BACKGROUND

Groundwater is an essential resource for domestic use, agricultural needs, and economic activities, yet it is increasingly threatened by contamination and overextraction. To evaluate groundwater quality and identify associated health risks, the Philippine Groundwater Health Index (PGHI) project conducted a comprehensive assessment of selected sites across various regions in the country.

METHODS

The study analyzed groundwater samples from multiple locations to determine compliance with the Philippine National Standards for Drinking Water. Parameters assessed included organochlorines, heavy metals, microbial indicators, and physical and nonmetal characteristics such as phosphate and ammonia levels. Results were compiled to evaluate overall groundwater safety and identify areas of concern.

RESULTS

No organochlorines were detected in any of the samples, and all heavy metals complied with national drinking water standards. However, significant noncompliance was observed in other parameters. Microbial contamination was widespread, with 79.25% of samples failing to meet microbial standards due to the presence of fecal coliforms and Escherichia coli. Elevated levels of physical and nonmetal parameters were also noted, with 21 of 27 sites exceeding phosphate limits and 8 sites exceeding ammonia levels. These findings indicate substantial health risks associated with fecal contamination and nutrient pollution.

CONCLUSION

The PGHI project underscores the urgent need for enhanced groundwater treatment processes, regular monitoring, and strengthened policy-making to ensure safe drinking water. While the study provides critical insights, limitations such as lack of seasonal data, absence of emerging contaminant analysis, and limited spatial coverage highlight the necessity for continued improvements in groundwater management. Addressing these gaps is essential to protect public health, preserve environmental quality, and ensure the sustainable availability of safe groundwater for future generations.

Climate change is increasingly affecting public health and safety, disproportionately affecting vulnerable populations and aggravating existing health inequities. Recognizing the urgency of this challenge, the Department of Environmental and Occupational Health (EOH), College of Public Health, University of the Philippines Manila, convened the Seventh EOH Forum on November 21–22, 2024, with the theme Resilient Futures: Enhancing Health and Safety in Communities and Workplaces Amid Climate Challenges. This commentary highlights key points raised during the forum, with a focus on community-and workplace-level initiatives that address climate-related health risks. These efforts include the improvement of heat-health early warning systems, integration of climate resilience in occupational health and safety programs, and hospital-based interventions for environmental footprint reduction. The presentations also emphasized the need for multi-stakeholder collaboration, localized mitigation and adaptation strategies, and climate-informed health promotion activities. The forum highlighted that building resilient communities and workplaces requires not only policy alignment and institutional support but also interventions on the ground that are inclusive and equitable.

The Sixth Environmental and Occupational Health Forum, conducted virtually on November 23 to 24, 2023, focused on "Accelerating the Development of Healthy and climate-smart Hospitals in the Southeast Asian Region." This forum, a collaborative effort of the University of the Philippines Manila and Health Care Without Harm Southeast Asia, aimed to explore and exchange strategies, challenges, and innovative practices for integrating environmental sustainability in healthcare settings across Southeast Asia. The event gathered healthcare professionals, policymakers, and environmental experts to discuss the transformation of hospitals into health and climate-smart institutions. Keynote speakers from various countries presented case studies and research findings, emphasizing the need for holistic approaches that include policy development, stakeholder engagement, and continuous education. Significant outcomes highlighted were the identification of effective policies for sustainable hospitals, understanding the impact of healthcare facilities on climate change, and the necessity for political acumen in promoting environmental stewardship in healthcare. The forum concluded with a consensus on the critical need for ongoing collaboration and innovation in environmental and occupational health, underscoring the importance of transforming healthcare facilities into entities that prioritize both patient care and planetary health.
