Why Should I Hire a Consultant to Conduct an Audit?
If you suspect a violation may be present or you become aware that a facility should have been complying with a law but has not, a consultant can come in and offer environmental compliance solutions.

Phase I ESAs and Non-Scope Considerations
It is very important, and most times required, by lenders to have a Phase I Environmental Site Assessment (ESA) performed prior to a property transaction. The purpose of an ESA is to identify environmental risks associated with the property and to protect against liability related to existing site conditions. However, there are a number of environmental considerations which are outside the scope of a Phase I ESA; commonly referred to within an ESA as “non-scope considerations.” These additional...

Green Remediation
Green remediation is a term used to describe the process of considering sustainable environmental practices during remediation of contaminated sites. The United States Environmental Protection Agency (EPA) published a Green Remediation Technology Primer in April 2008 to provide “topical introductory information” relating to Green Remediation. The EPA defines green remediation as “the practice of considering all environmental effects of remedy implementation and incorporating options to maximize...

Environmental Analysis and Remediation - Why the tedious work is important
Intern Tyler
Hill's work has included entering new data in existing
tables while also updating previous information. The data tables
are of soil and groundwater sampling constituent concentrations. As
further remedial investigations are done, new data becomes
available which needs to be entered into our existing tables in
order to be compared with previous data. This task is often
meticulous and tedious, but it is important that the updates are
done correctly.

How Do You Investigate for DNAPLs?
When investigating for Dense Non-Aqueous Phase Liquids (DNAPLs), one must consider the following:
- Not likely to observe free product in subsurface
- Must not create new vertical migration pathways
- Need to be able to discretely sample multiple vertical zones
If you have questions regarding DNAPLs, contact August Mack Environmental at 800.579.0770 and ask to speak to one of our environmental remediation specialists.
Physical Properties of DNAPLs
- Immiscibility with water - they form separate ‘phases’, eg. Oil & water
- Low solubilities - DNAPL can’t dissolve quickly in groundwater: it may persist for decades before dissolving
- Relatively high densities - DNAPLs are denser than water, and can therefore sink beneath the water table, polluting the full thickness of an aquifer
- Low viscosities - allows rapid subsurface migration
- Toxicity - Many DNAPLs are suspected or...
