Goa Wetlands: Harvard Students Test Fungal-Plant Clean Water Tech
7 Sep
Summary
- Harvard students are testing modular wetland ecosystems in Goa.
- These BioPods use fungal mycelium and native plants to clean water.
- The system is designed for degraded urban waterways, not pristine ones.
Harvard University students are investigating potential pilot locations in Goa to deploy their BioPod system, a novel approach to water purification. This nature-based solution integrates fungal mycelium with native wetland flora to effectively remove pollutants from contaminated water bodies.
The BioPod technology, successfully tested previously in Rhode Island, USA, offers a customizable design capable of addressing diverse contaminants and specific ecological conditions. The students' focus is on remediating degraded urban waterways that have suffered significant ecological damage from pollution, rather than impacting healthier wetland areas.
Avantika Velho, one of the students, highlighted the system's adaptability to various pollutants, including agricultural runoff, heavy metals, and oil. She explained that once a mycelium mat is established, native plants like cattail and vetiver grass are introduced. This combined fungal and plant structure works synergistically, with mycelium secreting enzymes to break down pollutants and plant roots absorbing contaminants.
Pradip Sarmokadam of the Goa State Biodiversity Board expressed support for the proposal but underscored the importance of rigorous pilot-scale assessments. He recommended evaluating the BioPod's performance and any potential unintended biological effects before considering broader implementation in Goa's wetlands.
