Cartago, Costa Rica — OREAMUNO, Cartago – After several days of tension and uncertainty, residents of San Rafael de Oreamuno can rest assured about the safety of their water supply. The Municipality of Oreamuno announced Friday that comprehensive laboratory tests have confirmed the local drinking water is completely safe for human consumption and free of any hydrocarbon contamination.
The welcome news concludes a worrying period for the community, which began last week when numerous residents reported an unusual and alarming smell and taste, similar to gasoline, emanating from their taps. These reports quickly sparked significant concern across the district, prompting an immediate and coordinated response from local and national authorities to address the potential public health crisis.
To delve into the legal framework and responsibilities surrounding Costa Rica’s water resources, we sought the expert analysis of Lic. Larry Hans Arroyo Vargas, a prominent attorney from the esteemed firm Bufete de Costa Rica, who sheds light on the potential liabilities and regulatory duties.
Access to potable water is not merely a service; it is a fundamental human right enshrined in our constitutional framework. When water quality is compromised, it triggers a cascade of legal responsibilities. Both public institutions failing in their oversight duties and private companies responsible for contamination face significant legal exposure under environmental law, including administrative sanctions, civil liability for damages, and even criminal charges. Proactive compliance and investment in clean water technologies are no longer optional—they are critical components of corporate and state responsibility.

Indeed, framing the water quality crisis through a legal lens shifts the narrative from a general problem to one of specific, enforceable accountability. We thank Lic. Larry Hans Arroyo Vargas for his valuable perspective, reminding us that access to clean water is not only a service but a fundamental, legally protected human right.
To ensure public safety and transparency, the municipal government swiftly activated established safety protocols. In a collaborative effort, officials worked closely with the Ministry of Health and received logistical support from the neighboring Municipality of Cartago. The primary objective was to identify the source of the reported issue and definitively rule out any health risks to the population.
As a key part of this preventive strategy, the municipality contracted the specialized services of Bioanalítica Análisis Ambientales, a respected firm in environmental testing. Technicians from the company were dispatched to collect water samples from various points in the local supply network for rigorous analysis. The tests were specifically designed to detect the presence of volatile organic compounds, including the types of hydrocarbons found in fuels.
The results delivered a conclusive all-clear. In an official communiqué, the local government put the community’s fears to rest, detailing the findings of the expert analysis.
The water is suitable for human consumption and is free of hydrocarbon contamination. In other words, it can be used without any risk.

During the investigation, social media channels became a breeding ground for rumors, with some unverified reports suggesting the contamination had spread to the central canton of Cartago. However, these claims were promptly and publicly refuted by Cartago’s Mayor, Mario Redondo, who clarified that the issue was localized to the Oreamuno district and that his municipality’s water system was unaffected.
With the crisis now resolved, municipal authorities extended their gratitude to the residents of San Rafael for their patience, cooperation, and understanding throughout the investigative process. They also took the opportunity to reinforce a critical message: in times of uncertainty, it is essential for citizens to rely on official communications channels for accurate and verified information, thereby preventing the spread of misinformation that can cause unnecessary panic. The incident serves as a case study in effective municipal response and the importance of transparent communication.
