Cost-effective telemetry for agricultural applications
Rural areas with irrigation districts and small municipal water systems face distinctive issues because of their size and geography. Water shortages in irrigation districts, for instance, mean that farmers need the most accurate information possible to understand how the water they pump is being used. Relying on estimates, no matter how scientific, tends to yield unreliable numbers. And while ...

3 Reasons the Series PT-510 Excels in Well Water Measurement
In February we introduced our newest submersible pressure transducer, the Series PT-510. The Series PT-510 is an OEM-ready submersible transducer, with a maximum depth of 46 feet. Today, let’s look at three specific advantages of using the PT-510 in well water measurement. The size of the PT-510 is its first advantage in well water measurement. At less than an inch (0.9” / 21.9 mm) ...

Fluoride levels in drinking water and other surface water of an industrial area belt of Orissa State in India
The fluorosis problem along with endemicity characterised by high degree of industries releasing fluorides into the environment was studied to quantify the fluoride levels in the different water sources. The analysis showed that out of 17 tube wells monitored, three (17.65%) showed higher fluoride levels. Among the open well monitored, 17 (58.54%) had higher fluoride content out of 41. The ...

Why Is Water Level Monitoring Important?
Monitoring water levels can have numerous environmental benefits and is a popular measurement for a number of different industries and organisations. Below we will discuss some of the common applications water level monitoring devices, as well as some of the valuable insights that recording this can reveal. Remote water level monitoring Whereas water level monitoring used to be done by ...

Fold geometry model of Coyote hills segment of Puente hills blind-thrust system applied to interpretation of long-term water level data
Recent work by others along the Coyote Hills segment of the Puente Hills blind-thrust system has imaged the near-surface structural features generated by activity of that intrabasin fault. Published shallow seismic profiles near the south flank of the Coyote Hills indicate the blindthrust system is expressed by south-facing folding of Quaternary terrestrial sediments underlying the hills. ...

Assessing ongoing sources of dissolved‐phase polychlorinated biphenyls in a contaminated stream
Few studies assess the potential of ongoing sources of “fresh” polychlorinated biphenyls (PCBs) to aquatic systems when direct discharge to the environment has been eliminated. In the present study, the authors used single‐layered, low‐density polyethylene samplers (PEs) to measure total PCB concentrations, congener profiles, and enantiomeric fractions (EFs) in a contaminated stream and to ...

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 reaches and ...

LNAPL At Petroleum Product Terminal - Case Study
ABSTRACT BOS 200® was injected at a refined petroleum product terminal to remediate LNAPL in groundwater. Within one year after treatment, the site received a No Further Action status. CHALLENGES The remedial goal was to eliminate the reoccurrence of light non-aqueous phase liquid (LNAPL) which persisted with no apparent pattern. Annual fluctuations in groundwater elevation were ...

Fighting saltwater intrusion into groundwater supplies
As freshwater supplies around the world diminish, human intervention is needed to protect existing sources to slow the onset of water scarcity. One ongoing struggle is to preserve the water in underground aquifers, which cities often rely on for drinking water. Intrusion of saltwater into these underground supplies is rendering them unfit for consumption or irrigation. The rock and soil that ...

Bioremediation/natural attenuation continues after ISCO treatment
Scientists and engineers from the private sector and EPA are evaluating the potential for in situ bioremediation and/or natural attenuation to successfully treat residual soil and ground-water contamination after source-area in situ chemical oxidation (ISCO) treatment. The studies were prompted by concerns that the two treatment technologies may be incompatible due to detrimental impacts on ...

Pump Station call outs a thing of the past - Case Study
It’s 2:00 AM and a telephone rings in Eckville, Alberta. Rick McKinnon checks the display on his cell phone and groans. It’s another high level call out alarm from one of the town’s new sewage lift stations. He knows before he drives there that the system will be running on floats instead of the new ultrasonic level controller. Rick is Public Works Supervisor for the Town of ...

Biogas in Asia
The development of biogas production and monitoring has had many twists and turns, from its early days in Germany to the heady days of support through the Clean Development Mechanism (CDM). The fall in the price of carbon credits, which rewarded reduction in emissions of methane (CH4) - a potent greenhouse gas - and use of methane from waste as renewable energy, has hit Asia particularly hard. ...

Questions and answers on the Commission Communication `Towards a Circular Economy` and the Waste Targets Review
What is a circular economy? A circular economy preserves the value added in products for as long as possible and virtually eliminates waste. It retains the resources within the economy when a product has reached the end of its life, so that they remain in productive use and create further value. It may involve: Increasing the time products deliver their service before coming to the end of ...
