Chloroform Toxic Substance FOUND in soil gas
2/22/2024: Chloroform was detected in sample B36-5 at a concentration of 86 ug/m3 which exceeded the commercial/industrial SGSL of 18 ug/m3 for chloroform.
Present in soil, soil gas and groundwater samples - testing indicates on-site release Soil gas concentrations (used to test vapors in air) exceeded commercial/industrial SGSL.
Substance: Chloroform is a dense, sweet-smelling liquid used as an anesthetic and also to produce resins, pesticides and refrigerants.
Present in soil gas. Concentrations exceed commercial/industrial SGSL
Exposure Pathways & Community Considerations: Release of trapped vapors from construction, particularly excavation can expose or disturb contaminated soil.
Subsurface pathway alteration can create soil gas migrations, allowing chloroform to move more freely.
Soil moisture changes from construction activities that alter moisture content influencing volatilization. Natural emission of chloroform can reach beyond legally permissible exposure limits
Inhalation, ingestion of contaminated water or food, or dermal contact Residents near hazardous waste sites or pulp mills may be exposed, as chloroform can leach into groundwater or evaporate from landfills.
Chloroform is highly mobile and prone to leaching in groundwater.
Risk to Human Health: Central Nervous System (CNS) depressant Acute exposure affects the central nervous system (dizziness, nausea, headache), while chronic exposure can damage the liver (hepatitis, jaundice) and kidneys.
This report presents a summary of work conducted by PARTNER. The work includes observations of site conditions encountered and the analytical results provided by an independent third-party laboratory of samples collected during the course of the project. The number and location of samples were selected to provide the required information. It cannot be assumed that the limited available data are representative of subsurface conditions in areas not sampled.
Conclusions and/or recommendations are based on the observations, laboratory analyses, and the governing regulations. Conclusions and/or recommendations beyond those stated and reported here in should not be inferred from this document.Partner warrants that the environmental consulting services contained herein were accomplished in accordance with generally accepted practices in the environmental engineering, science, geology, and hydrogeology fields that existed at the time and location of work.
