Water Pollution

3. one source of heavy metals such as lead, arsenic, and mercury
6. A chemical compound found in crude oil which is toxic to many marine animals and can kill them
7. a phenomenon that causes rapid growth of algae (algae bloom) and eventually lack of oxygen in a body of water
9. an act that was put into place in 1972, which was set to protect wildlife and our water sources.
13. also known as escherichia coli, could mean that there is more of a chance of wastewater pathogens in your water
15. a chemical transformation of mercury that can be toxic to humans and damage the central nervous system
17. solid waste which comes from wastewater and will sink to the bottom of the septic tank
18. industrial compounds that are used to manufacture plastics that are very bad for the environment
21. an area to dispose of large amounts of manure from animals. It is like a pond lined with rubber to prevent leakage
22. an endocrine receptor that is used to control weeds and prevent crop loss (herbicide)
23. a part of a house's septic system in which wastewater goes into. here the wastewater sits and separates before going onto the leach field

1. you can tell waste and pollution is coming from this point
2. a column of oil migrating from the explosion site on the ocean floor up to the surface
4. a species like coliform bacteria that indicates when disease-causing pathogens are in the water
5. when there is not one point which pollution comes from, it is diffused from an area
8. when there is a change in the water temperature that is so dramatic and outside the organism's range of tolerance so they die off
10. an oil cleanup method that contains the spread of the oil, and then vacuums the oil off of the surface of the water
11. a harmful chemical that is banned in many nations but can still be found in sediments. when exposed to this chemical, falcon eggshells thin (causing them to die before hatching)
12. sewage treatment that is used in many rural areas
14. chemicals like arsenic that can cause cancer
16. a type of chemical which can negatively affect an animal's hormonal system
19. happens because of bioaccumulation when fat-soluble compounds build up as you get higher in the trophic pyramid
20. the measure of oxygen being used in a body of water
24. an area that's so depleted of O2 that little life can survive there
