12 Va. Admin. Code § 5-630-360 - Classes of water wells

Classes of private wells established for purposes of this chapter are in addition to those established in the current Waterworks Regulations (12VAC5-590) and are intended for use for private well systems:

1. Class III - Private wells constructed to be used as a source of drinking water. There are three subclasses:

a. Class IIIA - Drilled wells in which the annular space around the casing is grouted to a minimum depth of 20 feet.

(1) The well shall be drilled and cased to a depth of at least 100 feet.

(2) The cased drill hole shall pass through at least 50 feet of collapsing material such as caving sand, gravel, or other material that will collapse against the casing.

b. Class IIIB - Drilled wells in which the casing is installed to a minimum depth of 50 feet and the annular space around the casing is grouted to at least 50 feet.

c. Class IIIC - Drilled, bored, driven, or jetted wells other than Class IIIA and Class IIIB.

2. Class IV - Private wells constructed for a purpose other than use as a source of drinking water. There are three subclasses:

a. Class IVA - Drilled wells in which the annular space around the casing is grouted to a minimum depth of 20 feet.

(1) The well shall be drilled and cased to a depth of at least 100 feet.

(2) The cased drill hole shall pass through at least 50 feet of collapsing material such as caving sand, gravel, or other material that will collapse against the casing.

b. Class IVB - Drilled wells in which the casing is installed to a minimum depth of 50 feet and the annular space around the casing is grouted to at least 50 feet.

c. Class IVC - Drilled, bored, driven, or jetted wells other than Class IVA and Class IVB.

3. Conversion of well class. A Class IV well may be converted to a corresponding Class III well provided the well meets (i) the location and construction standards set forth in this chapter and the water quality standards set forth in 12VAC5-630-431 and (ii) a construction permit application and a revised uniform water well completion report form are submitted to the department.
