7. Effective = Reverse Osmosis, Distillation / Ineffective = Ultraviolet Radiation, Microfiltration

Answer 8

Kieran is working is run his dishwasher
Reverse osmosis and distillation is effective and ultraviolet abs micro filtration is ineffective
Wastewater from which source is kitchen sink
Clean water is wastewater management and surface water quality and safe drinking water is groundwater contamination and surface water quality
In average households toilets use the most water
Lead exposure causes development delays in children
And the ladder looking one with the red base and the sewage drain pics are point source while the pollution ones are nonpoint
