5.4.2.4 Playing Fields at the Community Park
During the baseball and soccer scenarios conducted on the playing fields at the Community Park, the START operated additional stationary high-flow air sample pumps at the Children’s Playground.
North Field Baseball Playing Field. The START conducted activity-based outdoor air sampling at the North Field on October 5. The START intended to collect soil samples to test the moisture level of the field prior to conducting the scenario, but this was inadvertently overlooked. The soil moisture samples were collected instead on October 7, 2004 (see Table 5-7: Moisture Levels in Activity Area Soils).
The START conducted activity-based outdoor air sampling at the North Field, according to the following scripted schedule:
- For the entire 2-hour scenario, one member of the sampling team simulated the activities of an adult/parent spectator walking and standing behind the backstop and sitting on the bleachers and in the dugouts. The intake for the air collection filter cassette worn by this sampling team member was set at a height of about 5 feet.
- For the first 10 minutes, another member of the sampling team drove an electric maintenance cart towing a steel drag mat around to groom the infield. The cart and drag mat are the same equipment the CSD maintenance staff use to groom the infields prior to games. Use of the cart and drag mat mimicked CSD infield maintenance procedures, except that the START did not wet the infield down, as would normally be done prior to dragging, in an attempt to capture the upper end of exposure levels. During the infield dragging, two other members of the sampling team sat in the dugouts, and another two members of the sampling team walked around the infield, occasionally within or near the cloud of dust created by the drag mat. The intakes for the air collection filter cassettes worn by these five sampling team members were set at a height of about 3 feet.
- For the next 20 minutes, the electric cart and drag mat were set aside, and these five members of the sampling team walked around in the infield and spectator areas and used hand tools to perform field grooming tasks. One member of the sampling team swept the dugouts, one swept behind the backstops near the spectator bleachers, one used a dirt rake on the infield dirt, one walked around the bases, and one used a dirt tamp to tamp around the pitcher’s mound and home plate.
- For the remaining 90 minutes, the five members of the sampling team simulating the activities of children alternately sat in the dugouts for 10 minutes then played baseball (infield practice) for 20 minutes; this pattern was repeated three times in the 90 minutes.
- During the last 30 minutes of infield practice play, a seventh member of the sampling team who was not wearing a sample pump entered the scenario to run bases and slide toward bases. This member of the sampling team was allowed to engage in more vigorous physical activity than the other members of the sampling team without having to worry about damaging the equipment or having the pumps fall out of the belts.

South Field Baseball Playing Field. The START conducted three baseball scenarios on the South Field at the Community Park. One scenario was conducted on October 5 (Baseball Scenario A), and two were conducted on October 6, 2004 (Baseball Scenario B and Baseball Scenario C). The START intended to collect soil samples to test the moisture level of the field prior to conducting each scenario, but this was inadvertently overlooked. Instead, a single set of soil moisture samples was collected for the South Field on October 7, 2004 (see Table 5-7: Soil Moisture Levels in Activity Area Soils).
The START conducted Baseball Scenario A and Baseball Scenario B according to the same scripted schedule used for the North Field. For Baseball Scenario C, however, the START conducted it entirely as a baseball infield practice scenario. The first 30 minutes of field maintenance activity (including the use of the steel drag mat) was replaced with infield practice play, so the scenario was still 2 hours in length.
South Field Baseball Scenario A. The START conducted activity-based outdoor air sampling during Baseball Scenario A at the South Field according to the same scripted schedule that was used for the North Field.
The outline of the field and the positions of the stationary air sample pumps operating during the South Field Baseball Scenario A are shown as SFBA-1FD, SFBA-2FD, SFBA-3FD, SFBA-4FD, SFBA-5FD, SFBA-1PG, SFBA-2PG, SFBA-3PG, SFBA-4PG, and SFBA-5PG on Figure 5-11 (Community Park South Field Activity-Based Outdoor Air Sampling Locations–Baseball Scenario A). Two composite samples collected during both baseball scenarios conducted on October 5 are shown as CC2-05-1CP and CC2-05-2CP. The position of the mobile meteorological station is shown as SFBA-MS. A summary of results for Baseball Scenario A samples is shown in Table 5-16 (Community Park South Field Baseball Scenario A Air Sample Summary Results).

South Field Baseball Scenario C (Without Field Maintenance). The START conducted activity-based outdoor air sampling during Baseball Scenario C at the South Field according to the same scripted schedule that was used for the North Field, except that the maintenance component of the scenario was eliminated. Instead, during the first 30 minutes the five other sampling team members (i.e., all but the sampling team member simulating a parent/adult spectator) conducted infield practice. For the remaining 90 minutes of the scenario, activities were conducted in the same manner as for the North Field.

Lower Soccer Field at the Community Park (Between North Field and South Field. The START collected soil samples to test the moisture level of the field just prior to conducting the scenario at the Lower Soccer Field (see Table 5-7: Soil Moisture Levels in Activity Area Soils).
The soccer scenario activity was conducted in three 40-minute sequential sessions on three separate rectangular areas where the grass was noted to be slightly barer than on other parts of the field.
The START conducted activity-based outdoor air sampling during the soccer scenario at the lower soccer field on October 7, 2004, according to the following scripted schedule:
- For the entire 2-hour scenario, one member of the sampling team simulated the activities of an adult/parent spectator sitting near the edge or walking around and occasionally within the area of play. This member of the sampling team would sometimes retrieve a ball kicked out of the area of play. The intake for the air collection filter cassette worn by this sampling team member was set at a height of about 5 feet.
- For the entire 2-hour scenario, five other members of the sampling team passed soccer balls back and forth to each other. They sometimes formed a small circle to practice passing; other times they dribbled the ball across the field with other sampling team members close by. They spent 40 minutes on each of three areas of the field. The intakes for the air collection filter cassettes worn by these sampling team members were set at a height of about 3 feet.
