Gathering the latest records.
One observation.
A shared next step.
Turn local observations into a coordinated investigation. Different people. Clear steps. A clearer picture.

Different skills.
A common purpose.
Observers, monitors and experts each do the part they are qualified for, and every decision stays connected to its evidence.
Notice & contribute
Describe what you observed, when, and where. A photo is welcome but optional. A coordinator reviews the report and connects it to a local investigation.
Coordinate & collect
Coordinators check what is known and organize feasible work. Qualified monitors collect traceable measurements with the right instruments and protocols.
Review & revise
Qualified reviewers evaluate evidence and assumptions. Decisions remain connected to their records, and can change when new evidence arrives.
Evidence first.
Uncertainty visible.
A photo can document a change. It cannot identify a pollutant or establish water safety.
What a reading can say
Conductivity alone does not identify a chemical or prove a source. Source-area analysis needs a reviewed network, comparable measurements and explicit uncertainty bounds. When those are missing, the investigation stays open and the next step is to build that foundation.
What a result means
A reach that remains under consideration is not proven responsible. An excluded reach is incompatible under stated assumptions, not proven free of impact. New evidence can expand the area under consideration.

Stay on safe, permitted access routes. Do not enter the water or approach a suspected hazard to make a report. For an immediate threat, contact the appropriate local emergency service.
