Across
  1. 3. measurement of mineral content in water such as calcium and magnesium
  2. 5. water pH measurement that is less than 7
  3. 10. essential for strong bones and teeth, this mineral is leeched out of limestone
  4. 11. the shallow, highly productive area along the shoreline of a lake or pond where rooted aquatic plants grow
  5. 12. draining away of water and compounds from a surface, often a farm field or lawn ending up in an aquatic ecosystem
  6. 13. entering water through respiration of organisms and the atmosphere, this compound is essential for plant life
  7. 15. water pH equal to 7
  8. 17. while essential for healthy bones and teeth, excessive amounts come from septic tank discharge and lawn enhancing products
Down
  1. 1. excessive amounts of minerals, particulary phosphates that lead to excessive plant growth
  2. 2. aquatic plant eating insects, worms, clams, snails and other animals visible without aid of a that may be associated with or live on substrates such as sediments, supplying a food source for fish and other organisms
  3. 4. important compound that comes from the atmosphere and aquatic plants, necessary for life in ecosystems
  4. 6. water pH measurement that is more than 7
  5. 7. the study of freshwater quality and conditions
  6. 8. mineral that enhances growth and cellular function in plants and animals, enters water through runoff of rocks
  7. 9. as water used in the making of concrete and glass, this mineral is picked up as water flows through rocks
  8. 14. found in lawn fertilizers and septic tank discharge
  9. 16. water found beneath the soil surface and saturating the layer at which it is located
  10. 18. a measurement of how acidic or basic water is, dictates the diversity of life an an aquatic ecosystem
