The work was done in support of the Hydrogeological/Geotechnical Southeast Collector Trunk Sewer Environmental Assessment. ...
Consequentially, information may be scattered with significant gaps in data coverage which requires interpolating between data points and the introduction of risk to decision making. ...
Groundwater Solutions advised the voluntary group that a hydrological assessment of the pools would be required to inform the proposed design of the modifications to the pool system. A review of all existing data and information relating to the site was undertaken and a hydrogeological conceptual model was produced. The development of the site’s ...
Tianjin Municipality was selected because of its complicated hydrogeological conditions and rich data, which could be used to test a refined groundwater flow model for the shallow aquifer. ...
Consequently, many governments have acquired groundwater information in the aim of protecting the resource. Nevertheless, the resulting data are often ill-fitted to planning needs. In a previous study, a method was developed to help planners interpret hydrogeological data. It combines land planning and hydrogeological ...
The major objectives of monitoring should include the evolution of disposal systems compared to the baseline data of the undisturbed site, as well as the validation of the assumptions and results of the safety assessment. Hence, monitoring is performed in support of safety assessment activities concerning geological, hydrogeological, geo–mechanical, and ...
To understand the origin, occurrence and dynamics of the saline groundwater, a coupled analysis of major ion hydrochemistry and environmental isotopes (δ18O, δ2H and 3H) data supported by conventional hydrogeological information has been undertaken. These spatial and multi-temporal hydrochemical and environmental isotope data ...
There are a number of considerations when installing an ATES system, including site-specific hydrogeology, aquifer characteristics, the number and depth of boreholes and space between, optimum flow rates, the thermal loads of the buildings and field pipework routes from the boreholes to the mechanical plant room. ...
1.0 Introduction Willowstick Technology (the “Technology”) delineates and characterizes subsurface aqueous systems in complex hydrogeologic settings. It has consistently proven valuable in: 1) the diagnosis of seepage through earthen dams and levees; 2) characterizing groundwater infiltration into surface and subsurface mines; 3) tracking pollution plumes influenced ...
Generalised linear models and joint generalised linear models are appropriate for analysing positive data with constant and non–constant variance, respectively. This article focuses on the use of these two techniques in hydrogeology. ...
We choose to operate at 380 Hz signal to maximize the coil magnetometer sensitivity, while neglecting ground induction in data processing and interpretation. "e electric current injection electrodes are placed in direct contact with groundwater to preferentially introduce electric current to follow the water of interest. "e measured components of the magnetic %eld, after removing ...
Geo Kamp Limited is pleased to present a typical hydrogeologic project using Heron Water Level Data Loggers (referred to as the dipperLog). The accompanying hydrographs represent the data collected for a Test Well located near Lake Simcoe (north of Toronto) in 2010. ...
From 1993 through 1999, Burns & McDonnell also collected extensive hydrogeologic data in the city’s well field through administration of subcontracts with several well drillers and local consultant MKEC, completing approximately 100 test bores used for geologic profiles, water level monitoring, pump tests and water quality data collection. ...
DNAPL characterization methods are grouped into approaches, which include site preparation, characterization, and data-processing activities necessary to design an effective remediation system. We compare the different approaches based on the level of chemical and hydrogeologic resolution, and the need for additional data requirements. ...
During remedial investigations, a significant amount of data of varying quality and formats is collected and compiled in a multitude of database structures. ...
Although many potential suppliers perform the modeling, sampling, and sample analysis required for monitoring natural attenuation, the evaluation of natural attenuation is often not straightforward and will require expertise in several technical areas including microbiology/bioremediation, hydrogeology, and geochemistry. When available, information to be obtained during ...
Conservative metals may only be temporarily immobilized with remobilization when natural attenuation reestablishes oxygenated soil conditions. Data Needs Although many potential suppliers perform the modeling, sampling, and sample analysis required for monitoring natural attenuation, the evaluation of natural attenuation is often not straightforward and will require expertise in ...
Detailed information on groundwater flow velocity, direction, and horizontal and vertical variability are essential baseline data requirements. Detailed soil and geologic data are required prior to and during the installation of sampling points. ...
