From http://www.natureswayresources.com/ :
Research at Bucknell University has found that the leachate from ground tires can kill entire aquatic communities of algae, zooplankton, snails and fish. Even at low concentrations it can cause reproductive problems and precancerous lesions. Also, marine life from seaweeds to plankton is negatively affected.The toxic nature of the leachate from tire rubber is due at least in part to the chemicals usedin producing tires (cadmium, chromium, aluminum, copper, iron, manganese, molybdenum, selenium, sulfur, and zinc). Of these minerals, rubber tires may contain extremely high levels of zinc even up to 2% of the tire mass. Many plant species have been shown to accumulate zinc in their tissues to the point of death. USDA researchers who have studied the effects of metals in sewage sludge, biosolids and compost, have found that ground rubber should not be used on any agricultural or garden soil, potting media, or compost. Yes- some companies use tire chips and crumb rubber as a bulking agent for compost and we wonder why the compost does not work and is toxic to plants! Other rubber leachates have been found to cause problems from skin and eye irritation to major organ damage and even death. Long term exposure can lead to carcinogenesis and mutagenesis. For example, 2-mercaptobenzothiazole used in vulcanizing rubber is highly persistent in the environment and harmful to aquatic life. Ground rubber also contains a class of chemicals called Polyaromatic hydrocarbons (PAHs) that many studies have found extremely toxic to humans and the environment. Research has also found that the toxicity of leachate from the
rubber tire mulch increases over time as the rubber breaks down.

This is what we want to spend $12K on to dump right next to the Winnequah Lagoon? I would really like to see the Blue Park covered with adequate fall zone protection with whatever depth of sand is necessary. Not only is it cheaper, cleaner, less smelly and a whole lot more fun to play in, it won't leach into our ground water and kill off our aquatic wildlife. Call me an old fogey.
Also on tap for Park and Rec. Board: From Director Jake Anderson "Mayor Robb Kahl has requested that the existing soccer/football field at Ahuska Park be named Tom Metcalfe Field after former Mayor Tom Metcalfe. Kahl states that Tom Metcalfe was the Mayor of Monona at the time of the park being built and was instrumental in turning the site into a usable park. This would be the first step in any naming process. There would be a 30 day public input notice before the Park and Recreation Board could make a recommendation one way or another."
The Monona Grove Board of Education will meet this Wednesday evening at 7pm in the District Office Board Room in Nichols School. Unfinished business includes the discussion and possible approval of 2010-2011 Teacher Final Notices of Layoff and the possible approval of the location of the MG Alternative High School and general discussion of the Nichols Building. The two items of new business are the discussion and possible approval of district computer bids and the student fee schedule.
The Monona Family Attraction and Retention Committee will meet this Thursday in the Monona City Hall Conference Room at 6:30pm. Alderman Doud Wood will become our committee's new co-chair with Alderman Scott Munson serving as the new chairman. We plan on having a review of the Family Attraction Committee's charge and mission and a brainstorming session on future committee projects. We will also begin discussing this year's Fall Family Festival and hope to choose a date in the early fall. As always, we would welcome any volunteers to assist in the festival planning. The 2009 Festival was wonderful; we hope this year will bring another success!
