Our commitment to quality and performance has led to our involvement and testing in hundreds of real-world situations. The following library of reports, presentations, specifications, approvals and other similar documents provide you, our customer, the transparency and dependable assurance that is expected from Soilworks.
During asbestos remediation at the Hunters Point Power Plant, air monitoring protocols were implemented to evaluate and control airborne naturally occurring asbestos (NOA) levels. On-site dust suppression was critical to keeping fiber concentrations below regulatory trigger levels, especially during high-impact activities such as underground demolition and soil excavation. Soiltac, a polymer-based soil adhesive manufactured by Soilworks, was used effectively as a preventative and responsive dust control measure. It was applied following elevated asbestos readings and before forecasted rain events to seal exposed soil surfaces and reduce airborne contaminant risks.
The report confirms that multiple applications of Soiltac played a key role in suspending particulate matter migration during site disturbances and adverse weather. This aligns with its known performance for creating erosion-resistant, crusted soil surfaces in environmental remediation and hazardous waste management projects. For professionals managing dust and contamination control in similar high-sensitivity industrial cleanup operations, Soilworks’ polymer technologies deliver proven results with rapid response capabilities and EPA-compliant formulations.

Hunters Point Power Plant Cleanup ‐ Air Monitoring Results
Following is an overview of the air monitoring results for airborne naturally occurring asbestos that PG&E collected at the former Hunters Point Power Plant site from June 20 to July 1, 2011, on days that work was being conducted. For this period, there were two days with readings above the Trigger Level, a conservative threshold at which additional dust controls will be implemented. A summary of the readings is below.
June 20 to June 24, 2011
1: Activities taking reading: Underground demolition and fence‐ line sampling.
Actions taken: Underground demolition work in the area was suspended on June 27. On June 25, Soiltac (a soil adhesive) was applied to help reduce potential for airborne NOA. One more water truck was added to support fence‐line soil sampling, a low impact activity, and the backfilling of excavations with clean soil. All personnel were reminded of the established dust measure protocols.
June 27 to July 1, 2011
1: Activities taking place in areas of reading:
Actions taken:
The site incurred an unusual rain event in which 0.89 inches of rain was received. The following actions were taken. All soil disturbing activities for the following day (6/30/11) were suspended until TEM results were received for June 29. In the future when rain events are in the forecast, an additional application of Soiltac will be applied to all areas.
