Biosolids Stench Dissipates From Glen Ellyn After Wastewater Plant Takes Action
Glen Ellyn, IL (10/2/17) -- In our last Newsclips we heard about the initial discovery of odors from digesters in Glen Ellyn being in an “upset condition” in the article Overwhelming Odor in Glen Ellyn: Wastewater Authority Presents Game Plan. Since then, the facility took action and recently a third-party testing facility found that "none of the organic compounds detected in the area around the wastewater treatment plant exceeded the acceptable levels according to the National Institute of Occupational Health and Safety Standards."
Study: Rain and Snow Can Transport Chemicals to Minnesota’s Lakes, Rivers

Soil Amendments for Healthier Spinach
Salinas Valley, CA (10/4/17) -- Soils in Salinas, California are naturally rich in cadmium and as a result, spinach grown in the area can sometimes contain levels of cadmium beyond the amount determined safe. To address high levels of cadmium in otherwise fertile soils, researchers from the Sustainable Mineral Institute in Brisbane, Australia are testing zinc and manganese salts, limestone and biosolids compost as soil amendments. Research found that a combination of compost, zinc and limestone brought the levels of cadmium found in spinach down to nontoxic levels. They hope to extend the study to determine the ideal combination of amendments and to study vegetables besides spinach.

Making a Stink
Spokane, WA (9/21/17) - This is another story coming from Spokane about the proposed biosolids permit for land at Rosman Farms. Community members formed the group, Protect Mill Canyon Watershed, that opposes the permit and is calling for the Department of Ecology to “halt all biosolids permits in the state until further research is completed”. Their effort is supported by the local Sierra Club, the Columbia Institute for Water Policy and other environmental groups and nonprofits. For more information, you can check out the article included in the last Newsclips “Mill Canyon Farm Applies to use Fertilizer Derived from Municipal Sewage” or another article we found this week “Lincoln County Residents Fight Biosolids on Nearby Farm”
