  • Hand-pumps as reservoirs for microbial contamination of well water

    The retention and release of total coliforms and Escherichia coli was investigated in hand-pumps removed from tubewells tapping a faecally contaminated aquifer in Matlab, Bangladesh, and from a new hand-pump deliberately spiked with E. coli. All hand-pumps were connected to reservoirs of sterile water and flushed. Faecal coliforms were observed in the discharge from all three of ...

    This article points out the magnitude of this urgent issue.  An abandoned well becomes an opening into an aquifer which is likely to introduce contamination.  Filling it in is a critical component of protecting the well water supply.  Click here to read the ...

  • Influences on the water testing behaviors of private well owners

    Many private wells in the United States and Canada already are contaminated, or are at risk of contamination. Regular testing for pathogenic bacteria is one of the most concrete measures well owners can use to determine whether or not their drinking water quality is safe. This study explored the factors and causal relationships that influence well owner water quality testing behavior. In-depth, ...

  • Tidal influences on unconfined water levels in wells.

    Tidal effects have the potential to measurably affect water level measurements and the estimation of groundwater flow direction and gradient. This has significant implications for the prediction and monitoring of contaminant plumes in coastal areas. Studies were conducted at two near-coastal sites in San Diego County, California, to evaluate the impact of tidal variability on the interpretation ...

  • Evaluation of a Horizontal Well

    Background: Air Sparging Air sparging is an in-situ remediation technology where air is injected into the saturated zone of an aquifer. It is an alternative to conventional ex-situ pump and treat systems for remediation of contaminated ground water. It is necessary to understand the pattern of air flow that will occur in the subsurface in order to determine the optimal placement, ...
