  2. Drinking water quality standards - Wikipedia

    en.wikipedia.org/wiki/Drinking_water_quality...

    Drinking water quality standards describes the quality parameters set for drinking water. Water may contain many harmful constituents, yet there are no universally recognized and accepted international standards for drinking water. Even where standards do exist, the permitted concentration of individual constituents may vary by as much as ten ...

  3. Nitrate - Wikipedia

    en.wikipedia.org/wiki/Nitrate

    Through the Safe Drinking Water Act, the United States Environmental Protection Agency has set a maximum contaminant level of 10 mg/L or 10 ppm of nitrate in drinking water. [ 20 ] An acceptable daily intake (ADI) for nitrate ions was established in the range of 0–3.7 mg (kg body weight) −1 day −1 by the Joint FAO/WHO Expert Committee on ...

  4. Nitrate test - Wikipedia

    en.wikipedia.org/wiki/Nitrate_test

    Testing for the presence of nitrate via wet chemistry is generally difficult compared with testing for other anions, as almost all nitrates are soluble in water. In contrast, many common ions give insoluble salts, e.g. halides precipitate with silver, and sulfate precipitate with barium. The nitrate anion is an oxidizer, and many tests for the ...

  5. Maximum contaminant level - Wikipedia

    en.wikipedia.org/wiki/Maximum_Contaminant_Level

    Maximum contaminant levels (MCLs) are standards that are set by the United States Environmental Protection Agency (EPA) for drinking water quality. [1] [2] An MCL is the legal threshold limit on the amount of a substance that is allowed in public water systems under the Safe Drinking Water Act (SDWA).

  6. Drinking water quality in the United States - Wikipedia

    Fluoride pollution from various industrial emissions can also contaminate water supplies. In a few areas of the United States, fluoride concentrations in water are much higher than normal, mostly from natural sources. In 1986, EPA established a maximum allowable concentration for fluoride in drinking water of 4 milligrams per liter (mg/L).

  7. Methemoglobinemia - Wikipedia

    en.wikipedia.org/wiki/Methemoglobinemia

    Nitrates used in agricultural fertilizers may leak into the ground and may contaminate well water. The current EPA standard of 10 ppm nitrate-nitrogen for drinking water is specifically set to protect infants. [13] Benzocaine applied to the gums or throat (as commonly used in baby teething gels, or sore throat lozenges) can cause methemoglobinemia.
