  • WQA Offers Drinking Water Resources for Hurricanes


    Flood resources, including a video called “Five Things to Know About Water After a Flood,” are available from the Water Quality Association to help ensure a safer water supply during severe flooding expected in Florida and Georgia when Hurricane Ian makes landfall Wednesday. The storm, which on Tuesday was a Category 3 hurricane with 120 mph winds, is expected to strengthen overnight Tuesday and create heavy rains and flooding when it hits the Tampa Bay and Fort Meyers areas Wednesday. The governors of both Florida and George have declared states of emergency, and more than 2.5 million Floridians are under evacuation order.

  • Boil Water Notice Study


    Treatment for microbial contamination may be applied either where the water enters the home (point of entry) or at the point where drinking water is drawn (point of use). Consumers may boil their water or install a point-of-use or point-of-entry water treatment system certified for total microbial (e.g., bacteria, viruses and protozoa) reduction. If you have a POU or POE treatment system already in place that uses carbon, some other media, or a membrane for the reduction of chemicals or particulate contaminants of concern, be sure to consult the owner’s manual or a local water professional to determine how the system should be safely serviced, cleaned and sanitized prior to reuse. 

  • Flooding Precautions Fact Sheet


    Water may not be safe to drink, cook or clean with after an emergency such as a flood. During and after flooding, water can become contaminated with  microorganisms such as bacteria, sewage, heating oil, agricultural or industrial waste, chemicals and other substances that can cause serious illness. People with private drinking water wells in flooded areas can take precautions and […]

  • Manganese Fact Sheet


    Manganese is a mineral that is found naturally in the environment and is one of the most abundant metals on the earth’s surface, in air, water, and soil. It can be found in both groundwater and surface water from natural sources or as a result of human activity such as mining and industrial discharges.   Manganese is used in various industries, including the manufacture of iron and steel alloys, batteries, glass, fireworks, various cleaning supplies, fertilizers, varnish, fungicides, cosmetics, and livestock feeding supplements.

  • Flouride Fact Sheet


    Fluorine is a natural trace element and exists in almost all soils. Fluoride is classified as any binary compound of fluorine with another element. Perhaps the most widely known use of fluoride is its addition to public drinking water supplies at about one milligram per liter (mg/L) of a fluoride salt, measured as fluoride, for the purpose of reducing tooth decay. 

  • Uranium Fact Sheet


    Uranium is a common naturally occurring and radioactive substance. It is a normal part of rocks, soil, air and water. Uranium occurs in nature in the form of minerals, but never as a metal. Uranium enters water by leaching from soil and rocks, or in releases from processing plants. Uranium has demonstrated toxic effects on human kidneys leading to their inflammation and changes in urine composition. Uranium can decay into other radioactive substances, such as radium, which can cause cancer with extensive exposure over a long period of time (U.S. EPA, 2013).

  • Pharmaceuticals, Personal Care Products and Endocrine Disrupting Compounds


    The presence of pharmaceuticals, personal care products and endocrine disrupting chemicals (PPCP/EDC) in water supplies has been known for many years, dating back to the 1980’s and before. Much of the original concerns were associated with reports of physiological abnormalities associated with fish and other aquatic organisms in areas near or surrounding discharge sites of wastewater treatment facilities. Over time the concerns associated with wastewater effluent have expanded into the drinking water arena. These concerns are further heightened as a result of periodic media reports, or other reports reaffirming the presence of these compounds, albeit at trace levels, in drinking water source waters or finished drinking water supplies.

  • Granular Activated Carbon (GAC) Fact Sheet


    The use of granular activated carbon (GAC) for water purification became common around the start of the 20th century (1906) when the “activation” process was applied to charcoal (which had been used for centuries). Thermal activation of charcoal greatly improves its pore volume, surface area and structure making it a superb workhorse for water treatment.

  • Ion Exchange Fact Sheet


    Water is the universal solvent that is able to dissolve a little bit of everything it touches. It could, therefore, be said that “pure” water does not exist. Even the most highly processed and purified water still contains trace levels of gases, salts or minerals that have been leached from its containment vessel or absorbed from the surrounding air. Salts are formed naturally when acidic rain water is neutralized by alkaline soil strata. Common salt (also called table salt) is sodium chloride (NaCl), but salt also refers to compounds containing potassium (K), calcium (Ca), iron (Fe), carbonates (CO32-), nitrates (NO31-) and many other combinations of elements.
