Item Investigation of Elevated Sodium and Chloride in Well Water, Village of Columbia, Knowlton Township, Warren County, New Jersey(Trenton, N.J. : New Jersey Department of Environmental Protection, Water Resources Management, 2022) New Jersey. Department of Environmental Protection. Division of Water Supply and Geoscience. New Jersey Geological and Water Survey; Lubenow, Brady; Gagliano, Michael; Spencer, Michelle; Bousenberry, Raymond; Spayd, StevenAn investigation of elevated sodium and chloride concentrations in well water was conducted in the Village of Columbia, Knowlton Township, Warren County, New Jersey. Water testing was made available at no cost to residents and 82 private wells throughout the Township were sampled and tested for sodium and chloride in November 2015. Of these wells, 25 were also tested for additional water quality parameters to help categorize water in different aquifers and different parts of the Township. A follow-up well water sampling event for chloride and lead was conducted in May 2016 at no cost for residents. A continuous water quality monitor was placed within one of the wells with the highest concentrations to measure water quality over a 3.7-year timeframe. The karst geology was confirmed by review of available well records and borehole geophysics conducted in four wells. Surface geophysics, including resistivity and electrical conductivity, were conducted to help characterize water quality upgradient and downgradient of the accessible Township Storage Area. Elevated concentrations of sodium and chloride, often above New Jersey Secondary Maximum Contaminate Levels (SMCL), in private wells in the Village of Columbia, was confirmed.Item Reservoir Operations in New Jersey Preceding Hurricane Sandy, October, 2012(Trenton, N.J. : New Jersey Department of Environmental Protection, Water Resources Management, 2018) Hoffman, Jeffrey L.Item Highest Elevations by County in New Jersey(Trenton, N.J. : New Jersey Department of Environmental Protection, Water Resources Management, 2017) Petriman, AlexandraItem Protocol for Heavy Liquid Separation of Heavy Minerals and Recovery of Non-Toxic Separation Liquids(Trenton, N.J. : New Jersey Department of Environmental Protection, Water Resources Management, 2016) Uptegrove, Jane; Reier, Sandra A.; Muller, F.L.Item Nitrate Concentrations in Groundwater of New Jersey’s Highlands(Trenton, N.J. : New Jersey Department of Environmental Protection, Water Resources Management, 2014) Hoffman, Jeffrey L.; Petriman, AlexandraItem Changes in Groundwater Recharge Resulting from Development in Atlantic, Mercer and Sussex Counties New Jersey 1995-2007(Trenton, N.J. : New Jersey Department of Environmental Protection, Water Resources Management, 2013) Thompson, Charles; Hoffman, Jeffrey L.Item Using the Stream Low Flow Margin Method to Assess Water Availability in New Jersey’s Water Table Aquifer Systems(Trenton, N.J. : New Jersey Department of Environmental Protection, Water Resources Management, 2013) Domber, Steven; Snook, Ian; Hoffman, Jeffrey L.Item New Jersey Water Supply Planning Activities in 2012(Trenton, N.J. : New Jersey Department of Environmental Protection, Water Resources Management, 2013) Hoffman, Jeffrey L.Item Hydrogeologic Testing and Reporting Procedures in Support of New Jersey Water Allocation Permit Applications(Trenton, N.J. : New Jersey Department of Environmental Protection, Water Resources Management, 2012) Hoffman, Jeffrey L.; Petriman, Ovidiu; Bleicher, Mike; Boyle, Jim; Domber, Steve; French, Mark; Gheen, Jan; Johnson, Steve; Mennel, Bill; Myers, Jennifer; Nicholson, Laura; Rancan, Helen; Roman, Eric; Shim-Chim, RichardItem Results of an Aquifer Test in Chatham Borough Morris County New Jersey May 1992(Trenton, N.J. : New Jersey Department of Environmental Protection, Water Resources Management, 2012) Hoffman, Jeffrey L.Item Reconstructed Streamflow in the Musconetcong River at Lake Hopatcong(Trenton, N.J. : New Jersey Department of Environmental Protection, Water Resources Management, 2010) Hoffman, Jeffrey L.Item They Hydroecological Integrity Assessment Process in New Jersey(Trenton, N.J. : New Jersey Department of Environmental Protection, Land Use Management, 2009) Hoffman, Jeffrey L.; Rancan, Helen L.L.Item Revisions to New Jersey's HUC14s, 2009, with a Correlation to HUC12s(Trenton, N.J. : New Jersey Department of Environmental Protection, Division of Water Resources, 2009) Hoffman, Jeffrey L.; Pallis, TedItem Field Tests Using a Heat Pulse Flow Meter to Determine its Accuracy for Flow Measurements in Bedrock Wells(Trenton, N.J. : New Jersey Department of Environmental Protection, Division of Water Resources, 2006) Herman, Gregory C.Item Modifications to New Jersey's Watershed Management Area Boundaries, 1996-1999(Trenton, N.J. : New Jersey Department of Environmental Protection, Division of Water Resources, 2004) Hoffman, Jeffrey L.Item Development of New Jersey Drought Regions(Trenton, N.J. : New Jersey Department of Environmental Protection, Division of Water Resources, 2001) Hoffman, Jeffrey L.Item Basin Factor Calibration for Ground Water Recharge Estimation(Trenton, N.J. : New Jersey Department of Environmental Protection, Division of Water Resources, 1999) Hoffman, Jeffrey L.Item Comprehensive Chemistry of Select Greensand from the New Jersey Coastal Plain(Trenton, N.J. : New Jersey Department of Environmental Protection, Division of Water Resources, 1998) Dooley, John H.Item Determination of Bedrock Topography and Geology Using Various Geophysical Techniques(Trenton, N.J. : New Jersey Department of Environmental Protection, Division of Water Resources, 1989) Ghatge, Suhas L.; Pasicznyk, David L.; Sandberg, Stewart K.; Hall, David W.; Groenewold, John C.Item Annual Summary of Phytoplankton Blooms and Related Conditions in New Jersey Coastal Waters Summer of 1988(Trenton, N.J. : New Jersey Department of Environmental Protection, Division of Water Resources, 1989) Olsen, Paul; Kurtz, Barbara
