PUBLIC HEALTH ASSESSMENT
MOUNDSVILLE, MARSHALL COUNTY, WEST VIRGINIA
The Agency for Toxic Substances and Disease Registry (ATSDR) published a Site Review and Update (SRU) for the Hanlin/Allied/Olin (HAO) site on September 30, 1996. This Public Health Assessment (PHA) document has been developed by reorganizing information in the 1996 SRU into a format that conforms to ATSDR's Interim Guidance on the Structure of Public Health Assessments.
Chemicals were produced at the site from the 1950s to the early 1990s. Several waste impoundments and solid waste disposal units operated; almost all have been closed. Extensive decommissioning activities have been performed. The need for and type of future investigations and remediation is being decided between the site owners and EPA.
Plant operations had contaminated site soils and underlying groundwater, and may have contaminated air. The plant also released some contaminated waste water to the Ohio River. A fish advisory is in place for many miles of the river. The local public water system (Public Service District #2) draws water from a well located south of the plant; samples taken there show no evidence of contamination.
Community members expressed public health concerns associated with past plant operations, but had no current plant-related health concerns.
ATSDR concluded that exposures and any potential health consequences associated with past
plant operations could not be evaluated because of absence of key sampling data or the
uncertainty of exposure-related activities. ATSDR noted that naturally-occurring, nonsite-related,
sodium and manganese shown in samples of the Moundsville water supply are at levels that may have an adverse health effect in some persons.
The Agency for Toxic Substances and Disease Registry (ATSDR) prepared a Site Review and Update (SRU) in 1996 for the Hanlin/Allied/Olin (HAO) site in response to ATSDR's mandate to evaluate public health issues at sites proposed by the U.S. Environmental Protection Agency (EPA) for the National Priorities List (NPL).
ATSDR concluded that the data available were not adequate to evaluate contaminant exposures and possible health consequences potentially associated with past plant operations. ATSDR noted that naturally-occurring, nonsite-related, sodium and manganese shown in samples of the Moundsville public water supply are at levels that may have an adverse health effect in some persons.
