5.0 SUMMARY AND RECOMMENDATIONS 



• Routine monitoring at MQR has indicated a pattern of anomalous 

 recolonization relative to other CLIS capped mounds. Historically, MQR has 

 exhibited slow recolonization rates relative to other capped mounds at CLIS. 



• MQR provides an excellent test case for the dredged material management 

 protocols as described in the Tiered Monitoring Program created for the NED. 

 It is the first mound to trigger higher tiers of monitoring and testing, under the 

 tiered monitoring framework. Following these tiered protocols, several 

 monitoring surveys, including REMOTS® work and sediment sampling, have 

 been conducted at MQR. 



• A reconnaissance REMOTS® and bioassay survey in 1991 showed a substantial 

 regression of benthic environmental parameters since the previous survey in 

 1987, which suggested a small-scale physical disturbance. 



• Results from the 1992 REMOTS® survey at CLIS showed a clear improvement 

 of the habitat quality at MQR since the 1991 survey, although still anomalous 

 relative to the CLIS reference area. 



• The persistence of slow recolonization since the formation of MQR, together 

 with sediment chemical results presented in an earlier report, indicate that 

 MQR should be further capped, and monitoring should continue.
