EQ: How can we determine the safety and drinkability of our water supplies?

LT: I can describe the processes that can be used to convert unusable water to usable resources.

LT: I will make observations about rock type vs. permeability I will draw and label the steps for water filtration I will work with my group to review water filtration concepts. Warm Up Intro to Water Filtration Build Water Filter

Welcome! Warm Up 3/20/14

Water Treatment Video

Water Filtration Vocabulary 24 Runoff – is precipitation that flows over land into streams and

rivers. This water later enters oceans.Filtration – process of passing water through a series of

screens that allow water through but not large particlesAeration – The water is mixed to release dissolved gases and

to suspended particles in water column.Coagulation – The process by which particles in a liquid

clump together Sedimentation – The water left undisturbed to allow the

heavy clumps of particles and coagulants to settle out Disinfection – The water is treated to destroy any remaining

disease causing pathogens Potable Water – water safe enough to drink by humans
