Why is runoff from storm drains a problem?
Storm drains direct runoff from urban areas to the ocean. While they do not normally contain sewage, water in storm drains can contain disease-causing pathogens. Depending on the amount of flow, the discharging storm drains can affect ocean water quality several hundred yards from the discharge point. Much greater areas may be affected following major rainstorms. When this happens, beaches are posted with the appropriate sign, warning the public to avoid storm water and runoff. After a rainstorm, the ocean waters impacted by the storm should be avoided for at least 72 hours (Health and Human Services).
As seen in the video posted below, storm drains lead directly to the ocean. Rain should be the only thing being washed into the drain, yet there is also a constant flow of rubbish. On September 23 and 24, work crews for the Los Angeles County's Department of Public Works collected 175 tons of material that would have led to the ocean. Most of our beaches seemed to have less debris, but that was only due to lack of rain. The weekend rain brought out the debris, and we are fortunate that some of the material was collected by the mouth of the Los Angeles River. This trash was stuck in the boom collection systems. The city had built it to try and protect runoff from entering the ocean. Although a lot of debris were collected, many debris will find its way to Long Beach's shoreline. With the ongoing lack of water circulation due to the breakwater, this rubbish will circulate throughout the Long Beach harbor and maintain poor water quality.

That picture is pretty nasty. I like the amount of information you give in each post, it really helps me stay informed. Maybe you could take first-hand pictures of the coast and post them on your blog. That woud certainly increase your credibility.
I agree that the water is definitely disgusting, and I do not think that many people would want to swim in the water. Also, thank you for the advice as far as credibilty. I will try to get a few photos up.
