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

2012 is chosen as the baseline year as this was the first year after a major renovation and addition of new campus housing.

We identified a meter error in March of 2019 that was fixed in June of 2019. Unfortunately, some meters on campus had been measuring erroneously high water usage numbers for the previous three years. Therefore our water usage numbers reflected on water bills for 2016-19 are inflated and not 100% accurate. Analyzing historical spend, we computed a need to deduct 11,363,350 gallons from total water use these years and have done so in the above total.

Total building square footage is adjusted from the total campus building square footage to remove the building space at Cade Farm and the Ecology Center because these two agricultural locations are on well water and we do not have water use data.

Vegetated grounds acreage is so much less than total campus acreage because it does not include the acreage at Cade Farm and the Ecology Center (650.9 acres). These locations are on well water and therefore are not incorporated in the water use numbers.
