Analysis and Sustainability of Four Constructed Water Features in the National Capital Region of the National Park Service
Tilley D, Williamson T, Zachritz W. 2016. Analysis and Sustainability of Four Constructed Water Features in the National Capital Region of the National Park Service. National Park Service
The National Park Service (NPS) considers constructed water features (CWFs) to be built features and elements that use water for aesthetic, narrative and/or utilitarian purposes in the landscape. CWFs include fountains, ponds, reflecting pools, canals, cascades, and reservoirs. The NPS has over 300 of these CWFs located in park units across the United States, but the National Capital Region (NCR), which includes parks in the District of Columbia, Virginia, Maryland and West Virginia, has the largest number of CWFs of any NPS region. In recent years, many of these features have been plagued by ongoing nuisance algae blooms that turn the water a green color throughout the summer months. Responses to these issues have been inconsistent and in most cases have not been effective or only temporarily effective. There is a need within the NPS and the NCR in particular to review the present approach to water quality control in water features, assess the options for implementing more sustainable technologies, and develop systematic methods to manage and control of these issues.
