  • Sampling and On-Site Analytical Methods for Volatiles in Soil and Groundwater - Field Guidance Manual

    Abstract: Volatile organic compounds (VOCs) are among the most frequently identified contaminants in soil and groundwater samples obtained during the investigation of suspected hazardous waste sites. Because some VOCs and their degradation products are potentially mutagenic, carcinogenic, or teratogenic, their concentrations in these two matrices are key factors in the risk assessment process. ...

  • Evaluating groundwater/surfacewater transition zones in ecological risk assessments

    Currently, there is a common perception that the discharge of contaminated groundwater to a surfacewater body does not pose an ecological risk if contaminant concentrations in surface-water samples are below analytical detection limits or at very low concentrations. The transition zone represents a unique and important ecosystem that exists between surface-water and the underlying ground-water, ...

  • Breakthrough studies with mono-, binary- and ternary-ion systems comprised of Fe(II), F and As(III) using river sand packed columns for groundwater treatment

    Groundwater in Assam, India, contains excessive amounts of arsenic (As(III)), fluoride (F−) and iron (Fe(II)). The rural and semi-urban population of Assam uses indigenous iron filters fabricated using processed sand (PS) as one of the chief constituents to reduce Fe(II) concentration; however, no efforts have been made to reduce As(III) or F− concentrations before use. ...

  • Novel carotenoid-based biosensor for simple visual detection of arsenite: characterization and preliminary evaluation for environmental application

    A novel whole-cell arsenite biosensor was developed using the photosynthetic bacterium Rhodopseudomonas palustris no. 7 and characterized. A sensor plasmid containing the operator-promoter region of the ars operon and arsR gene from Escherichia coli and the crtI gene from R. palustris no. 7 was introduced into a blue-green mutant with crtI deleted, R. palustris no. 711. The biosensor changed ...
