Precautionary Principal in Water Pollution

The precautionary principle has become an essential framework in environmental law and policy,especially where scientific uncertainty and potential harm intersect. This research explores theapplication of the precautionary principle in the context of water pollution management. It investigateshow governments and regulatory bodies adopt this principle in decision-making processes,particularly in the face of emerging contaminants such as microplastics, pharmaceuticals, and PFAS("forever chemicals"). The paper evaluates legal frameworks, scientific thresholds, and case studiesfrom the EU, United States, and Global South to understand how precautionary measures areinterpreted and enforced. It further identifies institutional, economic, and political barriers to effectiveimplementation and proposes policy recommendations to enhance precaution-based water protectionmechanisms globally.
