Phase I ESA - (Environmental Site Assessment)
RENG professionals have performed Phase I ESAs throughout Nevada and Northern California in accordance with ASTM Standard E-1527-13 and the EPA’s All Appropriate Inquiries Rule.
Project activities include:
- A site visit and visual assessment of adjacent properties
- Historical research; governmental database research
- Determination of the presence or absence of Recognized Environmental Conditions
- Preparation of a summary report.
In accordance with regulatory requirements, Phase I ESAs that take place in Nevada are performed by a RENG Certified Environmental Manager.
Phase II - Investigation / Sampling
Phase II investigations can consist of testing for a suspected environmental issue, delineating the horizontal and vertical extents of contamination, or collecting samples to prove the absence of contamination. RENG staff has performed vapor, surface water, groundwater, and surface and subsurface soil sampling following State and Federal guidelines while investigating petroleum hydrocarbons, petroleum-based solvents, chlorinated solvents, metals and pesticides. Samples are delivered to State-certified laboratories for an independent analysis. Phase II reports describe the investigative activities completed as well as all analytical results. Conclusions are presented from the collected data. The report’s recommendations will discuss available options while weighing regulatory with economic concerns.
Phase III - Corrective Action
Our Phase III services consist of collaborating with all parties involved, including clients and regulatory authorities, to assess remediation options that consider timelines and costs as well as cleanup goals. RENG remediation experience has ranged from excavation and on-site encapsulation of contaminated soils to closure by risk-based analysis of impacted groundwater.

The potentiometric surface can also be mapped using a number of wells in order to determine the groundwater flow direction and magnitude.
