SUMMARY OF IMPACTS...

THERE CONTINUE TO BE LOCAL...STATE AND NATIONAL NEWS STORIES ABOUT
DRY WELLS IN THE SAN JOAQUIN VALLEY...EXCESSIVE GROUNDWATER
DRAWDOWN AND THEFTS OF WATER FROM MUNICIPAL WATER SYSTEMS. THERE
CONTINUES TO BE SIGNIFICANT MEDIA COVERAGE ON THE ON-GOING DROUGHT
CONDITIONS. THESE REPORTS INCLUDE DISCUSSION OF FARMERS FORGOING
PLANTING OF SOME CROPS...REDUCTION IN AIR QUALITY DUE TO PERSISTENT
STAGNANT AIR...AND LOSS OR REDUCTION OF GROUND WATER.

THE HANFORD SENTINEL ON JANUARY 27TH CARRIED A FRONT PAGE STORY ON
THE LEECHING OF URANIUM INTO WELLS IN THE SAN JOAQUIN VALLEY DUE TO
HEAVY PUMPING OF GROUND WATER. THE SENTINEL /JANUARY 30TH/ AND
FRESNO BEE /JANUARY 30TH AND FEBRUARY 1ST/ CARRIED STORIES ON THE
SNOW SURVEY OF JANUARY 29TH...WHICH FOUND THE SNOW WATER EQUIVALENT
WAS WELL BELOW NORMAL AFTER AN UNSEASONABLY DRY JANUARY. THE HANFORD
SENTINEL ON FEBRUARY 14TH CARRIED A STORY ABOUT THE IMPACT OF THE
DROUGHT ON SKI RESORTS IN THE SOUTHERN SIERRA NEVADA.

THE OVERDRAFTING OF GROUNDWATER HAS CAUSED SUBSIDENCE IN PARTS OF
THE SAN JOAQUIN VALLEY...ESPECIALLY IN MADERA AND TULARE COUNTIES.
THIS SUBSIDENCE LIKELY HAS CAUSED SOME REDUCTION IN THE SPACING
BETWEEN SOIL PARTICLES DUE TO COMPACTION. THIS COULD IMPACT THE
AVAILABLE SPACE AVAILABLE FOR GROUNDWATER STORAGE...AND SOME
AQUIFERS MAY NOT RECHARGE TO PRE-DROUGHT CAPACITIES.
