Ambient Air Monitoring Ambient air monitoring in Georgia provides information on measured concentrations
of criteria and non-criteria pollutants at selected locations. Criteria pollutants are those which a standard has been adopted by the U.S. Environmental Protection Agency. Non-criteria pollutants, while having no standard, provide useful information on the quality and content of ambient air. The monitoring network contains 46 monitors for criteria and 50 monitors for non-criteria pollutants.
The current Georgia Air Sampling Network ( G.A.S.N.), is comprised of 96 monitors at 70 locations in 32 counties. Monitoring takes place year round with the exception of ozone, which is sampled from March through November.
The monitoring network is composed of State and Local Air Monitoring Stations (SLAMS), National Air Monitoring Stations (NAMS), and Special Purpose Monitoring (SPM). During 1994 the network contained 13 NAMS, 16 SLAMS, and 61 SPM stations.
The number and location of the individual sites vary from year to year, depending on a variety of reasons which include: availability of long term space allocation; citizen complaint; regulatory need; etc. Once the site is established, it is our purpose to monitor for long term trends.
In general, the basic monitoring objectives that govern the selection of sites are: 1) to determine the highest concentration expected to occur; 2) to determine representative concentrations in areas of high population density; 3) to determine the impact on ambient pollution levels of significant sources or source categories; 4) and to determine the general background concentration levels.

TOTAL SUSPENDED PARTICULATE 1994 MONITORING NETWORK
In 1987 the particulate standard was changed from Total Suspended Particulate to a PM-10 Standard, ( particles with an aerodynamic diameter of 10 microns or smaller). In 1994 Georgia operated 40 TSP monitors in 22 counties acting as surrogates for PM- IO monitors. There were no excessions of the particulate standard in 1994 utilizing the TSP method therefore the PM-IO standard was met. A five year analysis of TSP annual means shows a downward trend in concentrations.

LEAD 1994 MONITORING NETWORK
Lead was monitored in 11 counties in 1994. There were no excessions of the standard. A twenty year analysis of maximum quarterly concentrations revealed a significant reduction in lead concentrations. This reduction was due mainly to the elimination of lead in gasoline. The emphasis in lead monitoring has shifted from mobile to stationary sources and a reconfiguration of the network will be forthcoming. This shift is evident in the 1994 Maximum Quarterly Composite graph where higher concentrations are seen in Columbus. Three sites are located in the vicinity of a secondary lead smelter.

ACID PRECIPITATION 1994 MONITORING NETWORK
Acid precipitation was monitored in 6 counties in 1994. The Air Protection Branch operated 3 of these sites and the remainder were operated by the Georgia Forestry Commission. There are no national or state standards for acid precipitation. A 5 year analysis of the data reveals no obvious trends.

TYPES OF SAMPLING METHODS

TOTAL SUSPENDED PARTICULATES (Manual) Samples are collected on 8" x 10" pre-weighed fiberglass filters with a high-volume sampler for 24 hours. Gravimetric gross particulate analysis is performed on all samples after collection. (method number 91)
LEAD (Manual} Samples are collected on 8" x 10" pre-weighed fiberglass filters with a high-volume sampler for 24 hours. Atomic absorption analysis is then performed on the samples.(method number 92)
SULFUR DIOXIDE (Continuous) Continuous analysis for sulfur dioxide is accomplished with the use of pulsed fluorescence (U.V. Light) method. (method number 20)
NITROGEN DIOXIDE (Continuous) Continuous analysis for nitrogen dioxide is accomplished with the use of ozone phase chemiluminescent method. (method number 074)
CARBON MONOXIDE (Continuous) Continuous analysis for carbon monoxide is accomplished with the use of non-dispersive infrared analysis and gas filter correlation methods. (method number 11)

61
OZONE {Continuous) Continuous analysis for ozone is accomplished with the use of U.V. photometric method. (method number 14)
PARTICULATE MATTER 10 MICRON {PM-10) Samples are collected on microquartz fiber filters with a PM-10 sampler for 24 hours. Gravimetric analysis is performed on all samples after collection. (method number 63)
NITRIC OXIDE Continuous analysis for nitric oxide is accomplished with the use of ozone phase chemiluminescent method. (method number 074)
OXIDES OF NITROGEN Continuous analysis for oxides of nitrogen is accomplished with the use of ozone phase chemiluminescent method. (method number 074)
ACID PRECIPITATION Samples are collected weekly and analyzed gravimetrically and also for acidity and conductivity. Further analyses are performed for selected compounds.
