Since its inception, CERCLA has evolved through various amendments and policy changes. The Superfund Amendments and Reauthorization Act ([SARA](https://)) of 1986 significantly expanded CERCLA's scope, emphasizing the importance of permanent remedies and innovative technologies. Continuous improvements in risk assessment methodologies and toxicological science have further refined the processes for evaluating and managing contaminated sites.
In conclusion, CERCLA is a pivotal law in the realm of environmental protection, with toxicology playing a critical role in assessing and mitigating risks associated with hazardous substances. Through rigorous scientific evaluation and innovative remediation strategies, CERCLA aims to protect human health and the environment from the dangers posed by contaminated sites.
