I'm interested in better understanding the ongoing geological processes that shape St. Louis and the Mississippi Valley region. So far, I've been looking into the history of seismicity in the region, focusing on the fascinating but little known history of the New Madrid earthquakes of 1811 and 1812 -- the most devastating earthquakes to have hit the US east of the Rockies. I've also been exploring how St. Louis and surrounding areas are dealing with the possibility of another earthquake occurring in the future. According to one article I read, one of the biggest uncertainties is what would happen to the heavily engineered Mississippi River in the case of another major tremblor. The shaking could break the levees, flooding wide areas along the river and creating cascading effects. The flow of the river might also reverse completely, as occurred during the New Madrid earthquakes.

On these possibilities and the lack of scientific consensus surrounding intraplate seismicity in this zone, see this article in The Atlantic.

On current efforts to create earthquake hazard maps in St. Louis, see this overview on the US Geological Survey site.

For a deeper dive into the history of the New Madrid earthquakes, see this book by historian of science Conevery Bolton Valencius. 

Air pollution has been a problem within Newark due to it being surrounded by industries and constantly being driven through by motor vehicles. This report is relevant to air pollution in Newark because the problems and possible solutions to air pollution presented in this report can be applied to Newark's air pollution problem

For reducing air pollution, the article suggested decreasing gas usage by walking, riding a bike, or taking public transportation. The article also suggested choosing a car with better miles per gallon or using an electric car.

The article informs its readers that there is an excess amount of lead in Newark's drinking water as of September 20, 2017. Five addresses had the tap water tested and the lead levels exceeded at least three times the federal standard and Newark's Water Department was informed. The article then explains the process at which Newark's Water Department must go through in response to the excess amount of lead and what residents must do.

To help the government with air pollution, people can try to use their cars less. This can be done through walking, biking, or carpooling to their destinations. This will help lessen the usage of fossil fuels that decrease the air quality. Although this may not seem like much, if more and more people begin to do this, eventually the results will begin to show

Newark is considered an ironbound community because it is surrounded by industry all around it. Because of this, this leads to an increase in air pollution. On top of all that, the many roads that lead through Newark carry the harmful gases that pollute the air

Yes and no. Communities should be able to do something about their air quality in their area but within the state's command. For example, states should have a state regulation on air quality and be able to enforce that regulation. However, individual communities should be able to do what they want to meet that state regulation on air quality. With this, communities still have the freedom to do something about their air quality while the state maintains its power

EPA is collecting data about the air quality in the ironbound communities. This data is used to find what causes the air pollution and EPA is working to fix the problem and improve the overall health of the communities

Officials are looking to change something like the trucks within the port industry in Newark to counteract air pollution while keeping in mind the jobs of many who can be affected by the changes. The port of New York and New Jersey supplies 270,000 jobs and $36 billion in economic activity for shipping. If the possible changes were implemented, they must make sure that this industry is not impacted negatively because that can hurt the communities connected to the industry.
