## Section 1: Overview

Originator:Minnesota Department of Natural Resources
Title: NRSFSNPY
Abstract: Near-surface pollution sensitivity in Blue Earth County, Minnesota. The sensitivity to pollution assessment of the near-surface materials estimates the time of travel for water to travel from the land surface to a depth of ten feet.
Purpose: Blue Earth County Geologic Atlas, Part B, County Geologic Atlas Series C-26
Time Period of Content Date:
Currentness Reference: data were acquired or accessed between 2011 and 2015
Progress: Complete
Maintenance and Update Frequency: None Planned
Spatial Extent of Data: Blue Earth County, Minnesota
Bounding Coordinates: -94.4
-93.8
44.3
43.8
Place Keywords: Blue Earth County, Minnesota
Theme Keywords: pollution sensitivity, near surface
Theme Keyword Thesaurus: None
Access Constraints: None
Use Constraints: Users may wish to verify critical information; sources include both the references here and information on file in the offices of the Minnesota Geological Survey and the Minnesota Department of Natural Resources. Every effort has been made to ensure the interpretation shown conforms to sound geologic and cartographic principles. This map should not be used to establish legal title, boundaries, or locations of improvements.

## Section 2: Data Quality

Attribute Accuracy: 1:100,000
Logical Consistency: Data are topologically correct using ArcGIS 10.2.2
Completeness: Complete
Horizontal Positional Accuracy: NA
Vertical Positional Accuracy: NA
Lineage: The sensitivity to pollution for near-surface materials is an estimate of the time it takes for water to infiltrate the land surface to a depth of 10 feet. It is intended to estimate the travel through the unsaturated zone to reach the water table, which is assumed to be 10 feet below land surface everywhere for the purposes of this method.
Matrix texture is defined as relative amounts of sand, silt, and clay. It is used as a proxy for estimating the transmission rate, as coarse-grained materials have transmission rates greater than fine-grained materials because of the larger and more connected pore spaces between the grains. The transmission rate is estimated with a two-layer approach using two primary inputs of matrix texture values: the soil layer (0 to 3 feet) and the underlying geologic materials (3 to 10 feet). Special conditions override this approach for regions where the geology dominates: karst within 50 feet of the land surface, bedrock conditions at or near surface.
In 2015 the Minnesota Geological Survey (MGS) created a statewide textural database of shallow geologic materials and the DNR defined specific transmission rates for two additional surficial geologic units: thick glacial lake clays and loess.
