This year, the competition was held with the Innovation Pavilion, and students participated from eight universities: Northeastern University, University of Hartford, University of Massachusetts at Amherst, Roger Williams University, Smith College, University of Maine, University of Connecticut, and University of Rhode Island. Nine undergraduate and nine graduate poster entries were displayed and judged, and the proximity to the Innovation Pavilion allowed for plenty of interaction and enthusiasm Undergraduate winners: among the students and entrepreneurs.

GWVTS Background Abstract Sediment Testing

The GWVTS was constructed in 2013 at the A study of a gravel wet vegetated treatment system (GWVTS) in the town of To determine if the sedimentation forebay was Town Beach in Bristol, Rhode Island, on Bristol RI was conducted to determine operational performance after it was working as designed, the sediment depth was Narragansett Bay. This bay, which is New Site Location installed. The GWVTS was installed to help mitigate bacterial and nutrient measured at various locations, as shown in the England’s largest estuary, is used for both issues in the receiving waters of Narragansett Bay. To determine how the image adjacent. It was found that the greatest recreational and commercial fishing. Due to depth was at the inlet, then steadily decreasing system is currently functioning, the water, sediment, and plants were studied. high bacteria and nutrient levels both away from the inlet pipe. The area on the left recreational and shellfishing uses have been Results showed that that the system currently meets RI storm water side shows a slightly higher sediment depth, impacted. This system is part of a larger effort management standards for bacterial and nutrient removals. However, harmful caused by growth of cattails. The town has not to manage runoff from urban areas, and invasive species were found within the system. While the system currently removed sediment since 2015. receives runoff from the adjacent 80.5 acre meets standards at its current limited maintenance, recommendations for suburban neighborhood. sedimentation removal and invasive species removal were suggested to extend the design life. Results of this study can be applied to assist other municipalities The GWVTS uses vegetation that specifically feeds on bacteria and pollutants while the in their maintenance of stormwater management BMPs to prolonging their water is filtered and then released into the bay. The first flush stormwater enters the inlet and flows through a sedimentation forebay and two vegetated cells before being design life. released as treated stormwater. The system helps improve water quality via sedimentation, filtration, vegetative uptake, evapotranspiration and surface storage.

In addition, samples were collected and measured for organic content at three locations. Results showed the organic content increased with distance away from the inlet. This was expected because sand (inorganic) settles out immediately while the slower settling organics are carried through the forebay. Decaying plants, especially cattails growing in the forebay, contribute to sediment thus decreasing the storage volume.

Samples from three different storm events were collected at four locations and tested Current Status (Fall 2018) Overall, the assessment of the Bristol Town Beach’s GWVTS unveiled current operating for enterococcus bacteria, nitrate, nitrite, TSS, turbidity, pH, and DO. The average conditions and some areas of concern were addressed to the Town when it comes to measurements over the three storm events are presented in the table below.
