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 ...

The Perspective of Microbiotests Application of Surface Water Monitoring and Effluent Control in Estonia
Abstract: In Estonia, traditional chemical monitoring of surface water and effluents is performed but bioassays are not used as monitoring tools. Furthermore, the expediency of application of toxicity tests to surface water monitoring is questionable. The main aim of this study was to test the feasibility of using microbiotests in the biomonitoring of surface waters and effluents. The ...

Application of ion-sensitive sensors in water quality monitoring
Abstract: Within the last years a trend towards in-situ monitoring can be observed, i.e. most new sensors for water quality monitoring are designed for direct installation in the medium, compact in size and use measurement principles which minimise maintenance demand. Ion-sensitive sensors (Ion-Sensitive- Electrode – ISE) are based on a well known measurement principle and recently some ...

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 ...

Ground Water Monitoring of the City of Hamburg, Germany
Reference Project: Ground Water Monitoring of the City of Hamburg, Germany Hamburg is the second-largest city in Germany with approx. 4.3 million inhabitants. The Hamburg Environmental Authority manages a constantly growing data base containing data from more than 10.000 ground and surface water monitoring points. With the help of this data base the authority is able to provide information about ...

Partitioning and availability of sediment-bound metals following final sewage effluent release to a lowland river
A simple partitioning scheme was used to assess the partitioning and behaviour of copper, cadmium, iron, lead and manganese within the surface waters and sediments of the River Yare, Norfolk, UK, following the discharge of final effluent to the water course from municipal sewage treatment works (STW). Sewage effluent discharges were shown to increase metal concentrations and complexation ...

EQuIS milestone
EQuIS now contains over 15 million chemical/physical discrete monitoring results after the recent completion of the EDMS (Closed Landfills) database migration. Growth for other MPCA Remediation and Solid Waste programs will depend on the rate that labs and contractors adopt the new standard lab and field EDD submittal formats and on associated location establishment. Groundwater and surface water ...

On-line monitoring of enzymatic activities in water and water resources
On-site detection of enzymatic activities has been suggested as a rapid surrogate for microbiological pollution monitoring of water resources (e.g. using glucuronidases, galactosidases, esterases). Due to the possible short measuring intervals enzymatic methods have high potential as near-real time water quality monitoring tools. This presentation describes the successful realization and ...

Estimation of surface water quality in a Yazoo River tributary using the duration curve and recurrence interval approach
Pollution of surface water with harmful chemicals and eutrophication of rivers and lakes with excess nutrients are serious environmental concerns. This study estimated surface water quality in a stream within the Yazoo River Basin (YRB), Mississippi, USA, using the duration curve and recurrence interval analysis techniques. Data from the US Geological Survey (USGS) surface water monitoring ...

Protoc TOC succes at Manchester Airport
The case study outlines the installation of Protoc TOC analysers at Manchester International Airport used for continuous surface water quality monitoring and control. The Protoc TOC instrument manufactured in the UK by Pollution & Process Monitoring Ltd was rigorously tested and was selected for a number of installations at critical drainage locations which have proved the reliability of the ...

Aminomethylphosphonic acid (AMPA) has low chronic toxicity to Daphnia magna and Pimephales promelas
Aminomethylphosphonic acid (AMPA) is the simplest member of a class of compounds known as aminomethylenephosphonates and the only environmental metabolite measured in significant amounts during the degradation of the herbicide glyphosate in soil. However, there are additional sources of AMPA in the environment, originating from organic phosphonates which are used in water treatment to inhibit ...

Using PRTR database for the assessment of surface water risk and improvement of monitoring in Japan
In April 2003, the first PRTR (Pollutant Release and Transfer Register) was published in Japan. It is shown how the PRTR can be used to improve environmental risk assessment with the objective of reducing risk to ecosystem integrity and human health. By examining the superposition of all chemical releases into rivers, high levels of several contaminants are uncovered. Most of these chemicals have ...

Estimating discharge in rivers through the combined use of dimensionless isovels and point velocity measurements
This paper presents a procedure for estimating discharge in a river cross-section based on the combined use of dimensionless isovels and point velocity measurements. Specifically, taking the Biot–Savart law on the magnetic field induced by an electric current in a wire as their basis as already done by other researchers, the authors propose a new formulation of the relationship characterizing ...

Quantitative real-time PCR does not reliably detect single fecal indicator bacteria in drinking water
The microbial quality of drinking and environmental water is usually determined by culture-based detection of fecal indicator bacteria according to ISO reference methods 16649-1 and 7899-2, respectively. Because of an increasing demand for rapid, culture-independent methods, we tested three quantitative polymerase chain reaction (qPCR) approaches for the simultaneous detection of both, ...

How to improve water quality in Europe
Policy briefs provide decision-makers with recommendations for action Toxic substances from agriculture, industry and households endanger water quality in Europe -- and by extension, ecosystems and human health. As part of the SOLUTIONS project, over 100 international scientists have developed methods and practical solutions for identifying pollutants and assessing the risks posed by chemical ...

Hydrochemical evaluation of surface water quality and pollution source apportionment in the Luan River basin, China
In the context of rapid economic growth in China, hydrochemical characteristics of stream water quality are being influenced by a variety of natural and anthropogenic inputs. We determined 10 hydrochemical parameters of the surface water at 29 monitoring sites in the Luan River basin of northern China during 2007–2009. Water quality hydrochemistry was evaluated using fuzzy comprehensive analysis ...

A large‐scale field trial of thin‐layer capping of PCDD/F‐contaminated sediments: Sediment‐to‐water fluxes up to five years post‐amendment
The longer‐term effect (3‐5 y) of thin‐layer capping on in situ sediment‐to‐surface water fluxes was monitored in a large‐scale field experiment in the polychlorinated dibenzodioxin and dibenzofuran (PCDD/F) contaminated Grenlandfjords, Norway (four trial plots of 10,000 to 40,000 m2 at 30 to 100 m water depth). Active caps (designed thickness 2.5 cm) were established in two fjords, consisting ...
