Contaminated land is a health concern if the public is exposed to toxic chemicals through the impacted soil or groundwater. Leakage of underground oil or chemical storage tanks due to corrosion or spillage over bare soil result different level of severity of land contamination.
Therefore, it is necessary to assess the level of contamination by collecting soil and groundwater samples for laboratory analysis before re-development. CMA Testing provides clients a wide range of testing services that adhere to applicable standards.
According to Environmental Protection Department (EPD), Risk-Based Remediation Goals (RBRGs) tailor the extent of remediation required to the level of risk under certain land uses. The test parameters in RBRGs are as below.
| VOCs | SVOCs | Metals |
| – Acetone – Benzene – Bromodichloromethane – 2-Butanone – Chloroform – Ethylbenzene – Methyl tert-Butyl Ether – Methylene Chloride – Styrene – Tetrachloroethene – Toluene – Trichloroethene – Xylenes (Total) | – Acenaphthene – Acenaphthylene – Anthracene – Benzo(a)anthracene – Benzo(a)pyrene – Benzo(b)fluoranthene – Benzo(g,h,i)perylene – Benzo(k)fluoranthene – bis-(2-Ethylhexyl)phthalate – Chrysene – Dibenzo(a,h)anthracene – Fluoranthene – Fluorene – Hexachlorobenzene – Indeno(1,2,3-cd)pyrene – Naphtalene – Phenanthrene – Phenol – Pyrene | – Antimony – Arsenic – Barium – Cadmium – Chromium III – Chromium VI – Cobalt – Copper – Lead – Manganese – Mercury – Molybdenum – Nickel – Tin – Zinc |
