Why Fish Need Water

Now we have some new science, sewage science.

Jan 13, 2017

We've been trying to tell California's water bureaucrats that there's a lot more to fish health than pouring our river water on them, particularly in the Sacramento-San Joaquin River Delta.  The Sacramento region discharges millions of gallons of partially treated sewage into the Delta.  That's just Sacramento.  Another dozen cities also discharge millions of gallons into the heart of the Delta and the discharges have grown as the cities have grown.  The wastewater contains significant amounts of ammonia and numerous trace elements of pharmaceuticals (PPCPs – Pharmaceuticals and Personal Care Products. PPCPs represent dozens of constituents spanning a cross section of our daily lives, from that first cup of coffee in the morning to preion medication to soaps, fragrances and sunscreen.) that pass through our bodies.  Sacramento has been ordered to clean up their act, but have been given until 2023 to do so.  Until then farmers will continue to be blamed for the health of the Delta Smelt.

The water bureaucrats say they want to use the best science to bring back the health of the Delta ecosystem.  All their science tells them to do is to just keep adding more water.  Their science apparently doesn't think the sewage is a problem.  

Now we have some new science, sewage science.  In the article below from Science Daily, they have concluded that "upgrades to a wastewater treatment plant along Ontario's Grand River led to a 70 per cent of fish that have both male and female characteristics within one year and a full recovery of the fish population within three years, according to researchers."

They go on to say "endocrine disruption in water systems is a worldwide phenomenon. Estrogen in birth control pills and other chemicals that mimic natural hormones are known to impact fish health in trace amounts as low as one part per trillion, far below what conventional wastewater treatment can typically remove."

We recommend the California water bureaucrats take a look at the science and clean up the Delta sewage instead of just adding water.
