Low-Flow Purging Reduces Management of Contaminated Groundwater
Purging a monitoring well prior to sampling removes stagnant water in the well casing and ensures collection of groundwater samples representative of formation water. Traditionally, a number of well casing volumes are removed (from three to five) and water stabilization parameters are monitored during removal of the casing volumes. Temperature, pH and specific conductance are routinely monitored ...

Difficulties and modifications in the use of available methods for hydraulic conductivity measurements in highly clogged horizontal subsurface flow constructed wetlands
Despite the fact that several authors consider the available measurement methods of hydraulic conductivity (ks) suitable for a good representation of the bed condition and clogging potential in horizontal subsurface flow constructed wetlands, others have questioned their adequacy. In this work, hydraulic conductivity measurements with conventional and modified methods were undertaken in two ...

Conductivity Measurement in high purity water samples below 10 microsiems/cm
High Purity Water Resistivity/ Conductivity Measurement Ultra-Pure Water without any chemical impurities will still have a conductivity because of the presence of H* and OH" ions due to the self-ionization of water. Ultra-pure water has a conductivity of 0.055 HSiemens'cm or a resistivity of 18.18 mQ-cm at 25 °C. In order to know the conductivity or resistivity of ultra-pure water it is ...

NMR Investigations in Coastal Ecosystems by Darya Morozov
Coastal ecosystems play an important role in interfacing between marine and terrestrial environments. These systems host complex dynamic processes associated with strong physical gradients between freshwater and saltwater, ground water and surface water, and between high and low permeability soils. Therefore, the structure and stability of coastal environments have a critical impact on ...

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 ...

Confined disposal facilities: History and trends
ABSTRACT Confined disposal facilities with filter layers have been used for disposal of dredged sediments for decades. Recent assessment of the environmental risk of contaminants in sediments has resulted in the use of lined confined disposal facilities. A case history outlines a contaminated sediment disposal facility designed with geosynthetics. Trends indicate more stringent requirements for ...
