				  NR
				  812.37. The injection of fertilizers or pesticides
				  into a potable well or water system is prohibited. No person may inject

				  fertilizers into a nonpotable well, well pump suction pipe, or pump column is
				  prohibited. No person may inject fertilizers into a nonpotable well, well pump
				  suction pipe, or pump column.
2.
				  Fertilizer may be injected in the discharge pipe of a booster pump delivering
				  water from a tank or sealed pond into which the well pump discharges through an
				  air gap from a point at least 2 discharge pipe diameters above the overflow
				  level of the tank or pond.
3.
				  Fertilizer may be injected into the well pump discharge pipe of a nonpotable
				  water system if it is injected with a positive displacement type chemical feed
				  pump or other approved equipment at a point downstream of a reduced pressure
				  principle backflow preventer which complies with ch. SPS 384 and is installed
				  in accordance with ch. SPS 382 or downstream of an UL approved check valve
				  installed in the well pump discharge pipe at the well site. The chemical feed
				  pump shall be shut off at least 10 minutes prior to shutting off of the well
				  pump so as to purge the chemical from the water system.
4. Fertilizer may be introduced into the well
				  pump discharge pipe of a nonpotable water system if it is aspirated into the
				  well pump discharge pipe with a venturi-type aspirator and the injection point
				  is downstream of a barometric pipe loop extending at least 35 feet above the
				  highest part of the downstream discharge piping.

				  of means for the measurement of static and pumping well water levels for any
				  high capacity well and may require the operator of the well to submit monthly
				  reports of this information. Installation shall be made in a manner as to
				  prevent entrance of contaminants to the water system and in compliance with
				  approval conditions and as depicted in Figure 3 of ch. NR 812 Appendix.
(a) When an air line with altitude gauge is
				  installed in a well, the equipment and installation shall meet the following
				  requirements:

				  not housed in a pumphouse or other structure, that portion of the air line
				  extending above the pump discharge head or well seal, and to a depth of at
				  least 3 feet into the well, shall be metal or shall be fiber or wire-braided
				  reinforced tubing. An "air quick-disconnect" fitting shall be installed for the
				  top of the air line such that the altitude or pressure gauge may be easily
				  removed and stored in a dry place when water levels are not being measured. The
				  "air quick-disconnect" fitting shall be installed to point downward or shall be
				  capped such that contaminants cannot enter the air line.
2. A silicone rubber sealant or a watertight
				  threaded metal fitting shall be used to seal the opening in the pump discharge
				  head or the well seal through which the air line extends.
