  1. Establish no regulations until there are conclusive scientific studies.
  2. Set the acceptable levels of the chemical conservatively low,  and keep them there unless future studies show that they can be safely raised.

  4. Caution  individuals  to  use  their  own  judgment  in  deciding  whether  to  drink  water  from  a  potentially contaminated area
