The methods for properly inspecting and maintaining stormwater treatment practices are often ambiguous and inconsistently applied. Maintenance practices must constantly adapt to changing conditions. At the 2020 Central States Water Environment Association Anunal Meeting, we presented specific guidelines for practices involving media filtration, infiltration, and stormwater ponds because these tend to be widely implemented and often unsatisfactorily maintained. How do you know when enhanced media or amendments are no longer effective and should be replaced? Why do some infiltration practices fail while others succeed, and how do you prevent failure? Are stormwater ponds really removing phosphorus? Of special note are new assessment and maintenance methods, such as testing enhanced filtration media that target dissolved constituents, maintaining proper vegetation coverage in infiltration practices, and preventing phosphorus release from stormwater ponds.
