    Heavy metals in the garden

    This Washington State University Cooperative Extension factsheet explains the risks of heavy metals such as lead, cadmium, and arsenic in garden soils, with a focus on the greater Seattle-Tacoma region. It identifies locations most likely to have contamination, including sites near old painted buildings, heavily traveled roads, and areas affected by the former Tacoma smelter. The factsheet offers practical gardening tips to reduce exposure, such as growing fruiting crops, adding organic matter, liming soil, and washing produce thoroughly.

    Gardening on lead- and arsenic-contaminated soils

    This Washington State University Extension bulletin explains how lead and arsenic can contaminate home garden soils through historical sources such as lead-based paint, leaded gasoline, and arsenical pesticides, and why this poses health risks especially for children. It provides guidance on identifying contaminated soils through chemical testing and offers practical steps gardeners can take to reduce their exposure to these toxic elements.

As the source for federal transportation grants, the Puget Sound Regional Council was charged with developing a system to meet the growing need for commercial aviation. When the search for a second airport failed, they authorized the Port of Seattle to build the Third Runway, with a mandate to develop a noise abatement and mitigation program. In their effort to stop the Third Runway, the ACC argued over every detail of the Port's efforts--including property buyouts and sound insulation. The dispute was meant to be settled by a three member Expert Arbitration Panel. This is their final report. It finds 2-1, that the Port's program was insufficient in several respects. Despite that, funding for the Third Runway was approved by the PSRC, and the 'Port Package' program, proceeded largely unchanged. Expert Arbitration Panel's final decision finding that the Port of Seattle had not shown sufficient reduction in real on-the-ground noise impacts to satisfy noise reduction conditions required for approval of a third runway at Sea-Tac International Airport. The majority decision concluded the Port's noise abatement programs were insufficient despite being impressive in scope.
