regarding the extent of travel of chemicals from the JPL site. Upon
release, NASA invited broad review and discussion of its study. NASA has
received the following comments on the study:

NASA is thoroughly reviewing all comments submitted and plans to discuss its
review with commenters and with regulatory agencies that oversee the

The NASA report stresses the importance of considering the information
generated by all the tools together to best understand the complexities of
underground conditions and the existence of perchlorate in local
groundwater. NASA continues to have confidence in its study and in the
conclusions reached.
NASA looks forward to continued scientific discussions and to determining
appropriate next steps.
