Abstract A summary of selected Canadian experiences in the application of biological tests for controlling and monitoring effluent quality, for setting water quality objectives, and for monitoring receiving waters is presented. ? brief review is made of the approaches for applying biological tests to effluents, to the selection of suitable water quality objectives, and to the conduct of ambient biomonitoring programs. Two case examples from Canada, the Saint John River, New Brunswick, and Canagagigue Creek, Ontario, are evaluated in detail. A number of other Canadian sites where biological tests are being applied are also discussed. The contributions of biological tests on effluents to administrative decisions for pollution control, as well as the limitations of solely using “end of pipe” tests, are emphasized in the paper.

Regional Specialisation

In Finland, the first large-scale efforts to control nutrient loading from agriculture got under way with the introduction of the EU Agri-Environmental Program in 1995. We examined whether these efforts have decreased agricultural nutrient losses and improved the quality of receiving waters. To do so we used monitoring data on fluxes of nutrients and total suspended solids in agricultural catchments in 1990–2004 and on the water quality of agriculturally loaded rivers, lakes and estuaries in 1990–2005. No clear reduction in loading or improvement in water quality was detected. Hydrological fluctuations do not seem to have eclipsed the effects of the measures taken, since there was no systematic pattern in runoff in the period studied. The apparent inefficiency of the measures taken may be due to the large nutrient reserves of the soil, which slowed down nutrient reductions within the period studied. Simultaneous changes in agricultural production (e.g. regional specialisation) and in climate may also have counteracted the effects of agri-environmental measures. The actions to reduce agricultural loading might have been more successful had they focused specifically on the areas and actions that contribute most to the current loading.;

The Catingueiro, Cristalino and Ligeiro Rivers, present in the eastern region of Cianorte, Paraná, Brazil, are under constant influence of industrial effluents and agrochemicals. In 2022, the public supply of this municipality will be made by waters of the Ligeiro River, and the sites predicted for abstraction are close to the sites of confluence of the Catingueiro River and the Cristalino River with the Ligeiro River. We evaluated in two periods of 2020, based on different parameters, the water quality of the Catingueiro River at two sites, P1 and P2 (P2, upstream of the confluence), the Cristalino River in one site, P3, and the Ligeiro River at two sites, P4 and P5 (P5, downstream of the confluence). Levels of nitrite, nitrate and sulfate in waters were within the range set by law. All points had a high concentration of fluorides and phosphato in the two collections. In P1, in both collections, a high concentration of copper was found.  P1 and P2, in the second collection, presented high levels of aluminum. Silicon was detected at all sites. Waters were phytotoxic to L. sativa and cytotoxic to the root meristems of A. cepa. Physical-chemical and toxicity analyses suggest a compromise in water quality. These data are an alert to the public authorities of Cianorte and Paraná regarding the anthropic actions carried out in these rivers and alert the sanitation company to carry out a preliminary and periodic analysis of the waters in order to know the contaminants present before treating them.

As a developing country, industrialization is rapidly growing up in Bangladesh. Most of the cases, the industrialization process don’t considering any impact on environmental body. In this study, the impact of unplanned industrialization on the surface water is the main focus. In between several resources, the water quality of the Sitalakhya River is our study area. Quality of the Sitalakhya River water is getting polluted day by day through industrial effluents and household wastewater, lube oil and oil spillage around the operation of river ports. The Sitalakhya river water quality analysis is considered between 1975 to 2018, qualitative and quantitative results for pH, DO and BOD were analyzed and also trends of these parameters were also analyzed. Day by day river water quality going far away from EQS value, which is significantly harmful to flora fauna. In this circumstance, industrial effluent and other environmental impacts from unplanned industrialization is main goal of this study. This study shows, how unplanned industrialization can damage an environmental system which is very harmful to our entire ecological cycle. If cannot control this unplanned industrialization, water body will damage and all related ecosystem will be effected.

AbstractThe Xiong'an New Area was established by the Chinese government on 1 April 2017 as a new district in the Hebei Province, and soon after its establishment, investigations on the waterbodies of the district began to initiate governance. In this study, data from 105 Sentinel-2 cloudless images for the period April 2016–September 2019 were analysed to understand the changes in the concentrations of chlorophyll-a and water turbidity in surface waterbodies of the Xiong'an New Area. The results suggest that (1) the water quality shows an overall improving trend owing to surface-water pollution control measures by the Chinese government in the region; (2) the turbidity of the surface waterbody declined gradually particularly after the spring of 2017; (3) the concentration of chlorophyll-a shows a weak decreasing trend, with a low value in spring and a high value in summer with a four-year average of 31.3 μg/L; and (4) by comparing the results of the water quality of two ponds inside and outside the Lake Baiyangdian and the overall water quality of Xiong'an New Area, the changes in turbidity and chlorophyll-a concentration during the study period were consistent.

This paper outlines the improvements in water quality which have occurred in the River Trent catchment since about 1960 and the strategies by which they have been achieved. During this period there have also been several major changes in the structure of water quality management, in pollution control legislation and in the use of river and effluent quality standards. The links between quality trends, legislation, management structures and investment in sewerage and sewage treatment are considered. Prospects for the future under the current management regime are discussed.

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 balance detailed monitoring at a limited number of locations versus less detailed monitoring at a large number of locations. This paper proposes a methodology for the selection of monitoring locations for storm water quality monitoring, based on (pre-)screening, a quick scan monitoring campaign, and final selection of locations and design of the monitoring setup. The main advantage of the method is the ability to prevent the selection of monitoring locations that turn out to be inappropriate. In addition, in this study, the quick scan resulted in a first useful dataset on storm water quality and a strong indication of illicit connections at one of the monitoring locations.
