In 1887, Robert Towne built a metals smelter two and a half miles northwest of El Paso, Texas, across the river from Ciudad Juarez in Mexico and across the state border from several small towns in New Mexico. The smelter, which processed metal ore from regional mines, was quickly acquired by ASARCO (American Smelting and Refining Company) and became an important visual and economic institution in the region. In 1967, following the mantra of environmental regulation at the time—"the solution to pollution is dilution"—ASARCO erected what was then the tallest smokestack in the world: an 828-foot structure visible from much of the region. While the facility provided jobs to many in the region and produced metals important for a range of manufacturing and consumer products, by the 1970s, residents and scientists began to question the other products from the smelter—especially heavy metals pollution.

On September 10, 2012, several million southern California residents reacted with alarm to an unfamiliar noxious scent. The Air Quality Management District officials in the Los Angeles region were initially at a loss to determine the odor's source. Investigators from Ventura to Palm Springs looked for toxic spills, sewage plant leaks, and gas line breaks—all for naught.

The smell's origin was the Salton Sea more than 150 miles away and not usually upwind. The smell of an algal bloom and subsequent massive fish kill released odor molecules redolent with the stench of environmental decay.

This case study is an examination of the chemical and sensory impacts of a variety of environmental issues including sand mining, leaking underground gasoline storage tanks (LUSTs), and a railroad.

Wedron is a small, unincorporated town of approximately 100 residents in north central Illinois. A large sand mine has been in operation on the south and west sides of the town for many decades, and the mine property includes several abandoned and active pits, a processing plant, and a train car loading facility. Railroad tracks are located along the east side of town as is a grain elevator (storage and loading facility).

The following information was obtained from the US EPA web site about Wedron, personal visits to the town, and published news articles.

This Western Mining History database uses Mineral Resources Data System to list known Colorado historical mines by county. Each county site has links to the known mines within its borders. Some are known and named, others are unnamed. Mines should be assumed to be on private property unless other research is conducted. Data provided for each mine site include: Name, State, County, Elevation, Primary Mineral Mined, Latitude and Longitude and a link to Google Maps. Photos are provided where available. Additional information for some Mines are satellite photos, and ownership, business and historical records. Mining History is an historical site that provides information on mining, mining towns, the gold and silver rush, and Photos and maps of the western United States.

Students read A Chair for My Mother, about a little girl and her family who save money to buy a chair after their furniture is destroyed in a fire. Students learn that characters in the book are human resources who save part of the income they earn. Students identify other human resources, discuss how their work allows them to earn income and name strategies that will help them reach a savings goal. (Book written by Vera B. Williams / ISBN: 068804074-8)

The 20th century ushered in a change from handcrafting to machine tooling. Henry Ford introduced one of the first moving assembly lines as a way to turn out more cars more quickly, and the emerging auto industry popularized this mode. A photo of the Doble Steam Motors Corporation factory shows a line of workers and car chassis in production. This new technology, and the spread of industrialization, changed forever the way that work was completed. A wide variety of industries all across the country converted to mechanization, and California was no exception. One 1929 image shows young women working in a towel factory in Orange. Photographs taken in San Francisco illustrate that workers used machines to make products as different as Ghirardelli Chocolate and music rolls for automated player pianos. Images also show women working on an assembly line in a soap factory, and men sewing clothes in a shop (at a time when a good suit, cut on machines instead of by hand, retailed for $40 to $50). Automation and mechanization also changed agricultural practices. The combined traction steam harvester built by Stockton J. Barry on his California ranch was one of the machines that changed the way produce was harvested. Mechanized canning changed the way fruit and vegetables were processed and preserved, and made out-of-season produce available year round. Photographs in this group show cannery workers at tables, and cans going through a labeling machine. The introduction of mechanized food processing eventually brought a new awareness of the importance of standards for foods production. The Pure Food and Drug Act and the Meat Inspection Act were both passed in 1906. As workers nationwide adjusted to an increasingly mechanized workplace, good working conditions took on new importance. Workers in several industries formed unions (such as the Berryessa Fruit Growers formed in 1920, shown here) to promote safer working conditions and limit maximum working hours.
