Wastewater

generation: The wastewater produced during the chemical processes contains high concentration of chemicals such as bisulfites, sodium carbonate, sodium hydroxide, sodium sulfide, chlorine dioxide, hydrochloric acid, calcium oxide etc which is potentially unsafe to purge directly into the environment. Sludge by waste water treatment: The significant solid wastes such as lime mud, lime slaker grits, green liquor dregs, boiler and furnace ash, scrubber sludges, wood processing residuals and…

Yet, out of 30,000 wastewater disposal wells only a small fraction appear to be problematic (Ellsworth 2013). This could be due to the amount of water (volume) injected into the wells at the time or whether the pressure is directly communicated into basement faults (Ellsworth 2013). Injection induced earthquakes are clearly a reason for concern as they present a seismic hazard. Industrial activity has for a long period of time been a known cause for earthquakes, impoundment of reservoirs,…

Suspended particles from wastewater releases can reduce the amount of sunlight penetrating the water; thus, disrupting the growth of photosynthetic plants and microorganisms (NRDC, 2016). Additionally, increased urbanization and agriculture can increase the presence of organic matter…

ideas about birth control and waterways, they included: wastewater plants cannot remove EE2, study on fish, and dilemma how birth control affects waterways. These ideas are essentially the same because they all talk about how EE2 is harmful to wildlife in waterways. One article explains an experiment conducted on fish and how they react to EE2 and/if they reproduce. Since birth control had high estrogen levels, EE2 gets into water and wastewater plants cannot remove EE2 because of the…

Some of the many chemicals that are polluting the Chesapeake Bay are polychlorinated biphenyls (PBCs), polycyclic aromatic hydrocarbons (PAHs), pesticides, and personal care/pharmaceutical products. PBCs are a flame retardant that cannot legally be made in the USA, but are legally imported and pollute the bay about evenly throughout. When gas, oil, or coal is burned, PAHs can be formed. PAHs are found mostly around Baltimore and near the Anacostia and Elizabeth rivers. Since agriculture is…

is contained or limited to the environment. On example of Site restriction is Wellhead Wastewater Treatment that uses the wastewater from fracking to be “inserted deep a well which … Effectively, the fracking process is pushing the water down into the rock formation, trying to wedge the rock cracks open. The sand fills in between the cracks that the hydraulic fluid has propped open” (Easton). Wellhead Wastewater Treatment is the use of already contaminated water into specified wells that have…

Cost of Water in Rural China Water is one of the most undervalued resources that are essential to human beings, industries and agriculture. Safe water is also one of the biggest issues that our world face today. Technology has made water access as easy as turning on the tap water and press of a button to flash the toilet. According to the U.S. Geological Survey (2014), each person uses about 80-100 gallons of water per day. Estimation may vary depends on geographic location, but no matter where…

Last week we worked on ocean currents. We worked on a lot of things about water pollution. We went over things about acid rain, we went over stuff about sewage and wastewater, we went over stuff about industrial waste. Also during this week we went over oil pollution, eutrophication, radioactive waste, marine dumping, and also underground storage leaks. We all split into groups and made a presentation about one of them. After that we made a google document about a reflection on the presentations…

to extreme weather events, changing water flow and human impacts. A 2011-2015 study on the water quality dynamics of Oso Bay found fluctuations in the estuarine geochemistry were related to some of these factors, particularly human influences. A wastewater affluent region in Oso Bay showed very high concentrations of Inorganic and organic nitrogen, phosphate, and carbon; it also showed a low concentration of dissolved oxygen, chlorophyll, and a more acidic pH (Wtz, et al. 2015). Signatures of…
