infiltration trench An infiltration trench (a.k.a. infiltration galley) is a rock-filled trench with no outlet that receives stormwater runoff. Stormwater runoff passes through some combination of pretreatment measures, such as a swale and detention basin, and into the trench. There, runoff is stored in the void space between the stones and infiltrates through the bottom and into the soil matrix. The primary pollutant removal mechanism of this practice is filtering through the soil. best management practice,pollutant discharge,elimination,green,development

permeable pavers Permeable pavers are brick-like materials that are manufactured in a variety of shapes. Pavers fit together like tiles and are set with small gaps between them, creating grooves for water to infiltrate the soil beneath. Permeable pavers reduce stormwater runoff volume and flow rate, and increase groundwater infiltration and recharge. best management practice,stormwater management,pollutant discharge,elimination,green,landscape

Oil Spill Containment Positioned by multiple vessels, an attempt to contain an oil spill is made using temporary floating booms. Booms are used to reduce the possibility of polluting shorelines and other resources, and to help make recovery easier. Booms help to concentrate oil in thicker surface layers so that skimmers, vacuums, or other collection methods can be used more effectively. symbol,vector,illustration,fossil fuel,extraction,exploration,offshore,drilling,BP,Deepwater Horizon,spill,clean up,response,safety,environmental degradation

Cages protect seabeach amaranth (Amaranthus pumilus) from grazing A sensitive species, seabeach amaranth is aided at Assateague Island National Seashore by a management program that protects a portion of the annual population from being eaten and trampled by horses and deer so they can mature and produce seeds. Conservation efforts have helped the plant population increase to nearly 2,200 individuals in 2007. plant,native,endangered,Maryland,beach,overwash

Homeowner is allowed to fill in wetlands On a property that was grandfathered to build on a tiny waterfront lot, the owner was allowed by the local zoning department to fill in a low wetland where his well (white pipe) and dock electric service (right center of photo) were located. As this photo documents, this low area was frequently flooded. sea level rise,flooding,critical area,development,Talbot County,Maryland

Oyster racks At Drakes Bay Oyster Company near Point Reyes, CA, oysters grow either as singles or in clusters. The singles are grown as individuals from the larval stage. The single oysters are produced in the indoor hatchery located on-farm, and are then moved to the growing area in mesh bags to resist predation from bat rays. Clusters are created by setting many larvae on shells saved from the shucking and packing operation. These "mother" shells containing the oyster spat (baby oysters) are then strung together on wires and suspended in Drakes Estero. aquaculture,shellfish,west coast,California
