AI in Water Management Quiz

Answers and explanations appear as you take the quiz.

1. In the cited AI leak-detection study, what input did the system analyze?
   • Acoustic recordings of water-pipe leak sounds
   • Household water bills alone
   • Street photographs without sound or pressure data
   • Social-media posts about wet roads
2. According to EPA, what can non-revenue water include?
   • Only water physically leaking from a pipe
   • Real losses, apparent losses, and authorized consumption that is not billed
   • Only treated water lost to evaporation
   • Only inaccurate customer bills
3. What objective does the cited pump-scheduling study use?
   • Maximize chemical dosing regardless of water quality
   • Eliminate all storage tanks
   • Minimize pumping-energy cost subject to water-system operating constraints
   • Replace the network with a digital map
4. In the cited treatment study, what did machine-learning models predict?
   • Ownership of distribution pipes
   • Satellite position over reservoirs
   • Customer bills from social-media posts
   • Chemical dosage from water-quality and streamflow inputs
5. What can EPA’s EPANET software simulate in a distribution network?
   • Pipe flows, node pressures, tank levels and chemical concentrations
   • Only rainfall over agricultural fields
   • Only billing and payment activity
   • Only treatment-plant staffing schedules
6. What does the cited satellite-data study predict for agricultural water-use support?
   • Household water-meter identity
   • Soil-moisture content using satellite imagery, ground truth and climate records
   • Location of every city pipe leak
   • Chlorine residual at each treatment plant
7. Which inputs did the cited water-demand forecasting study use?
   • Only treatment-plant photographs
   • Only water chemistry from one hour
   • Demand history, calendar variables and external weather features
   • Audio from customer-service calls
8. What agricultural goal does the satellite soil-moisture study say its predictions could support?
   • Choosing which customers pay higher tariffs
   • Finding chemical contaminants in pipes
   • Planning a Mars rover route
   • Improving water-use efficiency and reducing dependence on irrigation
