(225 ILCS 732/1-25)
    Sec. 1-25. Setbacks and prohibitions.
    (a) Except as otherwise provided in this Section, no well site where high volume horizontal hydraulic fracturing operations are proposed, planned, or occurring may be located as follows. Unless specified otherwise, all distances shall be measured from the closest edge of the well site:
        (1) within 500 feet measured horizontally from any
    
residence or place of worship unless the owner of the residence or the governing body of the place of worship otherwise expressly agrees in writing to a closer well location;
        (2) within 500 feet measured horizontally from the
    
edge of the property line from any school, hospital, or licensed nursing home facility;
        (3) within 500 feet measured horizontally from the
    
surface location of any existing water well or developed spring used for human or domestic animal consumption, unless the owner or owners of the well or developed spring otherwise expressly agrees or agree in writing to a closer well location;
        (4) within 300 feet measured horizontally from the
    
center of a perennial stream or from the ordinary high water mark of any river, natural or artificial lake, pond, or reservoir;
        (5) within 750 feet of a nature preserve or a site on
    
the Register of Land and Water Reserves;
        (6) within 1,500 feet of a surface water or
    
groundwater intake of a public water supply; the distance from the public water supply as identified by the Department shall be measured as follows:
            (A) For a surface water intake on a lake or
        
reservoir, the distance shall be measured from the intake point on the lake or reservoir.
            (B) For a surface water intake on a flowing
        
stream, the distance shall be measured from a semicircular radius extending upstream of the surface water intake.
            (C) For a groundwater source, the distance shall
        
be measured from the surface location of the wellhead or the ordinary high water mark of the spring.
    The distance restrictions under this subsection (a) shall be determined as conditions exist at the time of the submission of the permit application under this Act.
    (b) Notwithstanding any other provision of this Section, the owner of a water source identified in paragraph (4) of subsection (a) of this Section that is wholly contained within the owner's property may expressly agree in writing to a closer well location.
    (c) It is unlawful to inject or discharge hydraulic fracturing fluid, produced water, BTEX, diesel, or petroleum distillates into fresh water.
    (d) It is unlawful to perform any high volume horizontal hydraulic fracturing operations by knowingly or recklessly injecting diesel.
