BP announced Sunday that they were collecting more than 10,000 barrels of oil a day from the recently placed containment cap. BP’s next step is to close the vents on the cap that are still allowing streams of oil to escape. U.S. Coast Guard Adm. Thad Allen tempered the good news, however, saying “There will be oil out there for months to come.”
Beachgoers will likely have to deal with oil on the shores well into the fall, which brings up the question: Is it safe to swim? Health Departments of three states have already issued swim advisories urging people to steer clear of any waters with visible oil. One health expert said swimmers should avoid oily water because the effects of exposure to oil and dispersant are not currently known.

The United States Geological Survey studied the effects of urbanization of nine metropolitan areas to look at the impact on algae, aquatic insects, fish, habitat, and chemistry. They found that development degraded the areas.
The health of a waterway is entirely dependent on the status of its riparian zone, the area of land from which storm water flows. In urban areas, impervious surfaces like roads, buildings, and parking lots cover more of the riparian zone. During a storm, water is unable to penetrate the ground surface to recharge aquifers and instead flows to streams and rivers through storm drains.
However, storm water in urban environments is a major source of pollution and is detrimental to riverine ecosystems. The water carries with it all of the deposition of human activities including lawn fertilizer, rock salt and calcium chloride pellets, spilled gasoline and other automotive fluids, litter, and other industrial pollutants.

Attorney General Eric Holder, during a visit to the Gulf today, announced that civil and criminal investigations about the spill are under way. Prosecutors are examining thousands of pages of e-mails, repair logs and other documents to see whether oil giant BP and its contractors have willfully violated federal safety regulations.
“If it turns out to have been misleading conduct, false statements, concealment or withholding of information, then there’s a whole laundry list of other charges that could materialize,” said David Uhlmann, former head of the Justice Department’s environmental crimes section.
During the announcement, Holder said prosecutors will be focus on violations pertaining to the Clean Water Act, Oil Pollution Act, Migratory Bird Treaty, and the Endangered Species Act.
President Obama has asked Congress for $10 million to finance the investigations.

Chemicals make up a small percentage of the fluids used in the controversial oil and gas drilling technique called hydraulic fracturing. But when well operators blast millions of gallons of water into wells to free natural gas, that one to five-percent chemical makeup can turn lethal.
