In general, yes.
The sometimes iridescent "oil film" seen on water surfaces may be crude oil, which is modestly toxic to people; used motor oil, which is much more toxic and carcinogenic; gasoline, which is carcinogenic (especially premium unleaded grades); or other hydrocarbon subsances that may be poisonous or unhealthful. There are other film-forming substances that may appear on water, that may be harmless, but a swimmer won't be able to differentiate these from the toxic slicks.
If oil films or slicks are seen, it is best not to swim in or drink the water. If swimming or drinking are unavoidable, stay away from the oil slick, or pour it off before drinking. Make every effort to avoid inhaling or swallowing the slick material. If the oily material gets on the skin, bathe with mild dish detergent (such as Palmolive) to remove it. If swallowed, take 2-3 tablespoons of mineral oil by mouth, which should eliminate the material from the system, and consult a health practitioner if available.
The water quality of the beaches in Louisiana, Alabama, Mississippi and Northern Florida are being very actively monitored by the EPA, and state/ local health officials. They will close the beaches if they feel there is a health hazard. Outside of these area, as of May 16, the gulf coast beaches are safe.
simple.... because the jelly fish will sting you
The water is too dangerous to swim in.
Runoff is dangerous because there are fertilizers, pestcides manure oil dieases, leaked sewage,sediment, and trash. Would you swim in that?
Yes, the lightning will be attracted to the water and it could electricute you.
a bear
The oil is much thicker and stickier
The oil flows out of the ground as if it were a child gliding out of the water after a long swim.
Yes any water is dangerous. You can drown you could get leaches swimmers itch, malaria. But it's pretty safe if you know how to swim if you swim in the designated swimming area. And take a shower right after.
