DGS02-1 New Jersey Geological Survey Hydro Database
(700 KB) (Updated 1-30-2012)
The NJGS hydrologic properties database is a compilation of values for the hydrologic properties of geologic materials in New Jersey. The Microsoft (MS) Access97 database (hydro.mdb) includes values derived from the analysis of aquifer pumping tests, in-situ hydrologic testing such as slug injection and removal tests, lab permeameter tests, etc. The compilation is ongoing. Values are added on a regular basis as tests are analyzed and quality control is completed. The data are intended to be used for characterization of the hydrogeologic properties of individual geologic and hydrogeologic units throughout the state. Applications include prediction of hydrologic impacts of ground-water extraction, analysis of the sustainable yield of water supply wells, the rate of movement of ground-water contaminants through aquifers, etc. All data entered into the database have been examined or generated by an NJGS hydrogeologist. Quality control measures include a critical evaluation of the source of the data, the quality of the data, the testing methodology used, the appropriateness of the analytical method used relative to the hydrogeologic setting in which the testing occurred, among other considerations.
This publication originally included the look up table "hydroref" which has been removed from here and is now being published as the Hydrogeologic Nomenclature Reference Table (DGS05-3).
