Abstract
Urban runoff, or stormwater, poses engineering challenges including increased flood risk and water quality impairment. Stormwater control measures (SCMs) are increasingly used to both mitigate the negative effects of stormwater and capitalize on stormwater as a valuable water resource. SCMs have been shown to provide water quantity benefits such as decreased peak flow and increased groundwater recharge. But the ability of SCMs to reduce pollutants is variable, prompting researchers and practitioners to develop enhanced SCMs with modified geomedia, plant and fungal processes, or hydraulic conditions to provide increased and more reliable pollutant removal. Examples of enhanced SCMs include open surface wetlands, biochar-amended biofilters, and detention ponds with real-time controls. This dissertation focuses on how these next generation SCMs can provide laboratory- and watershed-scale benefits. Chapter 2 investigates the use of wood-decay fungi to enhance biodegradation processes in stormwater at the laboratory scale. Batch studies indicate that the wood-decay fungi are capable of degrading the urban-use pesticide fipronil. Chapters 3 and 4 investigate the impacts of enhanced SCMs on stormwater quality at the watershed scale. Chapter 3 examines effects of implementing enhanced SCMs on fecal indicator bacteria (FIB) pollution in the Ballona Creek Watershed (Los Angeles County, CA). Chapter 4 examines urban-use pesticide occurrence in runoff and subsequent watershed-scale management of pesticides with SCMs in the San Diego River (San Diego County, CA). This work reveals enhanced SCMs provide water quality benefits in the laboratory that are scalable to the watershed level. Further, water managers should consider water quality and quantity goals concurrently when designing SCM networks.
