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. ...
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. ...
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. ...
To monitor performance, groundwater samples were collected from the pilot test well network and the nested streambed piezometers pairs (installed 2 ft and 4 ft below the streambed). Pilot test monitoring was performed for two years and a full scale BOS 100® PRB was installed in the fall of 2015. ...
The goal of this study was to gain a better understanding of the PO4-P treatment efficiency of onsite wastewater systems (OWS) installed in nutrient-sensitive watersheds of the North Carolina Piedmont. Four OWS including two conventional and two single-pass sand filter (SF) systems were evaluated at sites with clay-rich soils. Piezometers were ...
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. ...
The goal of this study was to determine the treatment efficiency of four OWS in reducing total dissolved nitrogen (TDN) and dissolved organic carbon (DOC) concentrations before discharge to groundwater and/or adjacent surface water. Piezometers were installed for groundwater sample collection and nutrient analysis at four separate residences that use OWS. ...
Result: The sheen dissipated from the fresh water bay as soon as the RCM and PRB was installed and brought online. The installed cost for mobilization/demobilization, RCM installation, PRB installation, site restoration, and waste disposal was approximately $220,000. The organoclay RCM and PRB have worked successfully for three ...

Portable air purifying units were installed in the buildings to reduce indoor air concentrations to acceptable levels as an interim response action. ...
Evaluation A limited site assessment was performed to determine the vertical profile of impacted soils and groundwater, and quantify the amount of petroleum hydrocarbons present. Three piezometers were installed within 20 to 50 feet of MW-10 to determine the radius of influence of the injection and to understand the hydraulic effects that result when an ...
These data were used to locate topographic lows on the clay surface for installation of new piezometers. The piezometers were intended to monitor perched zone dewatering and aid in the conceptual design of possible remedial measures. ...
At a field site along the Barren Fork Creek in northeastern Oklahoma, a trench was installed with the bottom at the topsoil/alluvial gravel interface. Fifteen piezometers were installed surrounding the trench to monitor flow and transport. ...
Prior to advancements in multilevel instrument design this detailed monitoring was accomplished either by drilling numerous separate boreholes to various depths, often referred to as a cluster type installation, or by installing a series of piezometers at different depths in a single borehole, nested type (Figure 2). ...
