GROUNDWATER - RESIDENTIAL WELLS
BENDIX CORPORATION/ALLIED AUTOMOTIVE
ST. JOSEPH, BERRIEN COUNTY, MICHIGAN
The groundwater in a plume under a residential area near the Bendix Corporation/Allied Automotive NPL site contains various volatile organic chemicals, including 1,1-dichloroethane, 1,2-dichloroethane, 1,1-dichloroethylene, cis-1,2-dichloroethylene, trans-1,2-dichloroethylene, 1,1,1-trichloroethane, trichloroethylene, and vinyl chloride, at concentrations that might pose health hazards if the water is used for household purposes, based on the maximum concentrations found in monitoring wells. Several private household wells in the area have been sampled, and water from the wells had much lower quantities of the same chemicals or are no longer known to be used for household purposes. Other residential wells located in the plume are currently no longer is use but have never been sampled, though they were taken out of use after the contamination plume probably reached their locations. Most residences in the area are connected to the municipal water system. The contaminants in the groundwater include several probable or known carcinogens, such as 1,2-dichloroethane, trichloroethylene, and vinyl chloride, and exposure might result in adverse health effects after long latency periods.
Residents of the area might also be exposed to volatile contaminants that have evaporated out of
the groundwater and migrated to their basements. Direct leakage into the basements is unlikely,
since the water table is far below the typical basement. There is no data and no way to estimate the concentrations.
Sample all private wells in the area, whether they are in use or not, to further establish the location of the contaminant plume and provide some information on the residents' exposure history.
All private wells in the area should be properly abandoned and all residences connected to the municipal water system, to reduce the likelihood of future exposure.
Offer residents of the area, especially long-term residents, and their physicians information on the potential health impact from their possible past exposure to groundwater contaminants.
Sample the air in any basement in the neighborhood for the VOC contaminants.
If any citizen has additional information or health concerns regarding the groundwater near the
Bendix Corporation/Allied Automotive site, please contact the Michigan Department of
Community Health, Environmental Epidemiology Division, at 1-800-648-6942.
