Groundwater Hydrocarbon Sheen vs. Measurable LNAPL: What’s the Difference and When Must You Notify the EPA in Australia? Understanding the Difference Undissolved hydrocarbon (i.e. fuels and oils) contamination in groundwater may appear as either a sheen or measurable Light Non-Aqueous Phase Liquid (LNAPL). Knowing the difference is critical for assessing risk and ensuring compliance with

Project Overview: iEnvironmental Australia (iEnvi) conducted a Delineation Investigation (DI) at anindustrial site located in the northwest of Sydney, following a request from the NSW EPA based on the findings of potential risk in a baseline environmental investigation. The site, involved in aerosol and paint manufacturing, required a thorough assessment to determine contamination levels and

iEnvi previously prepared a long term environmental management plan (LTEMP) for a coatings manufacturing facility after a detailed site investigation (DSI), remediation and validation of soil groundwater were completed, to set out the principles for long term environmental management of residual solvent hydrocarbon contaminated groundwater and soil at the site. The LTEMP was also a

‘Slug tests’ are are commonly used as part of a risk assessment to help us determine groundwater contaminant flows. In this case groundwater and dissolved petroleum hydrocarbon horizontal flow velocity and contaminant transport risk offsite from a facility to the north of Sydney. Our graduate Jessica showed her handy skills by putting together this beautifully

Envi was engaged by a construction company to review and update the erosion sediment control plan (ESCP) as part of the construction environmental management plan (CEMP) for a State Significant development site in the Mornington Peninsula, Victoria. The update was necessary to address inadequate erosion sediment controls of the original ESCP identified at the site.
