34.Ground Water 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 describe groundwater. I will determine which type of soil is most permeable to water. I will explain why groundwater is becoming a non- renewable resource.

Groundwater Notes 23 Groundwater – water that soaks in the ground & collects in rocky pores (pores – space between rocks) Permeable – allows water to flow easily through (ex: sandstone) Impermeable – Doesn’t allow water to move through b/c of small, few or no pores (ex: clay) Aquifer – layer of permeable rock that lets water move freely

NB 23: Groundwater

How does groundwater travel? Interconnecting pores How do you replace groundwater? Time and precipitation Why is groundwater becoming a non-renewable resource? We are using it up faster than nature can replace it. (Avg. person use 397 Liters per day) Also pollution NB 23

Finish the conclusion questions for the lab

EXIT: I. How did you observe permeability in today’s activity? II. Use Impermeable in a sentence
