EXECUTIVE SUMMARY

[Summarize the investigation steps and results, and cleanup actions completed, if any. Include description of the source(s), nature, extent and distribution of contamination, potential migration pathways, and the current and future risk that contamination poses to human health and the environment. Show that any proposed or completed cleanup actions are protective of human health and the environment; and treats hot spots of contamination to the extent feasible. Describe the residual risk following completion of the removal or remedial action.]
