Receptors
Animals as Environmental Receptors
Animals drink from the same water network, breathe the same air and live on the same ground — usually with far greater exposure than people. That makes them useful observers, provided their health is assessed by a vet and not by a website.
Groups
Which animals are relevant, and why
Pets
Dogs and cats often drink from streams, puddles and outdoor bowls, and share a household water supply with people.
Evidence needed · Veterinary records are the evidence.
Livestock
Cattle, sheep and horses consume large volumes of water daily from field troughs and natural sources, making them sensitive integrators of water quality.
Evidence needed · Farm records and veterinary reports.
Wild mammals
Badgers, foxes and deer use the landscape continuously and are exposed through water, soil and prey.
Evidence needed · Carcass reports; post-mortem where available.
Birds
Woodland and riparian birds are exposed through invertebrate prey, which concentrates some substances.
Evidence needed · Systematic recording, not anecdote.
Aquatic life
Fish and amphibians live continuously in the medium under investigation and cannot avoid it.
Evidence needed · Mortality events, with date and location.
Invertebrates
Stream invertebrate communities are the single most sensitive routine indicator of freshwater condition available.
Evidence needed · Standard biotic index surveys.

Why this is worth doing
Exposure without avoidance
A dairy cow may drink upwards of a hundred litres of water a day from a single field trough. A dog drinks from the stream it walks past. Neither can choose bottled water when something tastes wrong, and neither is subject to the reporting biases that affect human self-reporting.
Where a veterinary diagnosis and a water source coincide across several households on the same supply network, that is a specific, testable observation of exactly the kind this project exists to surface — and exactly the kind that requires professional laboratory work to interpret.
Evidence status
Animal health: where this stands
Concerns have been raised
Animal health concerns have been raised by people in the area. These are logged with whatever supporting evidence exists.
Any environmental cause
No animal health event in this area has been shown to have an environmental cause, and no such claim is made.
