Across
- 3. When saltwater along coastlines moves into aquifers if too many wells draw water from the ground
- 5. Groundwater zone where soil/ rock are not holding full amount of water and there are still air pockets
- 6. Cancer causing agents
- 9. Type of treatment where nutrients are removed from a secondary effluent so they can be released back to the source
- 10. An imaginary line that divides the saturated zone from the unsaturated zone and fluctuates based on precipitation amounts
- 12. Groundwater zone where all available spaces are filled with water
- 13. Area of land that collects/ funnels precipitation to a lake, stream, river, or other outlet
- 14. Cover 71% of earths surface and moderate earths temperature
- 16. Type of source pollution from a specific location
- 18. Contains less than 0.001% total water supply and distributes water evenly over landmasses and replenishes land reservoirs
- 19. Type of biological treatment of activated sludge to create a new, disinfected effluent
Down
- 1. Amount of water used for all purposes per person over a given time
- 2. Type of water with high biodiversity and productivity
- 4. Type of treatment where large solids are separated using screens and rakes
- 7. Type of water that is clear and has low biological productivity
- 8. Formed by glaciers and contain 20% of the worlds available surface water
- 11. A bloom of dinoflagellates that uses of 02 and produce toxin that kill organisms, caused by eutrophication
- 15. Area of permeable rock, gravel, or sand that holds water
- 17. Type of source pollution from no specific location of discharge or multiple sources
- 19. Removing ground water faster than it is being replaced causing land on top of an aquifer to sink or buckle
