Florida has established guidelines to encourage recycling and use of recycled materials in a manner protecting public health and the environment. Recovered screened material (RSM) generated at a construction and demolition (C&D) debris recovery facility is a recycled material with reuse potential. In order to reuse RSM, it must be shown that the material poses no significant threat to public health or the environment. The Sun Recycling facilities in Broward and Palm Beach counties are C&D facilities, generating RSM (i.e., soil with wood, concrete, other C&D particles) through mechanical separation using screens. The process generates RSM meeting state requirements for industrial, commercial, and residential use. RSM was used on residential lots in Miramar to elevate low areas (excluding building pads). In accord with Broward County Environmental Protection Department (EPD) and Palm Beach County Department of Health (DOH) permits, Sun facilities perform regular testing of RSM. RSM tests showed arsenic (As) concentrations below state criteria. Quarterly testing did not detect VOCs, SVOCs, or pesticides. RSM was delivered to homesites and mixed with existing site soil. To address concerns raised by some residents, Miramar hired a consultant to collect samples for arsenic and total recoverable petroleum hydrocarbons (TRPH), resulting in reports of some As levels above residential criteria. Further sampling/analysis of RSM and local soils in the neighborhood were performed by Broward EPD and Sun. Results of As and speciated TRPH analysis performed by the Miramar, Broward EPD, and Sun will be discussed. A consensus conclusion of acceptable conditions was reached by all parties.
