Environmental Aspects

A key part of an Environmental Management System is identifying and then managing the impacts our operations have on the environment. These impacts are called aspects, and they include everything from the disposal of paper waste to the proper use of water treatment chemicals.

While we manage many environmental aspects, some have a greater potential for substantially impacting the environment, and these are called significant aspects.

Charleston Water evaluates our environmental aspects annually. This helps ensure we have adequate control methods to prevent adverse impacts to the environment.

Our current environmental aspects are listed below by department. For more information about our environmental aspects or our EMS program please contact the Executive Office at (843) 727-6856 or info@charlestoncpw.com.
