Water Security: Blueprint
This page outlines the strategy for water infrastructure, public health, and policy solutions to ensure safe, resilient water systems.
Water Infrastructure & Public Health
Targeted investments in treatment, pipe replacement, and monitoring reduce contamination risks and protect communities.

Nanoparticle Remediation Options
| Nanoparticle Type | Primary Function & Targets | Key Consideration |
|---|---|---|
| Zero-Valent Iron (nZVI) | Reductive destruction of chlorinated solvents; heavy metal immobilization | Good for groundwater remediation; can oxidize over time |
| Titanium Dioxide (TiO2) | Photocatalytic degradation of organics using light energy | Requires UV; research on visible-light activation |
| Silver (Ag NPs) | Antimicrobial activity vs bacteria and pathogens | Effective size/shape dependent; environmental fate concerns |
| Carbon-Based (Graphene Oxide) | High-capacity adsorption of heavy metals and organics | High surface area; can be functionalized for targets |
Product Tiers
| Product Tier | Target User | Proposed Technology | Added Benefit |
|---|---|---|---|
| Personal (Portable Purifier) | Travelers, emergency preparedness | Multi-stage: pre-filter + carbon + hollow-fiber (0.01µm) + optional electrochemical | Safe rinsing of produce; emergency drinking water |
| Home (Point-of-Entry) | Households with contaminated tap water | Sediment + catalytic carbon + ion-exchange + UV-C LED; smart monitoring | Whole-house protection for cooking and irrigation |
| Municipal (Advanced Module) | Treatment plants & ag co-ops | Ultrafiltration + fixed-film bioreactor + AI monitoring | Polished reclaimed water safe for irrigation |
