Colorado Parks and Wildlife has confirmed a group of wolves is living in northwest Colorado. According to CPW, wildlife officers investigated an animal carcass surrounded by large wolf-like tracks Sunday in the northwest corner of…

As 2017 gets rolling, we are set to swear in a new President.  The politics are already interesting.  The question is what will change, when and how.  For example there has been an ongoing discussion of infrastructure bills, but aside from WITAF approval, little clear direction has been forthcoming.  We only know that private sector participation will be encouraged.  Of course virtually all projects constructed in the public sector are constructed by private contractors, so how/if that will change is unclear.

It is also unclear which industries will be affected.  There are already comments about not pursuing he renewable energy opportunities  – China sees 13 million jobs in the coming 5 years as their economy cranks up to meet the needs.  They are contributing $360 billion to enhance this sector.  I have previously blogged about potential opportunities in the US to grow renewables.  But they are just like recycling in the 1970s.  Recycling needed to be subsidized until such time as the facilities and processes were in place to make it competitive.  Now for steel and aluminum, it is less costly than virgin iron or bauxite.  That has several benefits to the economy and the environment.

I have previously suggested that those who do the research, develop the solutions and control the patents tend to rule the economy.  The US did in throughout the 20th century.  Energy is the 21st century opportunity and I would hope we don’t cede that elsewhere due to politics.  13 million jobs would really help places in rural America and place like Detroit and Flint which have the workers.  It may be that instead of the federal government doing much in this arena, the state and local officials will lead the charge.  California has been successful to a degree in this regard.  Let’s see if making money will “trump” the politics of oil. That would be good for a lot of local governments that have workers and factories, but not jobs.  That would help people like those in Flint.  And it would help their utilities.  Let’s work on this with our local officials

Every water body will be different but in southeast Florida there are a couple options for Lake Okeechobee’s waters.  One option has been in discussion for years – buy back the EAA lands and restore the Everglades flow.  That has two benefits – improved water quality, and less potential for east-west releases.  The downside is cost.  But the sugar industry knows that the muck layer is decreasing and there are plans to develop the EAA into hundreds of thousands of housing units.  That was not the intention in the 1940s when the EAA was created, but trying to stop someone from developing land, especially when the lake communities are challenged economically, is difficult.  Buying the land would remove it from production, but decrease tax revenues.  And it would need to be managed with no guarantee that it would cleaned up quickly.

The alternative?  The South Florida Sun-Sentinel had a front page article that is a little scary.  The figure below is reproduced from that article.  The discussion was if there is no conservation/public purchase of land, Florida may look very different.  The impact of not buying the land is development.  More people.  More taxes.  More stormwater.  The fertilizer does not go away – it now fertilizes lawns and golf courses.  Add wastewater, and human activities.  We find that urban living and farming can have similar impacts from a nutrient perspective.  So development may exacerbate the problem and given that our modeling indicates that sea level rise imperils inland communities from groundwater, this is not a solution to coastal risk.  Given limitations with local governments inland, it may create a larger crisis.  All there things need discussion, but the question is – will the algal issues on the coast improve?

graphic-of-development worse?

The most important parameters regulating algal growth are nutrient quantity and quality, light, pH, turbulence, salinity and temperature. Light is the most limiting factor for algal growth, followed by nitrogen and phosphorus limitations, but other nutrients are required including carbon. Biomass is usually measured by the amount of chlorophyll a in the water column.  Water temperature influences the metabolic and reproductive rates of algae. Most species grow best at a salinity that is slightly lower than that of their native habitat,  The pH range for most cultured algal species is between 7 and 9, with the optimum range being 8.2-8.7. Through photosynthesis, algae produce oxygen in excess of respiratory requirements during daylight hours. Conversely, during low light or nighttime periods algae respire (consume) dissolved oxygen, sometimes depleting water column concentrations. Thus, high algae concentrations may lead to low dissolved oxygen concentrations.

A common solution for algae is copper sulfate.  Copper Sulfate works to kill the algae, but when it dies, it settles to the bottom of the water body where it becomes a carbon source for bacteria and future algae.  One will often see shallow ponds with rising algae.  But there is significant concern about copper in coastal water bodies.  Copper is toxic to marine organisms so USEPA and other regulatory bodies are considering the limits on copper use.  Such a limitation would severely limit options in dealing with algal blooms near coastal waters.

Mixing is necessary to prevent sedimentation of the algae, to ensure that all cells of the population are equally exposed to the light and nutrients.  So oxygenation can help (it also mixes the water.  The depth of south Florida water bodies is problematic (shallow and therefore warmer than normal).  But oxygen will help microorganisms on the bottom consume the carbon source on the bottom, which might slow algal growth.  Analysis is ongoing.

Two other conditions work against controlling blue-green algae outbreaks: climate change and political/regulatory decision-making.  Lake Okeechobee has routine algal blooms from the nutrients introduced from agriculture and runoff around the lake, which encouraged an artificial eutrophication of the lake years ago.  It continues today.  Warmer weather will encourage the algal blooms in the future.  The decisions to discharge the water without treatment is a political one.  From a regulatory perspective, algae is seen as a nuisance issue, not a public health or environmental issue.  But algal blooms consume oxygen and kill fish, so the ecosystem impact is considerable – it is not a nuisance .

The term algae encompass a variety of simple structures, from single-celled phytoplankton floating in the water, to large seaweeds.  Algae can be single-celled, filamentous or plant-like, anchored to the bottom.  Algae are aquatic, plant-like organisms – phytoplankton.  Phytoplankton provides the basis for the whole marine food chain. Phytoplankton need light to photosynthesize so will therefore float near the top of the water, where sunlight reaches it.  Light is the most limiting factor for algal growth, followed by nitrogen and phosphorus limitations), but other nutrients are required including carbon, silica, and other micronutrients. These microscopic organisms are common in coastal areas.  They proliferate through cell division.

A natural progression occurs in many water bodies, from diatoms, to green algae to yellow/brown to blue-green, with time and temperature.  The environment is important.  Southern waters are characterized as being slow moving, and warm.  This encourages cyanobacteria – or blue green algae.  The introduction of nutrients is particularly difficult as it accelerates the formation of the blue green algae. Blue-green algae creates the bright green color, but is actually an end-of-progression organism.

If cells are present in the water mass in large numbers an algal bloom occurs.  An algal bloom is simply a rapid increase in the population of algae in an aquatic system. Blooms may occur in freshwater as well as marine environments. Colors observed are green, bright green, brown, yellowish-brown, or red, although typically only one or a few phytoplankton species are involved and some blooms may be recognized by discoloration of the water resulting from the high density of pigmented cells.

So the desire for development created the idea to drain the swamp, which led to exposure of dark, productive soil that led to farming, which lead to fertilizers, which led to too much water, and water pollution leading to algae.  A nice, predictable progression created by people.  So what is the solution?

The average is 4% of visible infrastructure is in poor condition.  Actually 4-6% depending on the municipality.  And this was visible infrastructure, not buried, but there is not particular reason to believe the below ground infrastructure is somehow far worse off.  Or better.   That 4-6% is infrastructure that needs to be fixed immediately, which means that as system  deteriorate, there is catch –up to do.  The good news is many of the visible problems were broken meter boxes, damaged valve boxes, broken curbs and broken cleanouts- minor appearing issues, but ones that likely require more ongoing maintenance that a water main.  And the appearance may be somewhat symptomatic – people perceive that the system is rundown, unreliable or poorly maintained when they see these problems.  It raises a “Tipping Point” type discussion.  “Tipping Points” Is a book written by Malcolm Gladwell that I read last year (great book – my wife found it in a book exchange for free in Estes Park last summer).  It was along a similar vein of thought as the Freakanomics books – the consequences of certain situations may be less clear than one thinks.  The Tipping point that is most relevant is crime in New York in the early 1990s after Bernard Goetz shot several assailants in the subway.  The problem was significant and the subways were thought to be among the higher risk areas.  The new police chief and Mayor decided that rather that ignore the petty crimes (like many large cities do), they would pursue those vigorously.  So fare hopping on the train and the like were challenged immediately.  They decided that no graffiti would be visible on the subways and cleaned cars every night to insure this remained the case.  Cars with graffiti were immediately removed from service.  New subway cars were ordered.  Pride and public confidence improved.  Crime dropped.  The impact of their efforts was that people recognized that criminal behavior would not be tolerated and fairly quickly criminal activity decreased.  It was a big success story, but the underlying reasons were less discussed, but easily transferrable to our infrastructure.  If we have broken valve boxes, meters, cleanouts, storm drains etc., the same perceptions of a rundown community rise.  Rundown communities lead to a loss of public confidence and trust and pride.   And none of those help our mission or our efforts to increase infrastructure spending.  4% might not look like much, but it can drastically change the perception of the community.  So let’s start to fix those easy things; and document that we did in our asset management programs.
