    In , one of the surface impoundments at the Tennessee Valley Authority’s (TVA) Kingston Fossil Fuel Plant failed causing CCR (also known as coal ash) and water to spill into the Emory and Clinch Rivers, flooding acres of land, and forcing a nearby neighborhood to evacuate. The potential for ground and surface water contamination from a surface impoundment depends on a number of factors, including: (1) siting considerations; (2) composition, mobility, and compatibility of the waste material; (3) geology, hydrology, and climate of the site and surrounding area; (4) construction of the surface impoundment;.

Sources and areas of observed contamination are central to the evaluation of the likelihood of release factor categories and the hazardous waste quantity factors.

    For instance, leaching of trace elements (Se, V, etc.) from coal ash ponds to adjacent surface water and shallow groundwater was found in the southeastern United States [38]. Herewith, the results.   mile of the impoundment, with the nearest home less than feet away. Nearby homeowners petitioned ATSDR to evaluate whether exposure to chemicals detected in the air, groundwater and surface water could affect their health. Residents are concerned about potential exposures to contaminants in both air and water.

PREFACE The Manual for Evaluating Contamination Potential of Surface Impoundments was prepared specifically for implementing a standardized evaluation system for the EPA Office of Drinking Water Surface Impoundment Assessment (SIA) and serves as the training manual.

The steps used in this system are outlined in Figure The SIA Manual for Evaluating Contamination of Potential of Surface Impoundments is reprinted in Appendix A. of data used in this study. sources listed as "Other": Figure illustrates the sources Here. Equation (6), in combination with the previous example problem result, gives: e = 9 ' I () = cm/mo In evaluating surface impoundments, the hydraulic gradient is augmented by the liquid ponded within the lagoon.

In this case, the flow quantity is given by: + H where H = depth of liquid in the lagoon. A procedure for evaluating soil data for closure of surface impoundments is presented and illustrated with data from an actual case study.

Steps in the methodology are: design of soil sampling program; evaluation of data, and determination of the extent of by: 2.

In evaluating the release potential from surface impoundments one key factor is the potential hazard of the chemicals generally found in impoundments.

More than half of the impoundments contained wastewater with six or more of the target chemicals while the sludges within the impoundments were reported to contained far fewer by: Principles, Practices, and Applications. Author: William J. Hinze,Ralph R. von Frese,R. Von Frese,Afif H.

(c) I concur that surface water monitoring will not be required since the potential to impact surface water no longer exists. (d) I concur that unsaturated zone monitoring will not be required since ground water contamination has already been detected and the surface impoundments no longer provide a source for subsurface contamination.

utilized to evaluate potential contamination by a method described by Silka and SwearingenJ^ By developing a rating for the (1) waste hazard potential, (2) ground water availability and quality, (3) soil zone, and (4) proximity of water supplies, a net potential for drinking water contamination from leaching can be determined.

Specific objectives of the "Surface Impoundment Assessment" (SIA) were to: 1) increase the States' awareness and data base concerning impoundments; 2) determine their numbers, location and potential effects on ground water; 3) solicit States' positions and suggestions on the Federal role in ground-water protection from this contamination source; and provide EPA with information to allow.

Introduction. This paper presents information collected as part of a multi-year research project sponsored by the US EPA Pitt et al.,Pitt et al.,Pitt et al.,Pitt et al.,Clark and Pitt, and addresses potential groundwater contamination problems associated with stormwater infiltration.

Several categories of constituents are discussed that are known to affect. Potential environmental impacts result from leakage of contaminated co-produced water beneath the impoundments into alluvial valley sediments, soils, bedrock, and near-surface aquifers.

INTRODUCTION.After evaluating impoundment settings and operations and confirming there was potential for releases, EPA went a step further and conducted a risk assessment to examine the degree to which the chemicals found in impoundments were likely to be released from impoundments and ultimately expose people to harmful chemicals.This section provides a discussion of the potential human health and environmental impacts and risks associated with these release mechanisms.
