From introduction: This is one of a series of County ground-water reports authorized by the Water Supply Act of 1958 and its companion Water Bond Act. These reports present assembled data and interpretation on the availability, occurrence, movement, and chemical quality of ground water in New Jersey.

From introduction: The purpose of this study is to simulate the hydrology of the Farrington aquifer using a computer-simulation model so that the effects of alternative withdrawal schemes can be evaluated quantitatively. The primary study area consists of the northern part of the New jersey Coastal Plain...This report discusses the geohydrology of the Farrington aquifer, the simulation model, and the effects of projected withdrawals from the Farrington aquifer.

From purpose and scope: The purpose of the present study by the U.S. Geological Survey in cooperation with the Division of Water Resources of the New Jersey of Environmental Protection is to make a quantitative hydrologic analysis of the known buried valley-fill aquifer in southwestern Essex and southeastern Morris County Counties in order to provide water-resources planners with the hydrologic bases to plan ground-water development and to allocate available water.

From introduction: The purpose of this investigation is to collect and interpret the basic hydrologic and geologic data and to appraise and report on the ground-water resources of Camden County. The objectives were to define the thickness and areal extent of the hydrologic units, evaluate the hydraulic characteristics of the aquifers, determine the effect of pumpage on the water levels of the area, define the source of recharge of the aquifers, and to evaluate the chemical quality of the ground water.

Report and geographical survey. This report includes geographic data of the Englishtown Formation of the Matawan Group of the Late Cretaceous age. It includes maps and tables.

From introduction: The purpose of the study was to assemble data on the occurrence, movement, availability and chemical quality of ground water in the Hackensack River basin in Bergen and Hudson Counties, New Jersey; to evaluate and interpret the data; and to make the results available to the public.

Abstract: Chemical and microbiological data from four characteristically acidic streams in southern New Jersey were used to evaluate seven factors related to the proclivity of each stream to nitrify under the influence of secondary sewage effluent. pH, water temperature, and dissolved oxygen were used as indicators of a stream conditions while neutralization of alkalinity, nitrogen species trends, BOD/NOD incubations, and nitrifying bacteria densities served as actual nitrification indicators. Hay Stack Brook showed strong evidence for nitrification on the basis of all four nitrification indicators while Landing Creek was nitrifying little if at all. Hammonton Creek is apparently nitrifying, but because of uncertainty in the downstream trends of the nitrogen species, and a lower level of alkalinity neutralization, it is nitrifying less than Hay Stack Brook. Squankum Branch showed some evidence for nitrification on the basis of the BOD/NOD incubations. The acidic character of these streams does not appear to be an exclusive factor in determining whether the stream will undergo nitrification.

Abstract: The findings of a problem-oriented, river-system investigation of the water quality and streamflow characteristics of the Raritan River, N.J. are described. Information on streamflow duration, time-of-travel measurements, and analyses of chemical, biochemical and physical-water quality are summarized and used to define relations existing between water quality, streamflow, geology, and environmental development in the basin's hydrologic system. Stream quality, particularly in the lower urban areas of the basin, is shown to be deteriorating with time at most of the sampling sites reported. For example, average dissolved-oxygen concentration is reported to be undersaturated at all sampling sites and is decreasing with time at most sites. Biochemical-oxygen demand is increasing at most sites, as are the dissolved-solids content.
