Westlands Water investigation sought
Tainted drainage water is moving, activists say.

River's flow to ocean strong sign for San Joaquin rebirth
On the Valley's west side near Los Banos, something strange is happening
this summer in the San Joaquin River -- water.
The river has continued to flow to the Pacific Ocean throughout the first
summer after an ambitious restoration effort began, sending a powerful
signal about the project's potential for success.
This end of the river has been dry in summer since Friant Dam was finished
in the late 1940s.
Kings River park puts danger within floaters' reach
Floating the Kings River on an inflatable raft or inner tube with nothing
but a swimsuit, sunglasses and cooler of beer is a summertime tradition.
But head upriver a few miles, closer to the foothills, and the Lower Kings
takes on a different character. The current quickens with the gain in
elevation, creating sections of rapids and navigational hazards.
Floaters unprepared for this kind of trip should steer clear of a new launch
facility just above the Highway 180 bridge, authorities and experienced
boaters say. They'll get more than the lazy, carefree ride they bargained
Calling for a state investigation, water activists say tainted irrigation
drainage from Westlands Water District is moving undetected into the San
The nonprofit California Water Impact Network says underground drainage in
Westlands is migrating slowly downhill to neighboring farmland, where
subsurface drainage is captured and sent to the river.
"We'd like to know how much Westlands contributes," said Tom Stokely of the
water network. "We think it might be significant."
Westlands officials say the activists are wrong, adding that the district
has a history of trapped underground drainage that does not move. Officials
said they welcome the scrutiny.
The activists' request for the state study came Thursday, just days after
the state approved a nine-year extension on a drainage cleanup program for
the neighboring farmland that sends some drainage into the river.
Farmers on 97,000 acres downslope from Westlands have been dramatically
reducing drainage contaminants for many years in the Grassland Bypass
Project. The activist network, based in Santa Barbara, opposed the extension
and is considering legal action against it.
Activists say the farm drainage in the Grassland project makes the San
Joaquin exceed the standard for a natural element called selenium, which is
toxic to wildlife in high doses.
The contamination spreads downstream to the Sacramento-San Joaquin Delta,
where dwindling fish species suffer, activists say.
Westlands was painted as an environmental villain in the 1980s when
biologists discovered high concentrations of selenium had killed and maimed
wildlife at evaporation ponds.
The selenium-laced water had been drained from beneath Westlands fields. The
underground geology in parts of Westlands traps the bad water, which must be
captured in perforated pipes and removed or it will poison the land.
After the wildlife disaster in the 1980s, the ponds were closed and
thousands of acres were taken out of production. But a lot of drainage
remains trapped. For years, the district has been involved in legal action
against the federal government to dispose of the bad water.
Even though Westland's fields are upslope from the Grasslands Bypass
Project, the water could only migrate very slowly over centuries, said
Westlands general manager Tom Birmingham.
"The state has studied this type of claim against the district many times
before and has rejected them," Birmingham said. "We think it's a good idea
to put this ridiculous assertion to rest."
