Water quality and environmental legal actions reported across Argentina

Various legal and regulatory actions regarding water quality and environmental protection are unfolding across different regions of Argentina.

In San Luis, the state agency San Luis Agua has intensified monitoring of reservoirs and rivers in the Ayacucho department. Sampling was conducted at the Luján dam, the Quines River, and several streams to analyze physicochemical and microbiological properties. These checks are vital for the Luján aqueduct, which supplies water for human, livestock, and agricultural use.

In Buenos Aires province, a landmark judicial ruling has ordered ABSA and the provincial government to ensure tap water meets the Argentine Food Code standards. The decision follows a 16-year legal battle by residents of 9 de Julio regarding arsenic, nitrate, and fluoride levels. The court set an arsenic limit of 0.01 mg/l and recognized the importance of access to potable water as a fundamental right.

In Entre Ríos, Federal Justice has authorized the collection of water samples from the Uruguay River. This measure is part of an environmental damage prevention lawsuit against a project by HIF Global to install a fuel plant in Paysandú, Uruguay, near the coast of Colón, Argentina. A biological expert will conduct physicochemical and microbiological analyses to assess potential impacts on the shared river system.
