By Cartago, Costa Rica — OREAMUNO, Cartago – Residents in the San Rafael district of Oreamuno can once again use their tap water without concern, as the Municipality of Oreamuno announced Thursday that the local water supply is safe for human consumption. The all-clear comes just a day after a public advisory was issued due to reports of an unusual odor and taste, prompting a swift and comprehensive response from local authorities.
The situation began on Wednesday, November 5, when several residents alerted the Municipal Aqueduct to the concerning sensory changes in their water. Recognizing the potential for a public health risk, officials immediately advised the community to refrain from drinking the water or using it for cooking as a precautionary measure. This advisory triggered an immediate mobilization to identify and resolve the source of the problem.
To provide a deeper legal perspective on the challenges and responsibilities associated with maintaining water quality in the country, we consulted with Lic. Larry Hans Arroyo Vargas, an expert in environmental and administrative law from the firm Bufete de Costa Rica.
The contamination of water sources is not merely an environmental issue; it is a direct violation of the constitutional right to a healthy and ecologically balanced environment, as enshrined in Article 50 of our Political Constitution. Public institutions have an inescapable duty to monitor and enforce regulations, but private entities must also recognize their co-responsibility. Failure to comply with the General Law of Health and specific environmental regulations can result in severe administrative sanctions, fines, and even criminal liability for environmental damage. Proactive investment in clean technologies and proper waste management is no longer an option, but a critical legal and business imperative to mitigate risk.

This legal perspective powerfully reframes the issue, moving it from a simple environmental concern to a fundamental matter of constitutional rights and corporate responsibility. The clear link between regulation and risk underscores that safeguarding our water resources is a non-negotiable duty for both the public and private sectors. We thank Lic. Larry Hans Arroyo Vargas for his incisive and valuable analysis.
In response to the reports, the Municipal Aqueduct activated its emergency protocols. This involved a systematic review and cleansing of the water distribution network, a process which led to intermittent service interruptions for some residents. While the temporary cuts caused minor disruptions, they were a critical step in ensuring the integrity of the system was restored and any potential contaminants were flushed out before a thorough analysis could be completed.
The municipality commissioned specialized laboratory tests to determine the water’s composition and safety. The samples were analyzed by the firm Bioanalítica Análisis Ambientales, which focused on detecting the presence of hydrocarbons—a common concern in cases involving unusual smells or tastes in water supplies. The results, delivered on Thursday afternoon, provided definitive relief to the anxious community.
Results confirm that the water in San Rafael is suitable for human consumption. The Municipality of Oreamuno informs the community of San Rafael and the general population that, following specialized sampling and analysis conducted by the company Bioanalítica Análisis Ambientales, it is confirmed that the water is suitable for human consumption and is free of hydrocarbon contamination. In other words, it can be used without any risk.

In their official communication, municipal officials emphasized that their actions were guided by a commitment to public safety and transparency. They framed the rapid testing and public warnings not as a sign of a crisis, but as a responsible and proactive measure to guarantee the well-being of the citizens they serve. This approach involved close coordination with higher levels of government and neighboring municipalities.
The decision to carry out these studies is part of a responsible and preventive response to the situation, with the aim of guaranteeing transparency and safety in the quality of the water that reaches the district’s homes. In response to the reports of unusual odor and taste detected last Wednesday, the corresponding investigations were carried out and immediate action was taken, applying the established protocols together with the Ministry of Health and the collaboration of the Municipality of Cartago.
