This is a list of Superfund sites in Indiana designated under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) environmental law. The CERCLA federal law of 1980 authorized the United States Environmental Protection Agency (EPA) to create a list of polluted locations requiring a long-term response to clean up hazardous material contaminations.

Clinical and toxicological research conducted on volcanic crystalline silica has found little to no evidence of its ability to cause silicosis/pneumoconiosis-like diseases and geochemical analyses have shown that there are inherent factors in the crystalline structure which may render volcanic crystalline silica much less pathogenic than some ...
A video discussing a field-based approach to silica monitoring. Monitoring could help reduce exposure to silica. Using the Hierarchy of Controls, there are various methods of preventing exposure to respirable crystalline silica. The best way to prevent silicosis is to avoid worker exposure to dust containing respirable crystalline silica. [24]
National Oceanographic Data Center (NODC), which includes the National Coastal Data Development Center (NCDDC) NCEI was established by the Consolidated and Further Continuing Appropriations Act, 2015, Public Law 113-235 in response to increasing demand for environmental information.
Friability testing is a laboratory technique used by the pharmaceutical industry to test the durability of tablets during transit. This testing involves repeatedly dropping a sample of tablets over a fixed time, using a rotating wheel with a baffle.
The first part of the process is to create the colloid precursor which consists of the silica nanoparticles and the solvent. The initial silica nanoparticles are in an amorphous crystalline phase and the solvent is composed of trimethylsilyl chloride (TMCS) and ethyl alcohol. To synthesize hydrophobic nanostructured silica using this method ...
Kaolinite (/ ˈ k eɪ. ə l ə ˌ n aɪ t,-l ɪ-/ KAY-ə-lə-nyte, -lih-; also called kaolin) [5] [6] [7] is a clay mineral, with the chemical composition Al 2 Si 2 O 5 4.It is a layered silicate mineral, with one tetrahedral sheet of silica (SiO 4) linked through oxygen atoms to one octahedral sheet of alumina (AlO 6).
Ascension St. Vincent Evansville (formerly St. Mary's Hospital and Medical Center) is the flagship hospital of a health system in the Illinois–Indiana–Kentucky tri-state area located in Evansville, Indiana and is a level II trauma center. The system was started in 1872 and was formerly known as St. Mary's Health. St.
