Across
  1. 9. The spillage of water over a river’s banks due to heavy rain or snowmelt.
  2. 13. The removal of salt from seawater to generate fresh water for human use.
  3. 15. Water that is relatively pure, holding very few dissolved salts.
  4. 16. A specific spot—such as a factory—where large quantities of air pollutants or water pollutants are discharged.
  5. 18. The water from precipitation that flows into streams, rivers, lakes, and ponds, and (in many cases) eventually to the ocean.
  6. 20. Landscaping using plants that are adapted to arid conditions.
  7. 21. The release of matter or energy into waters that causes undesirable impacts on the health and well-being of humans or other organisms.
  8. 23. (1) An artificial water body behind a dam that stores water for human use. (2) A location in which nutrients in a biogeochemical cycle remain for a period of time before moving to another of its kind. Can be living or nonliving entities.
  9. 27. The entire area of land from which water drains into a given river.
  10. 28. Term describing a water body that has high-nutrient and low-oxygen conditions.
Down
  1. 1. A water-bearing, porous layer of rock, sand, or gravel that is trapped between an upper and lower layer of less permeable substrate, such as clay.
  2. 2. Use of fresh water in which the water from a particular aquifer or surface water body either is not removed or is removed only temporarily and then returned.
  3. 3. A stage of wastewater treatment in which biological means are used to remove contaminants remaining after primary treatment.
  4. 4. The upper limit of groundwater held in an aquifer.
  5. 5. A water-bearing, porous layer of rock, sand, or gravel that lies atop a less permeable substrate.
  6. 6. Use of fresh water in which water is removed from a particular aquifer or surface water body and is not returned to it.
  7. 7. The region of land over which a river has historically wandered and periodically floods.
  8. 8. Any water that is used in households, businesses, industries, or public facilities and is drained or flushed down pipes, as well as the polluted runoff from streets and storm drains.
  9. 10. A diffuse source of pollutants, often consisting of many small sources.
  10. 11. A system in which the soil is saturated with water and which generally features shallow standing water with ample vegetation.
  11. 12. An underground water reservoir.
  12. 14. Term describing a water body that has low-nutrient and high-oxygen conditions.
  13. 17. Water located atop Earth’s surface.
  14. 19. A stage of wastewater treatment in which contaminants are physically removed.
  15. 22. An area where the ground has given way with little warning as a result of subsidence caused by depletion of water from an aquifer.
  16. 24. A wastewater disposal method, common in rural areas, consisting of an underground tank and series of drainpipes.
  17. 25. Any obstruction placed in a river or stream to block the flow of water so that water can be stored in a reservoir.
  18. 26. An area where water infiltrates Earth’s surface and reaches an aquifer below.
