In the final formula- tion of the work program it was recommended that the raw ,wastewater, samples be screened by gas chroma- tograph/mass spectrometry for all volatile and ,acid,-neutral semivolatile organic ,pollutants, previously under study in the Agency's BATEA Review Program. The compounds under investi- gation are presented in Table 1.
