Risk analysis of seasonal stream water quality management
Seasonal discharge programs, which take advantage of temporal variation of stream assimilative capacity, are cost effective. However, these seasonal discharge control programs should not increase the risk of water quality violations. A method is presented to estimate the allowable pollutant loads under both seasonal and non-seasonal discharge control programs for a single discharger that ...

Water quality management in the Balabandere Creek catchment
Understanding hydrological and hydrochemical processes has become increasingly more challenging with high rates of population growth and subsequent alteration of the environment. In addition to maintaining monitoring networks to assess the general state of water quality, detecting trends, and computing pollutant transport, process-level information is needed to evaluate factors that affect the ...

Analysis of key aspects of the dispersion of industrial wastewaters to delimit environmental mixing zones
In the VERTITOX research project (018/RN08/02.1), where the Principal Researcher (IP) of this application took part, a methodology for delimitation of environmental mixing zones of urban and industrial discharges was developed. That work allowed verification of the existence of critical issues in establishing the extent of these areas. Such issues lie in the statistical treatment of the ...

Water quality management for domestic rainwater harvesting systems in Fiji
Health risks from drinking rainwater are relatively small in the developing world context, but action is needed to ensure water safety. Water safety plans (WSPs) use an approach to manage water quality that has shown signs of success with public and communal water supplies, but relatively little research has been done to investigate the application of WSPs to self-supply systems. The aim of ...

Principles for the application of the cost-effectiveness analysis in water quality sector
Cost-effectiveness analysis (CEA) provides useful information for the cost and the environmental effectiveness of alternative management options in realising a given environmental goal. The purpose of this paper is to present factors that could be considered essential for the identification of the most cost-effective combination of the measures for water quality management. The reviewed ...

Drinking Water Quality
The quality of drinking-water is a powerful environmental determinant of health. Drinking-water quality management has been a key pillar of primary prevention for over one-and-a-half centuries and it continues to be the foundation for the prevention and control of waterborne diseases. Water is essential for life, but it can and does transmit disease in countries in all continents – from the ...

Water quality management of aquifer recharge using advanced tools
Managed aquifer recharge (MAR) with recycled water or other alternative resources is one of the most rapidly growing techniques that is viewed as a necessity in water-short areas. In order to better control health and environmental effects of MAR, this paper presents two case studies demonstrating how to improve water quality, enable reliable tracing of injected water and better control and ...

Platypus Collects Water Quality Data in Record Time with Robotic Boats and In-Situ Equipment
Overview Hired to monitor runoff from intensive greenhouse agriculture in the Netherlands, Platypus uses robotic boats and Aqua TROLL 600s to gather in a matter of days water quality data that otherwise would have taken weeks or months to collect. Challenge As population density increases, many countries wrestle with water quality management. The problem is particularly acute in the Netherlands, ...

Access, monitoring and intervention challenges in the provision of safe drinking water in rural Bihar, India
This practical paper addresses the vital gap in water quality monitoring in Bihar. The study addresses an institutional weakness in the area of water quality management in rural Bihar, India. The study focuses on the role of access as a vital component in addressing water quality monitoring and interventions that has a huge impact on protecting community health in areas severely contaminated with ...

Fate of selected pharmaceuticals and their metabolites in soil aquifer treatment
Through a series of long-term column experiments, the fate of three common pharmaceuticals (carbamazepine (CBZ), diclofenac, and indomethacin) and their major phase I metabolites in soil aquifer treatment (SAT) were monitored. CBZ concentration increased by a factor of two (from 37 to ca. 70 ng/L) regardless of the treatment conditions, and its metabolites, ...

Surface water quality management using an integrated discharge permit and the reclaimed water market
Water quality trading is a sustainable framework for surface water quality management. It uses discharge permits to reduce the total treatment costs. For example, the case of Gharesoo River in Iran shows that the nitrogen permit market between point and non-point sources is 37% more economical than the command and control framework. Nevertheless, the cost saving may be reduced to ...

Joint occurrence of water quality indexes in relation to river streamflow in the heavily polluted Huai River Basin, China
Effective joint management of water quantity and quality of rivers requires a good understanding of the interrelationships between these variables. This study aims to quantitatively evaluate the impact of river streamflow on the joint occurrence of water quality variables in the heavily polluted Huai River Basin (HRB). Using data from three representative stations, joint distributions were ...

Water quality management in the context of future climate and development changes: a South African case study
Globally, water resources are being over-utilised; a situation exacerbated by degenerating water quality of rivers. To achieve sustainable management of water resources, uncertainty under climate change and development must be considered. A companion study was the first to incorporate uncertainty within water resources development scenario modelling for a catchment in South Africa using the ...

Toxicity Identification Evaluation (TIE) as a Tool for Water Quality Management
Whole effluent toxicity (WET) testing has evolved into a critical element of many National Pollutant Discharge Elimination System (NPDES) permits issued to both industrial and municipal dischargers. Over 6,500 dischargers to both fresh and salt waters are required to conduct toxicity tests to determine if their effluent might be potentially toxic to organisms in the receiving system. While ...

Real-time control of combined surface water quantity and quality: polder flushing
In open water systems, keeping both water depths and water quality at specified values is critical for maintaining a ‘healthy’ water system. Many systems still require manual operation, at least for water quality management. When applying real-time control, both quantity and quality standards need to be met. In this paper, an artificial polder flushing case is studied. Model Predictive Control ...

A review on interaction of groundwater and surface water
Interactions between groundwater and surface water play a fundamental role in water resources management. The movement of water between groundwater and surface water should be investigated in view of both quantity and quality aspects of water resources. In this paper, an attempt is made to define the primary concepts of this interaction and to illustrate a case study undertaken in ...
