  • 3 Water Utilities that Lowered their Arsenic Levels with AdEdge

    Finding an appropriate solution to address arsenic in raw water can be challenging for utilities. Studies have shown that when ingested in high concentrations, it is linked to cancer in the skin, lungs, bladder and kidney, and can cause significant skin changes, such as thickening and pigmentation, as well as other health issues. For this reason, the ...

  • Repurposing Composting Infrastructure

    A Vermont solid waste district utilized a defunct biosolids composting site to create capacity for processing food waste. The Vermont legislature instituted a progressive ban on organics in landfills via Act 148 in 2012. The Act includes the provision that transfer stations/drop-off facilities must accept food scraps by July 1, 2017. The Lamoille Regional Solid Waste Management District (LRSWMD) ...

  • Why You Should Monitor Groundwater?

    What is groundwater? Groundwater is water that is stored below the earth’s surface. When rain or other sources of water come into contact with the ground, the majority of it travels below the surface. Though much of this moisture is then absorbed by plants or returned to the atmosphere (through infiltration), some water will travel deeper beneath the surface – where it ...

  • Why are we monitoring nutrients at different depths?

    Recently, LG Sonic introduced the MPC-Lab, an innovative monitoring buoy that can monitor algae, physico-chemical variables, and even nutrients such as nitrogen and phosphorus in near real-time and at different depths in a body of water. Combined with our other monitoring tools, this system offers a unique way to detect the spatial and temporal patterns of nutrient concentrations which play a ...

  • Locating Leaks for Cooling Water Systems

    This article illustrates how to locate leaks on cooling water systems in loud, industrial environments like Nuclear or Coal power generating plants without digging or putting anything inside the pipeline.  Infrared-Energy Pattern Analysis (IR-EPA) works on all pipeline sizes and all pipeline materials because it identifies the water outside the pipeline instead of listening for leak noises ...

  • Selection of monitoring locations for storm water quality assessment

    Storm water runoff is a major contributor to the pollution of receiving waters. Storm water characteristics may vary significantly between locations and events. Hence, for each given location, this necessitates a well-designed monitoring campaign prior to selection of an appropriate storm water management strategy. The challenge for the design of a monitoring campaign with a given budget is to ...

  • A New Way to Locate Seeps Into Surface Waters

    How can we determine where groundwater is seeping into rivers and bays?  Knowing seep locations can help with selecting sampling locations, identifying contaminant sources, determining whether contamination is historic or on-going, and designing remediation.  Historically, methods for locating seeps have been limited.  Due to cost, sampling can only be done at a few ...

  • Struvite Formation, Prediction and Locations.

    Struvite formation occurs when magnesium, ammonium and phosphate hexahydrate whose elemental composition of magnesium ammonia and phosphate forms in water combine in the exact chemical formulation as expressed by equation Mg2+ + NH4+ + HPO42- + 2H2O MgNH4PO4•6H2O + H+. This is the chemical term and formulation for struvite. This article goes over how Struvite is formed, the parameters for ...

  • Assessment of relative impact of reservoir location

    Reallocation of reservoir storage capacity for different water use purposes is regarded as one of the representative strategies for supplying water for human and environmental needs under the difficult situation of new reservoir construction. However, there are impacts of reservoir storage reallocation on river/reservoir systems because each reservoir in a multiple reservoir system is operated ...

  • Locating pipes and cables case study

    GPR can be used to determine the location and depth of metallic, non-metallic, plastic, concrete and asbestos-concrete utilities, and cables (power, signal, etc.) Locating of  City Utilities The VIY3-300 GPR was used for locating of city utilities (water, gas, sewer, etc.). This profile shows city utilities at a depth of 1.2 and 2.0 meters (wave speed is 130 meters per ...

  • Geostatistical techniques for approximate location of pipe burst events in water distribution systems

    This paper focusses on the customisation and further enhancement of the recently developed data-driven methodology for the automated near real-time detection of pipe bursts and other (e.g. sensor faults) events at the district metered area (DMA) level. Assuming the availability of pressure/flow data from an increased number of sensors deployed in a DMA, the aim is to: (i) overcome the ...

  • Integrated sensing technologies for detection and location of leaks in water distribution networks

    Water distribution networks (WDNs) are infrastructure systems that have high socioeconomic values, for which efficient operation and management are required to ensure minimal amounts of waste which can be represented in the form of leaks. Leak detection is considered as one of the challenges faced by municipalities operating WDNs because it either involves shutting down the system or requires ...

  • Sensor placement for leak detection and location in water distribution networks

    The performance of a leak detection and location algorithm depends on the set of measurements that are available in the network. This work presents an optimization strategy that maximizes the leak diagnosability performance of the network. The goal is to characterize and determine a sensor configuration that guarantees a maximum degree of diagnosability while the sensor configuration cost ...

  • Water quality of a stream receiving industrial effluents, located in the Brazilian Northeast

    Industries, as a source of pollution, have a considerable impact on water resources due to the diversity in the composition of their effluents. The Mussure Stream was chosen for this study because it flows across the industrial district of Joao Pessoa, in Northeast Brazil, and is the main receiver of liquid effluents, which are disposed into the stream almost exclusively without adequate ...
