Abstract

The USGS, USEPA, and City of Lincoln Water System (Nebraska) have conducted a study to determine the occurrence and removal of EDTA, NTA, and nonylphenol monoethoxycarboxylate to nonylphenol pentaethoxycarboxylate (NP1EC-NP5EC) in the hydrologic system at the City of Lincoln well field. The objective of the study is to evaluate the occurrence and removal of EDTA, NTA, and total nonylphenolpolyethoxycarboxylate (NPEC) by bank filtration at the City of Lincoln well field. This presentation will discuss removal during two sampling periods — May and August 2002 — based upon surface-water fractions in the collector well calculated using stable isotope ratios of hydrogen and oxygen.
