Examples of where PFAS can be found include cleaners, textiles, leather, paper and paints, fire-fighting foams, and wire insulation.
    What is inside pfas are pesticides, stain resistant products, firelighting foams, microwave popcorn bags, eye makeup, pizza boxes, paints sealants and varnishes, cleaning products, nail polish, dental floss non stick cookware, water resistant clothing, shampoo, candy wrappers fast food packaging.
      What is the source of pfas Solid Waste Management Facilities. Industrial, commercial, and consumer products containing PFAS that have been disposed in municipal solid waste (MSW) landfills or other legacy disposal areas since the 1950s are potential sources of PFAS release to the environment.]]> 2022-09-09 22:15:27 UTC https://padlet.com/mwoo16/qhlmlgdigado6t4p/wish/2290304342 https://padlet.com/mwoo16/qhlmlgdigado6t4p/wish/2293146036 Gastrointestinal (GI) illness is caused by a variety of different disease-causing microbes or germs that can be acquired by consuming contaminated food or beverages, contact with contaminated recreational water, infected animals or their environments, or infected people. These germs can cause a variety of symptoms, such as diarrhea, nausea, vomiting, abdominal pain, abdominal cramps, fever and sometimes headaches, rash and paralysis.]]> 2022-09-12 21:33:29 UTC https://padlet.com/mwoo16/qhlmlgdigado6t4p/wish/2293146036 https://padlet.com/mwoo16/qhlmlgdigado6t4p/wish/2294786284 Nitrogen in wastewater is normally from the waste that is flushed the toilet.  When organic matter starts to decompose, it is done through the nitrification process. The biosolids in the wastewater then turn into ammonia, which in turns leads to an exertion of the BOD. Not only this but the presence of  ammonia in the water leads to Blue Baby Disease which isn't something we want as a society, it can be deadly and cause life long issues in people who have it as an infant. The good news is that this is most definitely preventable, and vigilant wastewater operators avoid this every day. ]]> 2022-09-13 17:10:06 UTC https://padlet.com/mwoo16/qhlmlgdigado6t4p/wish/2294786284 https://padlet.com/mwoo16/qhlmlgdigado6t4p/wish/2295260257 High concentrations of phosphorus may result from poor agricultural practices, runoff from urban areas and lawns, leaking septic systems, or did charges from sewage treatment plants.  Chemical precipitation is the process most often used to remove phosphorus from wastewater.  Iron and aluminum coagulants, sometimes calcium hydroxide or lime is used, are put in the wastewater during the sedimentation process and is called precipitation.

Branched alkylbenzene sulfonates (BAS) were popular in detergents but were replaced in the 1960s with Linear alkylbenzene sulfonates (LAS). BAS's were found to be a cause of foam in lakes and rivers. LAS's are still commonly used today. ]]> 2022-09-14 01:26:29 UTC https://padlet.com/mwoo16/qhlmlgdigado6t4p/wish/2295423636 https://padlet.com/mwoo16/qhlmlgdigado6t4p/wish/2295615976 Some examples of PCP are disinfectants, fragrances, insect repellants, and preservatives. They have a negative impact on the aquatic ecosystem, and have also been linked to endocrine disruption and reproductive disorders. There are about 70 recorded PCPs as emerging pollutants in 30 countries. They are not easily removed by conventional water treatment processes. ]]> 2022-09-14 03:56:59 UTC https://padlet.com/mwoo16/qhlmlgdigado6t4p/wish/2295615976 https://padlet.com/mwoo16/qhlmlgdigado6t4p/wish/2295658557
There are thousands of pharmaceuticals in use today. Some pharmaceuticals have been found in water and have raised concerns about the potential risks they pose to both humans and our ecosystems. These pharmaceuticals tend to make their way into our waters primarily through excretion of active drugs directly from patients and subsequent incomplete removal of those pharmaceuticals from our wastewater during wastewater treatment. ]]> 2022-09-14 04:39:11 UTC https://padlet.com/mwoo16/qhlmlgdigado6t4p/wish/2295658557 https://padlet.com/mwoo16/qhlmlgdigado6t4p/wish/2295763041 Too much Nitrate in the water can cause some serious problems. It allows blood to carry too much oxygen. You can get rid of Nitrates by reverse osmosis. Drinking water with high Nitrate levels can hurt newborn babies and cause Methemologlobinemia. High levels of Nitrate in drinking water most of the time comes from the run off farms that have used fertilizers. ]]> 2022-09-14 06:16:53 UTC https://padlet.com/mwoo16/qhlmlgdigado6t4p/wish/2295763041 https://padlet.com/mwoo16/qhlmlgdigado6t4p/wish/2297519197 Pesticides is the water that comes from the homes and it gets mixed together with the other water and some water might have different rent chemicals in them and it causes intended for the use for irrigation cause the water has mixture if substances.]]> 2022-09-15 03:43:11 UTC https://padlet.com/mwoo16/qhlmlgdigado6t4p/wish/2297519197 https://padlet.com/mwoo16/qhlmlgdigado6t4p/wish/2299039906 Benzyl chloride appears as a colorless liquid with a pungent odor. Toxic by inhalation and skin absorption. Flash point 153°F. Slightly soluble in water.  Corrosive to metals and tissue. Benzyl chloride is a member of the class of benzyl chlorides that is toluene substituted on the alpha-carbon  with chlorine .Benzyl chloride is used as a chemical intermediate in the manufacture of certain dyes and pharmaceutical products and as a photographic developer, petrol cleaner. The acute (short-term) effects of benzyl chloride from inhalation exposure in humans consist of severe irritation of the upper respiratory tract, skin, eyes, and mucous membranes, and lung damage along with pulmonary edema (fluid in lungs). Exposure to high concentrations also causes effects on the central nervous system (CNS). Animal data indicate that long- term exposure to benzyl chloride by gavage (placing it experimentally in the stomachs of mice) increased the incidence of benign and malignant tumors at multiple sites and resulted in a significant increase in thyroid tumors in female rats. EPA has classified benzyl chloride as a Group B2, probable human carcinogen. Exposure to Benzyl Chloride can occur if individuals come in to contact and inhale contaminated air, water or soil that has been exposed to Benzyl Chloride.]]> 2022-09-15 22:24:57 UTC https://padlet.com/mwoo16/qhlmlgdigado6t4p/wish/2299039906 https://padlet.com/mwoo16/qhlmlgdigado6t4p/wish/2387652920 is a silverish white metal  element that's radioactive, its found naturally in the environment through  water, rocks and soil ,  but in lower levels. When it occurs it rocks it can give off a very bright vibrant yellow color, most uranium that get into our waste water is through leaching in the environment from soil and water or higher level of uranium get into our waste water from nuclear radiation. uranium is mostly used to power nuclear power generation or even to make nuclear weapons. one example of how its gets into waste water other than the environment is through industrial waste water from mining . in the US the  mining industry obtains  uranium in two ways. The first is to mine rock that contains uranium. The second is to use a heavy chemical to dissolve uranium from underground rocks into ground water, and then pump the water to the surface. this process creates crazy high radioactive waste water that has to go through treatment process before it can be sent back into environment.
