Summary

This tabular data set represents select geochemical characteristics based on Olson geology types in surface or near surface geology (Olson, 2014) compiled for two spatial components of the NHDPlus version 2 data suite (NHDPlusv2) for the conterminous United States; 1) individual reach catchments and 2) reach catchments accumulated upstream through the river network. The select geochemical characteristics in surface or near surface geology are: 1) mean percentage of lithological calcium oxide (CaO), 2) mean lithological compressive strength, measured as uniaxial compressive strength (in megaPascals, MPa), 3) mean percentage of lithological phosphorus pentoxide (P2O5), 4) mean percentage of lithological potassium oxide (K2O), 5) mean [...]

Purpose

This data set was created by the U.S. Geological Survey's (USGS) National Water-Quality Assessment Project (NAWQA) which is part of the USGS National Water Quality Program (NWQP). This effort was undertaken to estimate select geochemical characteristics based on Olson geology types in surface or near surface geology for NHDPlusV2 flowline catchments and upstream river networks to support statistical analysis, map display, and model parameterization.
