. the model utilizes lagrange constrained optimization method (lcom) and is capable to inversely solve unsteady fluid flow in saturated, heterogeneous, anisotropic confined and/or unconfined aquifers. throughout the presented model, complete advection-dispersion equation, including the adsorption as well as retar...

Ground Water Issue: Steam Injection for Soil and Aquifer Remediation

Innovative technologies for subsurface remediation, including in situ techniques based on heating the subsurface to enhance the recovery of organic contaminants, are increasingly being evaluated for use at specific sites as the limitations to the conventionally-used techniques are recognized. The purpose of this Issue Paper is to provide to those involved in assessing remediation technologies f...

The Risk of Pollution of Ground Water from Borehole Latrines

Remediation of ozone pollution by ornamental plants in indoor environment

The indoor air quality is much more matter of concern as relative to ambient or outdoor air quality, especially in the context of human health.  However, very few studies have been reported for remediation of indoor ozone by plant species. The main objective of this study is to evaluate ozone deposition velocities and ozone removal effectiveness of three indoor ornamental plant species (Dra...

The role of soil layers in preventing ground water pollution with 17ß-estradiol hormone (E2)

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...
