About  SETL

Sinotech Environmental Technology, Ltd. (SETL) has dedicated in site assessment, soil and groundwater investigation, and contamination remediation since 1990, persistent in quality assurance, technology innovation and sustainable customer relationship.


SETL provides comprehensive professional services includes: environmental site assessment (ESA phase I and phase II), geology and hydrogeological survey, feasibility and pilot study for contaminated site remediation, planning and design, construction and O&M, risk assessment, life cycle analysis (LCA), brownfield planning, green and sustainable remediation (GSR) practices

More than two decades, SETL continuously accumulates experience and reputation in cooperating with numbers of clients in contaminated site investigation and remediation. Clients comprise government and private corporation, such as Taiwan EPA and EPB, petrochemical factories, electricity suppliers, gas stations, steel foundries, etc.


Customized and qualified site conceptual model (SCM) can be effectively constructed through the cooperation of SETL experts and the application of innovative technologies (e.g. numerical geological and risk assessment model). Comprehensive services are realized as more than 20 years experience in site remediation, such as planning, O&M, monitoring and so on. Furthermore, we are the leading company for green and sustainable remediation consulting in Asia area.

Breakthrough in Petroleum- Contaminated Sites Remediaiton

Small Heading

Example: Grand Pacific Petrochemical Corporation

I'm a paragraph. Click here to add your own text and edit me. It's easy.Soil and groundwater in this site were contaminated by BTEX. SETL design and implement the remedy which includes AS, SVE, ISCO, Surfactant Flushing and bioremediation.

Small Heading Refinery

Example: Chinese Petroleum Corporation (CPC)

This site is located in Kaohsiung, Taiwan. Major products are ethylene, ethyne, propylene, benzene, xylene etc.. Soil were contaminated by BTEX and TPH. Groundwater were contaminated by BTEX, TPH and naphthalene. SETL design and plan the remedy, including AS, SVE, ISCO, oil skimmer, surfactant flushing and excavation.

Gas Stations

Examples: CPC, Mech Smile Inc. and National Petroleum Corporation

There are about 2,300 gas station in Taiwan. Contamination was often caused by the leakage of pipeline or UST, and the contaminants are BTEX, TPH(gasoline or diesel). SETL design and implement the remedy for our clients, the technics we often adopted are SVE, AS, excavation, biopile and ISCO.

Military Sites

Examples: Ministry of National Defense (MND)

SETL offered environment solutions and consultation to MND. Many army sites are contaminated by TPH. SETL plan and implement the off-site soil disposal. The soil was transported to cement or brick kilns to be as materials.

Long-range Pipeline Site

Example: CPC

Contamination in this site was caused by man-made destruction to the pipeline, resulting in the oil spraying to the soil and permeate down to groundwater. SETL plan the remedy including off-site disposal and ex-situ bioremediation for contaminated soil and enhanced in-situ bioremediation for contaminated groundwater.
