Health Assessment for Henderson Road National Priorities List (NPL) Site, Upper Merion Township, Montgomery County, Pennsylvania, Region 3. CERCLIS No. PAD009862939

摘要

The 8-acre Henderson Road National Priorities List site is located in Upper Merion Township, Montgomery County, Pennsylvania. The injection well was used to dispose of industrial wastes during the 1970s. Various volatile organic compounds and phthalate compounds were detected in the well. The primary environmental pathway of concern related to this operable unit is groundwater. The primary potential human exposure pathway is ingestion of contaminated groundwater. Current and future private well users and users of the McIlvain Well are the primary potential receptors of concern. Other human exposure pathways of concern are possible inhalation of volatilized contaminants and direct dermal contact with contaminated groundwater during indoor water use by off-site groundwater users.
