Client: Trent Conservation Coalition Drinking Water Source Protection – Lower Trent Conservation: Ms. Andrea Hicks, 714 Murray Street, R.R. #1, Trenton, ON K8V 5P4 Key Personnel: E.J. Wexler Earthfx Incorporated delineated wellhead protection areas (WHPA) for all municipal wells within the Trent Conservation Coalition Drinking Water Source Protection Region. Included in this ...

THE GRIFFIN DIFFERENCE The construction sequence on this project was dependent on the efficient and proper installation of the wells by the Griffin team. To confirm our design and aquifer assumptions, we performed a pumping test at the beginning of the project. ...
Matt Reeves says is the only opportunity most students will get to practice monitoring and testing techniques, work with top-quality equipment, and prepare professional-quality reports. Reeves co-directs the course and teaches one-week modules on aquifer testing and remediation. For the Aquifer Testing module, ...
As the results of groundwater flooding are likely to be less apparent after rainfall, and more difficult to prevent than surface level flooding, it is important to monitor groundwater levels regularly. Identifying aquifers Aquifers are underground layers of water-bearing permeable rock, or materials such as gravel or sand. ...
City West Water (CWW) has developed an Integrated Water Cycle Management (IWCM) Strategy which includes the development of aquifer storage and recovery (ASR) schemes to store recycled water and storm water to assist with meeting future growth, where these schemes can be demonstrated to be viable and cost effective. ...
The slug test is still one of the simplest and cost-effective methods to interpret the hydraulic parameters for aquifer analysis. This study introduces two new estimation approaches for the slug test, the time shift method (TSM) and arc-length matching method (AMM), to identify aquifer parameters in a reliable and accurate ...
Both of these sensors collect data in linear, linear average, or event logging modes, and are mostly used for long-term monitoring or slow-responding slug tests. The Level TROLL 700 is the Cadillac of the Level TROLL line. ...
-The University of Alberta is partnering with industry and government to test and develop scalable, commercial-grade solutions for deployment. ...
Defining aquifer permeability distribution accurately over large areas is often debated in hydrogeology. The operational efforts to calculate hydraulic conductivity with classical aquifer tests are significant; however, accurate knowledge of permeability areal distribution is fundamental both from a hydrogeological and a modeling standpoint. ...
The accompanying hydrographs represent the data collected for a Test Well located near Lake Simcoe (north of Toronto) in 2010. It was difficult to coordinate the schedule of the water well contractor due to inclement weather (bitterly cold) and the project site was approximately two hours from Geo Kamp’s office. ...
Groundwater in the Las Flores basin is extracted from the alluvial aquifer and the San Mateo aquifer located in the coastal basin. The San Mateo aquifer is overlain by unconsolidated alluvial deposits and underlain by the San Onofre Breccia. ...
Early-time transient electromagnetic sounding (TEM) and DC resistivity sounding techniques have been used to monitor remotely the changes with time of a groundwater pollution plume at a test site on a sand aquifer. A range of techniques for interpretation of TEM sounding data have been evaluated. ...
The hydraulic properties of the aquifer were tested, and soil, surface water and groundwater samples were collected at various times in the year. ...
Some states require 60-day aquifer yield tests, and plants must continue to monitor impacts to groundwater resources during the life of plant operation. ...
Shallow aquifers can cross-contaminate deeper aquifers through penetration of an intervening aquitard, via sandy intervals in the aquitard, along well casings, across long well screens, or around aquitard pinchouts. ...
Transmissivity estimates derived from non-steady-state, single well, constant discharge, aquifer tests in laterally heterogeneous environments generally are questioned relative to their representativeness of aquifer conditions. ...
This pilot study was the first to evaluate this technology in a high-flow karstic limestone aquifer. Extensive geophysical logging, packer testing, and discrete sampling were conducted to evaluate the fracturing and hydraulic properties of the bedrock for the injection design. Extensive on-site and downgradient monitoring was conducted during the pilot study to ...
A double-packer system was used to characterise the aquifer hydraulic properties (transmissivity, storativity, hydraulic gradient), with a test-zone (inter-packer) spacing of 1 m for tests in the plume and 2 m below the inferred base of the plume. Prior to hydraulic testing the boreholes were developed using a submersible pump ...
