“Little information is available on the health effects from low-level exposures. The small body of available information varies widely.

Note the Carbon Dioxide attracts mosquitos too
The Arc Park site is one in Ft Worth that I have blogged about before. On FB I was laughing at the pictures on Google Earth capturing what looks to be a picnic for the Chesapeake employees and other political stakeholders.
Chesapeake installed four Intevras’ EVRAS system water evaporation units at the Brentwood SWD site in Fort Worth.
Salt Water Disposal Pilot Project October 14, 2008 – Granicus
Originally they had an expensive/failed? (can’t get any info) test pilot program to evaporate produced water using the heat from the compressors…..”without scrubbers” per the salesman of those Everas units. The comment was made I recall was that the scrubbers were available and mandated in California but that they were not being used in Ft Worth…that was one of the first fracking battles I fought…but back to my H2S story here….this is the site that was tested…..FYI the balloon is not a reference to where the sample was taken…

1 ppm found of h2s was near the Chesapeake Campus.
The RRC plays DOWN the health risks from 1-10 ppm for an 8 hr exposure and calls it “safe”……..
B U T contrast that “short term safe ASSurance” from our RRC state frack luving fellows to a concerned DOCTOR of chronic long term low dose exposures ….
Human Health Effects from Exposure to Low-Level Concentrations of Hydrogen Sulfide
“Little information is available on the health effects from low-level exposures. The small body of available information varies widely.
EXPOSURE to high levels of hydrogen sulfide gas is a well-documented and understood hazard. OSHA and NIOSH standards have long recognized this acute risk with appropriate short-term maximum exposure levels for workers. However, long-term, chronic exposure to low levels of hydrogen sulfide is not as well understood.
Current hand-held detection equipment for hydrogen sulfide generally has a detection limit of 1 ppm, which is well above the odor threshold. This detection equipment is good for monitoring acute exposures, an application for which this equipment is generally used and is well suited, as OSHA and NIOSH standards are above this detection limit. However, if chronic toxicity for hydrogen sulfide exposure exists and is below 1 ppm, this equipment is obviously inadequate.”

Got nosebleeds since drilling came in? WE do!
update the Truman has 2.5 ppm H2S per a 5/2/13 sample…this was on their PBR….
