Not even close to a Curie of I-131 is ever used.  A typical well tracer job might involve 10 millicuries.  Further, these activities might be undertaken once a year or even much less frequently.

  Actually, I-131 is used in this industry, and injected into wells.  See, e.g.:

  or

  The question is, would it pose any residual hazard to members of the public using the site years later, and, I think the answer is "no."  Even if a Ci of I-131 were used in  a tracer study, ignoring the fact that it is injected down a deep well, it would only be about a millicurie within 90 days, a microcurie within 180 days, a nanocurie within 270 days, and a picocurie before the year was out.
