#' Background Concentrations

#' @description Water-quality background concentrations for selected radionuclides, organic compounds,
#'   and chemical constituents that were analyzed for in water from the eastern Snake River Plain aquifer
#'   at and near the Idaho National Laboratory (INL).
#'   The background concentrations are defined as groundwater influenced by western tributary recharge
#'   in the western INL and by eastern regional recharge in the eastern INL.
#'   These concentrations are either naturally occurring or anthropogenic
#'   (substances present in the environment as a result of human activities)
#'   and are not influenced by waste and wastewater disposal at the INL,
#'   according to Bartholomay and Hall (2016).

#' @format A data frame with columns:
#'   \describe{
#'     \item{`parm_nm`}{Long parameter name,
#'       such as "Strontium-90, water, unfiltered, picocuries per liter".}
#'     \item{`pcode`}{U.S. Geological Survey 5-digit parameter code used to identify the constituent measured,
#'       see [`parameters`] dataset for details. For example, the parameter code for Tritium is "07000".}
#'     \item{`bkgrd_min`}{Minimum limit of background concentration.}
#'     \item{`bkgrd_max`}{Maximum limit of background concentration.}
#'     \item{`reference`}{Source of background concentration limits.
