Abstract
The purpose of this report is to make available the records
of ground-water levels in the principal aquifers of the State through
1969 and to compile other related data, such as records of groundwater
pumpage, data on municipal, public and industrial water-supply
facilities, and the effects of precipitation on ground-water levels.
Records of water levels in areas of heavy pumpage, and in areas
where changes are principally from natural influences, are illustrated
or tabulated to allow comparison between these types of water-level
fluctuations. The water levels and related data provide a day-to-day
record for the evaluation of available ground-water supplies. The
long-term records serve as a framework to which short-term records
may be related.
This report is written for those persons, municipalities,
industries, institutions, consultants, drillers, and hydrologists
interested in the ground-water resources of the State.
Description
Table 1 contains records of measurements of ground-water levels
in observation wells, well locations, depths, elevations, aquifers
which they tap, and the extremes of water level for the past record
and in 1969. Table 2 contains records of ground-water pumpage in
1969 of most major ground-water users in the State.
Numerous hydrographs are included in the report to illustrate
changes of water level. Most of these illustrations also show the
effects on water levels of ground-water pumpage and variations in
precipitation.
Shown in summary form in the text, are supplementary data on
the yield of wells, pumpage, storage facilities, treatment, quality
of water, per capita use and trends of ground-water levels for
1969 and for part of the previous record.
