DREDGING AND RECLAMATION PROGRAMME IN KINGSTON HARBOUR

The R1 bund preparation continued during the period covered by this report. First sector completed, material dredged from PB dredge site was still being pumped into the completed section of R1 from the Leonardo Da Vinci. Significant plume noted from the outlet weir in R1. Screen around outlet appears to be holding.(See Photographs)

The Christoforo Colombo dredged in the H1 and H2 areas at the following times:

16/01/2002 07:50 – 21/01/2002 11:35

21/01/2002 20:10 – 22/01/2002 02:05

22/01/2002 23.10 – 25/01/2002 15:30

25/01/2002 23:30 – 31/01/2002 13:55

05/02/2002 17:15 - 10/02/2002 08:30

The Christoforo was in the channel again between Wed. 20^th and Friday 22^nd February, bur the exact times were not available in time to be included in this report.

Monitoring flights were carried out on February 11^th and February 19^th.

A water quality monitoring exercise was carried out on February 18^th

The flight of February 11^th suggested that the screen at R3 was not very effective at the time of the flight, however the “plume” noted in the attached photograph was in fact material on or near to the sea floor as the depth in the occluded area was generally less than 0.6 m. There is some drift of the plume toward the SW which will be further monitored. Water quality results for samples collected in this area on February 18^th are discussed later in this report. Laboratory analysis results for the set of samples collected in December is now available, and the data is reviewed in this report.

WATER QUALITY MONITORING

1. December 13, 2001

This is a follow up of data presented in Monitoring report #3 dated 3^rd January 2002

Methodology:

Monitoring of activities by sea. Water samples collected and field measurements made. Photographs taken.

Results:

Results of laboratory analysis are represented in Figure 1 and Table 1. TSS data were discussed in Report No. 3. [4]

4B				2	0	111.0	520.9

Biological Oxygen Demand (BOD), was <2 at all stations. COD was determined to be in the range 351 – 721 for all samples. The highest values were determined for the sample from the dredge site 3T and 3B, where COD was 677 and 721 respectively. Turbidity was determined to be in the range 0 – 48 NTU for all samples. The highest value for th s parameter (128 NTU) was determined for station 3 in the dredge plume where TSS was determined to be 93.6 mg/l. Other high values were determined for 3T, where turbidity was 48 NTU compared to a TSS of 242 mg/l, and 3B where turbidity was 22 NTU, while TSS was 116 mg/l. At 1T and 1B turbidity was 3 NTU but TSS was 78 and 115 respectively. At 4T (1NTU), and 4B (0 NTU), TSS was 436 and 111 respectively.

2. January 16, 2002

This follows up on Monitoring report #4 dated 24^th January 2001 and presents the results of laboratory analysis
