SAMPLING AND TESTING
Tewhey Associates has extensive experience in the proper
protocols for the collection and handling of water quality samples (e.g.,
from wells, surface water, effluent discharges, etc.). The technical staff
are knowledgeable in the selection of appropriate USEPA and Maine DEP
analytical methods and in the preparation of QA Plans. We have worked with
most of the private labs located in Maine and northern New England and with
the Maine Department of Human Services laboratory facility. Our
monitoring/sampling experience has included analyses for heavy metals,
inorganics, pesticides, PCBs, and, volatile and semivolatile organic
compounds. We have had extensive experience with the analysis and data
interpretation for petroleum hydrocarbons, PAH compounds and
pentchlorophenol (PCP). We compile data in a tabulated format and often
present the results in terms of graphs and figures which precent a clear and
concise understanding of the study findings. The size of our monitoring
projects has ranged from one time sampling for small Phase 2 Environmental
Assessments associated with property transfer to multiple round, multi media
sampling at large industrial RFI sites. Some examples of our monitoring
experience are provided below.
Monitoring and Data Evaluation at an RFI Site in Sanford, Maine.
