Summary

Delineate glacial deposits that may be a significant ground water resource for water resources evaluation and ground water protection.

Description

AQUIFER_POLYGONS contains polygons of significant aquifers (glacial deposits that are a significant ground water resource) for Maine mapped at a scale 1:24,000, from the Department of Conservation, Maine Geological Survey. Printed maps published by the Maine Geological Survey on USGS 7.5' quadrangle bases. Aquifer boundaries delineated and digitized by the Maine Geological Survey from data compiled on USGS 7.5' quadrangle bases. Aquifer polygons coded by yield expected from a properly constructed well (ATYPE = 0 area not mapped as aquifer; ATYPE = 1 10-50 gallons-per-minute; ATYPE = 2 greater than 50 gallons-per-minute; ATYPE = 3 island of non-aquifer material within an area mapped as aquifer). See aquifer_contacts data set for aquifer contact characteristics.

Data Quality 

Scope of quality information
Resource level  dataset




Data quality report - Conceptual consistency
Measure description 1: Aquifers are not mapped beneath water bodies 2: Aquifers are classified based on the expected yield to a properly constructed well. ATYPE = 0 is an area not mapped as aquifer. ATYPE = 1 is an area of aquifer expected to yield 10-50 gallons-per-minute to a properly constructed well. ATYPE = 2 is an area of aquifer expected to yield greater than 50 gallons-per-minute to a properly constructed well. ATYPE = 3 is an island of non-aquifer material within an area mapped as aquifer.




Data quality report - Completeness omission
Measure description Significant aquifers are defined as bodies of coarse grained glacial material with the potential to yield 10 or more gallons-per-minute (gpm) to a properly constructed well. Aquifers are defined with a potential to yield greater than 10 gpm and aquifers with the potential to yield greater than 50 gpm (high-yield aquifers).




Data quality report - Quantitative attribute accuracy
Measure description Attribution of the data set was checked for data entry errors through a series of reviews that checked for inconsistencies with interpretation results. The coverage has been checked for label errors and attribution is complete.




Data quality report - Absolute external positional accuracy
Dimension horizontal


Measure description The data were compiled on a 1:24,000 scale base with a horizontal accuracy +/- 40 feet or 12 meters. Aquifer boundaries are drawn based on field observations of surficial materials in gravel pits, stream banks, road cuts, and other exposures. Mapping is supplemented with seismic-refraction studies and the installation of observation wells and test borings, information from water-company exploration, large construction projects, town well inventories, and other sources. This information, along with aerial photography and previously published maps, allows the geologist to define the boundaries of favorable surficial deposits and estimate how well the deposits will yield water to a well. Although interpretation rests on an extensive base of geologic information, analysis of bedrock surface and surficial materials, more often than not, prohibits a precise quantitative measure of horizontal accuracy. In the aquifer_contact data set, an arc coded with LSYMBOL = 11 (solid line) represents a more clearly defined boundary location than those coded LSYMBOL = 12 (dashed line).

Description Significant aquifers are defined as bodies of coarse grained glacial material with the potential to yield 10 or more gallons-per-minute (gpm) to a properly constructed well. Aquifer boundaries are drawn based on field observations of surficial materials in gravel pits, stream banks, road cuts, and other exposures. This surficial geology mapping is supplemented with seismic-refraction studies and the installation of observation wells and test borings and information from water-company exploration, large construction projects, town well inventories, and other sources. This information, along with aerial photography and previously published maps, allows the geologist to define the boundaries of favorable surficial deposits and estimate how well the deposits will yield water to a well. The boundaries of favorable surficial deposits do not necessarily coincide with the aquifer boundaries. In some areas, a thin cover of favorable coarse-grained material may overlie fine-grained sediments, till, or bedrock. A well in that material would not be able to sustain a yield of 10 gpm, so the area would not be mapped as an aquifer. In other areas, fine-grained sediments or till may overlie favorable coarse-grained sediments and the subsurface deposit may not be recognized as an aquifer. Single- and 12-channel seismic-refraction studies are conducted to determine the saturated thickness of a deposit by establishing the depth to water table and bedrock surface. Installing monitoring wells and drilling test borings provide direct information about the aquifer characteristics of a deposit. This work provides information on the depth to water table and bedrock surface, water quality, and how easily the sediment transmits water. The information is compiled on a USGS 1:24000 topographic map. The aquifer contacts are based on an interpretation of information described above by a geologist and the aquifer contacts drawn on a stable mylar base. Aquifers with the potential to yield 10-50 gpm and aquifers with the potential to yield greater than 50 gpm (high-yield aquifers) are defined. The contacts were digitized to produce this data set.
