- The party primarily at fault for the water crisis in Flint, Michigan was the governmental agencies. The two main government agencies at fault are the Michigan Department of Environmental Quality and the Environmental Protection Agency, they failed to properly monitor and respond to the major issues that came up involving the water quality, despite receiving very early evidence of there being contamination (Sullivan, 2017). Although others, including city officials and water treatment personnel, share some blame, it was the systemic failures within governmental bodies that allowed the crisis to escalate. Regaining public trust after a significant blow requires transparency, accountability, and meaningful action. Being transparent with the public involves providing accurate information, and letting the public be fully aware of the inter-workings of governmental agency actions. Being accountable involves acknowledging past mistakes, such as putting out a statement admitting fault to how…a) What substances can make water in lakes and ponds hard? b) Are these substances generally harmful or are they beneficial to organisms living in the water?Please provide an example of a water-borne disease outbreak.
