I no longer watch TV, except in snippets. I’m such a cheapskate, plus I can’t stand commercial interruptions.
I thought it was a clip from a movie, actually. But I agree with everything he said.

Was she someone who cared about what he said? It looked like she was doing it on purpose, and that they were acquainted with one another.

It’s a whole character arc.
A close examination of the reservoir sediment using a technique called energy dispersive X-ray fluorescence spectrometry found that mercury did not leach into the water from the underlying bedrock. Likewise, Tankersley said, UC ruled out another potential source of mercury—volcanic ash that fell across Central America during the frequent eruptions. The absence of mercury in other nearby reservoirs where ash would have fallen ruled out volcanoes as the culprit.
Instead, Tankersley said, people were to blame.
“That means the mercury has to be anthropogenic,” Tankersley said.
With its bright red color, cinnabar was commonly used as a paint or pigment across Central America at the time.
“Color was important in the ancient Maya world. They used it in their murals. They painted the plaster red. They used it in burials and combined it with iron oxide to get different shades,” Tankersley said.

It may have enough rainfall, but it has a lot of limestone which doesn’t leave enough surface water. Settlements either need to store rainwater, or rely on sinkholes or well to deep aquifers. I don’t think they can afford to lose any of the available water to mercury or other poisons.
I don’t think it’s in the Puuc region.
Tikal, the city described in the paper, gets 1945 mm of rain per year today, though it’s unpredictable.
