GL: Lectrasan vs. Purasan question

[Skipper Bob]

Steve,

You said "I am fully aware that Canada doesn't approve of either. "

Are you also aware that many places in the United States and on the 
Great Circle Loop particularly do not approve of either. Listed below is 
the information as presented in my book The Great Circle Route.

Extract from The Great Circle Route

Finally, the matter of type I (like Lectra/San.) treatment systems. The 
Environmental Protection Agency has designated several areas on the 
Great Circle Route as No-Discharge Zones. In these areas you may NOT 
use the type I treatment system. (This does not impact gray water 
discharge) These No-Discharge Zones include, but are not limited to, 
Destin Harbor FL, all of the Florida Keys, all waters in Michigan, the 
Manasquan, Shark, and Navesink Rivers in New Jersey, and the Hudson 
River. For more information, if you have access to the Internet, check 
the web site www.epa.gov/owow/oceans/vessel_sewage/

No-Discharge Zones.
