Chesapeake Bay Program: Data sharing arrangement could lead to reduced pollution from onsite wastewater systems

Representatives from states across the Bay region recently signed a cooperative accord that will help reduce the amount of nitrogen flowing from onsite wastewater systems into local waterways.

At the Chesapeake Bay Program office last week, representatives from Delaware, Maryland, Pennsylvania, Virginia and West Virginia signed a Memorandum of Cooperation to share data related to the performance of advanced pretreatment technologies for “onsite wastewater treatment systems,” often called septic systems. Pretreatment of wastewater allows for the removal of potentially harmful pollutants such as nitrogen—but these technologies are often costly, and their approval takes time. Under the arrangement, information-sharing across states will help expedite the approval and deployment of these technologies, as well as offer cost savings to manufacturers and consumers.
