(Pronounced “Ka-Dah-Strel”). This refers to a rectangular coordinate system that is used to map much of Arizona. Arizona is divided into four unequal quadrants (A, B, C, D), with a north-south line called meridian and an east-west line called baseline. The northeast quadrant is “A”, the northwest “B”, the southwest “C”, and the southeast “D”.

From here, each quadrant is subdivided into Townships (capital “T”). Each Township is defined by a township (lowercase “T”) north or south of baseline and a range east or west of meridian.

Regularly sized Townships consist of 36 sections. Each section in a regularly sized Township is 1 square mile, or 640 acres in size. Each 640-acre section is then divided into four 160-acre quarters. Each 160-acre quarter is then subdivided into four 40-acre quarters, and each 40-acre quarter is subdivided into four 10-acre quarters.

On our wells 55 map, wells are plotted to the nearest 10-acre quarter or section, rather than the exact, physical location. For more information regarding the cadastral system, please view this pamphlet.

A waterway constructed for the purpose of transporting water to a point of delivery, including main canals and lateral canals.

A tamper-resistant, watertight steel plate of at least one-quarter inch thickness on the top of all inside and outside casings of a well. A.A.C. R12-15-801(6).

The tubing or pipe installed in the borehole during or after drilling to support the sides of the well and

prevent caving. A.A.C. R12-15-801(7).

Conservation Efforts Report required to be filed by a large municipal provider regulated under the Non-Per Capita Conservation Program as provided in Section 5-705(E).

"CERCLA" means the comprehensive environmental response, compensation, and liability act of 1980, as amended (P.L. 96-510; 94 Stat. 2767; 42 United States Code sections 9601 through 9657), commonly known as "superfund".

An industrial facility that produces or is designed to produce more than 25 megawatts of electricity by utilizing an internal combustion engine in which the expanding gases from the combustion chamber drive the blades of a turbine which turns a generator to produce electricity.

An area or areas owned and operated as a single integrated facility and used for recreational or open space purposes. A common area is maintained for the benefit of the residents of a housing development.

Community water systems are any system that serves 15 or more service connections, or which serves 25 or more residents, on a year-round basis. They are subject to water quality standards and more stringent reporting requirements A.R.S. §§ 45 341 to 343. Community water systems are also regulated by the Arizona Department of Environmental Quality.

This is a location included in the federal government’s "Superfund" program, which investigates sites that are contaminated with hazardous substances. The Superfund program develops remedial actions that assure the protection of public health and welfare and the environment. The CERCLA program is administered by the United States Environmental Protection Agency (USEPA). The CERCLA Act of 1980 is authorized by P.L. 96-510; 94 Stat. 2767; 42 United States Code §§ 9601 through 9657. A.R.S. § 49-201(4).

The relatively impermeable geologic unity immediately overlying an artesian aquifer. A.A.C. R12-15-801(8).

A component of recirculating water in a cooling tower, the concentration of which is not significantly modified by precipitation, loss to the atmosphere, or the addition of treatment chemicals. 

A naturally occurring geologic unit through or into which a well is drilled, having a composition, density, and thickness which will provide a natural hydrologic barrier. A.A.C. R12-15-801(8).

"Constructed underground storage facility" means a facility that meets the requirements of section 45-811.01 and that is designed and constructed to store water underground pursuant to permits issued under this chapter.

Use of water for construction purposes, including the use of water for dust control, compaction and preparation of building materials on construction sites.

Groundwater that has been contaminated by a release of a hazardous substance, as defined in section 49-201, or a pollutant, as defined in section 49-201. A.R.S. § 45-596(H1).

In contact at any point along a boundary, or part of the same master planned community. Two parcels of land are contiguous if they are separated only by one or more of the following: a road, easement, or right-of-way.

Patterns in cooling tower operation that include continuous blowdown and make-up or frequent periodic blowdown and make-up of recirculating water. 

If water from the proposed well, or existing well being modified or deepened, will be used for domestic purposes on a parcel of land of 5 or fewer acres, the applicable county or local health authority must endorse all items in Section 1 on the Notice of Intent (NOI) to Drill within one year before submission to the Department of Water Resources. A site plan must also be attached.

The ratio of the concentration of total dissolved solids, other conservative mineral constituent, or electrical conductivity in the blowdown water to the concentration of this same constituent or electrical conductivity in the make-up water. This can be calculated by dividing the total make-up water by the total blowdown water.
