Water possibly originating from the landfill flooded the yards of several <br /> residences located downhill. Residents were also concerned that several seeps on <br /> their properties were discharging potentially contaminated water from the landfill. <br /> Ms. Racca researched the history of the landfill, collected and analyzed water samples <br /> from the seeps and small drainages on the residential properties. <br /> Phase 1 Environmental Site Assessments.yor 39 Shopping Centers, Donahue Schriber <br /> Realty Group, Various Locations, California, Nevada, Arizona.
