What are sediments? | Fragmented materials that originate from weathering and erosion of rocks or unconsolidated deposits and are transported by, suspended in or deposited by water. |
What are contaminated sediments? | Many sediments have been contaminated by pollutants some released years ago and others enter water every day. Some flow in water, others from runoff and others carried through the air. |

How much suspended solids do "primary treatment" and "secondary treatment" remove in wastewater treatment? | Primary removes about 60% of suspended solids (aeration occurs in this step) Secondary removes more than 90%. |
What can wastewater pollutants do to aquatic life? | Use of O2 in a lake so fish and other organisms cannot live, excessive nutrients like P and N cause eutrophication toxic to aquatic organisms -> excessive plant growth, alter habitat and decline in certain species; chlorine can be toxic to aquatic life. |

What is reactivity (characteristic waste)? | reactive wastes considered unstable under normal conditions. Can cause explosions, toxic fumes, gases or vapors when heated, compressed or mixed w/ water. |
What is toxicity (characteristic waste)? | Toxic wastes are harmful or fatal when ingested or absorbed. When toxic wastes are land disposed contaminated liquid may leach from waste and pollute ground water. |
