  • Dynamic soft sensors for detecting factors affecting turbidity in drinking water

    Effective monitoring of water quality is critical for water safety. In particular, online monitoring based on modeling is useful in several applications such as process assessment, hazardous event detection or common fault diagnostics in the water processes. Soft sensors have lately established themselves as a good alternative for different tasks of process control such as the acquisition of ...

  • Best management practices (BMPS) for discharging water from a construction site

    Having problems on your job site with regulations related to pumping water from your site? Discharge water may carry harmful compounds that can, and have affected our water quality and the ecosystem, hence the environmental agencies concerns. When pumping from dewatering systems, storm water management ponds (SWMPs), excavations or trenches, or any form of surface runoff, BMPs are needed to ...

    Morgan Est is constructing a tunnel to carry high voltage electricity cables between two electrical substations.  The tunnel will mostly be excavated in Chalk, with some excavation occurring in the Thanet Sands. ESI was appointed as Morgan Est’s environmental consultant for the project and has managed liaison between Morgan Est, regulators and other stakeholders over the last four ...

  • In-situ quality monitoring station in Lower Saxony

    Background 'Duemmer' is a shallow lake in the south-west of Lower Saxony; through the lake flows the river 'Hunte'. The catchment area spans 426 km2. With a surface of 12.4 km2 and an average depth of 1.1 m there is a water volume of approx. 14 million m3. Large parts of the lakeside are a nature reserve and the lake is a popular local recreation area. The lake suffers from strong nutrient ...

  • Effects of highway construction on stream water quality and macroinvertebrate condition in a Mid-Atlantic Highlands watershed, USA

    Refining best management practices (BMPs) for future highway construction depends on a comprehensive understanding of environmental impacts from current construction methods. Based on a before-after-control impact (BACI) experimental design, long-term stream monitoring (1997–2006) was conducted at upstream (as control, n = 3) and downstream (as impact, n = 6) sites in the Lost River watershed of ...

  • Water Quality Monitoring and Testing Using an Environmental Logger

    Intelligent dataTaker System from CAS DataLoggers Water disruptions typically occur after a large amount of water has rapidly collected in a catchment area. As a result this water is subject to continual monitoring and testing for a variety of chemical and biological agents as well as clarity, rate of movement, and water levels for environmental management. Turbidity, conductivity, ...

  • Monitoring Water Quality Runoff From a Coalmine

    Intelligent Monitoring Solutions from dataTaker CAS DataLoggers provided the intelligent datalogging solution for an open-cut coalmine managing a high salinity water runoff into local retaining dams. The water from these dams could only be released into the local river system when it was of sufficient quality to have no effect on the irrigation of the surrounding farming district. ...

  • Removal of Microorganisms from Domestic Greywater Using a Recycling Vertical Flow Constructed Wetland (RVFCW)

    ABSTRACTThe reuse of greywater (GW) is an attractive addition to water management options. One of the major concerns limiting GW reuse is the possible presence of harmful microorganisms. In addition to total coliform organisms, enteric organisms (Salmonella, Shigella and poliovirus Type 1 Cryptosporidium, Giardia) and opportunistic pathogens ( Staphylococcus aureus and Pseudomonas aeruginosa) may ...

  • Unique Chinese wetland park monitors water 24/7

    Project background The Deyang area in southwest China was struck hard by an earthquake in 2008. Since then, reconstruction has taken place with a tremendous speed and the urban population grew exponentially. Due to this urbanisation, the city’s water supply system can not meet its rapidly growing water demand. Currently, two-thirds of ...

  • Seatac airport third runaway

    Active Treatment with 1% ChitoVan™ Chitosan Acetate The west side of Sea-Tac airport was widened by adding 11 million cubic yards of fill dirt to create the 3rd runway. Because the west side of the airport drains to Miller Creek, a protected NW stream, all of the construction stormwater had to be captured and treated prior to discharge. During the project over 5 billion gallons of ...

  • Water quality and quantity assessment of pervious pavements performance in experimental car park areas

    Pervious pavements have become one of the most used sustainable urban drainage system (SUDS) techniques in car parks. This research paper presents the results of monitoring water quality from several experimental car park areas designed and constructed in Spain with bays made of interlocking concrete block pavement, porous asphalt, polymer-modified porous concrete and reinforced grass with ...

  • Near-infrared spectroscopic assessment of contamination level of sewage

    We examined the use of near infrared (NIR) spectroscopy as a rapid technique for the evaluation of sewage quality. Influent water samples, primary sedimentation tank water samples, and final effluent water samples were collected from sewage treatment facilities in Nagoya, Japan and their NIR spectra obtained. Partial least squares (PLS) models for total phosphate (TP), total nitrogen (TN), ...

  • Accumulated state assessment of the Peace‐Athabasca‐Slave River System

    Effects‐based analysis is a fundamental component of watershed cumulative effects assessment. This study conducted an effects‐based analysis for the Peace‐Athabasca‐Slave River System, part of the massive Mackenzie River Basin, encompassing 20% of Canada's total land mass and influenced by cumulative contributions of the W.A.C. Bennett Dam (Peace River) and industrial activities including oil ...
