  • Abandoning Monitoring Wells: Safety Issues

    Monitoring wells are typically constructed to gauge the extent of contamination, assess water quality and conduct other hydrogeologic studies. Depending on its objective, the monitoring well may remain in use or may be abandoned permanently. When declared inactive, the well is many a times left as it is. Open unused wells are hazardous to life and environment: • Contamination may spread from one ...

  • Simultaneous determination of PM fractions, particle number and particle size distribution in high time resolution applying one and the same optical measurement technique

    Abstract The Fidas fine dust monitoring systems comprise an optical aerosol spectrometer, which is characterized by very good instrument characteristics, and utilize a sophisticated approach to convert the measured information on particle number and particle size into mass concentrations. As monitoring of PM requires reliable and quality-controlled performance of the measuring systems, ...

  • Arctic Polar Research - A Global Responsibility

    Due to climate change and geopolitical trends, the Polar Regions (particularly the Arctic) are increasingly becoming the focus of scientific, political, and economic interests. Much of the global climate is driven by forces that originate in the Arctic. The Arctic sea ice is receding faster than climate models have predicted, and the movement of freshwater into and around the Arctic plays an ...

  • Two Detector Solution to Analyzing Sulfur

    Sulfur compounds are reactive, corrosive to pipes, and destructive to catalysts in petroleum refineries. Sulfur emission are strictly regulated globally. When released into the atmosphere sulfur dioxide converts to sulfuric acid resulting in adverse effects on human health and the environment. Sulfur detection is found useful in many other industries; therefore, detection of sulfur compounds in ...

  • Reduced Emissions for Landfill Gas Installations

    The use of landfill gas as a source of renewable energy is increasing. For environmental and safety reasons, the owners of the waste storage sites have to strictly monitor and control the construction, operations, and emissions generated. Sulzer offers solutions to control these emissions within the limits given by the government. Landfill gas is similar to natural gas, but it is created by ...

  • A Critical Evaluation of the South African Air Quality Offsets Guideline

    There is wide recognition in South Africa to the link between the quality of life and quality of the air we breathe. The Department of Environmental Affairs (DEA) attempts to improve air quality through two key regulatory tools; emission limits, which regulate the maximum concentration of certain pollutants permissible within certain, ‘listed’ industrial stacks or vents, and ambient ...

  • Optimal groundwater contamination monitoring using pumping wells

    This study presents a new method for selecting monitoring wells for optimal evaluation of groundwater quality. The basic approach of this work is motivated by difficulties in interpolating groundwater quality from information collected for only few sampled wells. The well selection relies on other existing data relevant to contaminant distribution in the sampling domain, e.g. predictions of ...

  • San Juan Island well production and tank level monitoring case study

    San Juan Island is a popular resort destination whose population fluctuates with the season and the arrival of Orca whales and salmon runs. To get to the island, you must first drive an hour north of Seattle to the city of Anacortes. From there you take a two-hour ferry ride through a 130 island group to arrive at the 20 mile San Juan Island, which is at the waterway entrance to Puget Sound. Bob ...

  • A method for reducing purge volumes in deep monitoring wells: a purging experiment.

    Regulatory agencies often require three well casing volumes or more be purged prior to collection of groundwater samples for chemical analysis. Costs are high for testing and disposing of potentially hazardous purge water; therefore, efforts must be made to minimize waste-water volume while obtaining representative groundwater samples. Lockheed sponsored a purge experiment on two deep monitor ...

  • Importance of discrete-zone monitoring systems in fractured-bedrock wells -- A case study from the University of Connecticut landfill, Storrs, Connecticut

    Monitoring of hydraulic head is an important part of many hydrogeologic investigations because it is used to determine the rates and directions of ground-water flow. In unconfined aquifers, open-hole water levels can be used to establish meaningful conceptual models of ground-water flow. In heterogeneous fractured-rock aquifers, however, where the hydraulic head can be different for each fracture ...

  • Gas Detection and Monitoring Systems

    In greenhouse applications, the accurate measurement of a number of environmental parameters such as carbon dioxide concentration, temperature, light intensity, water, humidity, pH and nutrient levels using sophisticated sensors is used to create a controlled environment for optimising plant growth rates while minimising energy usage. Carbon dioxide concentration is also one of the best ...

  • Latin America well-positioned for CDM

    The coastal desert of Colombia’s La Guajira state is a world away from Kyoto, the temperate Japanese city where representatives of 159 countries in 1997 signed the Kyoto Protocol on reducing greenhouses gases. The Caribbean laps against rickety settlements. Herds of goats range across scorching sands. Months, whole years, pass without rain. But Kyoto is well known to the inhabitants of La ...


  • How well does my filter work?

    Contamination control is the key to a cost-effective maintenance operation for hydraulic or engine systems. You depend on your filters, whether hydraulic, lube or fuel, to keep your fluids clean, to keep maintenance costs down, and to ensure reliable operation. At some point, you probably will ask yourself whether or not your filters are really working and doing what they were designed to do. ...
