This book was released on 2019 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Of the many streams and rivers in Texas, only a few have been previously included in the National Rivers and Streams Assessment (NRSA), a national water quality survey that recurs every five years. This research involved sampling a subset of 19 potential reference sites in Texas identified by NRSA but not previously sampled. All sites were located in the Colorado, Brazos, and Trinity River Basins. This study sought to bridge data gaps in the NRSA to include rural ecoregions, determine the extent to which rivers and streams support healthy biological conditions, and identify major stressors to inform management decisions. The study collected water chemistry data using field and laboratory methods in compliance with NRSA protocols. Each site was sampled in spring and summer to compare seasonal differences in water quality. Statistical analyses employed spatial comparisons of water quality among different streams by season, river basin, and watershed land use. Streamflow decreased at most sites from spring to summer. Total Kjeldahl nitrogen (TKN) showed large variability with a general increase from spring to summer across all river basins. Total phosphorus (TP) also increased from spring to summer in the Colorado and Trinity River Basins but decreased in the Brazos River Basin. The various trends displayed in these four water quality parameters suggests that land use is a significant driver of seasonal water and nutrient inputs to small streams. Overall, the large variability in the dataset supports the argument that multiple samples should be collected in a water quality analysis to capture seasonal changes as well as differences among ecoregions within the same river basin.

Available in PDF, EPUB and Kindle. Book excerpt: This document is intended to provide an overview of the major components of surface and ground water quality and how these relate to ecosystem and human health. Local, regional and global assessments of water quality monitoring data are used to illustrate key features of aquatic environments, and to demonstrate how human activities on the landscape can influence water quality in both positive and negative ways. Clear and concise background knowledge on water quality can serve to support other water assessments.
