Questions about Tees Coastal

Which outlets are linked to Tees Coastal?
The source links 32 outlet records to waterbody GB650301500005. The link comes from the annual return; it does not model where a discharge travelled.
How many spills were recorded for Tees Coastal?
32 records report 401 spills in 2025 and 1,620 recorded hours. All listed records have a usable count. Outlets can discharge at the same time, so the hours are not the time the whole water was affected.
Who is responsible for the outlets on Tees Coastal?
Northumbrian Water operates every listed outlet. Contact the operator or the official pollution service if you see a problem in the water.
Which outlets on Tees Coastal are linked to a live feed?
29 of the 32 records are matched to a monitor in a company live feed. A link does not mean the monitor is working now. Use the status filters above to see the latest report for each outlet, with its date. The rest show annual figures only.
How complete is the monitoring for Tees Coastal?
5 of the listed records have monitor operation below 90% for 2025. Events can be missed when a monitor is not working, so low counts from those outlets may understate activity.
Does this show if Tees Coastal is safe?
No. Event duration data does not measure bacteria, chemicals or current water quality. Use official local water-quality advice for that question.
