I believe the comment was to say you can not create a join for data that does not exist. Access to financial records is trivial, but there is likely no such comparable record that one can query on for water/industrial. Maybe metrics like water quality for some of them, but not the other security data exists other than shodan/censys (weak and out of context) which could take months per site to collect. AFAIK the most robust data they have on industrial sectors is within the national labs, and even then its considered sparse.
