|I have, over
the years that my drinking water information site has been active, been asked
to provide some personal details by visitors wishing to know how to cite the
information in research papers (or simply wanting to know what my credentials
are for putting together a drinking water information site):
Randy Johnson, MS,
I have lived most of my life in Littleton, Colorado, a southern suburb
of Denver, graduating from Littleton High School, and earning a BA degree in
biology with a minor in chemistry from the University of Colorado in Boulder,
CO. I completed a Masters of Science in molecular genetics from Northern Arizona
University in Flagstaff, AZ. I have taught biology and physical science at
the high school and college level. I currently am employed at the Denver VA
Medical Center and provide data analysis, database management, computer support,
and quality management reporting for the Cardiac Surgery Team.
I have always been
interested in science, and in understanding how things work, whether it is a
radio or the universe. I was very annoyed
a number of years ago when trying to locate useful information on the internet
about drinking water and water treatment options. Most of the
information I found was quite exaggerated, very biased, or just plain
wrong. The number of sites containing accurate information about
drinking water is far greater today than when I started the site (probably in
97), but there is still a tremendous amount of exaggerated, biased, and just plain
wrong information on the web.
With a solid background
in science, research training (both experimental and library), and a strong interest
in education and statistics, I decided to distill everything I knew or could
find out about drinking water and build my own reference site. I try to
find several reliable sources for everything I publish and then make certain
it is consistent with the knowledge I already have. As I discover new
information I try to post it.
I hope you find the
information collected on my web sites useful.
personal information and interests below:
engaged in one of my favorite activities these days - on the risers singing with
the men's a cappella chorus I am privileged to be a member of, The Sound
of the Rockies out of Denver, Colorado. Sound of the Rockies is
a competitive member of the Barbershop
Harmony Society, and this picture
was taken on the International Stage in Montreal, Quebec,
July 5, 2003
where the chorus placed 7th in a field of 20
choruses from the United States, Canada, and England. This last
summer, 2006 the chorus placed 6th at International Competition in Indianapolis,
IN. Excitement is building for the 2007 competition which will be held
here in Denver in early July. Sound of the Rockies is planning to medal
this time around.
over 800 chapters of the Barbershop Harmony Society
in the United States and Canada. In many cities and towns these chapters,
which often consist of an a cappella chorus and several quartets, provide
top-quality, family entertainment opportunities in their
communities. I would strongly encourage anyone who loves music to
check the BHS
listing of chapters, determine if there is a nearby chorus and/or quartet,
contact them to find out when/where they will be performing next, and plan to
attend a concert. On a whim, my wife and I attended a SoR concert in
November of 2001, and I was so amazed by the sound and energy coming from the
stage, that I determined to become a part of the group. You can read this
story at YourHub.com
(you may need to register).

Portland, Oregon, July 2002, where the chorus placed 8th.

singing and work - and updating websites, I keep busy with a variety of activities and interests which
and cosmology - I am fascinated by the universe we inhabit, and
periodically, on dark nights (which are sadly becoming rarer as light
pollution increases), I drag my telescope out to look at the planets and
an assortment of deep space objects. I can only marvel at the images
that the Hubble
Space Telescope has brought to the world.
One of the most
amazing events I have witnessed was watching the 2001 Leonid
meteor storm for several hours after midnight with my family as
"shooting stars" rained down out of a dark, clear sky at an incredible
rate! Took a lot of neat pictures - and later discovered I had forgotten to load my camera.
and amateur rock and mineral collecting - Living in Colorado provides
some fun locations for mineral and fossil collecting with my wife and
son. We spent one afternoon, for example, collecting calcite crystals
and chipping plain opal out of a hill near Grand Junction.
- Although the recent drought has put a crimp in this activity, I enjoy
growing, harvesting, cooking and eating the produce of my garden.
Vintner - An
attempt ten years ago to brew wine from concord grapes picked in a
neighbor's yard effectively killed any desire to repeat the experience - -
- until recently. My wife and I enjoy a good bottle of wine and we
just (4/07) decided to try several of the varietal wine kits on the market
- started with a Cabernet Sauvignon (which will take several years to
mature) and will soon start brewing a Chardonnay (because we can't wait
several years to begin drinking the fruits of our labor).
and graphics design - I put this water site together, and I help with
creating and managing the Sound of the Rockies'
web site and developed a series of web pages to promote my Dad's new
Thread of Gold, a historical- fiction adventure novel
about the search for a lost gold bonanza in the the Colorado Rockies,
which is scheduled to be published in summer 2005..
- My wife and I enjoy, when time allows, digging into the spice rack and
creating culinary masterpieces. We just processed 50 pounds of
chokecherries we collected along the nearby Highline Canal (Aug 03) for
making jelly, and perhaps some wine.
- It's a fun challenge to capture the nuances of a moment in time and
place on a piece of film - or more recently digitally encoded - and try to
create a beautiful image out of light, shadow, form, and color.
singing and guitar playing - I have been singing and playing the
guitar since high school. My old guitar has been a good companion
over the years at home, off at school, and on camping trips.
and collecting antique books & magazines - Nothing beats
curling up after a long day (or before a long day, for that matter) with a
good mystery or Sci-Fi book.
Yours in Harmony
