The 1 Hour Martinizing Cleaners site, identified by EPA ID 110004254654, remains on the National Priorities List with an active status. Primary contaminants are listed as unspecified hazardous substances, though historical dry-cleaning operations frequently involve volatile organic compounds like perchloroethylene. Exposure pathways include vapor intrusion into residential basements and the migration of contaminated groundwater plumes. Chronic exposure to these substances increases the risk of liver damage, kidney issues, and neurological impairment. The high density of surrounding industrial sites, including Universal Chain Company and Electronic Mfg Co, complicates the local environmental profile. Residents should take three defensive measures: install a high-quality carbon air filtration system to mitigate indoor air pollutants, use bottled water if your property relies on private well water, and seal any cracks in basement floors or foundations to prevent soil gas entry. Detailed cleanup progress and sampling data are available through the EPA Superfund site profile. Continuous monitoring is required as cleanup efforts remain ongoing to prevent further environmental degradation and public health impacts in the Maplewood area. Every property owner should review local groundwater maps.
