Environmental Site Assessment

Trinity Environmental has conducted hundreds of site assessments of commercial and industrial properties involved in real estate transactions or sites that have experienced a reportable release of hazardous waste or hazardous constituents. We perform Phase I and Phase II site assessments in accordance with ASTM E1527-13 and ASTM E1903-11, respectively, and utilize the information gathered to develop response action plans and remediation cost estimates, if necessary, under Phase III.

First, under Phase I, we gather in an effort to identify any recognized environmental conditions (RECs) that could be cause for concern at a site. Then, if warranted, we may collect soil and groundwater samples and other site-specific data needed to evaluate the significance of the RECs under Phase II. This data allows us to develop a conceptual site model that allows us to assess potential risks to human health and the environment.

At sites that have been impacted by a reportable quantity spill, the assessment data we collect provides the context needed to determine if a site can be remediated to achieve background values (e.g. under Texas Spill Rules) or if risk based corrective action is more appropriate. At sites in Texas, our findings are documented in reports for submittal to the Texas Commission on Environmental Quality (TCEQ) as a simple closure report or an Affected Property Assessment Report (APAR) under the Texas Risk Reduction Program (TRRP). The Louisiana Department of Environmental Quality (LDEQ) has a similar process under the Risk Evaluation Corrective Action Program (RECAP).

Our field personnel are HAZWOPER trained, have confined-space entry training, and are trained to work at sites that require the use of respiratory protection.
