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 the previously ...

Optimal groundwater contamination monitoring using pumping wells
This study presents a new method for selecting monitoring wells for optimal evaluation of groundwater quality. The basic approach of this work is motivated by difficulties in interpolating groundwater quality from information collected for only few sampled wells. The well selection relies on other existing data relevant to contaminant distribution in the sampling domain, e.g. predictions of ...

Effective Groundwater Monitoring Using Dedicated Pumping Tubes
This article describes a groundwater monitoring procedure that does not require decontamination of pumping equipment, eliminates the chance of cross contamination between wells, and uses a surface pump. Two surface pumps are described, one for water level depths less than 25 feet and one for water level depths greater than 25 feet. Install Dedicated Pumping Tubes A dedicated pumping tube ...

Groundwater Monitoring with the Waterra Inertial Pump
Untitled Document Abstract The Waterra Inertial Pump has been available for use in narrow diameter monitoring wells for several years. This device offers many advantages over other types of sampling equipment. Since this pump operates via a principle not used by any other type of device and is commonly constructed of materials not widely used in field sampling, some ...

Pump/Recharge Rate Affects Saltwater Intrusion
Untitled Document Many areas of the world use groundwater as their main source of fresh water supply. With the worlds population increasing at alarming rates, the fresh water supply is being continually depleted, increasing the importance of groundwater monitoring. One of the major concerns most commonly found in coastal aquifers, is the induced flow of salt water into fresh ...

Multilevel Groundwater Assessment of Confining Unit in a Bedrock Sequence near Sarnia, Ontario
Untitled Document INTRODUCTION Two sites in southern Ontario were studied through instrumentation of boreholes with Waterloo Multilevel Monitoring Systems. These sites are located approximately 7 km (4.3 miles) apart and lie between Sarnia to the northwest, and Petrolia to the east in lambton County, Ontario, Canada (figure 1). Multilevel monitoring devices were installed to ...
