Sorry for the bad subject line on the last email.  Mapping, mapping,
mapping.

For those of you who have wished for an easy way to map graywater projects
(or other projects that your city, agency, company or organization has
going), here is a tool for you:

www.habitatmap.org <http://www.habitatmap.org>

I like that you can mix and match with info from other maps.  I¹ve got one
going for water reuse demonstration projects (almost no info yet).

The two strategies we recommend to deal with salt are:

1) Minimize it's application (biocompatible cleaners, etc.0
2) Deep flushing seasonally with RAIN...the best salt-flushing product on
planet earth!
