Description:
A solid fertilizer sample is dissolved or leached to solutilize the perchlorate as the aqueous anion. If needed, the liquid is filtered or centrifuged. The rsulting solution is subjected to ion chromatography using an adaptation of EPA Method 314.0. Preliminary screenng is required to ensure the sample is amenable to ion chromatography and within the calibration range. Quality control and reporting requirements have been modified for the fertilizer matrices. Apparati and method must be documented as part of the supporting information. This method has been jointly approved for use in research projects by the Water Supply and Water Resources Division of EPA's National Risk Management Research Laboratory and by the Ecosystems Research Division of EPA's National Exposure Research Laboratory. However, this is NOT an EPA-approved method, and it has not been subjected to the Agency's protocols for issuing numbered methods.
