Re: BEACHNET==> Mercury as a Pathogen Indicator.

Agreed. The closest linkage is nitrogen from emissions, but nothing on pathogens.

As for other chemical markers like coprostanol, caffeine or optical brighteners, they are used for source tracking only.

Chemicals have never been able to serve as a pathogen indicator.   I know of no data which would correlate mercury to other microbial pollutants of concern.  I do not even think that most of the sources are correlated (industrial and atmospheric).
Do you know anything more about it?

        Representative Mark Kirk offered an amendment to the Beach Protection Act of 2008 “to treat Mercury as a Pathogen Indicator”.  I’m looking for what the main point of this amendment is.  Is it that mercury should be consider a contaminant or an indicator of something else?
