Re New Bedford Harbor Dredge ndash Phase II Water Quality Monitoring Report

Date July 26 2005

Attached is the water quality monitoring results from the dredging operations for the New Bedford Harbor Dredge ndash Phase II from July 6 2005 through July 22 2005 Also included are the monitoring results from EPA Operable Unit 3 (OU 3) cap placement from July 6 2005 through July 22 2005 Water quality monitoring was performed in accordance with the Water Quality Monitoring Plan dated 010505 and Figure 6 (Water Quality Monitoring Decision Sequence) and Figure 7 (Analytical Protocol Decision Sequence) dated March 2004 provided to Apex by the Environmental Protection Agency (EPA) Included in this report are spreadsheets tabulating the turbidity results from each day and a map of the sampling locations

Following the guidelines of the WQMP and EPA documents monitoring locations for water turbidity recorded an average turbidity over various water depths up and down-current from the dredge or material placement operations depending on tide The values recorded as the Reference Site Turbidity were taken from up-current monitoring locations or from monitoring events which occurred before dredge or material placement operations began The Reference Turbidity Value was then compared to down-current turbidity values measured at regular time intervals after operations had begun

Water Quality Monitoring Results Summary (Dredging)

For dredge operations an exceedance of the project turbidity standard occurs when the average turbidity down-current exceeds the Reference Turbidity Value plus the permissible turbidity increase as outlined in Section 33 of the WQMP For a reference value less than 10 NTUs the down-current permissible turbidity increase is plus 20 NTUs The permissible turbidity increases for operations with or without silt curtains are the same only the distance from the dredge to monitoring locations changes

(Boston MA Office (617) 728 ndash 0070)

Dredging events were monitored on six days 7605 7705 71105 71205 71505 and 72205 during dredging operations Water quality monitors selected various sample locations around the dredging area to collect data There were no turbidity exceedances to report during the dredging events

Water Quality Monitoring Results Summary (Cap Placement)

Water quality monitoring during cap placement in the OU 3 area followed the guidelines set forth in the documents provided by the EPA Material placement events were monitored on six days 7605 7705 7805 71205 71405 and 72205 Water quality monitors selected various sample locations around the placement area to the down-current flow of water from the cap placement operations There were no turbidity exceedances to report during the material placement events

The preliminary results from the second phase of water quality monitoring show that dredging and cap placement operations have stayed within the permissible turbidity levels set forth in the Water Quality Monitoring Plan and the EPA documents provided on the dates which monitoring occurred

Dredging events were monitored on six days 7605 7705 71105 71205 71505 and 72205 during dredging operations Water quality monitors selected various sample locations around the dredging area to collect data There were no turbidity exceedances to report during the dredging events

Water Quality Monitoring Results Summary (Cap Placement)

Water quality monitoring during cap placement in the OU 3 area followed the guidelines set forth in the documents provided by the EPA Material placement events were monitored on six days 7605 7705 7805 71205 71405 and 72205 Water quality monitors selected various sample locations around the placement area to the down-current flow of water from the cap placement operations There were no turbidity exceedances to report during the material placement events

The preliminary results from the second phase of water quality monitoring show that dredging and cap placement operations have stayed within the permissible turbidity levels set forth in the Water Quality Monitoring Plan and the EPA documents provided on the dates which monitoring occurred
