Water quality in the Dawu water source area is primarily studied through traditional assessment method that measures chemical parameters of against existing standards, which simple but cannot accurately describe quality. Although index (WQI) proposed by Horton widely used for comprehensive evaluation, parameter selection and weight determination are based on Delphi method, subjective random. Mo...

Aggregative data infrastructures (ADIs) are information systems where organizations can find the tools to integrate their data sources to form uniform and richer information spaces of object metadata descriptions. Novel sustainable approaches for the realization of ADIs are based on the adoption of ADI enabling technologies which support the realization, maintenance and upgrade of ADIs and prom...

Coal mine generated open pit lakes are well distributed in Raniganj coal field area, West Bengal, India. This paper screened out ecological state macrophyte index (ESMI), water quality (WQI) and multivariate statistical methods to assess the status of four lakes, Nagrakonda, Joyalbhanga, Dalurbandh, Kumardihi. Seven parameters (pH, total dissolved solids, oxygen, Secchi depth nitrate, chloride,...

The operationalization of water resource protection initiatives for surface quality and equitable allocation is critical sustainable socio-economic development. This paper assessed Blesbokspruit River Catchment’s status, using the South African Water Quality standards Index (WQI). Protection levels quality, waste discharge point sources were set evaluated total maximum daily loads (TMDLs) chemi...

In this research, spatial – temporal variations of water quality in the fluvial components Hasana?a Stream Basin were evaluated by using Water Quality Index. Surface samples taken from seven stations selected on basin winter seasons 2019 and 2020. Eleven variables including dissolved oxygen, oxygen saturation, pH, electrical conductivity, total solids, salinity, turbidity, nitrate, nitrite, pho...

Background: Contamination of groundwater could result in serious and irreparable health problems for consumers. This study assessed the water quality human implications metals packaged from Abeokuta Sagamu, southwestern Nigeria. Methods: One hundred forty bags were purchased analyzed physical chemical parameters using standard procedures, while determined inductively coupled plasma optical emis...

Urban river not only has the important function in urban hydrological environment, but also is an area for entertainment. Water quality assessment core technique water resource management. As typical river, samples were collected at 5 sampling points Xi’an moat from January 2018 to December 2020, and 10 physicochemical parameters analyzed. In this paper, a comprehensive index (WQI) designed bas...
