Cheltenham Open Data Adds River Water Quality Readings

Chemical water quality readings for the River Chelt and nearby brooks, from the Environment Agency's Water Quality Archive.

Cheltenham Open Data has published a new river water quality page, showing the latest chemical readings for the River Chelt and nearby brooks.

The Environment Agency visits each sampling point roughly once a month, testing a batch of determinands — pH, water temperature, conductivity, nitrate, ammoniacal nitrogen and more — in one go. This page shows every reading from the most recent visit to each of the 7 open river sampling points within 5 miles of Cheltenham, on a map and in a sortable table.

This joins our flood warnings and sewage overflow status pages as the third part of our River Chelt data coverage — all three now link to each other.

FAQs

What Does This Page Show?

  • The latest chemical water quality readings (pH, temperature, nutrients and more) for each Environment Agency sampling point near Cheltenham, from that point’s most recent test visit.

Where Does the Data Come From?

Is This Live Data?

  • No — each sampling point is only tested periodically, roughly monthly. The “Sample Date” column shows when that specific point was last visited, which may be several weeks before the page’s own “last updated” date.

How Is This Different From the Sewage Overflow Page?

  • The sewage overflow page tracks discharge activity (is an overflow currently releasing wastewater) in near-real-time. This page tracks actual chemical water quality from lab-tested samples, refreshed much less often.
