(1) 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.
(3) Well and heat exchange drillers and well
				  constructors shall contact the department to determine if any special
				  construction is required if the well or heat exchange driller or well
				  constructor proposes to construct or reconstruct a well or heat exchange
				  drillhole on a property that is located within the service area of a
				  municipally owned water system.
(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.

					 department as having residual contamination and continuing obligations can be
					 found by searching the Wisconsin Remediation and Redevelopment Database which
					 is available on the department's website at dnr.wi.gov, search
