Monitoring Environmental Quality

' In order to determine the effectiveness of actions to improve environmental quality it is necessary to be able to measure relevant environmental parameters at a level of detail which is accurate enough to distinguish the anticipated changes. However, the establishment and maintenance of monitoring systems is time-consuming and expensive and therefore the scale of such systems needs to be kept ...

Continuous water quality monitoring on Kolubara River

The first automated station for water quality monitoring located in Beli Brod on the Kolubara river has launched on July 2008. The station was established as the result of RHMSS participation in Twinning project financed by EU, where RHMSS was entrusted with the Component 2 of this project. Installed equipment continually records values of water level, temperature, pH, electroconductivity and ...

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 ...

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 ...

Monitoring Water Quality Runoff From a Coalmine

Intelligent Monitoring Solutions from dataTaker CAS DataLoggers provided the intelligent datalogging solution for an open-cut coalmine managing a high salinity water runoff into local retaining dams. The water from these dams could only be released into the local river system when it was of sufficient quality to have no effect on the irrigation of the surrounding farming district. ...

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 ...

Drinking water quality monitoring using trend analysis

One of the common quality parameters for drinking water is residual aluminium. High doses of residual aluminium in drinking water or water used in the food industry have been proved to be at least a minor health risk or even to increase the risk of more serious health effects, and cause economic losses to the water treatment plant. In this study, the trend index is developed from scaled ...

Topological clustering as a tool for planning water quality monitoring in water distribution networks

Topological clustering was explored as a tool for water supply utilities in preparation of monitoring and contamination contingency plans. A complex water distribution network model of Copenhagen, Denmark, was simplified by topological clustering into recognizable water movement patterns to: (1) identify steady clusters for a part of the network where an actual contamination has occurred; (2) ...

Identifying water quality monitoring stations in a water supply system

Despite good quality assurance and conformance to the standards at the treatment plants, water quality could vary considerably within the distribution network. As water flows through the pipe network, its quality undergoes various transformations due to many factors such as the properties of the finished water, pipe materials, water temperature, water age and low level of disinfectant residuals. ...
