Notes - general: The construction of a road runway or other paved
surface on the outcrop of an aquifer introduceds an
impermeable area into an otherwise permeable
environment. Srface water must be drained from these
areas and the most conenient and inexpensive way of
disposing of this water is usually to lead into
soakaways in the saturated zone of the aquifer. This
approach is acceptable in that it can provide valuable
recharge to aquifers in times of low rainfall.
However it carries the risk that pollutants from the
surface can alsi be carried into the aquifer. These
pollutants can be generated from (a) normal abrasion,
(b) maintenance opertaions such as de-icing and
defoliation and (c) accidental spillages. Although
there is evidence that such drainage can carry a
pollutant load and that drainage entering soakaways
can reach a public supply well there does not seem to
be any evidence available at present of any public
supply in the UK being seriously affected by such
drainage.
