Environmental Delineation Investigation at Industrial Site in Northwest Sydney

by
cleanout access

iEnvi completed a Delineation Investigation (DI) at an aerosol and paint manufacturing site in northwest Sydney. The DI installed three groundwater monitoring wells, 13 soil bores and two stormwater points, collecting 8 groundwater, 39 soil and 2 stormwater samples. Findings showed minor soil hydrocarbons (one local exceedance), groundwater elevated dissolved metals likely related to background geochemistry, and isolated vapour-intrusion exceedances — prompting targeted sub‑slab vapour testing and further risk-management recommendations to meet NSW EPA expectations.
