MADISON (WKOW) -- A report from the Public Health Department of Madison & Dane County says the impact of fireworks-produced chemicals in a move of the Rhythm & Booms show from Warner Park to barges on Lake Monona will be brief, and pose no long-term concern.
The report was discussed Thursday by the Dane County Lakes and Watershed committee.
Concerns have been expressed about the impact on Warner Park's ecosystem from the staging of the show for twenty years at the site.
Report author Jeffrey Lafferty says the move to barges near Monona Terrace will help with the dispersion and dilution of chemical debris in the large body of water.
Lafferty's report points to Lake George, New York, where community fireworks displays are also detonated from barges, and states levels of perchlorate and other chemicals associated with fireworks dissipated in the water, and chemical concentrations were not found.
But the group, Midwest Environmental Justice Organization, points to a 2005 study of the impact of the Warner Parks Rhythm & Booms shows, and its inference decreased metal levels in the park's lagoon could mean some material migrated into other places, such as sediment.
Lafferty says clean-up of debris after the fireworks performance has been problematic at times at Warner Park on the city's north side, and says it's crucial new spectator areas be cleaned after the show. Lafferty says fireworks produced smoke should be taken into consideration by people susceptible as the result of health conditions such as asthma.
Lafferty says the fireworks show's move to off-shore from Monona Terrace will also ease traffic congestion and associated health effects from vehicle emissions.
