Soil and groundwater monitoring are essential in assessing your environmental risk.
We want clients to always come to us when a problem arises because of their trust in us, our reputation, and the urgency in which we react to and solve their problems.

Remediation is defined by the Environmental Protection Agency as “cleanup or other methods used to remove or contain a toxic spill or hazardous materials.” Sierra Piedmont has designed, tested, installed and evaluated many soil and groundwater remediation systems. Sierra Piedmont stays abreast of the latest technologies by attending training sessions sponsored by theoretical and application leaders such as The Air Force Center for Environmental Excellence (AFCEE), The National Ground Water Association (NWGA)and Nielsen Environmental Field School.

Sierra Piedmont utilizes many different methods of remediation – all hinging on what is going to be the most efficient and cost-effective way to mitigate contamination.  Remediation can generally be divided into two categories – active and passive:

Active:
Active remediation requires human intervention to remediate contamination.  Processes include mechanical (such as excavation or encapsulation), chemical (such as peroxide or persulfate injection), manual separation (such as pump-and-treat or dual-phase remediation systems), use of biologic agents (such as microbes that metabolize contamination or plants that fix contamination in their wood), or flushing (such as surfactant flushing).

Passive:
Passive remediation relies on natural processes to remediate contamination.  This process is often called natural attenuation.  Passive remediation may be used at sites where no potential receptors are threatened and contaminant levels are low enough to reasonably believe that natural processes (such as dilution and/or biological ingestion) will reduce contamination to acceptable levels.
