Jim Dobbin – 2014 Parliamentary Question to the Department for Environment, Food and Rural Affairs

The below Parliamentary question was asked by Jim Dobbin on 2014-06-17.

To ask the Secretary of State for Environment, Food and Rural Affairs, with reference to the Answer of 196584 6 May 2014, Official Report, column 41W, on drinking water, what plans his Department has to test for the levels of tranquillisers and antidepressants in drinking water; and if his Department will conduct a study into levels of psychotropic drugs in UK river and seawater.

In 2012, the Drinking Water Inspectorate (DWI) published research looking at pharmaceuticals likely to present the worst case scenario in drinking water. Fluoxetine was included in the study, the outcome of which was that these pharmaceuticals presented no concern for public health. The research is part of an ongoing risk assessment which is revisited in the event of new information. The DWI has also responded to the earlier PQ (0019) on this matter.

Monitoring river water and seawater is driven by requirements under the EU Water Framework Directive (WFD). As psychotropic drugshave not been identified as harmful chemicals under the WFD they are not routinely monitored, although they may be detected in less-specific investigations.

The water industry has undertaken collaborative research into chemicals in sewage effluent through the UK Water Industry Research (UKWIR) Chemicals Investigation Programme. Some medicines were included in the first Programme of 2010-13, including fluoxetine. A second Chemical Investigations Programme, beginning in 2015, will look at the psychoactive medicines fluoxetine and sertraline in sewage effluent.
