Environmental Services
All of our services are custom designed to meet our client's specific needs. You may need someone to handle your entire project from beginning to end, or just lend support to your staff.  Our only goal is to produce the best remediation systems in a cost effective and timely manner.

HFG designs systems that work 

We custom design the systems needed to apply the following standard technologies to your remediation project.

Our R&D department is at your servece to help you develop new remediation technologies.

Biological Treatment
Chemical Treatment
Biological Augmentation
Air Sparge
Dry Vapor
Wet Vapor
Phase Seperation

Micro Filtration
Carbon Filtration
Thermal Oxidization
Catalytic Oxidization


HFG performs all assessments with a singular purpose.  That is to identify and apply the best availble technology "BAT" that will enable you to close out your site.

It is never too early or too late to take advantage of our remediaiton assessment services.  The scope of our assessment services are custom designed to the current phase of your project.

Phase I:  Using your Phase I data we can provide you with a list of viable technologies prior to commiting to any further investigation.  Having this advanced     knowlege will enable you to develope a Phase II scope of work with a purpose.

Phase II:  Using your Phase II data we can begin to narrow down your remediaiton options.  Should you already have a technology in mind, this is the time to consider a pilot test.

Phase III: This is the most labor intensive phase in developing a remediation plan.  Only the most promising options should be submitted for this evaluation.

Each option that makes it to Phase III is evaluated for the following criteria.

1.  Availablility:       Is the technology readily availble within a reasonable distance from the site?
                               Is the means for installing the technology availble within a reasonable distance from the site?
                               Will specialized equipment have to be developed by our R&D department to employ the technology? 
2.  Effectiveness:    Will the selected technology enable you to close out the site in a reasonable time period?
                               Will an additional technology need to be employed in order to polish off low concentrations?
2,  Initial Cost:        What is the initial cost of installation?
                               What is the cost of start-up operations?
3,  Operating Cost: Will the technology generate a utility bill?
                               Will the technology generate O&M costs?
                               In the case of Bio/Chemical treatments, will the treatment need to be repeated?
4.  Reliability:          Does the system have a life expectency greater that the projected duration of the project with normal maintenance.
                               Will the system consistantly perform it's designed function for the duration of the project with normal adjustments.
                               Can the system adapt to changing site-specific conditions with normal adjustments.
6.  Operations:       Can all accepted industrial standards be applied to the installation of the system?  These industrial standards are applied to insure the
                               safety  and effectiveness of the operator.
5,  Diagnostics:      Can the assigned operator easily identify malfunctions during a normal O&M visit.
6.  Repairablilty:     Can the system be easily repaired by an operator with standard training?
7.  Monitoring:        Can all operating parameters be accurately monitored?
8,  Footprint:           Will there be an adverse impact to the site by using the technology?
9.  Regulatory:        Other than the DEP, will the technology generate any sampling and reporting requirements?
                               Will the system require any permitting?
10.  Stealth:            Can the technology be imployed without devaluating the apperaance of the site or attracting undue attention to the operations?
Phase IV:  Assessments performed during this phase are divided into two catagories.  Pre-construction (before final plans are submitted for construction) and post-construction (after final plans are submitted for construction).  The only difference between the two is the method for implementing engineering changes.

This assessment is performed using the same criteria outlined in Phase III

1.  Pre-concstuction:   Any design changes can be included in the origional drawings.

2.  Post-construction:  Any design changes will be submitted as an "engineering change".


HFG follows a strict protocol when designing our systems.  All systems, large or small, undergo the same process to insure a sucessful remediation project.

HFG will not hand over any part of the design process to the decression of a vendor.  When our design is complete. there is no room for vendor substitutions.

The process begins project clarification.  Our pencil does not touch the paper until our engineer and your project manager are clearly on the same page.

We have extensive experience communicating with project managers from all academic backgrounds and levels of experience.

1.  Data Review:       All data collected during our review process is screened for acuracy and reliability.
2,  Communication:  Data that does not make sense is marked for clarification and communicated to the client.
3.  Resolution:          No problem is considered resolved until there is a clear "meeting of the minds" between our engineer and your project manager.

HFG will create a draft plan and submit it to you for review.

Upon your approval, the plan is forwarded to our drafting department.


Not all systems are created equally

The nature and complexity of the system will determine what drawings are needed to clarify the project.  Too many drawings will tend to confuse the reader.

Certain drawings and diagrams of specific components will be obtained from the manufacturer and edited to reflect your specific installation.  We find this process to be the most efficient and cost effective.

In addition to the standard drawings HFG is offering a "virtual site plan".  Some of the features of the virtual site plan are:

1.  Orthographic view of the entire site (depending on size)
2.  Zoom range of 0 to 2500%
3.  Ability to store ongoing data directly onto the drawing
4.  Ability to frame and print any part of the drawing


System specifications is the most important companion to our system design. Without a complete set of specifications your system is vunerable to numerous substitutions that could render the entire system ineffective or even inoperable.

Specifications are the fine print that holds the equipment vendor responsible for every component they install into your system.

HFG provides your with a set of specifications that clearly defines what is going into the system and where substitutions are and are not allowed.

This is a legal document that protects our clients from the "buyer beware defense". 


HFG does not design any ststem that we don't completely understand.  We have the ability to install, diagnose, operate, maintain, and repair each and every component that goes into the system.  If a pump goes down or a guage fails, we have the technical knowlege to repair it.

We are availble to oversee every step of the installation or brief your project manager on all of the inspection points refered to in the specifications.

HFG has the technical knowlege to perform an entire installation.  However, we also have the wisdom to know that having the technical knowlege doesn't mean we have the skill.

Our expertise is best applied to selecting the skilled professionals with the experience to perform installations.

Our network of professionals include Industrial Electricians, Mechanical Contractors, Pump Contractors, Carpenters, Pipe Fitters, Welders.

Paying now for professional installations will save you thousands in down time or even a non-compliance citation.


HFG will generate a report documenting each stage of our work,

The report will include:
1.  Summary of all work performed by HFG
2.  Description of the system and it's specific function.
3,  Drawings generated by HFG.
4.  Specifications generated by HFG
5.  Equipment supplied by vendors and supporting documentation
6.  Tasks performed by sub-contractors and supporting documentation.
7.  O & M manual

Technical Support

HFG is availble to provide technical support for our systems and systems designed by others,

Technical support packages are custom designed to fit your need and the need of your specific system.

HFG will evaluate your system and prepare a support package for your consideration.


HFG will train your operator in the proper operation and maintenance of your system.

Training is usually performed during the "shake down run".  This is the period that offers the steepest learning curve and the fastest way to get your operator up to speed.
