levels.
Systems and methods for monitoring hazardous materials in the air, and more particularly
systems and methods for reducing hazardous conditions in environmental remediation sites, are
disclosed.
Brief of invention
The remediation of soils contaminated with hazardous materials is an important environmental
objective. In particular, the remediation of contaminated sites removed from the local community
a source of hazardous waste and recover the land for beneficial use. As a result, the remediation
process is an important and valuable component of the land management tool, and its use has
increased dramatically in the United States.
However, as beneficial as cure is, the process itself has inherent risks. In particular, hazardous
materials are present in the remediation of the site, which, although dangerous in themselves, are
often in a stable form and left; intact at low risk to the surrounding community. Sanitation often
requires the disposal of remediation materials from contaminated sites that cause subsoil soils are
disrupted. These subsoil soils may contain any amount of volatile hazardous materials, including
volatile and semi-volatile organic compounds (VOCs) and SVOCs, such as benzene and
polycyclic aromatic hydrocarbons (PAHs). The release of VOCs and COSV sanitation sites
poses a toxicity risk to the surrounding community, and the disturbance of the soil containing
these materials can cause air quality to be significantly degraded. Once released into the ambient
air, these compounds are free to move away from the remediation of the site and the local
community depending on weather conditions.
Although there are air quality measurement systems, these systems are generally separate
sampling devices the air normally used once an air quality problem is suspected. Therefore, these
systems are generally reactionary, providing information about the damage caused.
It would therefore be desirable to have a real-time system for monitoring the quality of the air
coming out of a site remediation to prevent or reduce the public health risks of surrounding
communities associated with on-site activities.
Summary of Invention
The invention provides air quality perimeter control systems that can establish background levels
of target pollutants in ambient air prior to commencement of sanitation activities. Systems can
develop corrective action levels to protect public health from dust remediation and vapors on the
property and can monitor and document ambient air levels of target pollutants during
remediation activities . As a result, the systems and processes used to assess the need for control
measures to reduce dust levels or containment of steam in the air at lower levels of concern
levels.
To this end, the systems and methods described herein may include a device for monitoring
hazardous materials in air comprising a gas detector for analyzing an air sample for the volatile
organic compounds and a dust detector for detecting particles in air Suspension in the air. The
systems may also include a data communication device which is,coupled to the gas detector and
the dust sensor and is capable of transmitting data signals via a data network. The apparatus may
also include an instrument gas treatment which is capable of identifying the types of volatile
organic compounds in an air sample. The systems may further include an alarm that will generate
an external notification that is representative of a volatile organic compound is at a concentration
greater than a designated concentration level. Similarly, the systems described herein may also
include an alarm for generating an external signal notification upon detection of powder levels
above an acceptable level of concentration of public health.
In one embodiment, the systems may be programmed so that an operator can select individual
volatile organic compounds being identified, monitored, or detected by the systems described
herein. In another embodiment, the systems may include controllers that are coupled to
communication devices that allow data and control access and monitoring systems from a remote
location.

threshold of a selected volatile organic compound which is representative of a protective
concentration of risk to human health. Similarly, the systems include mechanisms for designating
a threshold concentration of a powdered material which is representative of a concentration
based on risk to human health. The systems described herein may include hermetic housing for
enclosing the elements of the system and for providing an interior chamber having a controlled
interior environment.

AIR IMPACT EVALUATION
The impact assessment component of air quality research consists of calculating emissions from sources
within a process and predicting the impacts of air quality resulting from the release of these emissions.
The impacts of ambient air quality are determined by monitoring the specific parameters. The physical
impact is assessed by comparing the levels of concentration or deposition provided with available health
detection limits.
AIR QUALITY MANAGEMENT PLAN
The management of air quality planning can be carried out at the local or regional level. Therefore, they
can develop management measures to reduce the impacts of one or more sources of air quality. Our
experienced consultants identify the management measures that could be implemented in practice,
depending on the resources available to the Customer, with the main objective of implementing the
best available technology for a specific source of pollution.
