  • Online discharge measurement with OTT SLD

    Background For the economic management of the waterways between Elbe and Oder it is essential to know the discharge of these rivers at defined locks. The authority for water and navigation (WSA) in Lauenburg operates hydrological stations for the measurement of water level and discharge to effectively regulate the water flow at the locks in Plau and Malliß ...

  • Monitoring Environmental Quality

    ' In order to determine the effectiveness of actions to improve environmental quality it is necessary to be able to measure relevant environmental parameters at a level of detail which is accurate enough to distinguish the anticipated changes. However, the establishment and maintenance of monitoring systems is time-consuming and expensive and therefore the scale of such systems needs to be kept ...

  • Online flow measurement

    Background The undershoot weir in Hohensaaten was built in 1913. It has three openings and regulates the discharge from the Oderbruch and from the Finow canal into the Hohensaaten-Friedrichsthaler-waterway. Moreover, it protects parts of the Oderbruch against Oder floods. The weir controls the waterlevels in the Havel-Oder-waterway and in the reach of Niederfinow- Hohensaaten. ...

  • A triple play for CETCO oilfield services - treating hydrostatic test water

    CETCO Oilfield Services was selected to treat and discharge approximately 150,000 barrels of hydrostatic test water in Houston, Texas. The water was treated and discharged into a nearby stream under a National Pollutant Discharge Elimination System (NPDES) permit from the State of Texas. The permit also required that there be no discharge of floating solids or visible foam, no discharge of ...

  • Ocean outfall plume characterization using an autonomous underwater vehicle

    A monitoring mission to map and characterize the Point Loma Ocean Outfall (PLOO) wastewater plume using an Autonomous Underwater Vehicle (AUV) was performed on 3 March 2011. The mobility of an AUV provides a significant advantage in surveying discharge plumes over traditional cast-based methods, and when combined with optical and oceanographic sensors, provides a capability for both detecting ...

  • Heat From Wastewater

    When it comes to using wastewater heat from channels, provision and evaluation of hydraulic and thermal wastewater data is urgently needed prior to planning and implementation of facilities. Knowing the wastewater temperatures as well as the flow rates - particularly as dry weather discharge – is an indispensable component. It is therefore essential to carry out preliminary measurements ...

  • Dynamics and environmental risk assessment of the herbicide glyphosate and its metabolite AMPA in a small vineyard river of the Lake Geneva catchment

    The use of pesticides may lead to environmental problems, such as surface water pollution, with a risk for aquatic organisms. In the present study, a typical vineyard river of western Switzerland was first monitored in order to measure discharged loads, identify sources and assess the dynamic of the herbicide glyphosate and its metabolite AMPA. Second, based on river concentrations, an ...

  • Rapid on-site analysis of fats, oil and grease (FOG)

    It is estimated that 23-28% of Sanitary Sewer Overflows (SSOs) are due to Fats, Oils and Grease (FOG) or as much as 19 million gallons from 1998 to 2001 (State of North Carolina, 2004). Our increasingly mobile society has led to a decrease of cooking at home and a significant growth in the commercial food sector. This, on top of other industries such as metal processors, meat packers, cosmetic ...

  • LEGAL LOOKOUT: EPA Proposes Amendment to SPCC Plan Requirements

    On Dec. 12, 2005, the EPA proposed to amend Spill Prevention, Control, and Countermeasure (SPCC) plan requirements to reduce the regulatory burden these requirements impose on covered entities. The agency also released a document entitled SPCC Guidance for Regional Inspectors to assist regional inspectors in assessing a facility's implementation of SPCC requirements. As such, the document is an ...

  • Miller Argent case study

    On the hills above Merthyr Tydfil, Miller Argent is undertaking a highly ambitious land reclamation scheme that is also involving the extraction of coal by opencast methods. Known as the 'Ffos-y-fran Land Reclamation Scheme', this is the third and final phase of the East Merthyr Reclamation Scheme which is expected to run for another 17 years. The reclamation works will include the removal of ...

  • Aggressive dewatering aids concrete rehab at Abitibi

    An enormous volume of water passes through the Abitibi Canyon Generating Station every hour of every day. In order to complete critical concrete repairs on the hydro power station, general contractor The Barclay Construction Group needed to find a way to pump and discharge almost 30 million gallons of water in a 500-metre section of the river upstream from the station in under 30 hours. Aquatech ...

  • Temporal variability of two contrasting transient pollution events in a pastoral stream

    Two transient pollution events were monitored in a pastoral stream in southwestern Kenya to evaluate their relative contribution to diffuse pollution. Peak loads of pollutants during storm-induced transients were within 3–4 orders of magnitude higher than the short-lived (30–60 minutes) diurnal episodes provoked by in-stream activities of people and livestock. Transient yields were striking ...

  • Alaska - Anadarko Oil Camp case study

    The "North Slope" of Alaska is one of the harshest environments in the world to survive in, let alone work in, on a daily basis. Temperatures can reach -70 degrees F and wind chill factors can reach -100 degrees F. The "Slope" is home to thousands of oilfield workers, many of who live in portable camps located in extremely remote locations. In such an environment, equipment must be reliable, ...

  • Natural Attenuation in Soils

    Introduction Surface and subsurface soils have different characteristics in natural attenuation. Mobile contaminants in subsurface soils diffuse into soil vapor and aqueous phase and thus are relatively easily subject to natural subsurface processes that can attenuate these contaminants. Most high-molecular-weight (persistent) organic and many inorganic contaminants will be immobilized in the ...
