Surface and groundwater investigation and remediation
On-site analysis and instrumentation
Acid mine drainage control and neutralization
Tailings management and in-situ soil remediation
Hydrocarbon degradation and modeling
GIS (geographic information system) mapping and modeling
Mine water treatment and disposal (design and construction)
Because of the incredible diversity of industrial sites
and their concerns,
Walker & Associates have developed solutions to
their delineation,
sourcing and remediation.
Some of the services we have
provided to clients are:
· In situ methods of groundwater
and soil clean-up
— — Fenton's
reagent
— — CrVI reductants
— — Ozonation
· Site reclamation Of surface
and gr4oundwaster and soils
· In situ hydrocarbon destruction
· Isotope fingerprinting
· Nickel and metal migration from drilling
muds
· Water disposal assessments
· Sediment and chemical dating
· Forensic analysis
· Litigation support
To meet NEPA, CEQA and SHPO standards pertaining to
cultural
resources we have on staff a Cultural Anthropologist.
This position
insures the following tasks are accomplished in accordance
with
state and federal mandates:
· Archival and literature review
· Title and deed searches
· Evaluation of sites
· Inventory of pre-historic and historic resources
· Archaeological investigations, when necessary,
· are conducted in a manner to enhance historical
· and archaeological
databases allowing
· remediation and
engineering efforts to continue.
With upcoming legislation in California and other states
pending, farmers will need to characterize and control
the chemistry of field runoff. Walker and Associates’
experience in handling and treating toxic and non-toxic
pollutants and design of passive treatment systems will
serve the agricultural community to comply to these
new standards.

Walker & Associates now provides direct services
to many clients in the golf course construction, maintenance
and remediation issues. Some of our clients include
Saddle Creek Golf Course, Spirit Ridge Project, Twelve

Water quality surveys
In-situ water treatment systems, passive and powered
Water recycling protocols and real time monitoring
devices
Cultural and archaeological surveys
Selection criteria for turfgrass types
Pesticide and nutrient management
Wetlands delineation and mitigation

3D visualization of landscape architecture
Best management practices
Environmental impact reports
Our principal, William
J. Walker, Ph.D., co-authored
the book, Golf Course Management and
Construction- Environmental Issues for the USGA.
Chemical and physical data collected can be correlated
with geographic location to provide visual and statistical
models to better understand the
environmental dynamics of many systems.
With the help of Autocad based
GIS (Geographic Information System), models can be
changed or tested to provide the best management practice
to apply to each unique situation that applies.
Permitting
and Litigation Support
|
|
An integral part of many WAI projects is working with
state
and federal regulatory agencies to develop effective
and appropriate
goals for site remediation and closure. We strive to
apply meaningful
chemistry and geochemistry to each project to achieve
cleanup goals
that meet regulatory approval and are attainable given
site background
and history.
Our understanding of the regulatory approval process
also enables us
to provide regulatory compliance and litigation support.
Using forensic
geochemistry and geologic background evaluation, we
can resolve
allocation and sourcing issues. We also provide support
in developing
and implementing cost effective monitoring programs
for long term
regulatory compliance.
Training
and Documentation
|
|
Walker and Associates has the capability to produce
videos and other training materials for clients who
need to train their employees in field-testing and other
endeavors.
We can also document all phases of our work in field
or laboratory to illustrate techniques or allow clients
to actually see progress in any project.
