Design of a GIS-based rating protocol to assess the potential for landfill closure using dredge material in post Hurricane Sandy New Jersey.

New Jersey is rapidly running out of capacity for storage of dredged material. A potential solution to this lack of storage space is to remove and reuse the dredged material for some beneficial use. Results from a Rutgers University project performed for the New Jersey Department of Transportation, Office of Maritime Resources, designed to assess the potential for closure of New Jersey landfills using dredge material from existing Confined Disposal Facilities (CDFs) are presented and discussed.

Comparison of kriging and cokriging for the geostatistical estimation of specific capacity in the Newark Basin (NJ) aquifer system.

Groundwater is a major water source in New Jersey; hence, accurate hydrogeologic data are extremely important. However, most measured data have inadequate spatial density and their locations are often clustered. Our study focuses on implementing geostatistical methods to generate the spatial distribution of specific capacity over the Newark Basin in New Jersey.

Comparison of a novel profile method to standard chamber methods for measurement of sediment oxygen demand.

A methodology is presented to determine the impact of flow rate upon sediment oxygen demand (SOD) based upon dissolved oxygen transport through the logarithmic boundary layer in stream systems. Previous work has used profile methodology to estimate atmospheric fluxes of pollutants from sediment, and similar principles are applied in this study. Chamber and profile SOD measurements were collected on July 21, 2009 in the Millstone River in Hillsborough, NJ and on July 22 and 28, 2009 in the Lawrence Brook in Milltown, NJ.

Modeling the Hydrology and water quality using BASINS/HSPF for the upper Maurice River watershed, New Jersey.

Results of developing a watershed model for the Upper Maurice River watershed are presented. The model was calibrated against observed stream-flow using local coastal plain meteorology as input, for the ultimate purpose of estimating future development impacts on local hydrology, stream-flow and water quality. Due to insufficient data, the model has not been validated yet.

Temperature effects on tubificid worms and their relation to sediment oxygen demand.

Sediment samples were collected from the Dead River in New Jersey and tested in the laboratory under two temperature conditions, 4 degrees C and 20 degrees C. The study was conducted to determine the effect of worm density on the sediment oxygen demand (SOD) rate and if temperature affects the ability for tubificid worms to deplete dissolved oxygen (DO) from the overlying stream water. The study showed that the DO concentration was affected by tubificid worm density and that higher temperature increased the metabolic activity of the worms.
