USING ISOTOPES EFFECTIVELY TO SUPPORT COMPREHENSIVE GROUNDWATER MANAGEMENT A. Introduction
ثبت نشده
چکیده
Many countries are not able to manage their water resources to sustainably meet current and future demands because they lack a comprehensive assessment of the quality and availability of their resources. The need for comprehensive assessments is well recognized, but often the required information is unavailable owing to gaps in hydrological information and understanding. These gaps are particularly acute with respect to groundwater resources.

Isotopic Composition of Nitrate as a Determination of Sources of Pollution
A range of isotopic methods (using radioactive and stable isotopes) have been used to investigate groundwater processes and to determine the sources and pathways for groundwater contamination. Methods using stable isotopes of nitrogen have been applied in a variety of Australian and international groundwater studies. Isotopic methods have involved either application of tracer isotopes or studyi...
متن کاملInvestigating Contaminant Inputs via Submarine Groundwater Discharge to Coastal Waters Using Radium Isotopes
Our long-term goal is to determine if submarine groundwater discharge (SGWD) is an important mechanism for delivering contaminants (i.e. heavy metals, organics) to harbors. We plan to accomplish this goal using a suite of naturally-occurring radium isotopes as tracers of SGWD and the dispersion of contaminants from the embayment (Buesseler/WHOI). In addition, we plan to develop a comprehensive ...
متن کاملA review of research dealing with isotope hydrology in Iran and the first Iranian meteoric water line
For more than half a century isotopes have been employed as a powerful tool in studying various aspects of water resources in a largenumber of countries. However, in developing countries like Iran the application of such techniques is in its infancy. The first research inIran was carried out in 1975 to identify the source of saline groundwaters in south Iran, and the first national conference o...
متن کاملIdentifying Seasonal Groundwater Recharge Using Environmental Stable Isotopes
In this study, the stable isotope values of oxygen and hydrogen were used to identify the seasonal contribution ratios of precipitation to groundwater recharge in the Hualien River basin of eastern Taiwan. The differences and correlations of isotopes in various water bodies were examined to evaluate the groundwater recharge sources for the Hualian River basin and the interrelations between grou...
متن کاملDemonstrating a natural origin of chloroform in groundwater using stable carbon isotopes.
Chloroform has been for a long time considered only as an anthropogenic contaminant. The presence of chloroform in forest soil and groundwater has been widely demonstrated. The frequent detection of chloroform in groundwater in absence of other contaminants suggests that chloroform is likely produced naturally. Compound-specific isotope analysis of chloroform was performed on soil-gas and groun...
