If you are interested in opposing a permit sought for a well, one important thing to know is that there are different state regulations for a bored Individual Residential or Irrigation Well than for a drilled one. These specific regulations are clearly identified here. Certain applicable regulations are listed on other pages so make sure you follow the appropriate link below to access all relevant additional information. Also, some regulations use technical words or phrases. These words or phrases are often linked to a list of definitions. Note that the S.C. Department of Health and Environmental Control has a very helpful website on residential wells available here. The information presented in this section is in alphabetical order rather than in order of importance.

If a well uses a chemical feed system for any reason other than water treatment an approved backflow prevention device is required. This device must be installed so that it precludes a direct pathway for any contaminant to enter an underground source of drinking water.
Bored wells must be more than 15 feet deep.
When completed, a residential or irrigation well must be disinfected. Any time there is maintenance, repair, pump repair, pump installation or testing a well must also be disinfected. Disinfectants placed in a well must provide a chlorine residual between 50 ppm to 250 ppm for at least 4 hours before being flushed from the well. Chlorination shall insure uniform distribution of the chlorine in a well. Afterward, a well must be sufficiently flushed to remove the disinfectant and condition the well for use.

Operations and Maintenance
Underground sources of drinking water and public health must be protected from contamination by any residential or irrigation well operation. The well must be operated and maintained at all times to achieve this. If appropriate, the well owner must also protect against vandalism. The well driller is responsible for making sure the well is constructed properly but the owner is responsible for the well's normal wear. Each drilled, but not bored, well must have a sampling spigot installed.
Plumbness and Alignment: wells must be constructed to be plumb and straight enough that no interference is caused with their intended use.
Within 30 days of completing well construction, a Water Well Record Form 1903 or other approved form must be completed and submitted to DHEC by the contractor or owner. In addition to the well record, if chemical or bacterial results or pumping information is available this must also be submitted. If a well is abandoned a Form 1903 must be submitted as well.
When completed, a residential or irrigation well must be labeled with an identification plate. The plate must be constructed of durable, weatherproof, rustproof material. The ID plate must be secured permanently to the well casing or enclosure floor around the casing where it is readily visible. It must permanently marked to show:
Well Tested for Yield
If conducted, a yield test shall be done by a standard method and shall accurately measure flow. DHEC must receive a copy of the results with the well record.
More information about all these requirements maybe found at the DHEC link above or through S.C. Code Regs. 61-71(F) and (G), available here.
