DSSP doesn’t use the highly toxic, 50-year old perchlorate based solid rocket propellants that others use. The groundwater pollution legacy of perchlorate manufacturing and use is an ongoing 30-year legacy of wide spread health effects and ongoing lobbying by the polluters to suppress the US EPA regulatory actions. Perchlorates are endocrine inhibitors and have both acute exposure and long-term effects on thyroid function.
Just last year, Corona California spent $7M on an anion exchange water treatment plant specifically to remove perchlorates from their drinking water. Perchlorates are particularly dangerous to infants and fetuses reducing oxygen in the blood and causing low birth weights. So, perhaps you don’t care about communities you never heard of with perchlorate contaminated drinking water? Except, that perchlorate pollution from the Colorado River concentrates in the lettuce grown in areas of Arizona and California that use that water. Enjoy that next winter salad!
The Walt Disney Corporation rapidly replaced perchlorate based fireworks when contamination was detected in the lakes around Orlando.
The supply of perchlorates is highly controlled and is subject to supply/cost uncertainties of a single US manufacturer today.
Perchlorates are also really dangerous to make and the PEPCON manufacturing plant (near Las Vegas) accident created the largest domestic, non-nuclear explosion in recorded history. Watch the massive shock wave that sweeps across the desert! Expanding the use of perchlorates is dangerous to people and the environment.
