Celebrating Summer with Service

August 3, 2012.

Aspect again celebrated summer by combining our annual picnic/bbq with civic service. This year we sent volunteer crews out to two projects. Our beach crew worked with Puget Sound Restoration Fund sorting oysters growing on the organization’s Bainbridge Island community shellfish farm.

Our trail crew built a boardwalk at Heritage Park in Kingston to finish trail work we had first undertaken at our 2010 summer event.

With dogged perseverance under the midday sun, Aspect volunteers had the shellfish sorted and back in their grow bags well before the high tide came in to cover the farm area.

Meanwhile, the trail crew overcame creative differences in design to construct 50’ feet of 6-foot wide boardwalk over a streambed to replace a muddy section of the trail.

After successful completion of the projects, both groups convened in a backyard overlooking the Sound for a summer bbq of lobster, tri-tip, and (of course) fresh oysters.

One Site. Four Sources. One System.

​The groundwater beneath an eight-acre shopping center exhibited chlorinated solvent impacts from four different source areas of varying ages.

To sort out the complexities of multiple sources with multiple responsible parties, Aspect hydrogeologists distinguished the relative solvent contribution from each historical source and developed a site conceptual model that was used to reach an equitable cost-sharing agreement. At the same time, our remediation engineers pilot tested an in situ chemical oxidation system for groundwater treatment without disruption to the active retail facility.

The final remediation system treats all source areas through one air sparge and soil vapor extraction (AS/SVE) system consisting of 16 soil-vapor extraction wells and 47 air-sparging wells spread over an acre of the property.
