When present at > 1 [mu]g/mL, each title compound was determined in groundwater by ion-exclusion chromatography after sample acidification and filtration. For groundwater with one or all analyte concentrations of < 1 [mu]g/mL, the acid anions were first concentrated from a 100-mL sample using a quaternary amine anion-exchange cartridge. The acids were recovered by eluting the cartridge with 1 mL of N H[sub 2]SO[sub 4] and 2-mL deionized water washes; this solution then was examined by anion-exclusion chromatography. Analytes were monitored with a UV detector operated at 200 nm. The analysis procedures for groundwater were validated with solutions which were fortified with from 50 ng/mL to 200 [mu]g/mL of each analyte; recoveries ranged from 90 to 110%. The soil method was validated using fortified samples which contained each acid at concentrations of from 5 to 160 [mu]g/g. Recovery values were between 81 and 120%. For samples exhibiting minimal detector response from compounds other than the acids of interest, 100-[mu]L injection volumes provided an estimated detection limit of 1 [mu]g/g for soil and 10 ng/mL for groundwater.
