Las Vegas is located in the southern tip of Nevada along the Colorado River.
Situated in the desert environment, air, water, and visibility concerns arise
in response to nature's extremes, as well as human activities. The local,
state, and federal governments gathered together to form the Environmental
Monitoring for Public Access and Community Tracking (EMPACT) web site, an
online guide for residences to stay informed of the latest news in air, water,
and visibility concerns. The EMPACT site is published at www.empact-lv.org
. Air quality concerns many residences across the United States, including
the Las Vegas Valley. Situated in a basin, Las Vegas is geologically enclosed,
preventing proper air circulation to maintain a healthy atmosphere. Air quality
received the primary focus in the past because air pollution levels exceed
EPA’s unhealthful daily standards. In response to the news, a web site was
developed by the Clark County Health District’s Air Quality Division to display
the latest news in air pollution readings, as well as access historical data.
The development of the web site utilized the power of database to handle large
quantities of data for easy access and reliability. CGIs were used as the
interfacing medium to obtain the data when the user to the web site requested
the specific data, as well as process new data that are updated every hour.
The completed web site is located at http://air.cchd.org/ . Pollen counts,
another issue more unique to the Las Vegas Valley, was also incorporated and
updated frequently during peak pollen seasons in spring and early summer.
In addition to the web site, the data collection systems were outdated and
required an update. The data acquisition systems involving LabVIEW are also
being developed with Visual Basic to complete the package.
