To ask the Secretary of State for Wales what assessment he has made of pollution levels of rivers and streams in Wales in the last 12 months; and if he will make a statement.

Water quality of rivers and streams in Wales is regularly monitored by the National Rivers Authority and the results of samples obtained are recorded on public registers maintained by the authority. The authority publishes comprehensive river quality surveys every five years, and pollution incident reports annually, copies of which are placed in the Library of the House.
