Across
  1. 3. oxygen The amount of oxygen present in water in a dissolved state
  2. 6. flow The relatively steady flow of water in a stream that is produced primarily from groundwater entering the stream.
  3. 7. groundwater.
  4. 10. water Water on the surface, as lakes and rivers, in contrast to that underground
  5. 15. a body of permeable rock which can contain or transmit groundwater
  6. 16. discharge The point during a stream flood event when the discharge is the greatest
  7. 17. Nitrate is nitrogen (N) combined with oxygen (O) and is the form of nitrogen most used by plants. All nitrates are water-soluble and, when applied in excess in fertilizer, move with surface waters to
  8. 18. The process of turning a vapor into a liquid
  9. 19. Phosphorus combined with oxygen. Phosphates are important plant nutrients, often as a major element in fertilizers. When they are when applied in excess in fertilizer, they move with surface waters
  10. 21. The passage of water through a plant from the roots through the vascular system to the atmosphere
  11. 23. can produce algal blooms in aquatic ecosystems.
Down
  1. 1. Water within the earth that supplies wells and springs
  2. 2. The seepage of water into soil or rock

  4. 5. coliform The bacteria (enterococci) that exist in the intestines of warm-blooded animals and humans and are found in bodily waste, animal droppings, and in soil
  5. 6. oxygen demand The amount of dissolved oxygen required to oxidize all the reactive biological and chemical parts of a water sample
  6. 8. The total stream discharge of water, including both surface and subsurface flow.
  7. 9. The downward movement of water through the soil in response to the pull of gravity
  8. 11. above 7.0 are alkaline with low acidity, and those below 7.0 are acid.
  9. 12. The addition of sediment as by flowing water
  10. 13. pH A numerical measure of acidity or hydrogen ion activity of water. The neutral point is pH 7.0. All pH
  11. 14. An area bounded by geographic features in which precipitation is absorbed in the soil to form groundwater which eventually emerges to become surface water and ultimately drains to a particular watercourse or body of water
  12. 20. solids A measure of all the suspended, colloidal, and dissolved solids in a sample of water.
  13. 22. Cloudiness of water caused by the presence of colloidal matter or other finely divided suspended matter.
