Remediation: Streamside Solution

Characterization of a Polyacrylamide Solution Used for Remediation of Petroleum Contaminated Soils

Biopolymers are viewed as effective and eco-friendly agents in soil modification. This study focuses on the wettability analysis of polyacrylamide (PAM) solutions for soil remediation. The contact angle, surface tension, and viscosity of PAM solutions were experimentally evaluated in air- and decane-biopolymer solution systems. Furthermore, a micromodel was used to investigate the pore-scale di...

Remediation of 4-nonylphenol in aqueous solution by using free radicals generated by the oxidative reactions

INTRODUCTION This study relates to use of zerovalent iron to generate hydroxyl free radicals and undergo subsequent oxidation to destroy 4-nonylphenol (NP) by mild process in aqueous solution and activation of oxygen gas (O2) at room temperature. This technology is based on a novel oxidative mechanism mediated by zerovalent iron rather than commonly used reduction mechanism. MATERIALS AND MET...

Remediation and Respect: Do Remediation Technologies Alter Our Responsibility?

In this paper we examine the relation between technologies that aim to remediate pollution and moral responsibility. Contrary to the common view that successful remediation technologies will permit the wheels of industry to turn without interruption, we argue that such technologies do not exculpate polluters of responsibility. To make this case, we examine several environmental and non-environm...

Remediation in Constructed Wetlands

Constructed wetlands are in use to improve the quality of contaminated groundwaters at many sites in the USA. Target contaminants include both organic and inorganic constituents. Volatile and nonvolatile hydrocarbons are found in ground water at closed petroleum refinery sites, and in leachates from landfills. Polycyclic aromatic hydrocarbons are pollutants at many sites. Chlorinated organics o...
