What should be done after identifying the source of elevated contaminant levels?

After identifying the source of elevated contaminant levels, implementing remediation measures is crucial to address the contamination and mitigate its impact on public health and the environment. Remediation involves taking concrete steps to remove or neutralize the source of the contaminants, thereby helping to restore water quality and protect ecosystems. This action demonstrates a proactive approach to environmental management and public safety.

While documenting the findings is important for record-keeping and future reference, it alone does not resolve the issue of contamination. Increasing surveillance frequency may help monitor the problem more closely, but it does not actively address the contamination itself. Restricting public access to affected water bodies might be necessary in certain situations to protect public health, but it serves as a temporary measure rather than a permanent solution. Implementing remediation measures is the effective course of action to ensure a lasting impact on the environmental and public health concerns raised by the elevated contaminant levels.
