The unit “cfu/100 mL” refers to the number of colony forming units in a 100 millilitre sample. It is a biological measure of viable bacterial cells in the water.

Electrical conductivity is measured in units of micro Siemens per centimetre (µS/cm). It is an indication of the amount of nutrient, impurities or salts in solution.

 

Pollution Incident Response Management Plan (PIRMP)

Whylandra Waste Depot Sampling Results

An extensive ongoing environmental monitoring regime has been conducted at the Whylandra Waste Disposal Depot (WWDD) since January 1998. The WWDD is operated in accordance with the licence number 6058 issued by the NSW Environmental Protection Authority (EPA) under Protection of the Environmental Operations Act 1997 (POEO Act). The EPA licence describes the monitoring requirements (ie monitoring point locations, sampling methods, frequency of measure and sampling parameters) of surface water, groundwater, leachate and landfill gas. Under recent changes to the POEO Act, licencees are required to publish environmental monitoring data that has been collected as a result of a licence condition, in accordance with section 66(6) of the POEO Act.
