12 Va. Admin. Code § 5-590-476 - Reactivation of wells
A. The
owner shall notify the department of the intent to reactivate a well.
B. Before bringing the well into service, the
well shall be pumped to waste (purged) for a minimum of five well volumes but
for not less than 30 minutes. The purged well water shall be discharged in a
manner so that it will not return to the well, directly or indirectly, during
the pumping period.
C. After the
well is pumped, water quality samples shall be collected. If the well has been
inactive for less than one year, then two samples shall be collected at least
30 minutes apart and tested for the presence of E. coli. If the well has been
inactive for one or more years, then it shall be tested for total coliform
density (MPN), nitrate, and, if determined by the department, inorganics, VOCs,
SOCs, and radionuclides. Satisfactory test results shall be obtained before
placing the well in service.
D. A
well yield and drawdown test may be required by the department before bringing
the well into service. The test shall be performed in accordance with
12VAC5-590-840
H, as applicable.
E. A well may be
activated for emergency use before receipt of satisfactory monitoring results,
even if public health and safety are unknowns and may be at risk, as determined
by the department. However, in these circumstances, a special water advisory
shall be approved by the department and issued by the waterworks at the same
time the well is activated.
