b. Passive sub-slab depressurization
c. Block-wall depressurization
,d. Sub-slab depressurization - ANSWER-d. Sub-slab
depressurization
If one were to treat radon in the water supply of a home,
the water would be treated at:
Select one:
a. Each water tap in the house
b. The point the water is supplied to the home
c. Only the water taps from which people would draw

should always be placed on the perimeter of the slab.
b. Drill the vacuum-cleaner suction hole near the expected
location of the suction pipe; drill one test hole as far away
as possible.
c. Drill the vacuum-cleaner suction hole near the expected
location of the suction pipe; drill pressure-measurement
, test holes on opposite sides of things like grade beams
that could block air movement, as well as the furthest side
of the slab.
d. Place the vacuum-cleaner suction hole in the center of
the slab; placement of the test holes is not important. -
ANSWER-c. Drill the vacuum-cleaner suction hole near
the expected location of the suction pipe; drill pressure-
measurement test holes on opposite sides of things like
grade beams that could block air movement, as well as
the furthest side of the slab.
Measurements in the suction pipe or an active soil
depressurization system indicate flows of 150 cfm and
suction of 0.1 inch of water (WC). From the available
information, which of the following would be the most
