Who We Are

Stop Toxic Housing members began working in 2018 to address Los Angeles County problems of housing being built either on toxic-waste sites that were not fully cleaned up --- or in near-freeway areas where diesel particles, mainly from trucks, can be 7-25 times higher than in ambient air. The STH goals are to protect community members from toxic-waste sites and from air toxins on freeways, especially the air toxin of diesel particles. STH leaders are all volunteers and operate by consensus. They include health experts, housewives, Information- technology specialists, interior designers, media specialists, executives in nonprofits, scientists, and university professors.
