Title:Sodium, chloride and specific conductance in stream water and groundwater in New Hampshire 1991, 2000 – 2021
Alternate Identifier:DOI PLACE HOLDER
Abstract:

Stream water was collected at weekly to monthly intervals at 29 stream sites in New Hampshire (USA). Ten of the stream sites were instrumented with high‐frequency sensors. Twenty-one of the stream sites (including 5 sensor sites) are in the Lamprey River Hydrologic Observatory (LRHO; Wymore et al 2021) and two stream sites were nearby the LRHO. Groundwater was collected from two riparian well fields (JF, 14 wells and WHB, 13 wells). Wells were installed in 2004 and sampled monthly through May 2007, then quarterly until December 2009, after which a subset (JF, 6 and WHB, 5) was generally sampled quarterly. Stream and groundwater samples span a 17-year collection period and were analyzed for sodium, chloride and specific conductance. Methods and findings are described in the associated Limnology and Oceanography Letters manuscript.

Methods and Protocols

These methods, instrumentation and/or protocols apply to all data in this dataset:

Methods and protocols used in the collection of this data package
Description:

Stream water and groundwater samples:

Groundwater wells were installed in 2004 and are 5 cm diameter polyvinyl chloride wells with 53 – 76 cm of perforated well casing. Wells were hand augured to the depth of refusal (approximately 1 to 2.4 m below the ground surface). Wells were sampled monthly through May 2007, then quarterly until December 2009, after which a subset were generally sampled quarterly.

Stream water and groundwater samples are filtered (pre-combusted 0.7 μm Whatman GF/F glass fiber filter) and frozen prior to analysis. All analyses were conducted at the Water Quality Analysis Laboratory at the University of New Hampshire.

Laboratory, field, or other analytical methods:

Field measurements of specific conductivity were determined using either a YSI 556 or YSI ProDSS. Sodium (Na+) and chloride (Cl-) are analyzed using ion chromatography with suppressed conductivity detection (Dionex 1000 ICS with autosampler; Sunnyvale, CA; EPA 300.1). Detection limits for most of the collection period are 0.025 mg Cl/L and 0.02 mg Na/L.

Description:

Quality control:

Quality Control Samples (QCS; from Ultra Scientific or SPEC Certiprep) are analyzed periodically (approximately every 10-15 samples) in each sample analysis batch to assure accuracy. The response/unit concentration is also used to monitor day-to-day variation in instrument performance. A difference from the certified concentration of more than 10% requires further investigation of that run. A difference greater than 15% is failure (unless the average of the two samples is less than 10X the MDL), and results in re-analysis of the entire sample queue, unless there is a very reasonable and supported explanation for the inconsistency. At least 2 QCS are analyzed on each run.

Standards and reagents are prepared from reagent grade chemicals (typically JT Baker) or from pre-made stock solutions. All glassware is acid washed (10% HCl) and rinsed 6 times with ultra pure-low DOC water (18.2 mega-ohm). All analyses use multi-point calibration curves (4-7) points, which are analyzed at the beginning and the end of each run. A Laboratory Reagent Blank (LRB), Laboratory Fortified Blank (LFB; a standard run as a sample) and Laboratory Duplicate are analyzed every 10 to 15 samples during each run. At least one Laboratory Fortified Sample Matrix (LFM) is analyzed during each run to ensure that sample matrices do not affect method analysis efficiency.

Laboratory Duplicates must fall within 10% relative percent difference (RPD = abs(dup1-dup2)/average of dup1 and dup 2). A difference greater than 5% requires further investigation of the sample run. A difference greater than 10% is failure (unless the average of the two samples is less than 10X the MDL), and results in re-analysis of the entire sample queue, unless there is a very reasonable and supported explanation for the inconsistency. LFM must show 85% to 115% recovery. A recovery <90% or > 110% requires further investigation of the sample run. A recovery <85% or >115% is failure (unless the sample is less than 10X the MDL), and results in re-analysis of the entire sample queue, unless there is a very reasonable and supported explanation for the inconsistency. All QC information from each run is stored in a separate Access database. This includes calibration r2, error, slope and intercept. The prepared concentration and measured concentration of LFM and calibration standards analyzed throughout the run are also entered. Finally, the lab duplicate measured concentrations are included. All this information can be queried for the project manager. Control charts (PDF) are generated from this database in R and reviewed weekly by the lab manager.
