AB  - Syracuse, New York is working under a court-ordered agreement to limit combined 
      sewer overflows (CSO) to local surface waters. Green infrastructure technologies, 
      including green roofs, are being implemented as part of a CSO abatement strategy 
      and to develop co-benefits of diminished stormwater runoff, including decreased 
      loading of contaminants to the wastewater system and surface waters. The 
      objective of this study was to examine the quantity and quality of discharge 
      associated with precipitation events over an annual cycle from a green roof in 
      Syracuse, NY and to compare measurements from this monitoring program with 
      results from a roof irrigation experiment. Wet deposition, roof drainage, and 
      water quality were measured for 87 storm events during an approximately 12 month 
      period over 2011-2012. Water and nutrient (total phosphorus, total nitrogen, and 
      dissolved organic carbon) mass balances were conducted on an event basis to 
      evaluate retention annually and during the growing and non-growing seasons. These 
      results are compared with a hydrological manipulation experiment, which comprised 
      of artificially watering of the roof. Loadings of nutrients were calculated for 
      experimental and actual storms using the concentration of nutrients and the flow 
      data of water discharging the roof. The green roof was effective in retaining 
      precipitation quantity from storm events (mean percent retention 96.8%, 
      SD = 2.7%, n = 87), although the relative fraction of water retained decreased 
      with increases in the size of the event. There was no difference in water 
      retention of the green roof for the growing and non-growing seasons. Drainage 
      waters exhibited high concentration of nutrients during the warm temperature 
      growing season, particularly total nitrogen and dissolved organic carbon. 
      Overall, nutrient losses were low because of the strong retention of water. 
      However, there was marked variation in the retention of nutrients by season due 
      to variations in concentrations in roof runoff.
