Water Quality Assignment With your lab partner, 1) Choose one of the following water quality parameters, or one water contaminant. Water Quality Parameters (a select few) Dissolved Oxygen Temperatures pH Ammonia Phosphates Nitrates/Nitrites Water clarity/turbidity Contaminants (a select few) herbicides and pesticides Mercury, and other heavy metals VOCs PCBs Lead E. coli Pharmaceuticals Fire Retardants 2) Prepare 5-10 minute power point presentation on your topic, giving general information on your topic in regards to water quality. Be sure to define your topic and answer the following questions: (Always remember to cite your sources!!!) If you choose a water quality parameter: 1) How does this parameter influence aquatic life and human health? 2) What range is considered healthy for an ecosystem? 3) What factors can influence, or change, this parameter? (For example: What makes pH levels increase?) If you choose a contaminant: 1) What is the source of this contaminant? How does it get into the water? 2) Where does this contaminant go? (For example: Does it sink into the sediment, stay in the water, or does it get stored in animal tissues?) 3) How does this contaminant affect aquatic life, wildlife, and humans? Why is is a problem? 3) Be prepared to give your presentation by:________________________ Water Quality Parameter: __________________________ Definition/Description: Ideal Range: Influencing Factors: Influence on Aquatic Life and ecosystems: Influence on humans and human health: Water Contaminant: _________________________________ Definition/Description: Sources & Pathways: Sinks (places of storage): Influence on Aquatic Life and ecosystems: Influence on humans and human health:
