  • The importance of groundwater monitoring

    Groundwater monitoring is an essential element in any environmental information system. Based upon validated groundwater monitoring data, information is derived on which decisions can be made. Constant monitoring provides the necessary data input for your smart environment and is basically the basis of the decision making process concerning spatial planning and climate change adaptation. As in ...

  • Scottish Water Flow Monitoring Contracts

    Scottish Water commissioned HL in 2007 to deliver two separate flow monitoring contracts to help improve the water companies understanding of the yield and low flow conditions at several water supply catchments across Scotland. One project involved the installation of reservoir level, inflow flow gauges and recording raingauge devices in nine reservoir catchments in South West Scotland. Although ...

  • Hazardous waste and not, Baioni-Dicatech system

    The identification, characterization and restoration of contaminated areas now represent a big environmental issue, both at European and national level. In the major industrialized countries the issue of contaminated land has come out in all its gravity in the late seventies when, against a widespread awakening of environmental consciousness, important pollutions events emerged. Consequently, in ...

  • Monitoring Flow Rate in a Channel to Minimize Water Pollution

    Recently a wastewater management district in Cleveland contacted CAS DataLoggers to supply an automated monitoring solution for their environmental project. In most cities, sanitary sewers and storm sewers were separate, so that storm water was diverted into a nearby lake. However, Cleveland had only one sewer available, so all of the flow went to the ...

  • Portable Monitoring Instruments Solve Flow Rate Mystery

    The Glen Walter Sewage Collection System was built to service 1080 customers in 1989. At the time the population was 850 but by 1995 the sewage treatment plant had already reached capacity. Shawn Killoran took over the Operations Manger position in 1999 and, along with the Mayor and Council, he immediately had concerns about the excess flow. The Township started by video taping all of the lines ...

  • Monitoring Hydrocarbons in Bilge Water

    The Situation Various processes onboard ships, such as machinery wash-down, maintenance, and leakage generate oily wastewater. This contaminated water flow collects in the bilge of the ship. Marine diesel, lubricating oils, grease, as well as garbage may be present in bilge water. The bilge water is discharged overboard, with oil and grease concentrations in the discharged water limited ...

  • 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 ...

  • Monitoring of water node in wroclaw

    Background Wroclaw's water node has complicated structure. The river Odra has 3 main riverbeds and a lot of channels which are located in the centre of town. There are almost 100 hydro buildings which control flow of the water through the city and protect it against theflood. The great flood in 1997 proved that no one has control over it. Communication systems failure caused ...

  • Water quality monitoring with hydrolab MS5

    Background The Škocjan caves are a unique natural phenomenon located in south western Slovenia and are preserved as the Škocjan Caves Park under UNESCO protection. One of the most famous network of underground caves in the world, they were formed by the flow of the Reka River as it bored tunnels through the region’s limestone geology. The river first disappears underground just outside the ...
