Transboundary water monitoring in Nogales revealed sewage system failures and potential hazardous waste dumping. Pollution impacted low-income areas, highlighting disparities in water access and quality.

Area of Science:

  • Environmental Science
  • Public Health
  • Water Resource Management

Background:

  • The Arizona-Sonora border region faces unique environmental challenges due to its transboundary nature.
  • Municipal infrastructure, particularly sewerage systems, can be a source of transboundary pollution.
  • Water quality monitoring is crucial for identifying and mitigating environmental risks.

Purpose of the Study:

  • To assess water quality in the Nogales area, specifically focusing on transboundary impacts.
  • To identify sources of pollution, including municipal sewerage deficiencies and potential industrial waste.
  • To evaluate the impact of pollution on different communities within Nogales, Sonora.

Main Methods:

  • Joint U.S.-Mexican water quality monitoring program conducted in 1990.

  • Analysis of sewage samples for pollutants, including volatile organic compounds (VOCs).
  • Sampling of municipal water systems and wells supplying water to specific neighborhoods.

    • Main Results:

    • Nogales, Sonora's municipal sewerage system exhibited deficiencies, leading to sewage spills and transboundary pollution.
    • Potential illegal dumping of industrial hazardous waste (VOCs) into the sewerage system was identified.
    • VOCs, commonly used by border industries, were detected in sewage and in wells supplying low-income neighborhoods.
    • Municipal water system samples showed no pollutants, but trucked water wells had VOC concentrations.

    Conclusions:

    • Sewerage system failures in Nogales, Sonora, pose a significant transboundary environmental risk.
    • Industrial hazardous waste (VOCs) poses a threat to water quality, particularly in vulnerable communities.
    • Disparities in water access and quality exist, disproportionately affecting low-income populations in Nogales, Sonora.
