Legionella prosecutions & fines, with a fines-by-year chart
New /legionnaires-disease-prosecutions page: 30 source-verified UK enforcement cases (2005-2024), how the courts sentence Legionella failings, and an interactive fines-by-year chart whose dots link to each case.
UK Legionnaires’ disease case data, charted
New /legionnaires-disease-cases page charting confirmed cases across the UK, 2011-2024, from UKHSA (England & Wales), Public Health Scotland and the PHA in Northern Ireland, with exposure categories, deaths and sources.
Cluster hubs, knowledge checks and a regulatory timeline
Added dedicated hubs for cooling towers, healthcare (HTM 04-01), international standards and field procedures; self-assessment quizzes; and this updates log plus a regulatory timeline.
Coverage expanded: cooling towers, clinical and international
New articles on cooling-tower water chemistry and control, the clinical course of Legionnaires’ disease, international standards, and field method-statements.
Canonical control-parameters reference + interactive system explorer
A single cited home for the control figures (/reference) and a clickable water-system explorer (/system) mapping risk, rule and check to each component.
Standards library: editions and clause references
Each standard now has its own page with edition, key references and a "last checked" date, so the reference is defensible and citable.
Privacy-first analytics and accessibility fixes
Analytics moved behind a deny-by-default consent banner; contrast and other accessibility issues addressed.
