They utilize a precise technology to remove contamination from targeted areas. A cutting head dislodges the contaminated sediment which is immediately suctioned into a flexible pipe. It is then pumped onto a covered floating barge or directly to an on-land area for dewatering. Their job is to contain any loose sediment that may be contaminated with PCS, heavy metals or other toxic materials within the work zone. In addition, setting up multiple water testing sites in the vicinity of the dredging area immediately detects any problems.<\/p>\n<p>The job specific requirements of environmental dredging precludes the use of off the shelf standard floating turbidity barriers and silt curtains. There are numerous details and site-specific factors to consider.<\/p>\n<ul>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">What is the material and contaminant being dredged from the waterway?<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Is it soluble,viscous, or heavy and will sink in the water column?<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Will the contaminant be reactive to the standard PVC silt curtain material?<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Should another containment material be used to make the turbidity or containment curtains?<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Should a multi-layer turbidity curtain containment system be used?<\/span><\/li>\n<\/ul>\n[\/vc_column_text][\/vc_column][vc_column width=&#8221;1\/6&#8243;][\/vc_column][\/vc_row][vc_row][vc_column][mk_padding_divider size=&#8221;50&#8243;][\/vc_column][\/vc_row][vc_row][vc_column width=&#8221;5\/6&#8243;][vc_column_text css=&#8221;.vc_custom_1523042859121{margin-bottom: 0px !important;}&#8221;]\n<h3><b>Wetlands Remediation \/ Restoration<\/b><\/h3>\n[\/vc_column_text][mk_divider style=&#8221;thin_solid&#8221; thin_single_color=&#8221;#e5731b&#8221; thickness=&#8221;2&#8243; margin_top=&#8221;0&#8243; margin_bottom=&#8221;0&#8243;][vc_column_text css=&#8221;.vc_custom_1548449683559{margin-bottom: 0px !important;padding-top: 25px !important;}&#8221;]Hydraulic or mechanical dredges can be used in areas where flotation is possible. However, some jobs require temporary water diversion to access shallow areas from the embankment with land-based equipment. Deploying staked turbidity barriers around the work zone is a solution when using a floating barrier is not practical. Floating barriers tend to lay over in the mud, not coming back up when the tide comes in.[\/vc_column_text][\/vc_column][vc_column width=&#8221;1\/6&#8243;][\/vc_column][\/vc_row][vc_row][vc_column][mk_padding_divider size=&#8221;50&#8243;][\/vc_column][\/vc_row][vc_row][vc_column width=&#8221;5\/6&#8243;][vc_column_text css=&#8221;.vc_custom_1523043315284{margin-bottom: 0px !important;}&#8221;]\n<h3><b>In-Situ Sediment Capping<\/b><\/h3>\n[\/vc_column_text][mk_divider style=&#8221;thin_solid&#8221; thin_single_color=&#8221;#e5731b&#8221; thickness=&#8221;2&#8243; margin_top=&#8221;0&#8243; margin_bottom=&#8221;0&#8243;][vc_column_text css=&#8221;.vc_custom_1548191259102{margin-bottom: 0px !important;padding-top: 25px !important;}&#8221;]In-situ sediment capping eliminates excavation and disposal of contaminated material off-site.
