  2. Water testing - Wikipedia

    en.wikipedia.org/wiki/Water_testing

    Water testing being conducted at a treatment facility in Broken Bow, Oklahoma. Water testing is a broad description for various procedures used to analyze water quality. Millions of water quality tests are carried out daily to fulfill regulatory requirements and to maintain safety. [1] Testing may be performed to evaluate:

  3. Radium - Wikipedia

    en.wikipedia.org/wiki/Radium

    The great insolubility of radium sulfate (at 20 °C, only 2.1 mg will dissolve in 1 kg of water) means that it is one of the less biologically dangerous radium compounds. [27] The large ionic radius of Ra 2+ (148 pm) results in weak ability to form coordination complexes and poor extraction of radium from aqueous solutions when not at high pH.

  4. Radithor - Wikipedia

    en.wikipedia.org/wiki/Radithor

    It consisted of triple-distilled water containing at a minimum 1 microcurie (37 kBq) each of the radium-226 and 228 isotopes. The time of Radithor and radioactive elixirs ended in 1932, with the premature death of one of its most fervent users, Eben Byers, an American golfer. This history led to the strengthening of regulatory control of ...

    These chemicals included radium-226, radium-228, arsenic and lead. The two radium isotopes are commonly found around uranium deposits and are hazardous to human health, even in small quantities. 2.

  6. Radium and radon in the environment - Wikipedia

    en.wikipedia.org/wiki/Radium_and_radon_in_the...

    Radium, like radon, is radioactive and is found in small quantities in nature and is hazardous to life if radiation exceeds 20-50 mSv/year. Radium is a decay product of uranium and thorium. [2] Radium may also be released into the environment by human activity: for example, in improperly discarded products painted with radioluminescent paint.

  7. 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 ...

  8. Solubility table - Wikipedia

    en.wikipedia.org/wiki/Solubility_table

    The tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams of substance per 100 millilitres of water (g/(100 mL)), unless shown otherwise. The substances are listed in alphabetical order.

  9. Bacteriological water analysis - Wikipedia

    en.wikipedia.org/wiki/Bacteriological_water_analysis

    Bacteriological water analysis is a method of analysing water to estimate the numbers of bacteria present and, if needed, to find out what sort of bacteria they are. It represents one aspect of water quality. It is a microbiological analytical procedure which uses samples of water and from these samples determines the concentration of bacteria ...
