The causes of water pollution include a wide range of chemicals and pathogens as well as physical parameters. The technology is based on the cobalt-mediated decomposition of peroxymonosulfate that leads to the formation of very strong oxidizing species (sulfate radicals) in the aqueous phase. The following table shows the primary and secondary water contaminants, divided in inorganic and organic elements. Natural Organic Matter (NOM). Persistent organic pollutants (POPs), sometimes known as "forever chemicals" are organic compounds that are resistant to environmental degradation through chemical, biological, and photolytic processes. Of particular concern are emerging organic contaminants (EOCs), the term used not only to cover newly developed compounds but also compounds newly discovered as contaminants in the environment. There are hundreds of thousands of SOCs. Microbial and organic contaminants can’t always be detected by a human's vision, sense of smell or taste. Organic Contaminants Testing in Vermont The Vermont Department of Health Laboratory (VDHL) has the ability to analyze drinking water samples for multiple chemical contaminants. Developed specifically for drinking water applications, the fixed-bed treatment process consistently addresses contaminants at low levels, with intermittent or fixed operation. Total organic carbon, or TOC, is the measurement of organic, carbon-based contaminants in water. Typically, the problem only comes to light once people begin to get sick. Some occur as a result of manmade pollution such as perchlorate, and others like nitrates occur because of interactions between nature and pollution. If these compounds are improperly disposed, they can easily seep into both groundwater and surface water supplies. Right? Byproducts of Disinfection (BODs) also referred to as Disinfection Byproducts. Researchers at Cranfield are seeking to better understand removal technologies and investigate nature-based solutions for emerging organic pollutants.
