Water Level Monitoring Articles

  • What are the main indicators of water quality?

    “Water is the driving force of all nature;” so said Leonardo da Vinci. The survival of our planet depends on the availability of water and the condition that it is in. It is therefore vital to make sure that it is able to provide a hospitable environment for those that live in it, and is free from harmful levels of substances for those that drink it. Not ...

  • Surface/bathing water monitoring (Denmark) - Case Study

    In order to find the possible fecal sources to the sporadic high concentrations of bacteria, the municipality of Hjørring (DK) has set up a BACTcontrol in the ditch to monitor the E.coli levels. For this purpose the BACTcontrol is built into a movable trailer and powered by solar panels. This allows the BACTcontrol to run continuously (6 samples per day) for 7-14 days depending on the ...

  • Signs You Need a New Water Pump

    Motor vehicles are built upon small parts doing big jobs. Consider your engine. It is likely the most important machine within your car, truck, or SUV, but it is not made up of one or two components, but thousands. Some engines have over 14,000 different parts to keep them operational. If just one of these parts, such as the water pump, fails, then the entire engine could grind to a halt. ...

  • PeCOD® Case Study #13 Airport De-Icing

    De-icing of aircrafts and airfield pavement is important to ensure the safety of passengers and cargo operators. These operations can have negative environmental impacts, due to the presence of ethylene glycol and propylene glycol, which contribute to high levels of BOD in surface water.  Regulations are in place to ensure that waste from de-icing operations are properly collected and ...

  • 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 ...

  • Exploring aeration-associated energy savings at a conventional water reclamation plant

    Aeration accounts for a large fraction of energy consumption at conventional water reclamation plants (WRPs). Older plants were designed when control techniques were relatively primitive and energy consumption was less of a concern. As a result, although process operations at older WRPs can satisfy effluent permit requirements, they can operate with excess aeration. In this study, we developed ...

  • Combining pressure management and energy recovery benefits in a water distribution system installing PATs

    Gravity can play a beneficial role in certain water distribution networks (WDNs), although sometimes high nodal pressures occur. Excessive pressure may lead to several negative effects regarding the network's operation and life. Thus water utilities are obliged to implement pressure management (PM) policies. Instead of just ‘destroying’ energy using conventional measures, there are other PM ...

  • Tracking the downstream impacts of inadequate sanitation in central Appalachia

    Poor sanitation in rural infrastructure is often associated with high levels of fecal contamination in adjacent surface waters, which presents a community health risk. Although microbial source tracking techniques have been widely applied to identify primary remediation needs in urban and/or recreational waters, use of human-specific markers has been more limited in rural watersheds. This ...

  • Determination of Flow Rates in part-filled Applications using the Radar Method

    Introduction The radar measurement method plays an increasingly important role in the water and wastewater field. This is particularly reflected by the "Metering outside of the medium" trend. Flow measurement using radar which enables contactless measurements thus becomes a major focal point. It features a wide range of applications and hence is useful as permanent measurement system for ...

  • Report documents effects of 40 years of groundwater withdrawal

    The cumulative effects of 40 years of groundwater withdrawals in the Houston-Galveston region are documented in a report from the United States Geological Survey. Decades of extensive withdrawals have caused the land to sink, or subside. The Houston-Galveston region is one of the largest areas of land surface subsidence in the U.S., according to the agency. Water withdrawals started as early as ...

  • Rhode Island Wastewater Plants Key To Water Quality Reversal

    Despite evidence that often points to the contrary, many bodies of water around the country stand as prime examples of how environmental quality can be improved with the proper will and effort. Take, for instance, Narragansett Bay, located on the north side of the Rhode Island Sound. Located near some of America’s oldest settlements, the bay has ...

  • Assessing future water supply and demand in a water-stressed catchment after environmental restrictions on abstractions

    The Ali Efenti catchment is a rural upstream subcatchment of the Pinios river basin in central Greece. The average annual precipitation in this subcatchment is relatively higher and groundwater recharge is relatively faster than in the rest of the river basin. Yet, seasonal water shortages occur due to the rapid increase of water abstractions in the summer months, mainly for crop irrigation. ...

  • Prediction of groundwater levels using evidence of chaos and support vector machine

    Many nonlinear models have been proposed to forecast groundwater level. However, the evidence of chaos in groundwater levels in landslide has not been explored. In addition, linear correlation analyses are used to determine the input and output variables for the nonlinear models. Linear correlation analyses are unable to capture the nonlinear relationships between the input and output ...

  • Groundwater level response to hydrogeological factors in a semi-arid basin of Beijing, China

    In this study, the mode of groundwater level fluctuations is analyzed by statistical approaches for 51 monitoring wells located in a semi-arid basin in Beijing from 1998 to 2013. Firstly, a geostatistical method was performed to characterize the spatial and temporal behaviors of data sets and analyze the responding mechanism of groundwater level to hydrologic features using the Geostatistics ...

  • The role of packaged water in meeting global targets on improved water access

    Packaged water (as either refill, bottled, or sachet water) has become an important element of water security in many low- and middle-income countries, owing to poor reliability and lack of piped water infrastructure. However, over time and across countries, the Demographic and Health Surveys monitoring program has inconsistently classified packaged water components as either improved or ...

  • In a Future of Extremes, Southeastern States Must Have Water Management Policies

    Introduction Climate change is expected to have an impact on every type of weather phenomenon that occurs on Earth.  The nature and magnitude of the impact varies with the location on the planet and the type of weather in question, and coupled climate-weather models, have different degrees of uncertainty about different types of weather (though these models are dramatically improving ...
