Water Quality

3. A commonly used bioindicator species, 5th month of the year in its name.
5. Water treatment step when microorganisms are killed/destroyed before the water is released into the environment.
9. A commonly used bioindicator species, 6 letters in its name, not an insect.
16. How fresh, potable, or livable a water source is.
17. Inverse relationship with dissolved oxygen.
18. Higher-than-normal amount of nutrients (nitrates/phosphates) in the water.
22. Amount of oxygen dissolved in the water.
23. Water treatment step that causes small clumps of organic particles in the water to stick together forming larger clumps called "floccs".
26. Water treatment step when tiny particles settle out to the bottom of a water treatment container and are removed from the water.
27. How safe a sample or body of water is to drink.

1. a rapid increase in algae on the surface of a body of water as a result of eutrophication.

4. A commonly used bioindicator species, 9 letters in its name.
6. Pollution for which we don't know the source.
7. Mineral that makes water look chalky and white.
8. Water treatment step when smaller objects and particles are filtered and removed from the water.
10. Water treatment step that causes small organic particles in the water to clump together forming small clumps of organic particles.
11. How acidic or basic a substance is.
12. often times enters the water through fertilizer runoff; causes eutrophication, algal blooms.
13. Water that is safe to drink.
14. how clear or cloudy water is.
15. Pollution for which we know the source.
19. Mineral that gives water a brown color and a smell like rotten eggs.
20. How many dissolved minerals are in a water sample; not life-threatening, just not preferable.
21. Organisms (usually insect larva) that indicate the health of a water ecosystem.
24. pH higher than 7.
25. pH lower than 7.
