River water monitoring. Measurement of chromium III and VI - Case Study
Riachuelo in Buenos Aires is one of the most contaminated rivers. Argentina Government started an initiative cleaning this river. The first step was to size the problem and measure the most dangerous inorganic matter. Continuous measurements of Chromium should help to understand and size the problem of pollution. Application Challenges: Measurement of CrIII and CrVI in one measurement step. ...

Water quality of lowland, permeable Chalk rivers: the Frome and Piddle catchments, west Dorset, UK
This paper provides a baseline interpretation of extensive hydrochemical characteristics of UK Chalk catchments based on the Frome/Piddle (west Dorset), a major component of the LOCAR (Lowland Catchment Research) programme. It examines a wide range of chemical determinands using data from two long-term (1979–2000) river water monitoring sites. The water quality of the Frome and Piddle is very ...

Receiving water body quality assessment: an integrated mathematical approach applied to an Italian case study
This study presents a basin-scale approach to the analysis of receiving water body quality considering both point and non-point pollution sources. In particular, this paper describes an extensive data gathering campaign carried out in the Nocella catchment, which is an agricultural and semi-urbanised basin located in Sicily, Italy. Two sewer systems, two wastewater treatment plants and a river ...

Organic sum parameters for river monitoring
The purpose of river monitoring is to have an early warning system for chemical accidents with the consequence of water pollution through hazardous chemical substances. The real objective goes even further because the early warning system is intended for protecting the sensible drinking water resources. River monitoring stations have been established along rivers around the world. Today there is ...

Study of the distribution of dichlorobenzenes in sediment and water of Suquia River basin (Cordoba-Argentina) by an optimised SPME-GC-MS procedure
Three dichlorobenzene isomers (DCBs) were monitored in water and sediment from the Suquia River basin by Solid Phase Microextraction (HS-SPME), coupled to Gas Chromatography?Mass Spectrometry (GC?MS). DCBs were not detected in water or sediments corresponding to the upper basin. Pollution with DCBs became evident when the river flows through small cities. As expected, Cordoba city causes the most ...

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 ...

Spatial variation of waterborne
Escherichia coli – implications for routine water quality monitoringEscherichia coli are often used as faecal indicator bacteria (FIB) to provide a measure of microbial pollution in recreational and shellfish harvesting waters. However, although model forecasts for predicting the concentrations of FIB in surface waters are becoming more robust, they suffer from an inconsistency in quantification methods and an understanding of the spatial variation of FIB within ...

Flood Monitoring with Radar Water Level Sensor
Application Problem: For a flood monitoring application, the customer required a solution to accurately monitor the level of a river, and be able to measure the river’s dry bed conditions. Application History: Solutions from several level sensor brands couldn’t detect the river’s dry bottom conditions, making them unsuitable for the application. Solution: ABM’s ...

National Hydrometeorological Measuring Network Portugal - Case study
Irrigation of agricultural areas is of essential importance in Portugal. A high number of water reservoirs is maintained for that purpose. One of the responsibilities of APA, the portuguese environmental agency, is to have the total real-time view about all of the portuguese water resources. A high number os measuring stations is necessary to fulfill that ...

NPS, Eastern River and Mountains Network - Case Study
Overview Since 1999, the National Park Service has conducted long-term ecological monitoring designed to identify and monitor conditions of their highest priority natural resources. The Eastern Rivers and Mountains Network is one of 32 networks formed to implement this integrated monitoring program which is tailored to specific needs of parks located in similar environmental settings. Due to its ...

ITOXcontrol safeguards intake Romanian drinking water - Case Study
The Romanian water supply company Apavital has installed a monitoring station to safeguard the intake of water from the river Prut. The monitoring station is part of an integrated monitoring that signals sudden changes in the water quality of the rivers, enabling Apavital to take appropriate measures, in the worst case a stop of the intake. The iTOXcontrol is developed by the Dutch company ...

Reconstruction of river water quality missing data using artificial neural networks
The monitoring of river water quality is important for human life and the health of the environment. However, water quality studies in many parts of the world, especially in developing countries, are restricted by the existence of missing data. In this study, the efficiency of the multilayer perceptron (MLP) and radial basis function (RBF) networks for recovering the missing values of 13 ...
