Level of ”Physical Risk QUANTITY” for the institution’s main campus as indicated by the World Resources Institute’s Aqueduct Water Risk Atlas:
Total water use (potable and non-potable combined):

	Performance Year	Baseline Year
Total water use	146,015,554 Gallons	191,653,126 Gallons

Potable water use:

	Performance Year	Baseline Year
Potable water use	146,015,554 Gallons	191,653,126 Gallons

Start and end dates of the performance year and baseline year (or three-year periods):

	Start Date	End Date
Performance Year	July 1, 2017	June 30, 2018
Baseline Year	July 1, 2009	June 30, 2012

A brief description of when and why the water use baseline was adopted:
Figures needed to determine "Weighted Campus Users":

Number of employees resident on-site	0	15
Number of other individuals resident on-site and/or staffed hospital beds	0	0
Total full-time equivalent student enrollment	18,413	21,486
Full-time equivalent of employees (staff + faculty)	2,845	2,850
Full-time equivalent of students enrolled exclusively in distance education	2,876	650
Weighted campus users	14,873.25	19,255

Potable water use per weighted campus user:

	Performance Year	Baseline Year
