During one of this winter’s frequent storms, sheets of rainwater spilled from roofs, washed across sidewalks and down gutters into a sprawling network of underground storm drains that empty into the Los Angeles River channel. (Same goes for Ballona Flood Control Channel. Billions of gallons of rainwater
Thanks to these natural runoff filtration structures, we don't have to choose between great landscape aesthetics and eco-friendly design.

Bioswales are a unique green solution to the problem of contaminants in stormwater runoff. Bioswales slow down and collect polluted stormwater runoff and then filter it prior to returning it into the water cycle. They accomplish this filtration with the help of two natural processes: filtering water by passing it slowly through porous material, along with phytoremediation, where plants remove contaminants. Bioswales can contain sand, compost, and rock trenches along with native species of plants, which are adapted to local conditions. The inclusion of local plants is also important on an aesthetic and educational level: these plants blend in with the local environment and can serve as a tool to educate the public on issues of native biodiversity. Bioswales are a small but necessary remedy to the unmitigated proliferation of paved surfaces in our car- centric world. Parking lots especially create massive concrete plains incapable of absorbing or filtering stormwater.

Rain Water Capture and Reuse discussion by Jeanette Vosburg at the Culver City Garden Club 9.2.15. Capturing rainwater has saved 40% on the water bill from 2014 and 2015. Jeanette suggests choosing one or two of her ideas on your own property. 41 Minutes
Farmers and Kern County, California Commissioners' Meeting: Well Water Contamination California grows 2/3rds of the nations produce. Some farmers in the Central Valley farmers are buying recycled oil water from Chevron. Kiran visits the Central Valley's Cawelo Water District where the drought is causing farmers to use recycled oil water to irrigate their crops. She takes in the smells so you don't have to. This water is toxic. It can have 1 or more of 450 chemicals that oil companies use to bring oil to the surface. Hungry Now? Published on Feb 2, 2016.
There are many reasons to plant a home garden. Nothing tastes more delicious than a hand picked tomato, orange, blackberry, basil, and the list can go on forever. Eaten at the peak of perfection, you truly appreciate the bounty of earth and the importance of water in the growth cycle.
Oilfield "fracking" is a new form of pollution that is the longest lasting damage to the land, worse than salting the ground to prevent plants and animals living on it, or a man growing food for his family, neighbors and you and me. Fracking permanently poisons, yes poisons, the underground water, permanently poisons the air, yes the air, as natural gas and associated poisonous gases seep out of the water table to harm all life at ground level, your pets, crawling children, and you and me. Fracking leads to water and air plumes of poisons stretching miles into all homes and bodies of wate
