01 / THE BLUEPRINT
The problem to investigate
A community may notice unusual taste, colour or smell yet not know who can officially test a source or what response is required. Rumours can spread faster than authorised guidance.
02 / THE BLUEPRINT
A possible solution
Build a directory of legitimate sampling contacts and public reporting instructions, with a non-public case queue for approved water officers. Explain that appearance alone cannot determine microbiological or chemical safety.
03 / THE BLUEPRINT
Start without an app
A clearly posted laboratory contact list and incident telephone tree may be safer and simpler than an app collecting public accusations.
04 / THE BLUEPRINT
Technology that could help
Use a manually verified directory, role-based complaint triage and status categories that never interpret raw tests automatically. Public notices should come from the responsible authority.
05 / THE BLUEPRINT
Your first experiment
- Ask the local water authority to define reporting and sampling roles.
- Verify three laboratories or authorised officers and their contact procedures.
- Test a fictitious water-quality complaint end to end.
- Review privacy, urgent escalation and source labelling before real submissions.

People, resources and cost drivers
Requires trained water-quality personnel, sampling capacity and transport to laboratories. Funds are needed for actual tests and response, not only a website.

07 / THE BLUEPRINT
What to validate — and when to stop
Check whether alerts reach somebody authorised to act and whether public messaging is scientifically reviewed. Stop if unresolved reports are incorrectly shown as safe.
08 / HYPOTHESIS TO TEST
Potential impact and how to measure it
Measure time to authoritative guidance, completed sample referrals and corrected directory entries. Do not claim fewer illnesses without independent public-health research.
09 / THE BLUEPRINT
Risks and safeguards
Incorrect reassurance or false contamination allegations can harm health and livelihoods. Keep private case records protected and obtain expert sign-off for any safety statement.
10 / THE BLUEPRINT
Who might pay or maintain it
A responsible utility or public-health programme must own response procedures; a civic group may maintain contact accuracy but not assume legal testing authority.
