The ATSDR tested for hazardous materials in the water, air and soil in order to determine whether the health of the Viequenses were at risk. It found that either the Navy had not affected the environment or that the Navy had affected it so minimally that the contamination would pose no threat to human health. However, other scientists contend that ATSDR's studies were incomplete. The ATSDR is notorious for denying links between community contamination and health affects. After monitoring the ATSDR for ten years, Linda King of the Environmental Health Network reported that only one ATSDR study among hundreds has found contaminants in the community to be the cause of health problems.
