Well drillers, pump installers and well constructors shall, when requested by the department, give notice to the department, as specified in the notice of request, at least on the department work day prior to the day upon which any well construction or reconstruction or any part thereof, any well filling and sealing operation or the installation of any pumping equipment, will be commenced. Heat exchange drillers shall notify the department no less than one work day prior to constructing or reconstructing a heat exchange drillhole.
NR 812.03(3)
(3) Well and heat exchange drillers
and
well
constructors
shall
contact
the
department
to
determine
if
any

(4) Well
and heat exchange drillers
and
well
constructors
shall,
when
requested by the
department,
contact
the
department
to
determine
if
any
special construction is required if the well
or heat exchange driller or well constructor is engaged to construct a new well
or heat exchange drillhole or reconstruct an existing well because the existing well
or heat exchange drillhole is known to contain contaminants in excess
of the drinking water standards in ch.
NR 809.
