Determination of Dicyclopentadiene and Its Derivatives as Compounds Causing Odors in Groundwater Supplies FRANCESC VENTURA,* JORDI ROMERO, AND JOAN PARE ´S AGBAR, Aigu ¨ es de Barcelona, P. Sant Joan 39, 08009 Barcelona, Spain
A study of organic pollutants causing odor events in the groundwater from the Lower Llobregat aquifer system has been conducted. This aquifer acts as water reserve of Barcelona (northeast Spain) when the quality of the raw water from the Llobregat River is low. Closed-loop stripping analysis (CLSA), purge-and-trap (P&T), sensory GC, and flavor profile analysis (FPA) have been used as analytical methodologies to identify the compounds responsible for the odor events. Industrial organochlorinated solventssdito hexachlorinated saturated and unsaturated hydrocarbonss dicyclopentadiene (DCPD) and its derivatives 8-dihydroDCPD, tetrahydroDCPD, and adamantane (the trimer of DCPD) are among the most significant compounds identified in the groundwater. DCPD with a mean concentration of
