Emerging Compounds in Drinking Water and NSF Standards
“NSF/ANSI 401: Emerging Compounds
NSF/ANSI 401 addresses the ability of a water treatment device to remove up to 15 individual contaminants (listed below), which have been identified in published studies as occurring in drinking water. While not a public health issue, the contaminants covered in NSF/ANSI 401 have been detected in drinking water supplies at trace levels and can affect some consumers’ perception of drinking water quality. (NSF/ANSI 401 also applies to reverse osmosis (RO) water treatment.)
- Meprobamate: a compound found in anti-anxiety drugs.
- Phenytoin: an anti-epileptic drug.
- Atenolol: a beta blocker drug.
- Carbamazepine: an anti-convulsant and mood-stabilizing drug.
- Trimethoprim: an antibiotic medication.
- Estrone: a prescription birth control drug.
Over-the-Counter Medications
- Ibuprofen: an over-the-counter pain reliever and anti-inflammatory medication.
- Naproxen: an over-the-counter pain reliever and anti-inflammatory medication.
- DEET (N,N-Diethyl-meta-toluamide): a pesticide and common active ingredient in insect repellents.
- 401: an organic compound that is widely used as an herbicide.
- Linuron: an herbicide often used in the control of grasses and weeds.
Chemical Compounds
- TCEP (Tris(2-chloroethyl)phosphate): a chemical compound used as a flame retardant, plasticizer and viscosity regulator in various types of polymers including polyurethanes, polyester resins and polyacrylates.
- TCPP (Tris(1-chloro-2-propyl) phosphate): a chemical compound used as a flame retardant.
- BPA (Bisphenol A): a chemical compound used as a plasticizer.
- Nonyl phenol: a collection of compounds often used as a precursor to commercial detergents.”
