Physical properties of Dense Non-Aqueous Phase Liquid (DNAPL) are the following:
- Immiscibility with water - they form separate ‘phases’, eg. Oil & water
- Low solubilities - DNAPL can’t dissolve quickly in groundwater: it may persist for decades before dissolving
- Relatively high densities - DNAPLs are denser than water, and can therefore sink beneath the water table, polluting the full thickness of an aquifer
- Low viscosities - allows rapid subsurface migration
- Toxicity - Many DNAPLs are suspected or proven human carcinogens (cause cancer)
