How we work this out
Concern combines hazard — warning signs in residents' reports from the last 30 days, weighted by each observer's trust and each report's quality — with exposure: playgrounds, schools, parks, bathing and fishing spots and allotments from OpenStreetMap within 150 m. A sign is possible from 20% of reports and likely from 50% reported by at least 2 different people. All of these thresholds are uncalibrated priors.
This is an early prompt to take care, based on what people can see and smell. It is not a medical or public health assessment and not an official bathing-water classification — follow your local health and environment authorities.
