1941 - Basic Magnesium Inc. (BMI) was built by the Anaconda Copper Company for the Federal Government to produce magnesium - the lightest and strongest of metals - that was suddenly needed in large supply to build airplane bodies and other materials critical to the Allied effort during World War II.

1941 - 1942 - Heroic labor of 13,000 workers and at a cost of over $130 million, Basic Magnesium Inc. produced magnesium ingots to support the Allied war effort.

1944 - Having met the production requirement of magnesium for the war effort, the plant was shut down by the United States Government in 1944.

1947 - Nevada Senator Pat McCarran convinced Congress to allow Nevada to purchase the plant for $24 million. The terms included a $1 down payment, with the balance to be paid from leasing the facilities to private industries.

1952 - The magnesium plant was divided and privatized by Nevada, which sold various production facilities to several leading American manufacturers. They created Basic Management Inc. as a separate cooperative to own and manage  utilities, such as water and power, within the industrial complex and for other users including the State of Nevada, Las Vegas, and Henderson. Basic Management Inc. still delivers water from Lake Mead to the State and Henderson.  Remarkably, Basic Management Inc. has never missed a day's delivery.

1953 - City of Henderson was incorporated.

1950s, 1960s, 1970s - Several chemical and metal manufacturers (and the US Navy)continued to use the Basic Magnesium production facilities.

1976
- The use of unlined, evaporation and percolation ponds on the site were permanently discontinued. TIMET, a titanium manufacturer, built a smaller series of lined evaporation ponds under permits issued by the Nevada Division of Environmental Protection.

1991
- Six current and former companies at the Basic Management Inc. complex formed the Henderson Industrial Site Steering Committee(HISSC) to voluntarily enter into an agreement with the Nevada Division of Environmental Protection (NDEP). The purpose of the agreement is to implement a multiphased approach to assess and remediate properties contaminated by historic (and legal at the time) waste-disposal practices.

1999
- Basic Remediation Company was formed under Basic Management, Inc. to serve as the remediation contractor for this site.

1999
- BMI negotiated with the Henderson Industrial Site Steering Committee(HISSC) members to take over the remedial activities of the site, enabling Basic Management, Inc. as the landowner, to perform the restoration of its property.

2005
- LandWell funded a water treatment facility on TIMET's manufacturing plant site to process TIMET's effluent. This allowed TIMET to permanently discontinue its permitted use of its lined permitted evaporation ponds. LandWell gained control of the area and began drying the material in the lined TIMET ponds in preparation for excavation and transportation to the approved Corrective Action Management Unit (CAMU).

Feb. 2006
- Final voluntary agreement was reached among the NDEP and current and former land owners and manufacturers at the Basic Magnesium complex.  Set forth the legal/framework by which to carry out the remediation process.

Sept. 2006
- Corrective Action Plan approved by NDEP, which details the physical remediation process.

Nov. 2006
- Dedication of The LandWell Restoration Project Community Information Center.

July 2007
- NDEP approves the plan for the Corrective Action Management Unit (CAMU). 

August 2007 - Henderson Planning Commission approves LandWell's development agreement.   Construction on the modern CAMU begins soil excavation

October 2007 - NDEP and the Henderson City Council approve the Closure Plan, which is the key planning document needed to begin remediating the site.

February 2008 - The LandWell Company selects ENTACT Environmental to lead the remediation efforts on the 2,200 acres of land. 

March 2008 -  Remediation pilot project began.

June 2008 - Commenced final grading on the CAMU Phase I.

July 2008 - Installation of CAMU Phase I liner.

August 2008 - Excavation and transportation of contaminated soil begins
