SITE INVESTIGATION & REMEDIATION
We help clients manage risk associated with current and historical releases of oil and hazardous materials including PCBs:
IRWIN follows the required All Appropriate Inquiry standard to identify Recognized Environmental Conditions during a Phase I Assessment. If needed, we then use logical and cost effective steps to engineer a remedy to reduce or eliminate the risk to acceptable levels. We understand that our Clients may appreciate the science and technology involved but most often they are most concerned with compliance, cost and schedule. The regulations and acronyms are numerous and complex but we see our job is to explain in plain language what needs to be done and why. Services include |

Phase I Site Assessments |
|

The Phase I Assessment performed to the All Appropriate Inquiry Standard provides the User with certain Landowner Liability Protections. IRWIN follows the strict guidance set forth in the ASTM Standard Practice E1527-05 which conforms to the federal requirements of 40 CFR Part 312 passed in November of 2006. This level of assessment is designed to identify Recognized Environmental Conditions, which, if found, might warrant further investigation. IRWIN has completed hundreds of site assessments in areas such as: |

Subsurface Investigations & Remediation |

We focus on data collection for (1) defining an exposure pathway or level of risk or (2) characterizing a dimension or physical/chemical characteristic of the impacted media that will be relevant to engineering a remedy. Our President is a member of the E50 ASTM Committee for GREEN REMEDIATION putting us at the leading edge of remediation for the 21st century. Our innovative strategies and project management experience have played into the effective implementation of remedies at more than 125 properties including a variety of environmental conditions and contaminants: |

IRWIN has conducted bench scale testing and pilot scale studies of remediation technologies for proof of concept and implemented them in the field. This has led to adaptation and improvements on existing technologies that have saved our clients money with implementation of full scale projects. We know that past releases can be expensive so we help clients design to prevent or control system failures. See Contingency Planning. |

LSP Services (Licensed Site Professional) |
 |
||
The Commonwealth of Massachusetts has privatized site cleanup by licensing select individuals based upon experience and examination to oversee spill response and clean-up of contaminated real estate. These people are called LICENSED SITE PROFESSIONALS. IRWIN has a fully licensed, experienced LSP on staff including the current President of the LSP Association, J. Andrew Irwin. Spill response and remediation of contamination in Massachusetts must be done in accordance with the Massachusetts Contingency Plan (MCP), an extensive set of regulations. This is a performance based program. It requires judgment and experience on the part of the LSP as to what scope of assessment is appropriate on a site-specific basis. IRWIN takes clients through the MCP process from Immediate Response Actions all the way to Phase V Remedy Operation Status as needed. We provide personalized attention for every site and we are available for emergency response. Our site assessment activities are carefully planned to maximize their efficiency. We consider risk assessment and remediation system design requirements early on in the process. We use highly qualified and licensed subcontractors for sample collection and laboratory analysis of samples from sites where hazardous materials are known or suspected. |
