One third of jails and prisons in the US are less than 3 miles away from a Superfund clean-up site. Those are sites that are highly contaminated, that the EPA says 'nobody should be living here,' and it's definitely not coincidental - it's such a massive number... You have people reporting from many different jails that they have horrible medical problems. The consequences of building prisons in these super cheap, undesirable sites - I'm not sure if the people building these things really do not care - or they do take them into consideration, and it's another way of punishing.
