Science Datasets

The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Corrosivity index and streamflow datasets used to evaluate trends in potentially corrosive source waters in the Nation's streams and rivers (output) (1992-2012)

Changes in water corrosivity from 84 river sites were investigated using long-term (1962 – 2016) data sets. Corrosive waters, often having elevated chloride (Cl) concentrations, can lead to metal leaching and promote corrosion in water distribution systems. Two different indices, the Chloride-Sulfate Mass Ratio (CSMR) and the Larson Ratio (LR), are commonly used to
