Personally, I believe assessing risks based on statistics and probability. There are no statistics showing the harmful effects of the Tustin soil and thus the probability of getting ill from it is pretty darn low.
When the local agency set/revise the zoning in the relevant area, they must reference the plume study, which is conducted at the state level thus having superior authority. If the threat exceeds certain level, they wouldn't allow the City for any land development. That's why you can find many former bases that are still closed down for remediation. Of course, if you don't believe in U.S. agencies, that is out of the scope of my discussion.
For the toxicity in the plume zone, you have to compare the actual disclosed monitoring data. Like I mentioned earlier, the plume would be moving and diffusing, which doesn't entirely justify that the source area is the most toxic. If you don't see any special action taken the agency, it means that the monitoring data is fine with the regulation.
