Water Quality, Chemistry, And Hydrology Of Salt Creek In Northeastern Illinois, Luke Lampo

Celebration of Learning

Salt Creek flows through the metropolitan area of Chicago and into the Des Plaines River. Its urban environment provides multiple sources of contamination, including storm runoff, combined sewer overflow, and wastewater treatment plant discharge. The purpose of this study is to determine how water chemistry changes downstream, whether the presence and levels of metals meet IPCB (Illinois Pollution Control Board) and EPA (Environmental Protection Agency) water quality standards, and how water chemistry changes during periods of storm flow and base flow. The study area consists of 10 sites along a 37 km stretch of Salt Creek. Water samples were taken …

Geochemical Analysis Of Surface Materials Surrounding The Bautsch-Gray Mine Superfund Site Near Galena, Illinois, Ryan Plath

Celebration of Learning

The Bautsch-Gray zinc and lead mine, near Galena, Ill., was in operation from the early 1900s until closing in 1975. The mine’s tailings pile has documented elevated lead and zinc concentrations in the surface materials surrounding the site. Numerous floods have caused contaminated sediment to migrate off the mine tailings pile, across Blackjack Road and into an outwash basin, and towards Smallpox Creek. Since this site was designated an EPA priority list superfund site in 2010, there have been numerous remediation efforts.

This study attempts to develop a better understanding of the contamination within the soils of the outwash basin …

On The Sum Of The Reciprocals Of Squares, Hussam Ibrahim

Celebration of Learning

The Fourier Series has always been a great tool by turning the most complicated functions into a simple approximation by several sine and cosine terms. However, given the fact that its called an approximation arouses the question of how accurate is this approximation, especially with functions that have a corner at x values. In this project, we will show how the series that is the sum of the reciprocals of squares arises in the study of Fourier series. We will discuss the convergence and the rate of convergence of this series. This result arose during exploration on mathematical software Sage. …
