A population of tiger salamanders, Ambystoma tigrinum, inhabiting a playa lake reciving treated domestic sewage were found to have a high incidence of tumors. Research was aimed at determining the causative agent of the tumors, determining the trasmittability of the tumors and to determine if conventional water treatment unit operations, coagulation and sedimentation, filtration and chlorination dould reduce the tumor incidence. Although no specific tumorigenic agent was positively identified, there was evidence to suggest that polycyclic aromatic hydrocarbons were the tumorigenic agents. Sources of these compounds, diesel oil and asphalt, were known to have been applied to the playa lake. It was also determined that the conventional water treatment unit operations employed had no effect on tumor incidence.
