WATER INNOVATION
that many irrigated basins in the state have underlying
perforated piping to carry off what is known as " tail water. "
The purpose of this piping is to keep the farmland above
from becoming waterlogged. This tail water is frequently
full of fertilizer runoff, and sometimes also has naturally
occurring, but very problematic, minerals in it such as
selenium and arsenic. Today in the Central Valley, this
water is channeled into huge evaporation ponds where
it is evaporated off and lost. In other places, this water is
drained into the sea. It is now, however, finally practical
to fully clean this water for reuse. We believe there
may be 100,000 acre-feet per year or more of this
tail water being wasted today across the state.
And then there's what is known as produced
water - water that is naturally mixed with the
oil that is being pumped out of the ground. In
California, there are about 400,000 acre-feet
per year of produced water that could be
thoroughly cleaned and used for agriculture.
We already have many thousands of acres
in the state that have been irrigated
with produced water for many
years. Recently published
California university multiyear
studies now show
that there are no
detectable harmful impacts on the crops as long as the
produced water has first been cleaned properly of the
organics and salts that are in it.
By using innovative new zero brine, renewably powered
desalination technologies, it's now finally becoming possible
to cost-effectively clean all of these " impaired " water sources
so they can be safely used for agriculture.
There are a lot of existing stereotypes about desalination.
Many people think desalination technology only involves
ocean water, but it can be used on any salty or contaminated
water source. Ocean desalination has a well-deserved
reputation for being highly expensive ($2,400 per acre-foot
and higher), as it requires very expensive infrastructure and
consumes a lot of power. It also generates lots of highly salty
brine, which then gets dumped back into the ocean with
problematic environmental effects. In fact, it's this traditional
generation of brine by desalination technologies (the salts in
half or more of the water are pushed through membranes into
the remaining volume of water, known as the " brine " ) that
has blocked almost all inland desalination, because getting
rid of the generated brine by trucking it to an ocean outfall
for disposal, or to an inland deep well injection site, can be
extraordinarily expensive. It also wastes the water in the brine.
The great news is that with the latest technologies,
zero brine is possible when desalinating any of the above
impaired water sources. Brine can be taken from an older
