rainfall runoff from the road surface. Partway along this stretch of roadway (near the turnoff to LBNL building 31) is a low spot at which particulates, mainly abraded from the road surface, collect against the curb. Normal LBF procedure is to collect at least two samples per year from these deposits - - one just before the onset of the rainy season (September or October), and one at the end of the rainy season (May or June). One to two kilograms of material is collected from the upstream end of one of these narrow deposits. After air-drying, the material is sieved, and that fraction which passes through a 1/16Ó mesh screen becomes the sample to be analyzed. Typically, the sieved material represents at least 80% of the total collected material. For analysis, these sediments are packed into one of the same counting containers as are used for soil samples. These procedures were followed for the samples listed in [**Table \[tab:sediment\]**]{}.
