Lake Waban Ecological
Risk Assessment, Wellesley, Massachusetts. Confidential Client.
Sample Preparation Supervisor.
Woods Hole Group provided
quarterly sampling and analysis of surface water, sediment and tissues
in support of an ecological risk assessment. Surface water metals
were sampled and analyzed using “clean” techniques, i.e. Class 100 clean
hood conditions, according to Method 1669. Additional water analyses
included cyanide, hexavalent chromium, total suspended solids and hardness.
Sediments were analyzed for metals, physiologically available cyanide (PACN),
hexavalent chromium and acid volatile sulfide/simultaneously extractable
metals (AVS/SEM). Fish tissue, mussels, clams, invertebrates and
aquatic plants were analyzed for metals. The fish species included
large mouth bass, pumpkinseed sunfish and yellow perch. Fish tissue
analyses were conducted on whole body, fillets, and livers. Various
species of aquatic plants were analyzed either as stem/leaf or root samples.
Deer Island Western Shoreline
Hydrocarbon Source Evaluation, Boston Harbor, Massachusetts. Confidential
Client. Sample Preparation Supervisor.
Woods Hole Group conducted
an ecological assessment of an intertidal shoreline area on Deer Island
in Boston Harbor, Massachusetts. Mussel tissue and sediment were
analyzed for alkylated and priority pollutant PAHs to identify the source
of hydrocarbons at the impacted site and to support a site ecological risk
characterization. In addition to sample collection, the assessment
included a semi-quantitative bioassessment survey of the intertidal biota
at the impacted and reference sites. The tissue analysis required
low parts-per-billion detection limits for the PAHs to satisfy risk-based
data quality objectives. Advanced fingerprinting diagnostic techniques
were used to identify the source of PAHs in the sediment and tissue residues.
Results of the study indicated that PAHs in impacted site bivalves contained
a large petrogenic component superimposed on a pyrogenic background observed
at the reference sites. The PAH concentrations found in the sediment
were determined not to be a risk to the intertidal bentic resources.
Ten Harbors Program, New
England Coastal Harbors. Confidential Client. Project Manager.
Woods Hole Group has analyzed
sediment and tissues in support of the Ten Harbors Program implemented
by the U.S. Army Corps of Engineers New England District. More than
90 sediment samples have been analyzed in seven sample delivery groups
for PAH (NS&T/EMAP list), PCB congeners (NS&T/EMAP list), pesticides,
metals, and TOC. Results have been reported on a 28-day turnaround
time in Level IV data packages, suitable for full data validation and with
an electronic data deliverable. As part of this program, more than
100 tissue samples (bivalves and amphipods) have been analyzed and reported
for PAHs and selected metals.
South Weymouth Naval Air
Station Remedial Investigations, South Weymouth, Massachusetts. Confidential
Client. Sample Preparation Supervisor.
Risk assessment and confirmatory
analyses were performed for a fuel farm and UST remediation at the Naval
Air Station in South Weymouth, Massachusetts. Analyses included TCL
VOC, SVOC and Pesticide/PCB, TAL Metals and waste characterization.
In addition, MADEP Methods for VPH/EPH, lead, copper and PCB results with
72-hour turnaround time were provided. Full Level IV, CLP-like data
packages suitable for data validation were provided for most analyses.
Gloucester Harbor Monitoring
Program, Gloucester, Massachusetts. Confidential Client. Sample
Preparation Superivsor.
In support of the City of
Gloucester, Massachusetts’ 301(h) Outfall Monitoring Program, Woods Hole
Group Environmental Laboratories is providing low-level measurements of
volatiles (Method 8260B modified), semivolatiles (Method 8270C modified),
pesticides/PCBs (Methods 8081/8082 modified), phenols, metals, cyanide,
grain size and TOC in marine sediments. The project-specific detection
limits were developed to permit ecological risk assessment using sediment
quality guidelines.
Waste Oil CERCLA Site,New
Hampshire. Confidential Client. Project Manager.
In support of an EPA Superfund
site remedial investigation, Woods Hole Group analyzed more than 300 soil,
groundwater, surface water and sediment samples. Sediments were analyzed
for ultra-trace level PAHs, pesticides, metals and acid volatile sulfide/simultaneously
extractable metals (AVS/SEM). Required analyses for the other matrices
included volatile petroleum hydrocarbons (VPH), extractable petroleum hydrocarbons
(EPH), TAL metals, pesticides, PCB Aroclors and TOC. Level IV data
packages were reported and validated, by a third party, along with project-specific
electronic data deliverables.
Caspian Sea Ecological
Baseline Study, Caspian Sea. Confidential Client. Sample Preparation
Supervisor.
In support of an ecological
baseline study for an international oil company, Woods Hole Group Environmental
Laboratories analyzed marine sediments and seawater samples for petroleum
hydrocarbons, polynuclear aromatic hydrocarbons (PAHs), polychlorinated
biphenyls, and total phenols. In order to provide meaningful baseline
measurements, alumina cleanup and gas chromatography with flame ionization
detection was employed for petroleum hydrocarbon measurements to provide
reporting limits on the order of 1 mg/Kg without interference from non-petroleum
hydrocarbons. Selected samples were analyzed for PAHs by gas chromatography/mass
spectrometry with selected ion monitoring. Data will be used for
comparing sediment and water column measurements from future monitoring
surveys.
