In April 1901, the
Guggenheim family gained control of the company, and in 1905, bought the Tacoma smelter from the
Bunker Hill Mining Company. ASARCO eventually controlled 90% of the U.S. lead production, essentially becoming a smelter
trust.
On January 11, 1916, sixteen ASARCO employees
were killed and mutilated by
Pancho Villa

Litigation history

After the Colorado Department of Public Health and Environment sued ASARCO for damages to natural resources in 1983, the
EPA placed the ASARCO Globe Plant on its National Priorities List of Superfund sites, with ASARCO to pay for the site's cleanup.
In 1972 ASARCO's downtown Omaha plant in Nebraska was found to be releasing high amounts of lead into the air and ground surrounding the plant. In 1995 ASARCO submitted a demolition and site cleanup plan to the Nebraska Department of Environmental Quality for their impact on the local residential area. Fined $3.6 million in 1996 for discharging lead and other pollutants into the
Missouri River
The Missouri River is a river in the Central United States, Central and Mountain states, Mountain West regions of the United States. The nation's longest, it rises in the eastern Centennial Mountains of the Bitterroot Range of the Rocky Moun ...
, ASARCO closed its Omaha plant in July 1997. After extensive site cleanup, the land was turned over to the
City of Omaha as a park. All of
East Omaha, comprising more than 8,000 acres (32 km
2), was declared a Superfund site. As of 2003, 290 acres (1.2 km
2) had been cleaned.
In 1991 the
Coeur d'Alene Tribe
The Coeur d'Alene Tribe ( ; also Skitswish; ) are a Native American tribe and one of five federally recognized tribes in the state of Idaho. The Coeur d'Alene have sovereign control of their Coeur d'Alene Reservation, which includes a significa ...
filed suit under
CERCLA against Hecla Mining Company, ASARCO and other defendants for damages and cleanup costs downstream of what has been designated as the
Bunker Hill Mine and Smelting Complex Superfund site. Contamination had affected Lake Coeur d'Alene and the Saint Joe River, as well as related waters and lands, and cleanup had been under way since the early 1980s. In 1996 the United States joined the suit. In 2008 after emerging from bankruptcy, ASARCO LLC settled for $452 million for contributions to this site.

''The Spokesman,'' 14 June 2011; accessed 31 May 2016["Hecla Mining Company to Pay $263 Million in Settlement to Resolve Idaho Superfund Site Litigation and Foster Cooperation"](_blank)
Press release, US Department of Justice, 13 June 2011; accessed 31 May 2016 This was part of a nearly $2 billion settlement (see below) with the US for a total of 26 sites.

In 2007, the Environmental Protection Agency released the results of soil and air tests in
Hayden, Arizona, taken adjacent to the ASARCO Hayden Smelter. The results showed abnormally high amounts of pollutants that violate prescribed health standards. Arsenic, lead and copper were among the most egregious pollutants found in Hayden. As a consequence of the contamination, the EPA proposed to add Hayden, Arizona, to the list of Federal Superfund sites. This action would provide funding to clean up the contamination. ASARCO fought the action, supported by Democratic Gov.
Janet Napolitano, who said: "I am asking that the EPA delay final decision on listing until March 31, 2008. This would provide ample time for the EPA, in close coordination with ADEQ, to enter an agreement with ASARCO to conduct remedial actions..." After emerging from Chapter 11 bankruptcy in 2008, ASARCO made a settlement with the government of $1.79 billion for contamination at various sites; the funds were allotted to the
Environmental Protection Agency (EPA) for cleanup at 26 sites around the country.
A final settlement for $1.79 billion was made in 2009 for up 80 sites, including one of the most notorious, the smelting plant at
El Paso, Texas
El Paso (; ; or ) is a city in and the county seat of El Paso County, Texas, United States. The 2020 United States census, 2020 population of the city from the United States Census Bureau, U.S. Census Bureau was 678,815, making it the List of ...

ASARCO's
Tar Creek Superfund site was the subject of the film documentary ''
Tar Creek'' (2009), made by Matt Myers. At one time, Tar Creek was considered to be the worst environmental problem on the EPA's list of more than 1200 sites.
