Water Quallity: Populations most at risk and current events

I have attached the instructions for the assignment. This is part of a group presentation, and my part will be “Identify populations most at risk for negative health outcomes related to exposure. (e.g., ages, pre-existing health conditions, income levels, gender, ethnicity, race)?” and “Present information on current events related to your topic”. 

There are links in the attached document to use as references, but you are not limited to them.

Thank you in advance.
