Totals of 627 water and 1482 sediment samples were collected from 1529 locations at the nominal density of one location per 10 km/sup 2/. Water samples were collected from streams, springs, and wells, and sediment samples were collected from streams and springs. Elemental concentrations, field measurements, weather, geologic, and geographic data for each sample location are listed for waters and for sediments. Uranium/thorium ratios for sediment samples are also included. All elemental analyses were performed at the LASL. Water samples were initially analyzed for uranium by fluorometry. All water samples containing more than 40 ppB uranium were reanalyzed by delayed-neutron counting (DNC). All sediment samples were analyzed for uranium by DNC. Other element concentrations in sediments were determined by neutron activation analysis for 31 elements (aluminum, antimony, barium, calcium, cerium, cesium, chlorine, chromium, cobalt, dysprosium, europium, gold, hafnium, iron, lanthanum, lutetium, magnesium, manganese, potassium, rubidium, samarium, scandium, sodium, strontium, tantalum, terbium, thorium, titanium, vanadium, ytterbium, and zinc), by x-ray fluorescence for 9 elements (bismuth, cadmium, copper, lead, nickel, niobium, silver, tin, and tungsten), and by arc-source emission spectrography for lithium and beryllium. Analytical results for sediments are reported as parts per million.
