The City

The Cauca River is the drinking water source for 1.3 million inhabitants of the city of Cali, Colombia. Although the river discharge is sufficient to handle the water demand of the city all year long, significant water pollution events cause frequent disruption to the Puerto Mallarino Treatment Plant (PMTP) and the water supply service, with substantial social and economic impacts on the city. The sources of pollution include wastewater discharges upstream of the PMTP and important sediment transport from the upstream sub-catchments during heavy rainfall events. Both situations can lead to a closure of the PMTP when the presence of a pollution plume at its intake is evident. This paper presents the design and prototype of a water quality early warning system to anticipate the peaks of pollution in the river, in order to assist the operators in taking timely informed decisions about the operation of the treatment plant. As the published experiences of early warning systems for similar water pollution problems are very limited, the approach to solve the problem using hydroinformatics technologies is worth documenting for utility companies with a similar problem.

There is a serious problem of rural unsafe drinking water in china,but only it is essential for legislation to solve comprehensively.Through the analysis of the legislative background, legislative basis and legislative framework system of rural safe drinking water,the paper explores some legislative issues.Water source contaminated by industrial pollutants, agricultural pollutants, domestic pollutants, is the biggest obstacle to rural drinking water safety.Rural safe drinking water legislation have sufficiently the constitutional basis and the basic law basis. Legislative framework system is composed of drinking water source protection,rural water supply planning,project financing,operation and management mechanisms,emergency warning system, pricing system, supervision system etc. Rural safe drinking water legislation will play a significant role in solving fundamentally the problem of rural safe drinking water.

Drinking water supply safety is of paramount importance for human health. Disinfection is considered as one of the most significant water treatment processes as it inactivates pathogens from drinking water. However, disinfection might have adverse effects in human health, as disinfection by-products, blamed for cancer and reproductive/developmental effects, are formed. Many predictive models and optimization tools are developed in the research. However, an early warning system integrating monitoring, modelling and optimization tools is lacking. The paper reviews the disinfection methods and the models developed so far and presents the basic principles for the development of an early warning system.

This study assesses the suitability of the behavioural image analysis systems ECOTOX and Daphnia Tox for inclusion in an integrated early-warning system for drinking water quality to be implemented in Canada. Results of behavioural parameters measured by ECOTOX using Euglena gracilis are compared to visual observations of E. gracilis behaviour after exposure to atrazine, tributyltin, and copper to determine the automated system's sensitivity. The usability of the Daphnia Tox automated system is assessed using the aquatic macroinvertebrate species Daphnia magna and Hyalella azteca. The possible use of the rotifers Brachionus calyciflorus and Brachionus havanensis with the ECOTOX system is also assessed. Findings indicate that at the present state ECOTOX and DaphniaTox are not suitable for inclusion in an early-warning system, but based on visual observation the parameters measured are sensitive to the contaminants tested and consistent, and with suggested modifications these systems have the potential to be fitting additions in an early-warning system.

AbstractDrinking water supplies of cities are exposed to potential contamination arising from land use and other anthropogenic activities in local and distal source watersheds. Because water quality sampling surveys are often piecemeal, regionally inconsistent, and incomplete with respect to unregulated contaminants, the United States lacks a detailed comparison of potential source water contamination across all of its large cities. Here we combine national-scale geospatial datasets with hydrologic simulations to compute two metrics representing potential contamination of water supplies from point and nonpoint sources for over a hundred U.S. cities. We reveal enormous diversity in anthropogenic activities across watersheds with corresponding disparities in the potential contamination of drinking water supplies to cities. Approximately 5% of large cities rely on water that is composed primarily of runoff from non-pristine lands (e.g., agriculture, residential, industrial), while four-fifths of all large cities that withdraw surface water are exposed to treated wastewater in their supplies.
