Description:
Stormwater management is a growing challenge across the country. Water quality standards are becoming increasingly strict as new regulations are enacted. Meanwhile, changing land use and greater urbanization make meeting these standards even more difficult. Currently, stormwater samples are collected in the field and analyzed in the lab, a process which is time-consuming, costly, delayed and provides poor data resolution. Alternatively, in situ biosensors can offer real-time, online, continuous monitoring of stormwater quality by measuring water quality in a less labor-intensive, more efficient, and sustainable manner. These sensors have been pilot-scale tested in wastewater and groundwater applications. The objective of this Phase I grant was to further develop the current design for stormwater applications, validate it in a real environment, and explore its sensitivity to a broader range of contaminants.
Summary/Accomplishments (Outputs/Outcomes):
Phase I efforts show that the modified biosensor can support an active biofilm in real world applications for at least three months. This sensor proved robust and able to withstand difficult and dynamic environmental changes associated with the rainy season, while maintaining responsiveness to flow and water quality fluctuations. Further tests showed responsiveness to a wider variety of contaminants of concern, including eutrophication-associated nutrients.
