Phase 2 Site Investigation Management Plan : Fire training or AFFF Areas
KEY AND POTENTIAL ISSUES
POTENTIAL CONTAMINANTS OF CONCERN

Soil
Heavy Metals (predominantly lead)
ASSESSMENT CRITERIA
KEY INVESTIGATION CONSIDERATIONS


1. NEPM 1999 (soil)
Identify all Fire Pits or AFFF areas (above and below
ground) by means of a desk study and walkover survey


Fuel/oil spillage can impact soil quality
Total Petroleum Hydrocarbons
(TPH)

2. ANZECC 2000 (water)

VOCs often not found in soil (low partitioning coefficient) but
vapour identified (high vapour pressure).

Contaminant transfer by direct / indirect contact

Benzene, Toluene; Ethyl Benzene, Xylene
(BTEX)


Contaminant transfer by ingestion / inhalation

Polynuclear Aromatic Hydrocarbons
(PAH)
Dutch Intervention or USEPA
3. EPA 1994 (hydrocarbons)

VOCs often found in groundwater.

Use of PID instrumentation to monitor air quality of samples
criteria may be used in the
Groundwater

Phenols

Fuel/oil spillage can impact groundwater quality

Volatile Organic Compounds

Contaminant transfer by direct / indirect contact

Methylene
absence of any published and
blue
activating
(VOC)
substances
approved Australian guidelines
to aid scheduling.

Ensure investigation in all areas extend beneath pit depth.

Ensure installation of groundwater wells to monitor impacts.

Consider what chemicals were used to light the fire.

Receptors
(MBAS)
(Indicator) AFFF

Contaminant transfer by ingestion / inhalation

Sulfonates AFFF
(PFOS)
MANAGEMENT
CONSIDERATIONS

Surface Water
Glycol ethers AFFF
(DGBE)

Operate a permit to work
system


Fuel/oil spillage can impact surface water quality

Surface run off can impact drainage systems

Contaminant transfer by direct / indirect contact

Legal framework

Contaminant transfer by ingestion / inhalation

Best practice management
Documentation of past,
present and proposed
activities
techniques
Air


Contaminants may migrate in the form of dust

Contaminant transfer by inhalation
Use of instrumentation to
monitor
explosive
atmospheres to protect the
workforce (use of intrinsically
safe equipment).
