The 1 Hour Martinizing Cleaners site, EPA ID 110004254654, is currently on the National Priorities List with an active status. This location is a primary source of mercury contamination, a persistent heavy metal that does not break down in the environment. Exposure pathways include the inhalation of mercury vapors, ingestion of contaminated groundwater, and direct contact with polluted soil. Mercury exposure poses severe health risks, particularly targeting the central nervous system, kidneys, and developing fetuses. Nearby residents should also monitor the Orange Valley Regional Ground Water Contamination site, which impacts local aquifers. To defend against these risks, residents should first utilize high-quality HEPA air filtration systems to capture indoor particulate matter. Second, install certified water filtration systems capable of removing heavy metals if utilizing local well water. Third, implement a strict no-shoes policy indoors to prevent the tracking of contaminated exterior soil into living spaces. These measures reduce the cumulative toxic load from the 47 high-risk sites located within five miles of Caldwell. Constant vigilance is necessary as regulatory agencies continue long-term remediation efforts across the region to mitigate these documented environmental threats.
