Next Round of Experiments

by megan |

It has been decided that the next round of experiments will take place at the first well pad off the main road, Sunray 1.

The experiment will take place in two parts, one will be placed out for one week, one will be placed out for one month.

Each test site will have two container, one labeled in blue, and one in black. The containers labeled in black will be left out for one month, the containers labeled in blue will be left out for only one week.

The containers will be placed in a compass rose position around the well.

The containers will be placed in rings radiating out from the well, in 50’ increments, one set of 8 containers at 50’, one at 100’ and one at 150’

This site will test a total of 48 containers; the containers will all be oriented vertically.

Kit.

The kit I sent out for this experiment contains the following pieces:

3 black photo bags, labeled 1, 2 & 3 2 measuring strings, 50' & 25' 4 control containers

Instructions.

The contents of the bag labeled 1, is meant to be placed 50' away from the well pad. A 50' string is included as a measuring device. Each bag contains 8 pairs of labeled containers, the photo paper already inside, stake attached, ready to go. Each pair should be placed in the compass rose position, which is on their label. (One of the pair is labeled in blue , to be collected after one week and one is labeled in black to be collected after one month)

Bag 2 The measurements for placement of the containers in bag 2 should be taken from the containers from bag one.

Bag 3 The measurements for placement of the containers in bag 3 should be taken from the bag two.

Controls:

Control 1 Stick in ground near container from bag one, the blue will be collected after one week, the black after one month. Container is sealed closed, do not open!

Control 2 The photo paper is meant to be removed from these containers and taped to something on site (a rock, fence) near containers from bag one. This control is meant to see the difference in exposure with and without the container.

Hey Megan - have you been in touch with the Pioneer Valley open science folks, like Don Blair? They're working on an electronic sensor which it would be interesting to use alongside the strips. Just want to make sure you're aware of what they're up to; i'm happy to make an introduction.

This is comment on the next round of testing at the SunRay #1 site. I see a problem with the placement of canisters in the proposed concentric circle configuration. Simply put, the canisters will not be there in one week if left in the open areas that constitute most of the 50’ radius; placement must be in some minimal cover. It appears that this can be done in the E/NE/N/ sectors; and in the remaining sectors, Circle 1 will have to be moved back and then begin the 50’ incremental spacing. In addition to the articles in the pictures, I will take a compass, a GPS unit, and H2S detector, and a current organ donor card.


Hi Josh -- do you think they'll be stolen, or just kicked around, or what? Also, what kind of H2S detector do you already have?

I worry about exposure too; I know it sounds silly but i wonder if a sensor could be sent around on an RC car or something, so nobody has to go very near the site.


In the call the other day on the experimental design we discussed the need to tape over the canisters at the end of the experiment to prevent air contamination. In sending out the experiment we are working under the assumption that the bag does that, so at least for this first experiment that might be an unnecessary step. I just mention because it is just another thing that will take time in the field.


It would be cool to leave a stationary sensor that maps H2S levels over lets say a week or month or something, then maybe we could find a time when the levels are predictable low to go out there. Other idea for you Josh, just get an intern, and send them out there.


Hi Warren, thanks, I have not been in touch with them, but Sara mentioned the work they are doing I believe. Is he at Amherst? I don't understand the electronic stuff they are talking about, but I would be interested in working on the graphic output of those senors, if that is something they are interested in.


We talked about starting the center point of the concentric circles between the well and the condensate tank (approximately South 50tf spot).

Then having a ring at there starting at 100ft, then 150 ft and 200 ft.

So we need to redraw the diagram.


We need to send three more light safe bags for putting the samples in when they are picked up.


discussed bringing someone else from the citizen alliance along.


possible timeline: Monday/Tuesday next week 8th and 9th, put samples out.

Pick Up round 1: 15th and 16th. October Pick Up round 2: 5 th and 6th November


Also can Public Lab plan a training for H2S field work? Do a webinar on it?


Mark new center point with gps.


Monitor to take on the day:

Josh had rented a Gas Badge Plus for $20 a day from Safety Alliance in Farmington, (505)-325-7233

I have included this link to information on the Gas Badge Plus http://www.durawear.com/index.cfm/a/catalog.prodShow/vid/485/catid/145
