EA name: AIRE AT SNAITH
Environment Agency sampling point NE-49400438 · Freshwater - rivers · listed as open (“open” does not mean it is sampled now)

Everything measured here
25 determinands, each kept by its code, unit and sample material: results in different units or on different materials are never mixed. A “below” result is under the laboratory's detection limit, not zero.

FloodRadar does not grade these results: there is no overall score, and official river classifications are a separate dataset. A sample taken downstream of an overflow does not by itself show where anything in it came from. River connections and distances are traced on OS Open Rivers (edition 2026-04), which leaves out many small channels.
