The Alliance for a Healthy Tomorrow (AHT) is a coalition of citizens, scientists, health professionals, workers, and educators seeking preventive action on toxic hazards. 

Founded in 2004, AHT is coordinated by Clean Water Action/Clean Water Fund Massachusetts.

Their goal is to protect people from toxic chemicals.  They advocate for a precautionary approach, with chemicals tested before they are put in consumer products and released to the environment.  They fight for the elimination of toxic hazards known to harm health and the environment.
