Groundwater Wells & Permitting

(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 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).

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 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).

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).

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.
