Parameter Information

Description

Parameter information for selected chemical constituents, organic compounds, and radionuclides measured for in water samples collected from monitoring sites in the U.S. Geological Survey (USGS) water-quality monitoring network, Idaho National Laboratory and vicinity, Idaho.

Usage

parameters

Format

A data frame with columns:

pcode

USGS 5-digit parameter code.

parm_group_nm

Parameter group name. Abbreviations and descriptions are as follows: "Information" includes information about the water sample such as the date and time of collection, the location of the sample, and the method of analysis used; "Inorganics, Major, Metals" includes major inorganic ions and metals, "Inorganics, Major, Non-metals" includes major inorganic non-metallic ions; "Inorganics, Minor, Metals" includes minor inorganic metallic ions; "Inorganics, Minor, Non-metals" includes minor inorganic non-metallic ions; "Nutrient" includes nutrients such as nitrogen and phosphorus that can be present in water samples; "Organics, Other" includes organic compounds that are not classified as pesticides or PCBs; "Organics, Pesticide" includes organic compounds that are used as pesticides, such as insecticides, herbicides, and fungicides; "Physical" includes physical characteristics of water; "Radiochemical" includes radioactive isotopes that can be present in water samples; and "Stable Isotopes" includes non-radioactive isotopes of elements that can be used to trace the movement of water through the hydrologic cycle.

parm_nm

Long parameter name, such as "Strontium-90, water, unfiltered, picocuries per liter".

casrn

Chemical Abstracts Service (CAS) registry number, such as "10098-97-2" for Strontium-90.

srsname

Substance Registry Services (SRS) name, such as "Strontium-90".

unit_cd

Units of measurement, see units dataset for unit descriptions.

min_dt

Collection date of first sample analyzed for the parameter.

max_dt

Collection date of last sample analyzed for the parameter.

nrecords

Number of records associated with the parameter.

nsites

Number of sampling sites where the parameter was observed.

Source

USGS water data acquired from the National Water Information System (U.S. Geological Survey, 2023). The SRS name (srsname) for "Trihalomethanes (four), total, from SDWA NPDWR" was shorten to its preferred acronym "TTHM4".
