A group of environmental researchers is calling for more comprehensive soil testing in the L.A. region after January’s fires. In a letter sent to Gov. Gavin Newsom last week, a dozen experts said the state should pay for widespread testing to ensure lots are safe to rebuild on.

The federal government has been in charge of cleaning up after the Eaton and Palisades fires, but have said they will not test soil for heavy metals and other toxins once lots are cleared.
