be permitted in areas where a minimum separation of three feet r
between the bottom of the disposal field and the maximum seasonal i
ground water elevation or impermeable layer cannot be maintained.
The health officer shall require such greater vertical separation
as needed to protect health when the aquifer is used for a
potable water supply. The health officer may reduce the vertical
separation provided -the -local health department has in effect
an adequate designer program as described in WAC 248-96-130.
However, in no case shall the separation be less than one foot.
