Developing an online Water Quality Index (WQI) Report Card for the Ganga River in Uttar Pradesh, India S4: Water and Health: Managing Water Quality C.J. O’Neill – Director and Water Resource Engineer Water resource management, numerical modelling, DSS and Stakeholder Engagement
Environmental Report Card Synthesise large datasets for multiple sites Transformative assessment and communication tools Compare environmental data to scientific, legislative or management norms
Water Quality Index (WQI) Single number to express overall water quality based on range of biological, physical or chemical parameters Complex > Easy to Use Geo-spatial and spatio-temporal consolidation
Why
New Risks in the Digital Age? Reputation: Negative Public Image Public Perception: Too slow to react & Media response unclear Ecological Risk: Terrestrial and aquatic flora and fauna Human Health: Community health, productivity, ongoing illness Financial Risk: Rapid Response? Financial Risk: CAPEX AND OPEX waste Aim is to provide best available tools for management of water resources Here need to talk about the four key services that HN Performs
