10. the combination of pipes and lawn underground that slowly seeps and spreads out
11. kills organisms due to dramatic changes in water temperature
15. directly produced from one location
16. legislation put in place for wildlife and marine life by maintaining and restoring the chemical, physical and biological properties of surface water
21. found in the middle, a fairly clear layer of wastewater
22. rubber-outlined pond containing manure from leaking into groundwater
23. sets the standards of safe drinking water
24. includes rain, snow, hail, fog, and even dust that is acidic and falls from the atmosphere to the ground

1. community or region that diffuses pollution
2. can dissolve in groundwater and is naturally present in high levels of groundwater

5. an abundance of fertility from the release of phosphorus and nitrogen
6. contamination caused by humans affecting marine life

9. oxygen quantity in water
12. large tank that then distributes the water through a leach field
13. rarely found in drinking water and is a naturally occurring toxic metal found in the earth's crust caused when ran through lined pipes or other materials
14. maximum concentration of contaminants able to be present in drinking water
17. produced by livestock operations, human activity, and sewage
18. humans causing changes to water temperature due to human activities
19. solid waste material carrying many pathogens
20. a way to determine if disease-causing pathogens are present through the use of organisms
