Water
is refreshing, hydrating, and invaluable to your survival. But clean
water remains a precious and often scarce commodity – there are nearly
800 million people who still don’t have regular access to it. Why is
that? And how can you tell whether the water you have access to —
whether from a tap or otherwise — is drinkable? Mia Nacamulli examines
water contamination and treatment.
