across anything like that. cornell: man arresting drivers, but santa rosa police taking it to the next level by suing organizers for pollution. >> the rubber degree and tire debris going into our storm drains and polluting our waterways. cornell: police chief john cregan says the cities going after 13 driver and organizers by using the department of fish and wildlife regarding water pollution, which restricts the dumping of motor vehicle parts. >> we are trying to be creative and utilize the tools around us. we are certainly going to be in uncharted territory with us, but we are proud of our partnership with the santa rosa city police department. cornell: santa rosa is seeking funds of 25,000 dollars from each department. the city is also impounding cars that have been used in sideshows

and installed bumps and traffic delineators in streets where sideshows typically happen. >> any time you provide other outlets for them to use that energy, it makes it a little more difficult. cornell: when it comes to nonsentient street takeovers, there's a new zero-tolerance policy in town. >> one thing we want to make very clear with all the efforts we are making is that we will not tolerate this dangerous and illegal behavior on the streets of santa rosa. declare victory, but santa rosa police say they have already seen a significant decrease in sideshow activity so far this summer, and they believe their enforcement is working. we will see what happens. larry: interesting approach. thank you. chp detectives a investigating a deadly freeway shooting friday night on westbound 24 east of

>> i talked to them yesterday and this morning, and they are developing a strategy to most effectively do this because it could take time. leslie: meanwhile, the county health department is asking anyone who visited this spot in the last two weeks to assess themselves for symptoms like fever, cough, shortness of breath, and to contact their health care provider and the county communicable disease department. legionnaires' disease is caused by a bacteria that is aerosolized and water droplets. officials say the indoor spa with waterfall provided a high risk environment for the illness. they are looking into other potential shared ventilation systems within the building. the owner is cooperating with the investigation. one man recovered after testing positive for legionnaires in june at the same spa. results of more detailed water testing are expected later this week. stabbing deaths of a woman and her great-grandsonork isolated

if they go beyond five are sent. >> i'm not opposed to paying more. i grew up in a union household. i know how much every dollar matters, but we also don't want to be in a position where we are either over committing and then doing layoffs in a couple of years or -- and this would be true if we go much beyond 5% -- cutting core services like library hours and police and fire services. >> san jose city workers will head to the picket lines for a three-day strike starting tuesday, august 15 through thursday, august 17. kristen: san jose is not the only city in california that could soon feel the impact of a city-wide strike. more than 11,000 los angeles city workers are planning to walk off the job for 24 hours starting at midnight tonight. this would heavily affect the ports and airports in the l.a. area. the port of los angeles is the largest container port in north america. larry: an investigation now underway into the deadly midair collision of two firefighting

>> floral and nurseryro account for 60% of the production in this county followed by vegetables. these two commodities were the hardest hit. >> we did find that our crop report was down. i'm definitely concerned with some of the trends and the numbers going down. but i know it is a resilient community, industry. it is diverse on the diversity i feel helps this industry survive into the future. >> historic rain at the beginning of the year gives farmers hope, but it was also a wake-up call to keep innovating ahead of climate change. >> we do dry farming early in the season. we will plant crops, usually english peas or beans, and the rains that fall will give us enough water to be able to get a crop.

naked i, under a sophisticated microscope you will see a chain of molecules. >> they linked together to make the framework. dan: they are extremely porous, with a surface area roughly the size of a football field and just a small amount. >> that is the space into which one combines gases like hydrogen for hoarders and storage, -- hydrogen storage, carbon from the air, or in this case water. dan: the question for zach and his colleagues was whether it would be efficient enough to condense water molecules from the hyperdrive desert air. in the baking sun, they watched and waited for the first time he drops to appear. >> and finally it just dropped, dropped. about 60 seconds or so. as soon as i saw the drop, i said, it works. dan: with the latest results, they hope the water harvester can impact populations in the
