A brief description of when and why the water use baseline was adopted:

The new baseline water figured was adopted in 2021 due to the available of the most accurate set of data from 2017 to date. This baseline does not match what is stated in Marquette's current version of the Campus Sustainability Plan but will be used in the next version of the plan. It is also the baseline the Facilities Planning & Management team will use going forward to adopt new strategies to reduce water use.
