HEXACHLOROBENZENE
Parameter Type: Drinking Water Testing for Volatiles
Parameter Name: Hexachlorobenzene
What it is and Where it Comes From:
Hexachlorobenzene (HCB) is a fungicide and is an organochloride with the molecular formula C6Cl6. It was formerly used as a seed treatment, especially on wheat to control the fungal disease bunt. It has been banned globally under the Stockholm Convention on Persistent Organic Pollutants. Although Hexachlorobenzene HCB is not readily leached from soils and sediments, some desorption does occur and may be a continuous source of Hexachlorobenzene HCB to the environment, even if inputs to the system cease. Drinking water testing gives you several benefits like peace of mind, identifying contaminants in your water, and insight into health concerns. Safe Home offers Laboratory drinking water testing kits for hexachlorobenzene, allowing you to collect your water sample and ship it directly to our EPA-Certified Laboratory. This platform of drinking water testing for hexachlorobenzene will give you an accurate level based on the lowest level of a parameter our instruments can detect (Method Detection Level). Safe Home drinking water testing for semi-volatiles can be used for city and well water supplies. Drinking water testing should be done any time you notice a significant change in your water quality.
Health Effects:
Chronic (long-term) oral exposure to hexachlorobenzene in humans results in a liver disease with associated skin lesions. Epidemiologic studies of persons orally exposed to hexachlorobenzene have not shown an increased cancer incidence. However, based on animal studies that have reported cancer of the liver, thyroid, and kidney from oral exposure to hexachlorobenzene, EPA has classified hexachlorobenzene as a probable human carcinogen (Group B2). High or repeated exposure may damage the nervous system and can cause irritability, difficulty with walking and coordination, muscle weakness, tremors, seizures and/or a feeling of “pins and needles” on the skin. Acute animal tests in rats and mice have shown hexachlorobenzene to have low-to-moderate acute toxicity from oral exposure.
Solutions to Contaminant Levels:
What are the next steps after drinking water testing? The best available treatment technology for removing Hexachlorobenzene is granular activated carbon filtration system. A filter with granular activated carbon (GAC) is a proven option to remove certain chemicals, particularly organic chemicals, from water. Activated carbon is a porous material that removes organic compounds from liquids and gases by a process known as “adsorption.” In adsorption, organic molecules contained in a liquid or gas are attracted and bound to the surface of the pores of the activated carbon as the liquid or gas is passed through. Adsorption occurs on the internal surface of activated carbon, termed the adsorbent. During adsorption, liquids or gases pass through the highly porous structure of the activated carbon. The compound(s) to be removed, termed the adsorbate(s), diffuses to the surface of the adsorbent, and is retained because of attractive forces. The primary raw material used in the production of our activated carbons is bituminous coal that is crushed, sized, and processed in low temperature bakers followed by high-temperature activation furnaces. Activation develops the pore structure of the carbon. Through adjustments in the activation process, differentiated pores for a particular purification application are developed. It is recommended to test your drinking water every one to two years. Who do I need to contact to find out more information about water quality in my area? Every community water supplier must provide an annual report to its customers, known as a Consumer Confidence Report (CCR). The report provides information on your local drinking water quality, including the water’s source, contaminants found in the water, and how consumers can get involved in protecting drinking water. How often does the local public water system preform drinking water testing? Frequency of drinking water testing depends on the number of people served, the type of water source, and types of contaminants. Certain contaminants are tested more frequently than others, as established by the Safe Drinking Water Act. You can find out about levels of regulated contaminants in your treated water for the previous calendar year in your annual Consumer Confidence Report (CCR).
