Abstract

The Trinity River Basin National Water Quality Assessment (NAWQA) study-unit staff began assessment activities in 1991, and in 1992, undertook a retrospective review of existing data on pesticides. The main purpose of this review was to aid in the design of a pesticide-sampling network for the study unit. The review consisted of the compilation, screening, and analysis of available pesticide-sample information. In addition, important environmental factors, which influence the occurrence and distribution of pesticides in the study unit, were identified and compiled. A report of this review and analysis will be released in 1995 (Ulery and Brown, in press). This fact sheet provides a brief overview of significant findings.

Introduction The Earth changes continuously in response to natural processes and human activity. The collection and interpretation of time-series imagery enhances our ability to observe and monitor Earth’s dynamic processes as well as study and understand the rapidly changing surface of our planet. The Global Fiducials Library (GFL) provides repeated satellite imagery of selected locations around the world to help scientists observe, document, and better understand those changes over time.
