Trinity Foundation
Vacant Land for Redevelopment


Bryan Environmental Consultants, Inc. (Bryan) performed a Phase I Environmental Site Assessment on vacant land proposed for redevelopment located in New Lenox, Illinois, on behalf of the Trinity Foundation. The vacant land is comprised of two lots that were zoned for a two-unit residential district, totaling 5.5 acres.

Bryan did not identify any Recognized Environmental Conditions (RECs) in connection with the Site or adjoining properties, but did identify two nearby properties with Controlled RECs (CRECs) as defined by the ASTM Standard E1527-13, meaning that they are facilities that have activity and use limitations, institutional controls or engineering controls in place. The two CRECs included a dry cleaner and farmland property with free diesel product in monitoring wells as a result of spills and dumping of fuel oil at a neighboring bulk petroleum storage facility. Bryan identified a data gap that could result in a REC, namely, the bulk petroleum storage facility located adjacent to the farmland property. Two other data gaps were identified—past historical use of the Site for farming, and piles of rubble and debris at the Site from demolished structures and unknown sources.

Bryan conducted a limited Phase II ESA investigation at the Site to address the data gaps and possible impacts from CRECs upgradient of the Site. Bryan notified the petroleum pipeline company that had underground lines at the Site of the planned drilling locations. Bryan sampled near-surface soils (0-12”) for possible heavy metals, pesticides and herbicides. Bryan drilled shallow soil borings (up to 20 feet deep), and installed temporary monitoring wells. Subsurface soils and groundwater were sampled and analyzed for the possible presence of total petroleum hydrocarbons (TPH) in the range of diesel-range organic compounds (DRO). Subsurface soils were sampled for gasoline indicators, benzene, toluene, ethylbenzene, and total xylenes (BTEX) and compared to Illinois Environmental Protection Agency (IEPA) Tiered Approach to Corrective Action Objectives (TACO) regulatory levels.
