  • The first monitoring well in Engbertsdijksvenen is a reality

    On Wednesday 20 December 2017, the first monitoring well of the groundwater monitoring network Engbertsdijksvenen was realised on the parcel of landowner Wilharms in Vriezenveen. This monitoring well serves to monitor the effects of the measures required for the Nature Objectives of the Engbertsdijksveen. One of these goals is the recovery of living high moor. In addition to this monitoring well, ...

  • Introduction to Fluorescence for Oil in Water Monitoring

    Fluorescence can be found in many applications throughout our day-to-day routines. Commercially, one of the most obvious uses is in fluorescent lighting. For this, fluorescence is used to emit light from a tube without the use of heat, unlike standard incandescent light bulbs that require a heated element. In this example, fluorescence also contributes to energy conservation efforts. At an ...

  • 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 ...

  • Surfactant-assisted oil-in-water monitoring

    A variety of common surfactants have been used to reduce fouling and enhance the performance of fluorescence-based oil-in-water monitors. Among the most effective are the alcohol ethoxylates with HLB values close to 12. Examples are SurfonicTM L24-9 (Hunstman, USA, HLB 13) and TergitolTM 15-S-7 (HLB 12.1). These surfactants readily convert heterogeneous oil/water mixtures into homogeneous, ...

  • Monitoring Water Resources Beyond Irrigation

    Over the past year, California’s governor has taken unprecedented action, requiring Californians to drastically cut potable urban water use. While the restrictions may seem harsh to some, it actually provides an opportunity for building managers and community association boards to implement an effective long-term water conservation program. And the result can be significant dollar savings. ...

  • 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 ...

  • Dust monitoring

    Generally, two different approaches are used to measure the amount of dust deposited on a surface; Determination of the soiling of a surface, by a change in its properties; Determination of the quantity of dust deposited, by weight. WHAT IS DUST? Dust is a generic term used to describe fine particles that are suspended in the atmosphere. Dust comes from a wide variety of sources, including soil, ...

  • Water Quality Monitoring for the “Big Four Parameters”

    Many different parameters can be measured in natural and artificial waters with sensors or via lab analysis. Each parameter effects water quality and the organisms that depend on the water for survival. Different states, monitoring agencies, and companies also place an emphasis on different water quality parameters to be monitored, depending on local conditions and mandates. For most water ...

  • Water monitoring as a safety feature for nuclear desalination

    It is widely accepted that the general safety approach for nuclear facilities is valid for a Nuclear Desalination Plant (NDP), thus IAEA standards and guides are applicable. The coupling of a NDP should be designed with the safety objective of ensuring that it results in no adverse effect on the Nuclear Power Plant (NPP) safety. The first objective (provisions of barriers) is complied with by the ...

  • Anglian Water selects Proam ammonia monitor

    Anglian Water (AWS) has selected the Proam ammonia monitor to provide continuous ammonia measurement on final effluent discharge where accurate and reliable measurement is required. One of the most recent installations is at Stanningfield WwTW situated near Bury St. Edmunds, in Suffolk. This is a small rural site receiving primarily domestic sewage. The site performs aerobic ...

  • 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 ...

  • Water quality monitoring following Hurricanes Katrina and Rita

    Following the passage of Hurricane Katrina, New Orleans was left with 80% of its land area flooded. In some locations, the flood waters were over 30 feet deep. In the heat and stagnation, the waters quickly became heavily polluted. Pump out operations began in early September 2005 to get the city dried out quickly. Lake Pontchartrain was the primary receiving water body. A variety of approaches ...
