Containment for Ground Water, Surface Water, And Leachate
Containment measures are often performed to prevent, or significantly reduce, the migration of contaminants in soils or ground water. Containment is necessary whenever contaminated materials are to be buried or left in place at a site. In general, containment is performed when extensive subsurface contamination at a site precludes excavation and removal of wastes because of potential hazards ...

3 Reasons the Series PT-510 Excels in Well Water Measurement
In February we introduced our newest submersible pressure transducer, the Series PT-510. The Series PT-510 is an OEM-ready submersible transducer, with a maximum depth of 46 feet. Today, let’s look at three specific advantages of using the PT-510 in well water measurement. The size of the PT-510 is its first advantage in well water measurement. At less than an inch (0.9” / 21.9 mm) ...

Evaluation of the snap sampler for sampling ground water monitoring wells for VOCs and explosives
A series of laboratory and field studies were conducted to determine the ability of the Snap Sampler to recover representative concentrations of VOC and explosives in ground water. For the laboratory studies, statistical analyses of the data (for each analyte) were conducted to determine if the concentrations of analytes in samples taken with the Snap Sampler were significantly different from ...

LNAPL At Petroleum Product Terminal - Case Study
ABSTRACT BOS 200® was injected at a refined petroleum product terminal to remediate LNAPL in groundwater. Within one year after treatment, the site received a No Further Action status. CHALLENGES The remedial goal was to eliminate the reoccurrence of light non-aqueous phase liquid (LNAPL) which persisted with no apparent pattern. Annual fluctuations in groundwater elevation were ...

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 ...

Six top factors to consider when selecting a flow meter
Water utilities rely on accurate and dependable flow measurement for critical process controls. Regulatory agencies also require flow monitoring and reporting, with specific accuracy limits. Flow metering technology is continually improving, and a variety of meter types and styles are available. Each flow meter application is unique, and flow meter selection should not be based on “low ...

Well monitoring for a water supplier - Case study
The municipality company, in city of Luebek, Germany, provides potable water for approximately 120,000 households, all pumped from more than 30 wells. These wells have water levels as deep as 160 meters. The water levels of these groundwater wells must be measured with the highest possible accuracy. Previously, the pressure probe's analogue output signals (4…20mA) that had been used ...

Low-Flow Groundwater Sampling- Techniques Improve Sample Quality and Reduce Monitoring Program Costs
Ground water is often sampled to determine its water chemistry, to see if the water is acceptable for human consumption, or to sec if industrial activity may have caused contamination. Sampling ground water from monitoring wells has traditionally involved "purging" the well to remove stagnant water that may not be representative of in situ ground water quality. Regulatory guidance often ...

Groundwater Monitoring of a Solid Waste Landfill in Germany
In Germany solid waste landfills are required to monitor the ground water on and around their premises and to regularly submit reports to the responsible environmental authority. It is the duty of the landfill operator to show that there is no strong negative effect on the ground water as it passes below the landfill. To be able to measure the impact of the landfill on the ground water quality, ...

Implications of observed and simulated ambient flow in monitoring wells
The authors of this paper present compelling evidence that conventional monitoring wells act as vertical conduits whenever vertical hydraulic gradients are present (i.e., at most sites). Vertical flow within wells due to natural hydraulic gradients not only makes it impossible to accurately define the vertical distribution of dissolved contaminants within the aquifer, but it can transport ...
