Preliminary:Water Quality

Postby Jim_R » May 5th, 2011, 12:35 pm

Water Quality is probably going to replace Ecology in the 2012 season.This is the prelimanary thread to keep it somewhat organized
Who's done it, and what does the event focus on?
-The path of the Administrator is beset on all sides by the inequities of the selfish and the tyranny of evil men.

-Nothing\'s gonna get deleted. We\'re gonna be like three little Fonzies here. And what\'s Fonzie like? Come on, what\'s Fonzie like?
-Cool?
-Correctamundo. And that\'s what we\'re gonna be. We\'re gonna be cool. Now, I\'m gonna count to three, and when I count three, you let go of your mouse, and back away from the keyboard. But when you do it, you do it cool. Ready? One... two... three.

I looked at a couple Water Quality Tests on the tufts website and they look pretty interesting. There is some invertebrate ID, and estuarine ecology. There's also a focus on the invertebrates as bioindicators. All in all, I think it'll be interesting and be a good replacement for Ecology. I'm looking forward to hopefully doing it next year. Of course, I also do Ocean Sciences Bowl, so I have the biased opinion that anything dealing with water is interesting.

Don't forget the building of a Salinometer. Do we actually have to test it there and find out a concentration given to us?

Sorry for the double post, but I found these old rules
(http://sps.k12.mo.us/pipkin/SODivb/wate ... Qualty.pdf)
and how to build the clay model type of the salinometer (http://sps.k12.mo.us/pipkin/SODivb/wate ... ometer.pdf)

I've done it before, though it was only once at Invitationals. Still one of my favorite events ever though.

A major part is being able to ID insect larvae. These are indicator species, and they can tell you how clean or polluted a body of water is by their presence or absence; for example, dragonflies can only survive in very clean water, while blood midges can survive in basically anything. The list isn't that big.

Also know the invasive species, such as purple loosestrife (plant) and the zebra mussel, and know what an invasive species is and what effects they can have on the native population.

Know the different nutrients and how useful they are, and how to test for them (if you have to test, they should provide a chemical test for you, just follow the directions and match the color to the one on the box). These nutrients include nitrates, phosphates, dissolved oxygen, biological oxygen demand (not quite a nutrient, but it's sort of related to DO, or dissolved oxygen), and "water hardness" (calcium and magnesium). There's probably a bit more. Also, tests for coliform bacteria; present of that is bad, it means that there's fecal matter.

There's also a part about water remediation; know how water passes through waste treatment plants and the different stages of remediation.

The salinometer is a minor part, and it shouldn't be too difficult to build.

That's about all I remember, hope this helps. I'll see if I can dig up any of the practice events I did way back when.

So this is basically AP Environmental Science + looking at insects and invasive species? Cool! In my opinion, this event sounds kick-butterfly.

You know, I did this in eighth grade, in my earth science class, and I liked it. I'm actually pretty excited for this.

Is ID guaranteed to be involved in the rules?

I'm not sure as I haven't seen any rules sheets for this event next year, but if it's the same as it was before (looking back at old tests on the tufts website), then yes.

The ID will be limited to macroinvertebrates and invasive species, if I remember correctly.
Question: Not sure if anyone remembers, but when this was run as an event, was the salinometer used like awesome aquifer where you just explain it, or do they give you an unknown liquid and ask for the concentration?
