As a heat wave sweeps over Louisville, Homeless Services Director Jon Pilbean stressed the importance of hydration.

The Los Lunas Fire Department is providing bottled water and access to fill water jugs. That is starting at 4:30 p.m. Wednesday. People impacted can visit Fire Station 2 at 465 Sand Sage Road NW.

Gallon plastic water jugs are at the root of an ongoing and sometimes antagonistic standoff between Southern Arizona humanitarian groups and Buenos Aires National Wildlife Refuge officials.
