in support of NEPA environmental assessments for
- Release of lands
from government and industrial uses to the public.
- Relicensing
of hydropower dams.
- Siting of waste disposal and wastewater treatment
facilities.
- Forest and watershed management.
ENVIRONMENTAL AND WATER RESOURCES ENGINEERING
We have experience in water resources assessment and
environmental engineering, including
- Assessing the viability of groundwater and surface water resources.
- Modeling
in support of RCRA Feasibility Investigations and CERCLA Feasibility
Studies.
- Surface water modeling in support of
- NPDES permit limits.
- Non-point source management decisions.
- Watershed modeling in support
of
- Watershed restoration and conservation funding prioritization.
- Forest
management and reservoir release optimization.
RADIOLOGICAL PERFORMANCE
ASSESSMENT
- We have supported the development of Performance Assessments
(PAs) under DOE Orders 5820.2A and 435.1, and under 40 CFR 191 for the
disposal of
radioactive
wastes.
- We have compared the performance of DOE radiological disposal technologies
and sites across the DOE complex in support of radioactive waste management
decision making by the National Governor’s Association.
ENVIRONMENTAL
MODELING IN GIS
Our staff have Geographic Information Systems modeling
experience in
- Environmental data assessment and modeling using the
GIS platforms MapInfo and ArcGIS.
- Watershed delineation and classification.
- Groundwater advection-dispersion
modeling of contaminant transport.
- Watershed restoration and conservation
prioritization.
CONCEPTUAL MODELS
We have used conceptual models as a way of communicating
and describing complex fate, transport, and exposure processes with
stakeholders.
MODELING TOOLBOX
Our toolbox of standard modeling software includes Multimed,
MEPAS, HELP, RESRAD, WASP, QUAL2e, HSPF, Surfer, S-Plus,
SAS, PRSYM, RiverWare,
ArcInfo
GRID, the
HEC models, GoldSim, GeoEAS, MODFLOW, GWSIM, ShowFlow, HSSM,
MOC, TWOLAY, and FTWORK.
SOFTWARE DEVELOPMENT
At Neptune and Company, we specialize in developing Web-based
Open Source
solutions to statistical and environmental problems. We have successfully
used Apache Cocoon, Java, XML, and R to deploy a number of Web-based
solutions. We have also developed standalone graphical applications
in
statistics and database management.
