Groundwater & Water

  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

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

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

hydrogeology water contamination

iEnvi was engaged by a Council north of Brisbane, QLD, to review environmental authority (EA) compliance, groundwater trends and risks at five landfill sites. A comprehensive data compilation and transformation was undertaken, along with a data quality review. Statistical analysis of the data was completed including the basic statistics (average, minimum, maximum, 80th and 120th

manufacturing environmental site investigation

As contaminated land consultants, a large part of what we do involves the investigation and remediation of soil and groundwater that has been exposed to liquids that are hazardous to human and ecological health. These liquids are often flammable and combustible liquids such as petroleum hydrocarbons and phenols, but when flammable and combustible liquids are

Guidelines for Water Quality

  The Australian and New Zealand governments have collectively established and promoted guidelines to manage both countries water quality for over 25 years. (previously referred to as ANZECC & ARMCANZ 2000) assist water practitioners with tools and guidance to assess, manage and monitor the water quality of aquatic systems in Australia and New Zealand As of

iEnvi has undertaken soil vapour sampling, using the implementation of the ASC NEPM, to identify potential risks of vapour intrusion regarding human exposure on various sites. Vapour intrusion is vapor-forming chemicals migrating from a subsurface source into an overlying building as well as basement carparks, trenches/pipes and conduits.  The requirement for vapour assessment as part
