Some parts of US EPA keep working.
They just released a "National Sewershed Dataset" of wastewater system boundaries for all 50 states and Washington, D.C.
Similar to the work done on the drinking water boundary side the last few years.

Colleagues Sam Sandoval, Erika Cassio et al @ucanrwater.bsky.social on the CA Wastewater Needs Assessment conducted a statewide survey of sanitation inequities.
Finding highlights (MHPs!) from the survey are below, and an extensive field campaign is ongoing

We are at the midway point of the State Water Resources Control Board's inaugural statewide Wastewater Needs Assessment.
Which investigates CA communities’ access to adequate wastewater & provides the Board recs on priorities and projects that support equitable access

Great new report by Urban Land Institute and UCLA/USC colleagues.
I was esp struck by extent of destruction to MHPs in the Palisades Fire.
And the extent of damage (but not destruction) to MFH esp in the Eaton fire.
