Guidelines for Preparing Hydrogeologic Reports for Water-Allocation Permit Applications, with an Appendix on Aquifer-Test Analysis Procedures

The New Jersey Department of Environmental Protection (NJDEP), through the Bureau of Water Allocation (BWA), reviews hydrogeologic reports submitted in support of applications for major water-supply allocations (more than 100,000 gallons per day). One frequent problem is inappropriate investigational and data-analysis techniques. This report presents guidelines for preparing a hydrogeologic report acceptable to BWA. It is a guide for designing a hydrogeologic investigation and then preparing and submitting the resulting report to NJDEP. This report does not cover all details of aquifer- testing procedures and ground-water hydraulics. Many ground-water texts do this; some are listed in the references. This report presents guidelines considered minimally acceptable by BWA and briefly describes appropriate methods of data analysis. Responsibility for the accuracy of the data and appropriateness of the analysis techniques lies with the applicant. High-capacity wells can supply a large population. The wells may have regional effects on ground-water levels and flow patterns. Additionally, drilling, testing, and installing pumps and water lines can be expensive. Ensuring that such a well is properly located so as to provide the required volume of water without affecting other ground-water users justifies requiring an accurate and thorough hydrogeologic evaluation. This report presents guidance in several different areas. These include the types of aquifer tests avail able, the appropriateness of each, some details on field procedures, appropriate analysis techniques and reporting requirements. This report was written at the request of, and with guidance from, the Bureau of Water Allocation. The guidelines reflect BWA's current (1992) practices. These are subject to change. An applicant should contact the BWA to learn of any changes. Temporary dewatering operations require a special permit. The process for applying for a dewatering permit is different from the process outlined in this report. The BWA will provide guidance when applying for a dewatering permit.Hoffman, Jeffrey L., Canace, Robert, Boyle, James, Blyskun, George New Jersey Geological Survey Geological Survey Report GSR 29This document is for sale from: NJDEP Maps and Publications Office Information - U.S. Postal Service purchases: DEP Map and Publication Sales Office P.O.
