Itís the Water
Water Resources and Water Quality
By Larry McCollum
of the Contra Costa Water District

We ride our bikes along the canal system on weekends.  We walk along these same paths for exercise at lunch. We throw away the water quality reports that arrive annually in our mailboxes as just another piece of junk mail. We take our water for granted. But water and water quality can be critical to our hobby of growing orchids. 

After reading the latest annual report I decided that it might be nice to find out where our water comes from.  Maybe we should know how to read the annual report.  And know the difference between hardness and calcium carbonate concentration, know what total dissolved solids means, as well as eletroconductivity testing of water.   

What?  This has gone over your head? You feel awash and drowning in terms you donít understand?  Have no fear!  You really donít need to know any of these terms in order to grow orchids.  But some folks say that in order to grow them well is another story.  Believe me, some hobbyists really get into the caliber and quality of their water!

If anyone can knowledgeably discuss Contra Costaís water its Larry McCollum, supervising water scientist at the CCWD.  The Contra Costa Water district has a long history of public service and community outreach.  We are able to hold our meetings in the CCWD Board room because the CCCWD is committed to public service. The Contra Costa Water District delivers safe, clean water to 450,000 people in central and eastern Contra Costa County in Northern California. 

Formed in 1936 to provide water for irrigation and industry, CCWD is now one of the largest urban water districts in California and a leader in drinking-water treatment technology and source water protection. As a public water agency, the Contra Costa Water District (CCWD) has over the years made a concerted effort to share information about its public services with many and varied audiences.

 Raffle Table will be provided by Gold Country Orchids, Lincoln, Ca.
