The term environmental contaminants refers to harmful chemicals present in soil, in air, and in water.

These compounds may come directly from human sources such as industrial manufacturing. agricultural run-off, or wastewater discharge, or they may originate from natural sources, such as the taste and odor-causing chemicals in water generated by algae and bacteria blooms. 

Recent research has shown that a wide variety of such chemicals exist at trace concentrations in streams, lakes, rivers, and in groundwater throughout the world. 

A Growing List of Environmental Contaminants: 

  • Tate and odor-causing compounds (e.g. geosmin and MIB)
  • N-nitrosodimethylamine (NDMA)
  • Pharmaceuticals and personal care products (PPCPs) 
  • Pesticides and herbicides 
  • 1,4-Dioxane 
  • Fuels and fuel additives (e.g. MTBE and BTEX)
  • VOCs (e.g. PCE and TCE)
  • Endocrine disruptor  chemicals (EDCs)
  • Algal toxins (e.g. Microcystin)

These compounds can be treated either by UV light alone or by UV light in conjunction with hydrogen peroxide. 

Why UV for Environmental Contaminants? 

UV disinfection has been used successfully over the last century to disinfect drinking water and wastewater. That same technology is now applied to perform environmental contaminant treatment (ECT) on a large-scale. 


For certain contaminants, UV is the only economic method of treatment. For example, NDMA and 1,4-dioxane cannot be fully treated with membrane technologies (including reverse osmosis), carbon absorption, or air stripping. 

Eliminates Residuals 

UV has the advantage of being a destructive technology that breaks down a variety of contaminants into their safe, elemental components. 

Other treatment technologies merely transfer the contaminant from one phase to another (e.g. air stripping: from water to air) – resulting in a potentially hazardous, contaminant-laden residual that requires further treatment or disposal.
