OVERVIEW

Description/Abstract

Groundwater chemistry from two unscreened wells (GW1 and GW2) at Susquehanna Shale Hills Critical Zone Observatory from 2008-2010. Well are approximately 2.74 m deep and were sampled daily using automatic samplers (2700 series, Teledyne Isco, Lincoln, NE).

Comments

Four groundwater samples were collected at each well per sampling event. Three samples were filtered (0.45 μm Nylon syringe filters) and analyzed for major anions, cations and DOC, while the last samples was unfiltered and analyzed for oxygen and hydrogen stable isotopes. Cations and DOC samples were acidified in the laboratory with nitric and hydrochloric acids, respectively. DOC and stable isotopes samples were collected were collected in glass bottle and while major ion samples were collected in screw top Nalgene bottles.

Major cations and silica were analyzed on an inductively coupled plasma–optical emission spectrometer (ICP– OES), while major anions were measured on the Dionex Ion Chromatograph (Sunnyvale, CA). Dissolved organic carbon was analyzed using a Shimadzu TOC-5000A analyzer (Shimadzu Scientific Instruments, Columbia, MD). Oxygen and hydrogen stable isotopes were analyzed ion the DLT-100 liquid water stable analyzer (Los Gatos Research, Mountain View, CA).
