1.1.1 Incident Category
Removal Action
1.1.2 Site Description
The Wiley’s Bridge Lead Site (Site), located in along Wiley’s Ln., and on the Blue Falls Grove property, on the banks of, and possibly into the Maiden Creek, is owned by the City of Reading, and the private owner(s) of the Blue Falls Grove Property. The suspected area of concern, owned by the City of Reading appears to be an area of approximately a quarter, to a half mile along a stretch of Wiley’s Ln., on the bank of, and possibly into the Maiden Creek. Similarly, the initial area of concern on the Blue Falls Grove property appears to extent from Wiley’s Bridge, east along the bank of the Maiden Creek, for approximately one half mile. The actual size the impacted area of the Site may change following an extent of contamination investigation. During Site visits, adults have been observed fishing, and both adults and children have been observed swimming in affected area of Maiden Creek. The Blue Falls Grove Property is an active 38 acre RV, camp ground, fair ground, picnic area, and event (weddings, family/company events and picnics) destination. Families, including children, play, fish, and swim in the area of concern, and are potentially exposed to unsafe lead concentrations in the surface soil and debris at the Site. The Site is surrounded by rural residential property, and approximately 5,000 acres owned by the City of Reading. The Reading property consists of mostly wooded areas, with some hiking trails, and the Ontelaunee Reservoir, which serves as the public water supply for the City of Reading, and some surrounding areas.
The area of concern to the west of Wiley’s Bridge was investigated by the City of Reading in the early 1990’s. The results of the investigation indicated the presence of elevated lead concentrations and battery fragments in the surface and subsurface soils. It is not clear why the investigation did not continue, and necessary remedial action did not occur.
1.1.2.1 Location
Intersection of Wileys Ln. and Bowers Rd, Reading, PA 19605
1.1.2.2 Description of Threat
Lead-contaminated soils and soil containing lead-contaminated materials are located throughout the Site. While there is some vegetative cover around the Site, the vegetation does not adequately cover the soil to prevent potential exposure to lead contamination, the soil and waste material is often bare or very poorly vegetated. Residents around the Site, visitors, and trespassers onto the Site have unrestricted access to the contaminated soil areas. Contact with the soil and subsequent incidental ingestion of contaminated soil poses a significant threat to human health of nearby populations.
In the absence of cleanup activities, the Site poses a potential direct contact threat to human receptors (trespassers), as well as the potential for secondary contamination of private residences and businesses. Incidental ingestion of lead in the soil or sediment at the Site may result in increased blood lead levels. Lead is known to adversely affect the central nervous system.
The hazardous substances located in the soils at the Site include lead contaminated, exposed surface soil on an embankment, and on walking trails. There is insufficient vegetation to prevent the migration of the contaminated soil through erosion by wind or precipitation or movement through pedestrian traffic. Areas of erosion have been observed throughout the site. Lead contaminated soils could easily migrate downgrade to heavily used recreational areas and/or into the Maiden Creek.
Reports indicate that RAWA has supplemantal inlets located downstream of the site. They are located approximately 3/4 mile downstream, at the RAWA water treatment plant. These supplemental intakes are used in case there is a need to either blend water from Maiden Creek with the Lake Ontelaunee water, or to exclusively use Maiden Creek water.
1.1.3 Preliminary Removal Assessment/Removal Site Inspection Results
In May, 2014, PADEP Project Manager, Dave Hrobuchak contacted OSC Richardson regarding reports of battery fragments observed along Maiden Creek, near Wiley’s Bridge. On May 1, 2014, OSC Richardson joined PADEP Project Manager Hrobuchak for an initial assessment of the area of concern. Significant amounts of battery fragment waste was observed along Maiden Creek for about a quarter mile, on the bank of Maiden Creek. Five random discrete surface soil samples were collected and sent to a lab for analysis. Analytical results revealed lead concentrations of 15,803ppm, 23,378ppm, 33,884ppm, 55,063ppm, and 68,489ppm. All of the analytical results far exceed the area specific risk based action level of 572ppm (screening number used prior to the WBLC Actoin Memo, which establised an action level of 400ppm), established for the Price Battery Remedial Site.
Following the initial assessment, the EPA OSC again visited the Site. Walking along the bank of Maiden Creek, using an XRF, battery fragments and elevated lead concentrations were found not only in the initial quarter mile west of Wiley’s Bridge, but also on to the east of the Bridge, onto the Blue Falls Grove Property. ATSDR was consulted regarding the findings at the site, and support the proposed action. The City of Reading was also briefed on the concerns related the Site, and has granted EPA access to further investigate. EPA has also met with the owners of the Blue Falls Grove Property. After consultation with their respective attorneys, both the owner and lease purchaser granted EPA access to conduct investigation, and necessary remival activities on the Blue Falls Grove Property.
