Industrial Polychemical Services Corporation (IPS)

IPS is a business that manufactures adhesive cement, cleaners and primers for piping systems and other specialty products such as repair adhesives. IPS operation occur on eight parcels on South Main St. and South Broadway St. in Gardena, within a commercial area. The IPS manufacturing process uses chemicals tetrahydrofuran (THF), 2-butanone/methyl ethyl keton (MEK), cyclohexanone and acetone. IPS uses or has used in the past, small quantities or trichloroethene (TCE), methyl methacrylate monomer and methylene chloride. Investigations performed at IPS have revealed elevated levels of volatile organic compounds (VOCs). VOCs below ground at IPS impacted soil, soil vapor and groundwater. Environmental investigations and remediation have been occurring at the location since 1986. Air sparging and soil vapor extraction (SVE) remediation occurred at the Site between 1999 and 2013. As directed by DTSC, air sparging and SVE remediation activities ceased in February 2013. A rebound study was performed in 2014 which indicated no significant recurrence of VOC concentrations. Subsequently, DTSC issued a No Further Action letter for vadose zone soils (top of ground surface to water table) and soil vapor, dated February 2016. The Final Removal Action Work Plan (RAW) focuses on remediation of groundwater. The groundwater is contaminated with VOCs such as carbon tetrachloride, chloroform, 1,1-dichloroethane, 1,2-dichloroethane, 1,1-dichlorethene, 1,2-dichloropropane, 1,2 dichloropopan, tetrachloroethene, and 1,1,2-trichlorotrifluroethane [Freon113] and chloropicrin.
