the hierarchy of controls are implemented to prevent injury, illness and disease to
persons who might be exposed to risks arising from well construction activities.
(d) This CoP does not include specific requirements for water quality sampling, yield
testing and final utilization of the well water, which shall be as established by
concerned local and federal authorities.
(e) “Principal Contractor” when used in this CoP refers to the main contractor overseeing
the operation and responsible for activities undertaken on the site within the Building

pipe that is inert to most naturally occurring substances.
(xviii) Gravel Pack - granular material introduced into the annulus between the well
hole and a casing or perforated lining to prevent or control the movement of
finer particles from the aquifer into the well.
(xix) Groundwater – (underground water) water that is held in the ground.
(xx) Grout – a fluid mixture of cement and water of a consistency that can be pumped
through a pipe, to which other additives (eg. bentonite) may be added to
enhance its properties. Sometimes called “cement grout” or “cement slurry”.
(xxi) Grouting - the operation of placing or pumping a grout into an annular space or
cavity.
(xxii) Head - see formation pressure.
