Barrier-controlled monitored natural attenuation.
Three existing technologies (source containment, source reduction, and monitored natural attenuation) are integrated in barrier-controlled monitored natural attenuation (BCMNA)--a new approach for managing plumes of contaminated groundwater and remediating contaminated sites. The basic BCMNA concept uses a low-permeability, nonreactive barrier to release contaminants into an aquifer at a rate t...
متن کاملMicrobial Processes Affecting Monitored Natural Attenuation of Contaminants in the Subsurface
It should be emphasized that this document is not intended to be used in establishing protocol involved in natural attenuation investigations or policies leading to the interpretation of the results of those investigations. To that end, the reader is referred to the EPA Protocol for chlorinated solvents (U.S. EPA, 1998a), and ASTM for petroleum hydrocarbons (ASTM, 1998). EPA is also preparing a...
متن کاملNatural attenuation of arsenic by sediment sorption and oxidation.
Arsenic sorption onto aquifer sediments was investigated in anaerobic laboratory batch and column uptake experiments and characterized by As, Fe, and Mn X-ray absorption spectroscopy (XAS) to estimate the extent and mechanism of abiotic sorption and oxidation of As(III). Batch experiments at pH 6 showed that the amount of As(III) or As(V) sorption from synthetic background porewaterto sediments...
متن کاملNatural Bio-Remediation of Arsenic Contamination: A Short Review
The problem of water pollution is now a problem of commons, round the globe [1], but the problem of arsenic contamination in the groundwater is not too old. Arsenic (As) is a metalloid and it belongs to Nitrogen Group [Va] of the periodic table. The atomic number of Arsenic is 33 and atomic mass is 74.922. Arsenic is found as one stable isotope, 75As which is non-radioactive. Arsenic appears in...
