“…It is a process that lasts for many years [Vangelas et al 2006], but if it happens in such a way as before, the increasingly polluted leaching will have less and less impact on groundwater. A good example of this includes the areas of the former Cracow Soda Works Solvay, which was closed in 1990.…”

The "Soda Mątwy" plant in Inowrocław produces light and heavy soda ash by means of the Solvay method, and the production process is associated with the formation of highly saline waste, which can adversely affect all elements of the environment. In view of the existing threats, attempts are undertaken to limit the quantity and improve the quality of post-production sewage. The aim of the study is to determine the effectiveness of activities to protect the water in the area of the soda production plant in Inowrocław. The assessment of their effectiveness was based on the analysis of the current level of chloride concentration reduction at 4 measurement points around the plant and determination of the trend for further changes. In all piezometers, the concentration of chloride ions has decreased and showed the same tendency in subsequent years, which allows draw conclusions confirming high effectiveness of the activities related to water protection.

“…Ion concentrations, the indirect measure of which is EC, are still very high in the waste forming the heap. The process of leaching them from the aeration zone of soils is very slow [5,31]. This is why they will be a source of pollution of the surrounding lands and groundwater for many more years.…”

The aim of the work was to determine whether the waste accumulated on the reclaimed sedimentary pond near the Janikosoda Production Plant in Janikowo is still a source of pollution of groundwater. On one of the ponds near the Production Plant in Janikowo, three points were located, in which drilling was done up to the bottom of the layer of solid waste. In each point, samples of sediments were taken to determine electrolytic conductivity and chloride concentration. In order to examine the level of groundwater pollution in the area of the Production Plant, four points around the sedimentary ponds were identified, in which regular monitoring of chloride ions has been carried out since the 1980s. Based on analysis, it was concluded that chlorides are leached from the sediments deep into the soil profile by rainwater and, with high probability, also by water seeping from the adjacent slag pond. Sedimentary ponds are still an important source of pollution released into soils and groundwater around the plant. Nevertheless, chloride concentration in solid waste and groundwater in the area of sedimentary ponds has decreased in the last 20 years.

“…Innovative environmental monitoring systems and treatment strategies have been developed to address the unique challenges associated with mixed contaminant scenarios that occur at the SRS, often through active interdisciplinary collaboration with researchers from other USDOE facilities, academic and federal institutions, and commercial entities. Significant contributions have been made to several areas of environmental research and remediation, including monitored natural attenuation, enhanced bioremediation, phytoremediation, in situ contaminant immobilization, contaminant speciation, and the use of horizontal wells and direct‐push monitoring technologies, to name a few (e.g., Baladi et al, 2003; Bertsch et al, 1994; Brockman et al, 1995; Denham and Lombard, 1995; Flach et al, 2005; Hazen and Fliermans, 1992; Hinton et al, 2006; Lombard et al, 1992; Looney et al, 1995; Nichols et al, 2002; Phifer et al, 2005; Sink et al, 2005; USDOE, 1995a; Vangelas et al, 2006; Witt, 2006). Addressing the diverse environmental challenges of the site provides the unique opportunity to conduct both fundamental and applied research across a range of experimental scales.…”

The USDOE Savannah River Site (SRS), an 803-km 2 (310-mile 2 ) facility located south of Aiken, SC on the upper Atlantic Coastal Plain and bounded to the west by the Savannah River, was established in the 1950s for the production and refi nement of nuclear materials. To fulfi ll this mission during the past 50 years SRS has operated fi ve nuclear reactors, two large chemical separation areas, waste disposal facilities (landfi lls, waste ponds, waste tanks, and waste stabilization), and a large number of research and logistics support facilities. Contaminants of concern (COC) resulting from site operations include chlorinated solvents, radionuclides, metals, and metalloids, often found as complex mixtures that greatly complicate remediation efforts when compared with civilian industries. The objective of this article is to provide a description of the lithology and hydrostatigraphy of the SRS, as well as a brief history of site operations and research activities as a preface to the current special section of Vadose Zone Journal (VZJ) dedicated to SRS, focusing mainly on issues that are unique to the USDOE complex. Contributions to the special section refl ect a diverse range of topics, from hydrologic tracer experiments conducted both within the vadose and saturated zones to studies specifi cally aimed at identifying geochemical processes controlling the migration and partitioning of specifi c contaminants (e.g., TCE, 137 Cs, U, and Pu) in SRS subsurface environments. Addressing the diverse environmental challenges of the SRS provides a unique opportunity to conduct both fundamental and applied research across a range of experimental scales. Hence, the SRS has been a pioneering force in several areas of environmental research and remediation, often through active interdisciplinary collaboration with researchers from other USDOE facilities, academic and federal institutions, and commercial entities.
