Concern: widespread practice of withdrawal and injection into wells under development of un-characterized surface waters obtained from streams, farm ponds, or rivers while drilling or boring drinking water wells contaminates  groundwater with materials (see pollutants), and/or pathological organisms (bacteriological, viral & parasitic) which could threaten public health on or adjacent to permit holder's property. 

Reference: "G. Water used during well construction shall be obtained from a suitable source or the well being constructed.  A suitable source means a pure water source, or, when a pure water source is not locally available, water taken from another source then disinfected using compounds meeting NSF/ANSI Standard 60 environmental specifications." 

Private sanitary standards do not meet requirements of Code citation.
Therefore it is recommended requirement for disinfection be specified. 

Example given:  12VAC5-630-430. Disinfection. 

Minimum yield requirements increase cost to consumer, role of health officials should not include bullying citizens into drilling additional wells. The regulations are silent on the accepted means of determining well yield or storage capacity; thus the driller who has several conceivable conflicts of interest, is left to advise the property owner whether the yield is "sufficient." Water use is one parameter which is completely at the discretion of the homeowner.

Is there any data suggesting that 1/2 gpm well yield is insufficient for a 3BR home? A sewage permit would anticipate discharge of 450 gallons/day, while 1440 minutes/day gives 720 gallons from a so-called low yield well. The existing regulation has not proven problematic, and is certainly not a threat to public health or welfare.

Leave well enough alone.

12VAC5-630-460. Water system yields for residential use wells.

A. All drinking Drinking water systems that utilize one or more Class III wells shall be capable of supplying water in adequate quantity for the intended usage. All such systems, with Systems with a capacity less than under three gallons per minute, shall have a capacity ability to produce and store 150 gallons per bedroom per day and be capable of delivering a sustained flow of five gallons per minute per connection for 10 minutes for ordinary residential use. Systems with a capacity of three gallons per minute or more do not require additional storage.

B. The certified water well systems provider shall certify the storage capacity and the yield of the well on the Uniform Water Well Completion Report.

Please clarify who is licensed to design and permit construction of water wells.

Although VDH regulations require acceptance of well site design applications endorsed by PE, OSE or certified well driller the proposed regulations are silent on the vital issue of site plan, certification of meeting horizontal standoffs to easements, boundaries, and existing or proposed improvements. 

12VAC5-630-80. Relationship to the Department of Professional and Occupational Regulation.

Persons engaged in the construction, repair, or alteration of a private well shall be licensed and certified In in accordance with § 54.1-1100 §§54.1-1103 and 54.1-1129.1 of the Code of Virginia., any contractor constructing a water well to reach ground water shall possess, as a minimum, a valid Class B contractors license.
