Report Dated 07/21/98
As of July , there are 2411 traps in service: 2016 Jacksons, 283 panels, and 112 McPhails.
Environmental Monitoring: The following results are from samples collected on 6/17 and 6/18, prior to and following the second aerial bait treatment:
BDL = Below Detectable Level
| 6/17 | 6/18 | |
| Terra Ciera Bay | BDL | 0.1 - 0.3 ppb |
| Champlain Bay | BDL | BDL |
| Clambar Bay | BDL | BDL |
| Emerson Bay | BDL | BDL |
| Snead Island Cutoff | BDL | BDL |
| McLewis Bayou | BDL | 0.41 ppb |
| Warners Bayou | BDL | 2.0 ppb |
| Palma Sola Bay | BDL | BDL |
| Palma Sola Creek -S | BDL | 3.8 ppb |
| Palma Sola Creek - W | BDL | 1.3 ppb |
| Cedar Hammock | BDL | 22 ppb |
All samples were BDL for malaoxon.
The minimum detection limit (MDL) and practical limit of quantitation (PQL) remain unchanged at 0.1 and 0.3 ppb respectively.
Drift data for this sampling event were reported in the 6/25 update. All were BDL for malathion and malaoxon.
The following results are from samples collected on 6/24 and 6/26, prior to and following the third and final aerial bait treatment:
| malathion | malaoxon | |||
| 6/24 | 6/26 | 6/24 | 6/26 | |
| Terra Ciera Bay | BDL | 0.99 ppb | BDL | BDL |
| Champlain Bay | BDL | 0.32 ppb | BDL | BDL |
| Clambar Bay | BDL | 0.1 - 0.3 ppb | BDL | BDL |
| Emerson Bay | BDL | BDL | BDL | BDL |
| Snead Island Cutoff | BDL | 0.1 - 0.3 ppb | BDL | BDL |
| McLewis Bayou | BDL | 0.92 ppb | 0.1-0.3 ppb | BDL |
| Warners Bayou | BDL | 1.4 ppb | BDL | BDL |
| Palma Sola Bay | BDL | BDL | BDL | BDL |
| Palma Sola Creek -S | 3.4 ppb | 2.9 ppb | 4.0 ppb | 0.4 ppb |
| Palma Sola Creek - W | 2.2 ppb | 7.3 ppb | 3.5 ppb | 0.1 - 0.3 ppb |
| Cedar Hammock | 21 ppb | 2.7 ppb | 9.0 ppb | 0.22 ppb |
NOTE: there are some higher concentrations noted in some of these samples - I have not had an opportunity to check environmental conditions (rainfall events, etc) that may be associated these findings. I am aware of at least one signficant rainfall event - but don't have data at this point.
Drift monitoring for the third and final aerial bait treatment:
McLewis Bayou: all samples BDL for malathion and malaoxon. Drift cards were placed at water's edge, 50m, 100 m, 150 m, and 180 meters from waters edge.
Palma Sola Bay: BDL at 50 m and 100 meters from waters edge; positive (trace) at 200m, 250m, and 300 meters from waters edge; positive at 350 meters from waters edge.
Health monitoring: As of July 6, the Department of Health (DOH) has received a total of 196 calls with health related complaints. Of these Manatee CHD received 182; Tampa Poison Information Center received 6, and DOH/Tallahassee received 8 calls.
179 of the calls were related to the three aerial bait treatments. The remaining 17 calls were related to ground bait treatments.
DOH/Tallahassee is continuing to follow up on these calls, and is reviewing its preliminary case classification. DOH has identified respiratory and dermatologic responses as associated with the malathion-bait treatment, but without additional follow up, cannot determine if the response is due to malathion, the bait, or neither.
There are 5204 traps deployed: 3929 Jackson, 1066 yellow panels, 192 McPhails, and 17 IPTs. Please see the attached summary of USDA data. In addition to the water data presented there, USDA has also sent data on drift cards and vegetation at protected human sites, and data from three swimming pools. Please contact me if you need a copy. I believe we have previously reported out the DACS water/drift data; however, if I'm in error - please let me know - I'll send that out as well.
This concludes my updates on these two programs, unless I receive new data, or the status should change in either of the programs.
