Primary Outcomes

Primary Outcomes (end points)
Public Valuation for Recycled Water; Willingness to Support Water Conservation
Primary Outcomes (explanation)
Public Valuation for Recycled Water will be assessed by a set of attitudinal questions
Willingness to Support Water Conservation will be measured by donation to a water conservation organization

Secondary Outcomes

Secondary Outcomes (end points)
Secondary Outcomes (explanation)

Experimental Design

Experimental Design
The experiment will be conducted in different locations (identified as fresh-water abundant, moderate, and scarce). The level of fresh-water abundance will serve as a natural between-subject treatment arm. In addition, we will introduce a message "Help Drought Areas, Support Water Recycling/Conservation" as another between-subject treatment.
