TL;DR: In this paper, street sediment samples were dry sieved into four different particle size categories and a sequential extraction procedure was done on each size category following the methodology proposed by Tessier et al. 1979 using a Hitachi 180-80 Polarized Zeeman Atomic Absorption Spectrophotometer.

TL;DR: In this paper, a combination of sampling and mathematical modeling was used to characterize both CSO and receiving water quality in the city of Buffalo, New York, and the results showed that while CSOs within the city boundary are a source of fecal coliform to the Buffalo River, higher concentrations enter the river from the upper watershed upstream of the city.

TL;DR: This work studied the current distribution and population densities of Popenaias popeii endemic to the Rio Grande drainage in Texas, and developed a method to evaluate changes in the population’s size and distributional range over the last 100 years.

TL;DR: In this paper, two kriging models were used to analyze surface and subsurface sediment contamination in the Buffalo River, and the results indicated that additional removal of contaminated sediments may need to be considered where no dredging has occurred or is not currently planned.

TL;DR: In this article, the authors used sediment core data to model the geographic distribution of mercury within surface and subsurface sediments of a section of the Buffalo River Area of Concern (AOC).
