Dear Property Owner/ Occupier,

Groundwater Contamination Investigations – Keswick

The Environment Protection Authority (EPA) is writing to you in relation to groundwater (bore

water) contamination which has been identified in the Keswick area. You have been sent this

letter because the EPA has identified that a groundwater bore is registered to this property. If

you are not using the groundwater, this advice will not affect you.

This information is initially being sent to all land owners and occupiers of properties with a

registered groundwater bore on their property in the vicinity of the investigation area. The

EPA will be following up this letter with information for the broader community in early

January 2014.

As a precaution, the EPA and the Department of Health are advising you to not use

groundwater (bore water) for any purpose until further notice. Bore water is water that

is typically taken from beneath the ground through a pump or well located on a

property. Mains tap-water and rainwater are not affected.

The EPA was provided with a groundwater monitoring report detailing the presence of

historical groundwater contamination in the Keswick area on 18 December 2013. The

groundwater monitoring report identified the presence of chemical substances in groundwater

at concentrations above the Australian Drinking Water Guideline values1.

The chemical substances identified included trichloroethylene (TCE), vinyl chloride (VC) and

tetrachloromethane in groundwater. TCE is an industrial solvent and tetrachloromethane was

historically used as a refrigerant product. VC is a substance formed through the breakdown

of TCE.

Experience worldwide has shown that these types of industrial solvents were commonly

disposed of or leaked from storage tanks to underlying soils. Once in the soil, these chemicals

can move down to the water table and contaminate groundwater. As groundwater moves

beneath the soil surface the groundwater contamination can move underneath other land.

Strategy. National Health and Medical Research Council, National Resource Management Ministerial Council, Commonwealth of Australia, Canberra.

The area of the groundwater contamination has not yet been determined and more

investigation is required. It is not yet clear who caused this contamination, and further

environmental investigations will be undertaken following advice from the EPA. This work will

be completed in a staged approach and the EPA will provide further updates as information

becomes available.

If you have any concerns or questions, or if you would like to discuss this letter with an EPA officer,

please call the EPA toll free on 1800 729 175 (8am to 6pm weekdays, excluding public holidays)

or contact the EPA by email at epasitecontam@epa.sa.gov.au.

Dear Property Owner/ Occupier,

Groundwater Contamination Investigations – Keswick

The Environment Protection Authority (EPA) is writing to you in relation to groundwater (bore

water) contamination which has been identified in the Keswick area. You have been sent this

letter because the EPA has identified that a groundwater bore is registered to this property. If

you are not using the groundwater, this advice will not affect you.

This information is initially being sent to all land owners and occupiers of properties with a

registered groundwater bore on their property in the vicinity of the investigation area. The

EPA will be following up this letter with information for the broader community in early

January 2014.

As a precaution, the EPA and the Department of Health are advising you to not use

groundwater (bore water) for any purpose until further notice. Bore water is water that

is typically taken from beneath the ground through a pump or well located on a

property. Mains tap-water and rainwater are not affected.

The EPA was provided with a groundwater monitoring report detailing the presence of

historical groundwater contamination in the Keswick area on 18 December 2013. The

groundwater monitoring report identified the presence of chemical substances in groundwater

at concentrations above the Australian Drinking Water Guideline values13

.

The chemical substances identified included trichloroethylene (TCE), vinyl chloride (VC) and

tetrachloromethane in groundwater. TCE is an industrial solvent and tetrachloromethane was

historically used as a refrigerant product. VC is a substance formed through the breakdown

of TCE.

Experience worldwide has shown that these types of industrial solvents were commonly

disposed of or leaked from storage tanks to underlying soils. Once in the soil, these chemicals

can move down to the water table and contaminate groundwater. As groundwater moves

beneath the soil surface the groundwater contamination can move underneath other land.

The area of the groundwater contamination has not yet been determined and more

investigation is required. It is not yet clear who caused this contamination, and further

environmental investigations will be undertaken following advice from the EPA. This work will

be completed in a staged approach and the EPA will provide further updates as information

becomes available.
