USGS Groundwater Data for New Jersey

Click to hide state-specific text

ALL DATA ARE AT LOCAL TIME



Current Conditions
(40 sites)

Current conditions at selected sites based on the most recent data from on-site automated recording equipment. Measurements are commonly recorded at a fixed interval of 15- to 60-minutes and transmitted to the USGS every hour. Values may include "Approved" (quality-assured data that may be published) and/or more recent "Provisional" data (of unverified accuracy and subject to revision). Most current data are provisional.

Historical Observations
(166 sites)

The same data accessed by the Current Conditions link above but including both active and discontinued sites with data for any part of the period October 1, 2007, through the present. Values may include "Approved" (quality-assured data that may be published) and/or more recent "Provisional" data (of unverified accuracy and subject to revision).

Daily Data
(359 sites)

Summary of all data for each day for the period of record and may represent the daily mean, median, maximum, minimum, and/or other derived value. Values may include "Approved" (quality-assured data that may be published) and/or more recent "Provisional" data (of unverified accuracy and subject to revision).

Statistics
(358 sites)

Statistics are computed from approved daily mean data at each site. These links provide summaries of approved historical daily values for daily, monthly, and annual (water year or calendar year) time periods.

Field Measurements
(7,030 sites)
Manual measurements of depth to water in wells.
Introduction

The Ground-Water database contains ground-water site inventory, ground-water level data, and water-quality data. Additional ground-water information for New Jersey is available at the New Jersey Water Science Center web page. This page includes geologic maps, a description of the aquifers in New Jersey, and references to selected ground-water reports.

The ground-water site inventory consists of more than 5,500 records of wells and test holes in New Jersey. Available site descriptive information includes well location information (latitude and longitude, well depth, site use, water use, and aquifer.)

The USGS annually monitors ground-water levels in thousands of wells in the United States. In New Jersey long-term water-level data is available from more than 300 wells that are or have been part of our state-wide water-level observation network. Information on the water-level monitoring network including a map of site and a list of wells is available on the NJ Water Science Center home page. Water-levels are also available from project work and from a regional study that measures water-levels at more than 800 wells in confined Coastal Plain aquifers every 5 years.
