The __________ water level of a well is measured when the pump is OFF.

The __________ water level of a well is measured when the pump is ON (aka pumping water level).

___________________ is measured by substracting the dynamic/pumping water level from the static water level.

An abundance of freely-moving water in an aquifer results in a ________ (high/low) drawdown.

The DNR's #1 cause for poor well capacity is a ___________ ______ __________.

The most common type of well used by municipalities for public water is a ___________ well.

Drilled wells can be drilled via cable-tool/percussion method (pounding/hammering, uncommon) or by hydraulic ____________ drilling (very common).

The main purpose of the _______ __________ is to prevent sand and gravel from entering the well during pumping.

Which location is better suited for a well: higher or lower on the landscape?

What material is used for well screens?

After a well is built or rehabbed, it needs to be ________________ before being put into service.

Well _________________ is the process of cleaning out clay/silt introduced into the well during drilling or cleaning.

How often must water levels be measured in municipal wells?

What naturally-occurring constituent of groundwater can accelerate corrosion of wells?

A ______ ______________ centrifugal pump is used to move water from surface water sources to the treatment processes/well house.

A ____ ____________ centrifugal pump is used to pressurized water and discharge it to a distribution system.

A _______ pump is used to move water from aquifers / groundwater to the treatment processes/well house.

A _________ pump is used to increase water pressure within the distribution system OR to move water to elevated storage tanks.

A ____________ ________ pump is used to add chemicals to water for treatment.

Chemical feed pumps will be which of the following two styles: centrifugal or positive displacement?

Centrifugal pumps are also known as ___________ pumps.

Which style of pump is better for pumping high volumes of water, albeit less precisely: centrifugal or positive displacement?

Which style of pump is better for pumping very precise volumes is smaller dosages: centrifugal or positive displacement?

A centrifugal pump moves fluid via ________________ energy which creates centrifugal force, velocity, and pressure.

A centrifugal pump motor spins the shaft and ______________, which "throws" water into the volute.

When water moves into the volute of a centrifugal pump, a __________ is created which draws in more water at the base of the impeller.

A pump casing transforms velocity (aka. movement of the water) into ___________ head.

The two types of pump casings are volute and ___________.

Which style of pump casing is spiral-shape and asymmetrical: volute or diffuser?

True or false: Centrifugal pumps DO NOT need to be primed.

True or false: A centrifugal pump can be adjusted by a water operator to change it's flow rate per unit pressure (ie. pump curve).

True or false: Positive displacement pumps DO NOT need to be primed.

Positive displacement pump efficiency (increases/decreases) with increasing pressure.

Which style of pump DECREASES in efficiency when pressure is exceedingly high or low: centrifugal or positive displacement?

A pump motor provides power and therefore __________ to the shaft and impellers.

The pump's packing is found on the pump ________ and is used to control the amount of pump leakage (pump leakage prevents overheating).

The pump's ___________ are fittings on the pump shaft designed to reduce wear to the shaft.

The pump shaft and impeller are found in the pump __________.

The pump motor sits on the _______ ________, which provides access for maintenance.

An alternative to pump packing is a ____________ _______.
