quote:Originally posted by fossilfreedom Mystery brews along the James White foam appears along the river here; the cause is unknown Jun 7, 2006 BY REX SPRINGSTON TIMES-DISPATCH STAFF WRITER A mysterious white foam coated much of the James River in Richmond VA[8)] yesterday morning before dissipating a few hours later. No one knows the source of the foam. It apparently caused no damage. No fish turned belly up. The lacy foam, resembling soap suds, covered nearly the entire river yesterday about 8 a.m. from the so-called Z dam at Williams Island to just above the Huguenot Bridge, said James River Park manager Ralph White. That's a distance of about a half-mile. By late morning, the white foam had dissipated, but a brownish scum hugged the shoreline where the water moved slowly. "This morning it was massive, and now there's nothing," said White, standing along the James in South Richmond about noon. He was just upriver from the bridge. White said he didn't know if the foam was caused by the natural decay of organic matter, or by a pulse of pollution of some kind. He said it didn't look natural to him. White said there had been four or five similar incidents in the past three weeks but not as extensive. "This morning I was aghast, because it was all the way across the river." Figuring out a strange foam is like fixing a car's weird noise you've got to be there. The state Department of Environmental Quality could not send an investigator before the foam went away. "If we are not there to actually see it, it's difficult to reach a conclusion" as to the cause, said DEQ spokesman Bill Hayden. Wayne Huggins, executive director of the Virginia State Police Association, stood beside some of the brown scum as he did a little midday fishing at Huguenot Flatwater, just above the bridge. "I come down frequently on my lunch hour, and I don't remember seeing this before," Huggins said. By early afternoon, people were wading and splashing just below the formerly foamy area. For now, the foam is a mystery. Contact staff writer Rex Springston at rspringston@timesdispatch.com or (804) 649-6453. James River foam likely a natural phenomenon Jun 9, 2006 DEQ theory suggests origin may be organic chemicals flowing through rapid areas BY REX SPRINGSTON The mysterious white foam on the James River resurfaced yesterday, then quickly got a lot less mysterious. "It appears that this is natural," said Bill Hayden, a spokesman for the state Department of Environmental Quality. According to a preliminary theory, DEQ scientists say unusually warm, dry weather in March and early April promoted extra growth of plants and algae in the James, Hayden said. Those plants decay, releasing natural organic chemicals. "When that material flows through the rapid areas, that tends to aerate it and causes the foam," Hayden said. The foam forms in the morning, then dissipates as the sun warms it, Hayden said. The DEQ continues to investigate. The agency awaits lab results of a water sample taken last week. People have spotted the foam about a half-dozen times this spring, including Tuesday and yesterday. It has caused no apparent harm, but it has mystified many. State and city health officials referred questions yesterday to Hayden. About 9 a.m. yesterday, patches of the foam flowed past the river's south bank and extended about a third of the way across the river. The foam extended from just above the Huguenot Bridge to about a mile below it before dissipating about midday. The foam should have little effect on the Capital One Adventure Games, which will take place June 17-18 on Brown's Island. Seven of the games' 11 events take place on the James, and two involve swimming. The Splash One-Miler at Robious Landing Park is on June 17, and the XTerra East Championship, which includes a 1,200-meter swim downtown, is June 18. But Sports Backers, which organizes the Adventure Games stop in Richmond, is not worried about the foam. "Unless we hear that it is harmful, the events will go on as planned," Marketing Director Scott Shricker said. Just above the Huguenot Bridge yesterday, kayaker Jim Struve of Chesterfield County touched the foam and said it didn't feel greasy or strange. Struve said he was curious but not alarmed. Near Struve stood Chuck Frederickson of the James River Association, an environmental group. He serves as riverkeeperfor the James River -- basically the eyes and ears of the people. Frederickson said he had seen similar foam at Watkins Landing in Powhatan County earlier in the morning, but on the north side of the river. He saw no foam at Robious Landing in Chesterfield County, then found it again in Richmond. Those intermittent appearances indicate the foam might be natural and not the result of pollution that's seeping in somewhere, Frederickson said. There are lots of things besides foam in the James. The state lists the river in the Richmond area as technically unfit for swimming because of fecal bacteria from sources that include the waste of dogs, geese and probably cattle. Rains wash the waste into the water. Water tests in Richmond show the river is fine for swimming most days, but bacteria levels have been high often enough to put the river on the state's so-called dirty-water list. Health experts say people should be OK as long as they don't swim during or shortly after a rain. Contact staff writer Rex Springston at rspringston@timesdispatch.com or (804) 649-6453.

We should be very carefully watching these rapids and waterfalls because foaming is often caused by natural surfactants…such as GET THIS…FATTY ACIDS! By watching rapids and waterfalls for unexplained foaming we could identify heretofore unknown high oil producing organisms including alage. © 2006 Patrick Ward 10 June 2006 With Best regards FREE ENERGY Patrick Ward Richmond VA fossilfreedomATyahoo.com fossilfreedom@yahoo.com fossilfreedomATyahoogroups.com fossilfreedom@yahoogroups.com biogasolineATyahoo.com biogasoline@yahoo.com biogasolineATyahoogroups.com biogasoline@yahoogroups.com http://www.fossilfreedom.com http://www.state.me.us/dep/blwq/doclake/surface.htm#foam Foam Description: Foam "soap suds" on the surface or along the shore. Analysis: Foam along the shore probably does not indicate pollution from laundry waste. Virtually all detergents today are a biodegradable form which is easily broken down by bacteria. Most foam is natural. Foam is created when the surface tension of water is reduced and air is mixed in, causing bubbles. Many natural organic compounds will reduce surface tension, including those from decomposing algae and fish. In a lake, these organic compounds are mixed with air by wind and currents to produce foam. Large quantities of foam are often found on windward shores, coves and in eddies. Natural foam has a somewhat earthy or fishy aroma. Detergent foam, in contrast, will have a noticeable perfume smell. http://www.potomacriver.org/info_center/reporterpdf/2004/v604.pdf#search='algal%20foam' http://www.duluthstreams.org/old_stuff/explore/foam.html Piles of Foam? It's a natural phenomena! Blankets of foam below waterfalls, rapids and riffles and accumulating in backwater areas and pools are a common feature of northland streams, particularly in the Spring. A frequently asked question is: "What's polluting our stream? It's covered with foam! What is it? The foam found in lakes and streams is usually natural. Wind-driven currents frequently create parallel streaks of foam in open water that accumulate along windward shores and in coves. In streams it's formed from the turbulence of waterfalls and rapids.It is usually caused by naturally occurring dissolved organic compounds in the water that act as "surfactants" and reduce the surface tension of the surface film of water. This allows fine bubbles and froth to form, accumulate on the surface, and be moved into calm areas by wind and water currents. Natural or Man-made? Most of the compounds that lead to foam are fatty acids that come from decomposing plants and animals and are chemically similar to additives in soap products. People often blame shoreline foam on detergents, but they usually don't create long-lasting foam and tend to quickly lose their sudsing ability. Surfactants are the key active ingredient of detergents and increase the wetting and cleaning power of water. Industrially polluted effluents that caused great masses of foam were much more common in the past before about 1964 when the detergent industry introduced a new surfactant that greatly reduced wastewater foaming. The Clean Water Act of 1972 led to further changes in the formulations of soap and detergent, wastewater treatment and the elimination of most of the worst offenders in point sources. Local sources can still produce excess foam but would likely be diluted relatively quickly. A number of environmental agencies report that natural foam usually has an earthy or fishy smell while detergent foam has a perfumy fragrance. Environmental consequences The foam itself, if natural, is simply an interesting part of the ecosystem. However, if it is derived from human activities, there may other pollutants associated with it that may affect human and environmental health. If detergent-based, the phosphorus in the product can lead to eutrophication effects which include excess algal and plant growth, higher suspended solids and reduced oxygen levels. It may also be an indication of excess storm water runoff which can contribute a variety of pollutants, including some toxic compounds. Since foam is most likely to be produced during periods of high runoff, the public should treat it with some degree of caution because it may contain disease causing organisms from sewer overflows and stormwater runoff, in addition to chemical contaminants. Unbelievable amounts of foam were generated below a dam on the Raisin River in Dundee, Michigan in March 2003. The fluffy stuff piled about 12 feet high from bank to bank. Although the river is known to generate considerable foam in the spring, this year was exceptionally "impressive." The Michigan Department of Environmental Quality believes that a confluence of factors contributed to a very high volume of foaming incidents and complaints in March 2003, not only at this site but in many different warm water river systems. A drier than usual winter and early spring may have contributed to a build up of the natural factors that cause foaming. There was no conclusive evidence linking the suds to sanitary sewer or combined stormwater runoff and there was no correlation at all to the very limited CSO/SSO's this spring around the River Raisin.

Hopefully this is not a harmful algal bloom (HAB) from some type of cyanobacteria. Considering that the latest tests showed 1.9 parts of phosphorus per million of water just above the Huguenot Bridge, I would assume the State Department of Environmental Quality will track the source of this phosphorus before very long. Just out of curiousity, has the James River ever had a history of problems with Eurasian Watermilfoil? TJ..
quote: Some types of algae can be harmful to people and fish, although the most harmful types occur more often in salty water, DEQ officials say. The water just below Hopewell is fresh. The resort town of Colonial Beach temporarily closed its beaches last summer when a toxic form of algae, which could cause skin rashes and upset stomachs, contaminated the slightly salty Potomac River. The nutrient overload in the James and the hot, sunny weather of the past few days provided perfect conditions for the algae to grow, said Alan Pollock, the DEQ's water-quality director. Pollock said he expects the James River outbreak to last a week or so.

Although Harmful Algae Blooms (HAB) are probably more common in brackish or salty water, they do occur in fresh water. Species of cyanobacteria (blue-green algae) that form HABs in fresh water are listed here. Microcystis Aeruginosa Anabena Circinalis Anabena Flos-aquae Aphanizomenon Flos-aquae Cylindrospermopsis Raciborskii I would forward this information to Rex Springston and pursue the Department of Environmental Quality to find out what type of blue-green algae blooms have been discovered in James River.
