Double-disk solid-phase extraction--Simultaneous cleanup and trace enrichment of herbicides and metabolites from environmental samples Double-disk solid-phase extraction--Simultaneous cleanup and trace enrichment of herbicides and metabolites from environmental samples

Phenylurea and triazine herbicides, including some metabolites, were isolated from water and soil extracts by solid-phase extraction using a layered system of two extraction disks, a method called double-disk solid-phase extraction. The first disk consisted of strong anion exchange (SAX) of 10-μm styrene divinylbenzene (SDB) particles embedded in Teflon, and the second disk was a C18...

Hydrogeologic structure of the Newark Basin, Pennsylvania, from borehole geophysical logs Hydrogeologic structure of the Newark Basin, Pennsylvania, from borehole geophysical logs

The Brunswick and the underlying Lockatong Formations are comprised of littrifled Mesozoic sediments that constitute part of the Newark Basin in southeastern Pennsylvania (USA). These fractured rocks form an important regional aquifer that consists of gmdational sequences of shale, siltstone, and sandstone, with fluid transport occurring primarily in fractures. An extensive suite of...
