Such models can also be applied whenever an accident threatens the quality of the
water supply. However, they must be used with great care as the mathematic
simulations relate to the laws of hydro-mechanics and do not concern themselves
in the main with chemical exchange processes between water and organic matter,
sand, mud or clay mineral particles.
