New, improved groundwater cleanup technology

Article Abstract:

AWD Technologies was able to help Lockheed Aeronautical Systems to comply with an order to eliminate contaminating chemicals from the groundwater at its Burbank, CA, facility. AWD's technology transfer agreement with Dow Chemical allowed it to develop the AquaDetox/vapor extraction system (VES) for treating soil and groundwater. The AquaDetox/VES facility has been in operation since 1988, and public reaction has been positive.

Potential for groundwater contamination in Mexico City

Article Abstract:

The high population density, intense industrial activity and its location in a closed hydrologic basin has given rise to concerns that Mexico City's crucial groundwater supplies may soon become contaminated by pollution. Some even contend that groundwater supplies have already been contaminated. Mexican authorities need to take a closer look at the environment and take the appropriate steps before the problem gets worse.

Identification of groundwater solute sources using boron isotopic composition

Article Abstract:

Background groundwater and water from anthropogenic sources at a site near El Paso, TX, showed different boron concentration and Boron stable isotopic values after injection with treated wastewater. This indicates that Boron stable isotopes are effective chemical and isotopic tracers for identifying various water types and sources.
