Top 11 Compounds in Tap Water

New Scientist provides a list of the top 11 compounds found in a tap water analysis of 19 US water utilities conducted by researchers at the Southern Nevada Water Authority. According to the EPA, there is no cause for alarm although there could be risk “especially for the fetus and those with severely compromised health.”

The eleven compounds – all found at extremely low concentrations – are:

  • Atenolol, a beta-blocker used to treat cardiovascular disease
  • Atrazine, an organic herbicide banned in the European Union, but still used in the US, which has been implicated in the decline of fish stocks and in changes in animal behaviour
  • Carbamazepine, a mood-stabilising drug used to treat bipolar disorder, amongst other things
  • Estrone, an oestrogen hormone secreted by the ovaries and blamed for causing gender-bending changes in fish
  • Gemfibrozil, an anti-cholesterol drug
  • Meprobamate, a tranquiliser widely used in psychiatric treatment
  • Naproxen, a painkiller and anti-inflammatory linked to increases in asthma incidence
  • Phenytoin, an anticonvulsant that has been used to treat epilepsy
  • Sulfamethoxazole, an antibiotic used against the Streptococcus bacteria, which is responsible for tonsillitis and other diseases
  • TCEP, a reducing agent used in molecular biology
  • Trimethoprim, another antibiotic
