The EA’s area boundaries do not align exactly with water company catchments. This will mean that a small number of incidents will not be included in this analysis.

The use of “other polluting discharges” the EA have taken to mean all other types of pollution incidents into water.

Finally, the EA have included pollution incidents to all types of waterbodies including coastal waters and rivers.

For Part B and C of this question, we do not hold that information, the respective organisations would be best placed to answer.

I would also refer the hon. Member to the Written Statement made by the Secretary of State on 18 July: Written statements - Written questions, answers and statements - UK Parliament.
