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.
