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

Suggest everyone read the actual bill language that passed.  The mercury
language was changed by Rep. Kirk to an EPA review of mercury monitoring
provisions.

Everyone ought to also remember that the bill was discussed in the House
under a modified open rule, which meant that any amendment could be
considered as long as it was given to the Congressional Record 24 hours
in advance.  For the record, there were also amendments dealing with
national security, pharmaceuticals, and oil/gas, but these were dropped.
In other words, the amendments did not have to be related to pathogen
monitoring and reporting at beaches.

As soon as I saw the mercury language in the BEACH Act amendment, I was
also confused.

The best chemical predictor of elevated bacteria levels I've found is
salinity, for which low values simply indicate high levels of freshwater
influence at beaches near a freshwater outlet (river, storm drain, or
otherwise). But this is certainly site-specific; some beaches tend to
exceed criteria during high tides (high salinities) due to flushing of
terrestrial sources.

But mercury? What gives?

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?
