77 Ill. Adm. Code 920.30
General Requirements
Section 920
Section 920.30Â General
Requirements
a)        Authorized Constructor. Water wells subject to this Part
shall be constructed only by persons having a valid license under the Illinois
Water Well and Pump Installation Contractor's License Act unless exempt under
that Act.
b)        Reports. Within 30 days after a water well has been
constructed or deepened, the contractor shall submit a report of construction
to the Department, an approved unit of local government or local health
department (see Sections 920.150 and 920.160) on forms prescribed and furnished
by the Department.
c)Â Â Â Â Â Â Â Â Variance
1)Â Â Â Â Â Â Â Â If conditions exist at a proposed installation site that
preclude compliance with this Part, a variance shall be requested and shall be
approved before well construction begins. The contractor may request a variance
by submitting to the Department or an approved unit of local government or
local health department, a written request outlining a specific proposal to be
used in lieu of compliance with this Part. The request shall include a plot
plan of the property, showing lot size, the location of sewers, septic tanks,
buildings, seepage fields, and other sources of contamination on the property
and adjacent property, with distances shown to the proposed well. A description
of geological and soil conditions shall also be included. The Department or
approved local health department will approve the variance if the proposal is
in accordance with accepted public health and sanitary engineering principles
and practices, and if the resulting water well installation can be expected to
provide a continuously safe and sanitary water supply. The Department or
approved local health department will notify the applicant in writing of its
decision either to grant or deny the variance.
2)Â Â Â Â Â Â Â Â Examples of location problems that would preclude compliance
with this Part would be the proposed location of a well too close to septic
tanks, buildings, sewer lines, or barnyards.
3)Â Â Â Â Â Â Â Â Examples of public health and engineering principles that
would be considered in issuing a variance would be ground surface conditions,
depth of the water table, the location of sources of contamination, the ability
of the existing soil to remove bacteria and geologic conditions.
4)Â Â Â Â Â Â Â Â After a well has been drilled for which a variance has been
issued, the contractor shall submit two water samples to the Department
laboratory for analysis. The first sample shall be submitted within 30 days
after the pump is installed and operated; the second sample shall be submitted
within 60 days after start-up of the pump, but not less than 30 days after
collection of the first sample.
