Groundwater & Water

coatings-environmental-management

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

Leachate-Treatment

The Little Bushy Warren waste collection site is used for the gathering of green garden waste for Hampshire. The green waste is composted in windrows, and turned into soil and lawn conditioners, woodchip mulch or pine bark. Two lagoons collect rainwater runoff from a four hectare hard-standing area for the compost windrows. Veolia asked for

auto recycling environmental site investigation

iEnvi was engaged by an automotive recycling company to undertake a preliminary site investigation at a recycling facility in Melbourne, Victoria. The company wished to refinance the site and require an assessment of the level of environmental and human health risk associated with the automotive recycling processes and chemicals at the site. iEnvi completed historical

acidic landfill remediation

  Large consistent volumes of landfill leachate emanating from a restored landfill site. The landfill had been used for many years, for the disposal of domestic and vehicle batteries and it was believed other wastes were also tipped. This leachate posed a threat to local surface and groundwater. Domestic landfill leachates can display a variety

construction-environmental-management

iEnvi were engaged by an engineering firm on behalf of a regional council to undertake a Construction Environmental Management Plan (CEMP) and components of an Environmental Impact Statement (EIS) for the construction of a sports complex. The CEMP was required for development approval of the site.  The construction processes included clearing of existing vegetation, major

erosion sediment control

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.

mixed wastewater reedbed systems

The wastewater was highly contaminated with amines and phenols (COD up to 5000mg/l). The facility used a batch processing method, which meant the water was highly variable, and very difficult to treat by conventional methods.  Starting with demonstration that soil based reed beds were the ideal solution as they were versatile enough to handle the

reed beds pesticide remediation

An old industrial site that had been used as a pesticide research and development facility required remediation. The ground and underlying aquifer was heavily contaminated with pesticides and other chemicals. Initially the contaminated soils were removed and partially treated by thermal desorption. Next, a groundwater treatment system was installed. This consisted of 4 reed beds

reed bed remediation

Airports typically have their own fire and rescue service, and often have a training area on site where they can practice various fire fighting scenarios. The water resulting from the training is generally contaminated with partially burnt fuels, and fire fighting foams. The foam is of particular concern, due to the environmental persistence of some
