If you are a wastewater utility, and you create a high quality effluent product that can be used for industrial purposes, irrigation or aquifer recharge, who “owns” the water?  If the utility is sending to a golf course pond for discharge, the answer seems obvious – the golf course owns it.  Not so fast.

Now let’s day you are recharging and aquifer.  You pump it into the ground with the intention of recharging the aquifer to benefit your wellfield.   Or you pump it into an aquifer storage and recovery system with the intent of recovering it when you need it.  Quick impression is that you should own it, but what about the people that sink walls along the way?  Or have existing wells in the vicinity that can tap your injected water?  Can you keep people from pumping it out?  Not as clear.

What about discharge to a stream with the idea of capturing it downstream in an intake system for your water system?  Much less clear.  The ecosystem, farmers, irrigation users, etc. along the stream could use the increased flows.  Can you keep them out?  Very unclear.

Now assume you are a water rights state and there are people who have rights to the aquifer or stream that are more senior to yours.  Can you clip their claim to the water by claiming the water is yours?  Really not clear and the subject of ongoing regulatory discussion and legal proceedings.

There are no clear answers to these questions but they have major long-term impacts of water resource planning in much of the US.  The problem is the rules assume facts not in evidence at the time of the permit (or claim).  Conditions can change – permits and rules may not (or have not).  Maybe the water regulations and that the changed condition should perhaps obviate the prior claim?  A very tough legal issue and one bound to make a bunch of people unhappy.  The concept of reclaiming water from waste was not a consideration in the past, so clearly the rules that cover reclaimed water need to be revised.  I can’t wait to see the results.

Fires and Climate Change

The Union of Concerned Scientists reviewed recent wildfires in the west. One of the concerns they raised was that increased forest fires are both a climate change and a man-induced issue.  Wildfires on federal land has increased 75% on federally owned land.  Fire impacted areas are larger and impact more development which encroaches on those federal holdings.  We spend over $1 billion in fire fighting on federal lands each year.  But why?

Because many of the forest are in mountainous areas, fire season starts earlier in year with less mountain snowfall.  And that is  most years as snowfall accumulation decrease.  Temperatures are warmer, earlier with shortens the snow season.   Water runs off faster.  Of course the fact that we altered management philosophies to prevent all forest fires didn’t help because some burning is natural each year. As a result there is a huge reserve of unburned land out west.  The beetles did not help either as they left millions of acres of dead trees on mountain sides from Canada to New Mexico. Beetle infestation is clearly climate change driven.

The solutions are more difficult.  Building up next to federal land needs to be restricted.  Regulations in dealing with trees, bushes and underbrush in fire prone areas need to be enacted and enforced. Early spring fires set as control burns need to happen more frequently. But these are all local responses to a global climate problem.  That response is currently lacking.  These are leadership issues.

From a utility perspective, this issue may be significant.  We like those high, clean mountain streams.  But after a forest fire, those streams are often warmer and less clean.  The soot, ash and runoff from now barren land can create significant impacts on water plant, create major treatment alterations, increase costs, and risk contamination.  A friend some years ago suggested that utilities were instruments of social change.  The fact that we have treated water and sewer creates social change.  We need to protect water supplies and therefore we should be a part of the conversation on land use.  That requires some leadership.

 

Remembering Heros

Every winter, the Collings Foundation flies into southeast Florida with a restored B-17 Flying Fortress and a B-24 Liberator. These vintage airplanes are a major part of why the Allies won World War 2 and it is fantastic that people have an opportunity to see a flying 70 year old airplane.  I took a ride on this B17 several years back.  My Dad was on one for 25 missions in 1943.  I couldn’t get him on with me.  He figured that was enough even when I offered to pay the $350 for the 45 minute ride (well worth it!!).  Even reminding him that there would be no flak and no bullets streaming through the plane was not enough. But when I got on, there were 11 more guys my Dad’s age taking yet another ride in the B17.  Interesting if you flew in a B17, that’s what you wanted to ride – and I am sure vice versa with the B24.  The stories were great.  My Dad’s tour of the plane (on the ground) was enlightening.  Too bad these guys are leaving us.  I encouraged my students to take a look when the planes were next to campus.  I took a few hours before class to wander about.  Another year I will jump back on the B17.  If you get the opportunity, I encourage you all to do the same.

In the meantime, the question that we need to think about as we remember these men and women is where are these folks today?  Millions of men and women worked hard, fought and many died trying to benefit society, not themselves.  They were looking out for the world, their friends and families.  They were looking out for a way of life for the future.  Leadership requires a prospective view, a vision for tomorrow and a willingness to sacrifice and do what is needed to achieve that vision with the intent of providing betterment for all.  So as we look forward in 2015, this seems to be an obvious issue to explore.  I look forward to your views.

It’s February already!  Where has the year gone?  My apologies for a January without posts.  Things have been busy here and well, blogging got put on the back burner for me with the new semester starting and a new class to design.  But interesting kernels from January:

The World is Trying to Kill You – Dr. Neil deGrasse Tyson

If you have a 20% failure rate, does that make a speculative technology a waste of time?  Conversely if your success is 20% is it successful?   I think no and no.

Have you noticed that February is the month we have been getting the worst winter weather in the Midwest and northeast? Not December or January?  I used to shovel snow all January and wait for the February respite.

Killer whales are now a protected species.  What does that say about the killer whales as SeaWorld?

There is a honeybee crisis.  No really, a real one.  Not the Jerry Seinfeld movie.  But the lesson is the same.  No bees, no food.  We need to figure out how we are killing them.  No doubt when we find out it will come back on pesticides, herbicides, monocultures, some combination of the above.  Not a good thing for farming.

The bison are under attack again in Montana.  Maybe Mother Nature is trying to tell us something – buffalo want to roam to their winter grazing fields.   And no brucelliosis, the issue rancher bring up as to why the bison are bad, has still NEVER been transmitted from bison to cattle.  Bison are way better on the land since there hooves are much large and they do not compact the ground as much.  But they are not as stupid as cattle.  They know they can walk thought a barbed wire fence.  They are bison afterall!

A Utah rancher shot and killed Echo, the female wolf that made it to the Grand Canyon last summer and became a national story.  He thought she was a coyote.  Um, I think wolves are a little bit bigger than coyotes.  We have a man with a gun who can’t tell what he’s shooting.  What could possibly go wrong with that?

Then there is the bear hunt in Florida because people move closer to the woods and cannot figure out how to secure their garbage of close their garage doors.  Bears get killed.  People…..

Miami Beach installed $40 million dollars in pumps last summer, with an expected $300 million for.  The nearshore nutrient concentrations increased dramatically (a factor of six), which could adversely impact beach quality, fishing and reefs.  Unintended consequences, but an issue was brought up as a potential concern.

Education Problem of our own Making?

Orange County, FL has become the second school district I know of that has decide that giving students a zero on a assignment causes the kids to lose hope of passing so they just quit.  To address this problem, the worst grade you can give them is a 50 instead of a zero.  That way they can recover from one missed assignment.  Huh?!?!  No, you read this right.  The school superintendent was quoted in the SunSentinel as saying that only 43 percent of the students who received a 50 actually recovered to pass the class with a D.  I have several questions.  First, how does this policy teach these kids any responsibility?  For the kids that do their work, how is that fair?  What message does this policy send to the kids?  Be a lazy dumbass and do nothing and you can still pass?  That reinforces the concept of entitlement which we all agree is a problem in society that we need to overcome.  Finally, if one missed assignment causes the kids to fail, why are there not more assignments so missing one is not fatal?  That is what happens with my students (who still get a zero for not doing an assignment).

It would seem that such a policy is not based on an educational goal but more like a political one to improve school perception.  That is as bad an idea as having kids beg for money for uniforms and class trips etc.  Kids do not sell anything they just beg for money.  So are we teaching them that begging and panhandling is an acceptable career?  Seriously what impression does that provide to these young minds?  How does either experience prepare kids for the real world where doing nothing gets you fired, not rewarded, and begging for money vs actually work is also not rewarded.

Once upon a time, education was the purview of the wealthy.  American businesses argued that a basic education was needed to train a workforce for industrial jobs.    The American public education system was created with this in mind- to train the next generation of workers.  With education came great social and economic advancement.  We clearly are deviating from that goal.  Students need a good foundation in math, writing and reading (in English!), civics and science so they understand social responsibility, can communicate, understand how things work the world and can solve complex problems.  They do not need pseudo-science or politicized science, but real science.  Business understands this.  But where is the business community on job training in schools?  It would seem the business community has abdicated their responsibility to local districts who are trying to meet political goals, not economic goals.  Why are we not using all the extensive testing to figure out the strengths of students and encourage them to play to those strengths? Not every kid can go to college, or should, but that does not mean they cannot achieve or be successful.  They may need different training to hone their strengths.

Back in the day my Dad told me that as the education system was developed in his hometown of Detroit, students were given aptitude tests.  I was also.  The kids were divided up based on skills and aptitude.  Students were even sent to different schools as they got older that tailored programs to their interests and skills set.  Kids that the schools system felt had the aptitude to succeed in college had different courses than students that were less academically included but perhaps more mechanical, more artisan, more labor, clerical, etc.  Different kids go training to help them succeed with their skills.  Less academic did not mean less inclined to succeed or be successful. just differently.  And they had a better chance to be successful.  We seem to miss that today.

Today we have parents insisting that everyone be treated the same, and that no kid gets left behind.  But putting kids with different aptitudes, maturity, and academic inclinations in one class is destined to either fail for all, or fail for everyone but the average.  Such a protocol begets policies like Orange (and Broward) County that direct teachers to adjust grades so “Little Johnny” doesn’t feel bad.  Extensive college prep testing and disconnected learning discourage the less academic kids, leading to dropping out, or other behaviors.  Such policies and expectations by parent and political leaders are not helpful for building an educated society.  Instead we need to search further into the root causes.  Are there too few assignments?  Are they too disconnected for students to appreciate?  Should we sort out strengths and treat different students differently to discourage disinterest?  How do we assess their strengths and design programs to help students succeed.   And who takes responsibility for these kids?  And perhaps we should revisit some of the lessons learned from the early years of the industrial development (1930s) to figure out what they did well, and see how policies today frustrate those goals.  Maybe the way forward is rooted in the past.

I hope you and your have a very happy holiday season – whatever holidays you may be celebrating.  And I hope that 2014 has been a good year for you and that 2015 will be happier still.   The end of the year is a good time to reflect on all the positive things in our lives.  For most of us we have food, shelter, a decent job, transportation and friends.  We have clean water, sewer systems to remove waste, trash pickup and decent highways (Thank you civil engineers!).. We are relatively safe and have access to good medical care. And we have friends and family that we care about and want to share with.  ‘Tis the season to be jolly, happy, merry and all those other words.  Happy Holidays to all!

How did southeast Florida not end up on the list of US cities with the worst drivers?  This seems like an annual rite for us and if you have lived down here you know why.  Things have not improved, so what does that say for Worcester, MA, Boston, Washington DC and Springfield MA that they took the top 4 spots?  Sometimes it is good not to be number 1!  LOL

A group called Idaho for Wildlife requested and got approval for a hunting contest open to children on public lands whereby they will attempt to be the child who kills the most wolves.  What could possibly go wrong here?  First the only ones with guns are children.  Those children are running around public lands trying to shoot the most wolves.  We assume there are people with them, but since they are trying to kill the most wolves, I would expect more shooting than normal.  So what if the critter is a coyote or fox or missing German shepard or guy working on a water system?  And aren’t we trying to bring wolves back because we have figured out that eliminating them vastly impacts the ecosystem negatively.  Maybe if Idaho for Wildlife (interesting misconcepted title) thinks there are too many wolves, wouldn’t trapping a few and releasing them in a place that maybe needs some would be a better idea?
