People Also Ask about

Which class of contaminants are most likely to be remediated from groundwater using a natural attenuation strategy?

Target contaminants for natural attenuation are VOCs and SVOCs and fuel hydrocarbons. Fuel and halogenated VOCs are commonly evaluated for natural attenuation. Pesticides also can be allowed to naturally attenuate, but the process may be less effective and may be applicable to only some compounds within the group.

What natural contaminants can groundwater contain high natural concentrations of?

Groundwater moving through sedimentary rocks and soils may pick up a wide range of inorganic compounds such as magnesium, calcium, and chlorides. Some aquifers have high natural concentrations of dissolved constituents such as arsenic, boron, and selenium.

What are the three categories of groundwater contaminants?

Overuse, biological contaminants (e.g., manure and septic systems), and industrial pollutants (e.g., pesticides, petroleum products, and industrial solvents) can all threaten groundwater supply and quality.

Can natural attenuation be considered as an effective solution for soil remediation?

Yes. Monitored Natural Attenuation (MNA) is an important part of today's remediation industry: • MNA is used at many sites as the primary or sole remediation technology. MNA has been adapted for the purpose of “Enhanced Attenuation”1 (EA) that provides a bridge between aggressive source zone treatment and MNA alone.

What is natural attenuation of groundwater contaminants?

3.1 Natural Attenuation. MNA is the monitoring of natural processes in soil and groundwater environments that act without human intervention to reduce the mass, toxicity, mobility, volume, or concentration of contaminants in those media [18].

What does monitored natural attenuation mean?

Monitored natural attenuation (MNA) consists of a range of naturally-occurring in situ physical, chemical, and biological processes that attenuate contaminant concentrations in groundwater to achieve remedial goals within a reasonable timeframe, and protect human health and the environment.

What are the five natural attenuation processes?

Natural attenuation relies on subsurface processes such as dilution, dispersion, sorption, volatilization, and biodegradation to effectively reduce contaminant toxicity, mobility, or volume to levels that are below drinking water guidelines (Wiedemeier et al., 1995).

What are the most common methods of groundwater remediation?

Ground water remediation techniques span biological, chemical, and physical treatment technologies. Most ground water treatment techniques utilize a combination of technologies. Some of the biological treatment techniques include bioaugmentation, bioventing, biosparging, bioslurping, and phytoremediation.

The MONITORED NATURAL ATTENUATION PROGRAM APPLICATION is a formal request for the approval to utilize natural processes to reduce environmental contaminants at a specific site while monitoring the effectiveness of these processes over time.

Who is required to file MONITORED NATURAL ATTENUATION PROGRAM APPLICATION?

Parties responsible for the contamination of a site, such as property owners, operators, or responsible parties identified under environmental regulations, are required to file the MONITORED NATURAL ATTENUATION PROGRAM APPLICATION.

How to fill out MONITORED NATURAL ATTENUATION PROGRAM APPLICATION?

To fill out the MONITORED NATURAL ATTENUATION PROGRAM APPLICATION, one must provide details about the site, describe the contaminants present, outline the proposed monitoring plan, and include any relevant data or assessments that support the use of natural attenuation strategies.

What is the purpose of MONITORED NATURAL ATTENUATION PROGRAM APPLICATION?

The purpose of the MONITORED NATURAL ATTENUATION PROGRAM APPLICATION is to seek regulatory approval to manage and remediate contamination through natural processes while ensuring that the sites remain safe and do not pose risks to public health or the environment.

What information must be reported on MONITORED NATURAL ATTENUATION PROGRAM APPLICATION?

The MONITORED NATURAL ATTENUATION PROGRAM APPLICATION must report information such as site history, contamination details, natural attenuation processes expected to occur, monitoring plans, and expected time frames for remediation.
