Monitored Natural Attenuation

MNA is becoming increasingly accepted as a viable and cost effective option, in certain situations, for the management of the risks associated with contaminated groundwater. MNA depends on demonstrating that natural processes are occurring at a rate that protects the wider environment and achieves remedial objectives within a reasonable timescale. It may form part of an overall remediation strategy involving active remediation measures such as source removal or containment. 

Telluric Land Remediation has the expertise to assess the viability of natural attenuation, to demonstrate that it is occurring and to verify attainment of the remedial targets. This is undertaken by:

• Demonstrating loss of contaminant mass in the field.

• Monitoring geochemical and biochemical indicators to establish that the contaminant concentration is reducing due to natural attenuation.

• Providing microbiological data to support the occurrence of biodegradation.
