Water quality monitoring stations across the West
Monitoring stations that tell you whether the water is usable, not just available.
Having water and being able to use it are different questions. Water quality monitoring answers the second one: a supply that needs treatment before it can cool a building or irrigate a field carries a capital cost that never appears on the water right itself.

Why Water Quality Stations matters
Water that needs treatment is a different asset than water that does not, and the delta shows up as capital cost, operating cost and permit conditions. For industrial and cooling loads in particular, salinity and mineral content decide the entire water treatment design.
Questions Water Quality Stations answers
- Is the water at this intake usable for cooling without pre-treatment?
- Is there a salinity or metals trend upstream of my diversion?
- Which stations near this site have a long enough record to underwrite against?
What is in the Water Quality Stations data
Coverage: Western US monitoring network. Source dataset: Water quality monitoring station network.
| Field | What it tells you |
|---|---|
| Station identifier | Monitoring location ID, citable in a report or permit application. |
| Parameters sampled | Which constituents the station measures — salinity, metals, nutrients, temperature and others. |
| Sampling organization | The agency or program responsible for the station. |
| Period of record | How far back the station's history runs, which determines whether a trend is meaningful. |
How we serve Water Quality Stations
Stations are served from the layer API as GeoJSON with a bbox filter and an in-memory cache; if the upstream service fails we return an empty collection rather than break the map, and the layer's data-currency badge shows when it last refreshed successfully.
