  3. Wastewater-based epidemiology - Wikipedia

    en.wikipedia.org/wiki/Wastewater-based_epidemiology

    Wastewater-based epidemiology has been used to estimate illicit drug use in communities or populations, but can be used to measure the consumption of alcohol, caffeine, various pharmaceuticals and other compounds. [2] Wastewater-based epidemiology has also been adapted to measure the load of pathogens such as SARS-CoV-2 in a community. [3]

  4. Wastewater quality indicators - Wikipedia

    en.wikipedia.org/wiki/Wastewater_quality_indicators

    Wastewater quality indicators are laboratory test methodologies to assess suitability of wastewater for disposal, treatment or reuse. The main parameters in sewage that are measured to assess the sewage strength or quality as well as treatment options include: solids, indicators of organic matter, nitrogen, phosphorus, indicators of fecal ...

  5. MBAS assay - Wikipedia

    en.wikipedia.org/wiki/MBAS_assay

    A methylene blue active substances assay, or MBAS assay, is a colorimetric analysis test method that uses methylene blue to detect the presence of anionic surfactants (such as a detergent or foaming agent) in a sample of water. An anionic surfactant detected by the color reaction is called a methylene blue active substance (MBAS). [1]

  6. Analysis of water chemistry - Wikipedia

    en.wikipedia.org/wiki/Analysis_of_water_chemistry

    Water chemistry analysis is often the groundwork of studies of water quality, pollution, hydrology and geothermal waters. Analytical methods routinely used can detect and measure all the natural elements and their inorganic compounds and a very wide range of organic chemical species using methods such as gas chromatography and mass spectrometry.

  7. Wastewater surveillance - Wikipedia

    en.wikipedia.org/wiki/Wastewater_surveillance

    Wastewater surveillance is the process of monitoring wastewater for contaminants. Amongst other uses, it can be used for biosurveillance , to detect the presence of pathogens in local populations, [ 1 ] and to detect the presence of psychoactive drugs .

  8. Water testing - Wikipedia

    en.wikipedia.org/wiki/Water_testing

    Wastewater analysis. All facilities in the United States that discharge wastewater to surface waters (e.g. rivers, lakes or coastal waters) must obtain a permit under the National Pollutant Discharge Elimination System, a Clean Water Act program administered by EPA and state agencies. The facilities covered include sewage treatment plants ...

  9. Total suspended solids - Wikipedia

    en.wikipedia.org/wiki/Total_suspended_solids

    Total dissolved solids is another parameter acquired through a separate analysis which is also used to determine water quality based on the total substances that are fully dissolved within the water, rather than undissolved suspended particles. TSS is also referred to using the terms total suspended matter (TSM) and suspended particulate matter ...
