Groundwater samples were taken from piezometers installed at seven metres depth and results showed 99% elimination of contaminant in groundwater with TPH concentration of 15 mg/l. ...
Instrumentation of Cone Penetration Tests (CPT's), standpipe and vibrating wire piezometers were installed at the project. This paper focuses on the role of the PVD's as drainage elements for the quick bursts in pore pressure and the results are presented herewith. ...
The chambers were designed to reconnect up to 160 ML/year of runoff, the equivalent of 64Olympic swimming pools, from impermeable surfaces on the campus to natural underground storage in theBotany sand aquifer.As well as replenishing the aquifer, which is used as an additional water supply by local residents and industry, the pit takes some pressure off Kensington’s storm water pipes by ...
The shafts for an outfall tunnel in New York required shoring for excavation support and groundwater control. Since there was limited room at site, ground freezing was selected to provide the shoring, instead of a diaphragm wall. Ground temperature monitoring was a critical component, to allow for modeling of the freeze bulbs and to verify when it was safe to begin excavation of the shaft. ...
This behavior was monitored closely and a program for reading the installed piezometers was established. During the readings, a high-pressure anomaly was found in the clay core suggesting the formation of a fissure or other defect. ...
This project involved simulating mine dewatering and excavation to evaluate future dewatering requirements, as well as providing guidance for future monitoring borehole and piezometer designs. Office U.S. Denver Itasca Denver, Inc. ...
THE CHALLENGE An earthfill dam, in Austria, had a planned underseepage, with several piezometers installed to understand the water flowing beneath the dam. The owner wanted to know if there were preferential seepage paths or if the seepage was evenly distributed in the foundation. ...
These sensors included vibrating wire piezometers, joint meters, fill extensometers and strain gauges. Each sensor needed to interface with a universal data logger as part of a long-term logging solution. ...
CUSTOMER: SICE USER: Ebro Hydrographic Confederation (Spain) LOCATION: Ebro river basin ENVIRONMENT: Countryside YEAR: 2017 The system integrator SICE engineering, which installs and maintains the Automatic Hydrological Information System (SAIH) of the Ebro Hydrographic Confederation with more than 900 RTU (Remote Terminal Units) and a remote control SCADA, needed to monitor continuously ...
This determination was based on PCE concentrations in adjacent monitoring wells, streambed piezometers, and surface water samples combined with the site specific soil and groundwater hydraulic data. ...
The soil borings were converted to temporary piezometers to obtain groundwater samples and to evaluate the connection of the overburden with the bedrock during the bedrock injections. Benzene was detected as high as 9,890 μg/l. The piezometers confirmed that the overburden was contributing to the impacts identified in the bedrock monitoring wells. ...
Chemical and isotopic analyses of groundwater from piezometers localized around a reclaimed landfill were performed in order to identify the boundaries of groundwater contamination zone. Spatial distribution of dissolved inorganic carbon (DIC) concentration and stable carbon isotopes in the groundwater was used to distinguish the piezometers localized within the ...
Four OWS including two conventional and two single-pass sand filter (SF) systems were evaluated at sites with clay-rich soils. Piezometers were installed near all of the OWS, and down-gradient from the conventional OWS for groundwater collection and characterization. ...
As part of that investigation, they measured the water temperature versus depth at 56 piezometers. EnviroInsite was then utilized to establish the relationship of water temperature with land use, surface water temperature, and proximity to the ...
The long-term fluctuations of the water table in 13 piezometers were simulated by a wavelet-based artificial neural network (WANN) hybrid model, and their statistical gaps were covered. ...
Twelve of these wells were water-table wells and 11 were piezometers. Of the 23 wells, 14 had significant temporal trends (increasing or decreasing) for NO3−-N and/or Cl− concentrations. ...
The goal of this study was to determine if onsite wastewater treatment systems (OWS) were influencing groundwater and surface water Escherichia coli concentrations in a coastal plain watershed. Piezometers for groundwater monitoring were installed at four residences served by OWS and five residences served by a municipal wastewater treatment system (MWS). ...
CAP called for drilling 12 soil borings and installation of 18 piezometers and 6 sets of nested (3 per) ground water monitoring wells. ...
Best fits between the simulated and measured piezometric heads were obtained at leakage factors B ranging between B >= 150 m and B Keywords: leaky aquifer, leakage factor, groundwater model, hydro-geology, ...
The instruments were put in direct wells (piezometers, ready for immediate use) that were driven into the peaty soil using a slide hammer. ...
