DGS releases new DGIR web application

Delaware Geologic Information Resource (DGIR) Web Application

The Delaware Geological Survey has released the Delaware Geologic Information Resource (DGIR), an online data display tool and map viewer for geologic and hydrologic information, as a "beta" site. DGIR was designed to provide the Delaware professional community with a variety of geoscience data in one application. DGS will continue to refine the both the data and functionality of the website as it is reviewed.

The Delaware Geologic Information Resource (DGIR) is an online data display tool and map viewer for a variety of geologic and hydrologic information released by the Delaware Geological Survey. It was designed to deliver the most commonly available and requested geologic and hydrologic information that is appropriate for use in hydrologic studies, required by regulation and ordinance, and to support state resource management decisions.

NGWA Protect Your Groundwater Day

NGWA Protect Your Groundwater Day

September 11, 2012 is Protect Your Groundwater Day. This annual recognition is promoted by the National Ground Water Association (NGWA) to spotlight how individuals can protect and reduce health risks to an important drinking water source for rural America—groundwater.

Monitoring our water - Delaware Geological Survey improving groundwater monitoring efforts with new wells, sampling

Scott Andres examines sediment samples extracted from more than 500 feet underground for clues about the amount and quality of water available in central Delaware.

Delaware Geological Survey improving groundwater monitoring efforts with new wells, sampling. Scientists are digging for answers about the amount and quality of water available underground in central Delaware, where ongoing development will put increasing demands on water supplies in the coming decade.

The Delaware Geological Survey (DGS) is installing 7,700 feet of wells at eight sites in southern New Castle and northern Kent counties to improve groundwater-monitoring efforts, supported by a $600,000 grant from the Delaware Department of Natural Resources and Environmental Control (DNREC). Groundwater is the primary source of drinking water south of the Chesapeake and Delaware Canal, and populations there are projected to continue expanding.

Well and Water Level Summary for Wells with 4 or More Observations

Well and Water Level Summary for Wells with 4 or More Observations - Well Cb15-04

Groundwater levels are basic information needed for evaluating water conditions and for basic and applied research. For these efforts, water levels are being measured statewide in wells completed in multiple aquifers. Some wells are measured for specific projects, such as the Coastal Aquifers Salinity Project and the Water Conditions program, while other wells are measured so that staff can maintain long-term records of groundwater levels for evaluation of trends.

Table contains summary data from wells having 4 or more water level observations.

Ground-water levels are basic information needed for evaluating water conditions and for basic and applied research. For these efforts, water levels are being measured statewide in wells completed in multiple aquifers. Some wells are measured for specific projects, such as the Coastal Aquifers Salinity Project and the Water Conditions program, while other wells are measured so that staff can maintain long term records of ground-water levels for evaluation of trends.

Groundwater levels are basic information needed for evaluating water conditions and for basic and applied research. For these efforts, water levels from various aquifers are being measured statewide. Some wells are measured for specific reasons, such as for the Coastal Aquifers Salinity Project and the Water Conditions Report, while other wells are measured so that staff can maintain long-term records of groundwater levels for evaluation of trends.

Delaware Geological Survey welcomes new director Wunsch

David R. Wunsch is the new Director and State Geologist at the Delaware Geological Survey.

Study takes look at region's water - Growth areas' quantity, quality is focus

Scientists will sink more than 1.4 miles of wells into northern Kent County and southern New Castle County aquifers in the coming year, hoping to pump out a flood of new information about groundwater quantity and quality in current and future growth areas.

Delaware Groundwater Monitoring Network

The Delaware Geological Survey (DGS) currently monitors groundwater levels in a network of 68 wells in Delaware. Long time-series of water levels in major aquifers serve as critical baseline data for resource management and analyses of aquifer response to pumping, climatic variability, drought hazards, seawater intrusion, and interaction with streams and their ecosystems.

DGS Participates in the Delaware Estuary Conference

Partnership for the Delaware Estuary

DGS researchers Tom McKenna and John Callahan presented some of their work at the Delaware Estuary Science and Environmental Summit at Cape May, NJ, and hosted by the Partnership for the Delaware Estuary.

The Delaware Water Conditions Summary

The Water Conditions Summary is an online monthly summary of water conditions in Delaware. Principal factors in determining water conditions are precipitation, streamflow, and groundwater levels in aquifers. Data from rain gages, stream gages, and observation wells located throughout Delaware have been collected and compiled since the 1960s by the Delaware Geological Survey. These data are displayed as hydrographs and are also available for download. In general, water is abundant in Delaware, but supply is restricted by natural geologic conditions in some areas, by contamination in others, and is dependent on precipitation.

SP11 Instructions for Preparation of Delaware Geological Survey Data Base Schedules

SP11 Instructions for Preparation of Delaware Geological Survey Data Base SchedulesInstructions for Preparation of Delaware Geological Survey Data Base Schedules

The DGS, in response to the needs for efficient storage, manipulation,retrieval, and report-generating capability, has proceeded with the conversion of the paper file data base to an integrated automated geologic, hydrologic, and mineral resource management information system. It is necessary to organize data in a systematic and standardized fashion for efficient entry into the automated system. To accomplish this, the DGS has made major revisions in the data recording and filing systems.

This report contains the new DGS data schedules, describes the information that should be recorded on each schedule, and presents instructions for preparation of the schedules. The schedules are designed to make various kinds of data consistent with the input format screens utilized in the automated system.

The types of schedules described include:
1. Well
2. Water Level
3. Lithologic Log
4. Sample
5. Aquifer Test
6. Geophysical Log
7. Field Water Quality
8. Laboratory Water Quality
9. OCS Well

Web-Delivered Application for Hydrogeologic Data

Project Contact(s):

This project is designed to deliver, by web-based technologies, the most commonly available and requested geologic and hydrologic information used in hydrologic studies required by regulation and ordinance and used by state agencies to support resource-management decisions. Available information can be associated with points or areas. Information associated with points includes descriptive logs, geophysical logs, raw and interpreted groundwater levels, aquifer and geologic unit identification, and hydraulic characteristics of wells. Information associated with areas is either in the form of raster-based (grid) data or polygons. Examples of raster-based data include water-table depths and elevations, tops and thicknesses of geologic and aquifer units, and aquifer transmissivity. Examples of polygons include surficial geology and groundwater recharge potential.

The intent of developing a web-technology enabled system is to provide a more intuitive and comprehensive toolset for locating, quickly viewing, and downloading the desired information in an efficient, extensible, and familiar manner.
