When addressing a vacant lot used for dumping, what is the first appropriate action for an REHS?

The first appropriate action for a Registered Environmental Health Specialist (REHS) when addressing a vacant lot used for dumping is to contact the owner about health dangers. This step is crucial because it establishes communication with the property owner, who has a legal responsibility for their property. Informing the owner allows them to understand the potential health risks associated with the dumping, such as exposure to hazardous materials, contamination of soil and water, and public health implications for nearby residents.

While cleaning the site immediately might seem like a proactive measure, it can be premature without first informing the owner, as unauthorized cleanup could lead to legal issues or might not address the root cause of the problem. Posting "No Dumping" signs can help deter future dumping but does not address the immediate health dangers that existing waste poses. Involving local law enforcement is typically reserved for issues of criminal activity or when there is immediate public safety danger, which may not be the priority step in this scenario. Therefore, reaching out to the property owner is the foundational action that enables further steps to be taken safely and effectively.
