Isolated wells or cisterns unassociated with other remains will be treated as follows.
  (1) Isolated wells or cisterns that post-date 1900 A.D. do not warrant notification of THC or additional investigation. Removal or sealing of these features does not constitute an adverse effect.
  (2) Isolated wells or cisterns that pre-date 1900 A.D. require research and documentation of their location, construction, condition, and original context. Upon completion of the research and documentation, these features may be backfilled and capped. These activities do not constitute an adverse effect.
