A Risk Analysis Framework for Evaluating On-Site Wastewater Treatment Systems
The Beaver Water District in Lowell, AR provides clean, safe drinking water to more than 300,000 residents in Northwest Arkansas. As a water utility, the Beaver Water Department is concerned with the potential of on-site systems (septic tanks) contaminating Beaver Lake – the area’s primary source of drinking water. The purpose of this study is to develop a framework to assess the risk potential of on-site wastewater treatment systems in the Beaver Lake Source Water Protection Area. Through a multi-year collaboration, more than 2,400 septic tank permits across two counties have been located, digitized, and used to create a geodatabase. Information from the geodatabase including the geophysical characteristics and system design of each septic tank are considered when assessing a system’s risk of contaminating Beaver Lake. Our risk framework, initial risk assessment, and potential intervention areas are presented.
