September flooding and E. coli bacteria sampling

Oct. 1, 2009

Indicator bacteria levels in the Chattahoochee River increased substantially during and after the epic flooding that struck Atlanta on September 22-23, 2009. On September 14, 2009, the Upper Chattahoochee Riverkeeper collected water samples from the Chattahoochee River at West Paces Ferry Road in Vinings that contained an Escherichia coli (E. coli) bacteria density of 75 most probable number per 100 mL. Multiple water samples collected from the river at West Paces Ferry Road by the USGS on September 23, 2009 were nearly 200 times higher than the value measured on September 14, 2009. The USGS sampled three additional sites downstream from Vinings on September 23, 2009.

Sample date  / Location  / E. coli density (most probable number per 100 mL)

9/14/2009 Chattahoochee River at West Paces Ferry Rd   75

9/23/2009 Chattahoochee River at West Paces Ferry Rd   14,000

9/23/2009 Chattahoochee River at Interstate 20   18,000

9/23/2009 Chattahoochee River at Fairburn, GA   3,900

9/23/2009 Chattahoochee River at Whitesburg, GA   1,100

The National Park Service and the Upper Chattahoochee Riverkeeper collected water samples from the Chattahoochee River and Big Creek on September 28 and 30, 2009. These values show substantial decreases in E. coli density within 7 days of the flood.

Another good reason for Green Infrastructure!

It’s Raining, It’s Pouring…

February 10th, 2009 10:35am PST

Posted By Elizabeth Cutright 1 Comment WE Mag

It’s been a rainy couple of days here in Santa Barbara, just enough to fill up a few puddles and trigger a few freeway fender benders.  Spring, or perhaps “pre-spring,” showers in southern California always serve to highlight a few normally dormant concerns: mudslides in last season’s burn areas, flooding as a result of clogged storm drains, and beach contamination due to runoff.  But as I watched the rain splash along the street and heard it tripping down the gutter, I once again lamented the fact that rainwater catchment is still not as popular as it should be.

Last fall, I attended the American Rainwater Catchment Systems Association’s (ARCSA) annual conference in Santa Monica, CA. The theme of the conference was “Water—The New California Gold Rush,” and a variety of professional voices presented ideas great and small regarding the justification for and the installation of rainwater catchment systems not only in California, but also throughout the country.

While I mentioned this conference in a previous blog, some of the interesting facts I learned bear repeating:

– Trees are rainwater harvesting machines!  An oak tree can collect and treat 57,000 gallons of stormwater.

– If all of Los Angeles’s rainwater was collected, it could supply half of all the state’s water needs.  (So far, six projects in Los Angeles capture 1.25 million gallons of water every time the city gets an inch or more of rain.)

– The single largest use of electricity in the state of California?  Pumping water to the Los Angeles basin.

– Although the typical human needs around 50 gallons of water per day, the US consumes approximately 150 gallons per person per day.

It seems as if rainwater harvesting is a no brainer, so why isn’t it more widespread?  Do you think communities should do more to promote rainwater catchment as part of a comprehensive water conservation program?  Or is rainwater catchment just a drop in the bucket?

Philadelphia Proposes Major “Green” Storm Water Plan

U.S. EPA representative: “This is the most significant use of green infrastructure I’ve seen in the country”

September 29, 2009 Storm Water Solutions

The city of Philadelphia has announced plans to invest $1.6 billion in managing and treating storm water with “green” solutions, namely rain gardens, green roofs, tree plantings, rain harvesting barrels and porous pavers.

“This is the most significant use of green infrastructure I’ve seen in the country, the largest scale I’ve seen,” Jon Capacasa, regional director of water protection for the U.S. Environmental Protection Agency (EPA), told The Philadelphia Inquirer. “We commend Philadelphia for breaking the ice.”

The plan–totaling 3,369 printed pages–is theoretically workable, according to Natural Resources Defense Council water expert Nancy Stoner. “It’s the scaling up that’s new,” she said to the newspaper. “That’s what’s really exciting.”

City officials have been working on the plan for about 12 years. They ruled out separating the city’s combined storm water and sanitary sewer lines early on; the option was too expensive. Major sewage plant expansions and constructing massive underground tunnels, the next options considered, were deemed inefficient and costly.

The newly proposed green infrastructure proposal would raise rates a bit, but it would also attract grants and private investment. City officials estimate that this plan would reduce overflows by 80%, but the EPA has expressed that it wants Philadelphia to demonstrate an 85% reduction.

The Hydro-Illogical Cycle

“We welcome the first clear day after a rainy spell. Rainless days continue for a time and we are pleased to have a long spell of such fine weather. It keeps on and we are a little worried. A few days more and we are really in trouble. The first rainless day in a spell of fine weather contributes as much to the drought as the last, but no one knows how serious it will be until the last dry day is gone and the rains have come again.”

(from I.R. Tannehill, Drought: Its Causes and Effects, Princeton University Press, Princeton, New Jersey, 1947)

 

Unlike other natural disasters, drought does not have a clearly defined beginning and end. As a result, our reaction to drought traditionally has not been timely.

Rain Barrels

Rain Barrels are a great introduction to the world of Rainwater Harvesting. However, they are only good for small gardens or patios. If you are just suplimenting the occasional dry week great, but if you want be ready for the next drought or long dry period get a tank. Look at your local rainfall history. Start planning 3-4 weeks of reserve and leave room for another tank down the line.

Also take a look at my rain barrel page at the top to find out good tips on building your own or what to look for when you buy one. Remember, have at least one 1 1/2″ overflow directed away from the house and ending in an area that will not erode. Secondly, make sure your barrel is opaque so not to allow sunlight to cause an algae bloom.

Federal Judge Rules Against Ga. in Water Litigation

By Bill Rankin

The Atlanta Journal-Constitution

A federal judge on Friday ruled the U.S. Army Corps of Engineers has been illegally reallocating water from Lake Lanier to meet metro Atlanta’s needs, but he’s not turning off the tap just yet.

The judge overseeing the high-stakes case wants a political solution and is sending the fight to Congress.

In the meantime, the current withdrawal levels from Lake Lanier will be allowed to stay the same — but not increase, U.S. District Judge Paul Magnuson ruled. And if a political solution cannot be worked out in three years, the judge said, his order will take effect.

This means the metro area will not be allowed to use Lake Lanier as its primary source of water supply.

“Thus…only Gainesville and Buford will be allowed to withdraw water from the lake,” Magnuson said in a 97-page order. “The court recognizes that this is a draconian result. It is, however, the only result that recognizes how far the operation of the Buford [Dam] project has strayed from the original authorization.”

Magnuson, of St. Paul, Minn., was picked in 2007 to decide the almost two-decades-old tristate water wars case involving Georgia, Alabama and Florida.

His ruling handed the metro area a crushing legal defeat. The judge found that the Corps of Engineers should have obtained congressional approval before allowing Lake Lanier to be the metro area’s primary source of water supply.

In a joint statement, Georgia senators Johnny Isakson and Saxby Chambliss acknowledged it is now up to Congress to reach a compromise.

“We will work tirelessly to reach an agreement that is in the best interest of Georgia while at the same time respecting the interests and concerns of Florida and Alabama,” the senators said. “This is a huge challenge, but it is a challenge we must meet.”

Alabama Gov. Bob Riley praised the ruling, saying he hopes it leads to renewed negotiations between the three states and a “fair and equitable” agreement.

“Atlanta has based its growth on the idea that it could take whatever water it wanted whenever it wanted it, and that the downstream states would simply have to do with less,” Riley said. “Following the court’s ruling today, this massive illegal water grab will be coming to an end.”

Gil Rogers, senior attorney with the Southern Environmental Law Center, said the ruling puts Georgia in a much weaker negotiating position with respect to Lake Lanier water rights.

“This is a real wakeup call for the metro Atlanta area,” he added. “Drought or no drought, this area can no longer take water for granted and should move as quickly as possible to sustainable water management practices that do not involve controversial reservoirs.”

Magnuson said he was sympathetic to the plight of the Corps of Engineers because it has to deal with competing claims to Lake Lanier’s water — a finite resource.

But the judge said the Corps’ reallocation of Lake Lanier’s water without congressional approval was illegal and in violation of the Water Supply Act. And Magnuson said it was “beyond comprehension” that the Corps’ current operating manual for the Buford Dam is more than 50 years old.

He encouraged the Corps to update its water supply plans so those in the Apalachiocola-Chattahoochee-Flint (ACF) river basin can determine how the operation of Buford Dam will affect their future interests and whether it can meet their water needs.

But Magnuson also said the blame cannot be placed solely on the Corps’ shoulders.

“Too often,” Magnuson wrote, “state, local and even national government actors do not consider the long-term consequences of their decisions. Local governments allow unchecked growth because it increases tax revenue, but these same governments do not sufficiently plan for the resources such unchecked growth will require.”

Nor do individual citizens consider frequently enough their own water consumption, absent a crisis such as the recent drought, the judge said.

“The problems faced in the ACF basin will continue to be repeated throughout this country, as the population grows and more undeveloped land is developed,” Magnuson said. “Only by cooperating, planning and conserving can we avoid the situtations that gave rise to this litigation.”
