Abstract : A preliminary evaluation was made of the pre-extraction analytical holding time for white phosphorus in surface water samples. The purpose of the study was to determine the feasibility of shipping samples from a field site to a laboratory prior to extraction into an organic solvent. An initial screening study using spiked waters from four sources (reagent-grade water, well water, river water and salt marsh water) showed that white phosphorus was stable in the two surface waters for approximately one week provided precautions were taken to minimize losses to volatilization. Significant losses were observed in the reagent-grade water and the well water matrices. Following an ASTM standard, a holding time of six days was determined for surface water samples maintained at 4 deg C. Holding time, Water analysis, Surface water, White phosphorus
