Quality Measurements

The paper describes the results of measurements from a 2 year period on a 95 hectare urban catchment in Aalborg, Denmark. The results of the rain/discharge measurements include 160 storm events corresponding to an accumulated rain depth of totally 753 mm. The water quality measurements include 15 events with time series of concentration of SS, COD, BOD, total nitrogen and total phosphorus. The quality parameters showed significant first flush effects. The paper discusses whether either the event average concentration or the accumulated event mass is the most appropriate way to characterize the quality of the outflow.

Method Approach

The industrial sector is one of the important sector in supporting the development of a region. Utilization of land around the river that is used for industrial activities will affect the quality of river water. The river can be polluted by waste personinating from industries that operating around the river. The catchment area that used for industry, agriculture, urban development, and the use of land for making roads (gravel or footpaths) can affect the flow of surface water and sediments that it brings to the river. Waste generated from industrial activities can pollute rivers which are a source of water for daily needs and affect the development of biota in them. This can affect river water quality

AbstractThis paper evaluates water quality and ecological status of lakes located in the Wielkopolska National Park and its buffer zone. Changes in water quality were analyzed from 1974 to 2012 in order to assess the effectiveness of the protection strategies implemented on the studied lakes since 1957, i.e. the date when the park was established. The ecological status of the lakes was assessed with the use of macrophytes as well as hydromorphological and physicochemical analyses performed in 2012. Changes in water quality of the studied lakes within the last 40 years were analyzed based on available published and unpublished data, as well as field studies. All water bodies are characterized by advanced eutrophication. However, evaluation of the ecological status showed good status of the charophyte-dominated lakes, i.e. Lake Wielkowiejskie and Lake Budzyńskie. Lack of significant differences in physicochemical water qualities between the park and its buffer zone indicated that measures implemented to protect the water, particularly in the park, are ineffective. This study shows that more radical conservation measures are necessary to protect and improve the water quality, not only in WPN and its buffer zone but also in the whole catchment area.

In this study the water quality of Teluk Lake, Jambi Province by biological indices using macroobenthic during December 2017 to March 2018 were evaluated. Macro obenthic have been the most commonly indicator of running water quality to rapidly detect water quality changes. The methodology consisted on three stages: 1) macro invertebrates sampling and and sorting of the organisms in laboratory, 2) taxonomic identification of organisms and 3) determination and scoring with the Biological Monitoring Working Party -Average Score per Taxon (BMWP-ASPT) index. Result of water quality of Teluk Lake based on the diversity of macroinvertebrates was degraded with BMWP-ASPT index below 4. Based on the BMWP-ASPT score of the macroinvertebrates, both of sampling 1 and 2 were polluted with the category of medium and heavily polluted. In general, the decreasing of water quality of Teluk Lake was due to anthropogenic activities, so that the intolerant macro invertebrates could not survive in polluted waters while the tolerant ones can adapt well to the polluted aquatic environment.

The results of studies of sea and river waters, soils of the territory adjacent to the Vanino transport and industrial hub are presented. Iron, manganese, copper and zinc have been identified as common priority pollutants of sea and river water. The quality of river waters of the Toki and Aya rivers, estimated by 14 hydrochemical indicators, is classified as "polluted". Local areas of peat-bog soil and brown soils belonging to the Toki river catchment area were identified as background areas in the studied territory.

Abstract One of seventeen points of Sustainable Development Goals (SDGs) is to provide clean water for at least 80% of the global population in 2025. Rural populations living surrounding Lake Toba water catchment area still utilize the lake water for daily use regardless of the susceptible decreasing water quality. This paper describes anthropogenic aspects affecting the water quality of Lake Toba that is consumed as the drinking water source by surrounding residents. The research used a quantitative approach by interviewing 130 household representatives from 3 regencies around the lake to calculate the water consumption and evaluate the water quality in 2018. In addition, this research also assessed the residents' behavior in managing household waste and wastewater. The result showed that the average water consumption is 86,93L/person/day. The majority of the respondents barely treat the water and feel satisfied with the water quality based on its color, turbidity, taste, and odor. On the contrary, the respondents have not adequately treated their domestic waste and household wastewater before being released to the lake, contributing to water pollution. Although most respondents are satisfied with the water quality, it is still needed to perform proper water treatment because the water quality of Lake Toba is reported as slightly up to heavily polluted by the Ministry of Environment and Forestry in 2019.
