CTEC Receives No Response to Request for Exposure Data
On October 15, 2012, CTEC sent the following letter to the Butte-Silver Bow Health Department and numerous EPA officials requesting public test data on arsenic and lead exposure in the Butte area, with the intention of using that data to better comment on, advise on, and provide public information about the ongoing development of a public health study for Butte. To date (November 30, 2012), CTEC has received no formal response.

Butte-Silver Bow Health Department
25 West Front Street
Butte, MT 59701
Dear Ms. Hocking:
CTEC would like to access existing arsenic and lead exposure test data for Butte/Silver Bow. CTEC is interested in proactively providing input/comments into the draft work plan for the Public Health Study. The health monitoring data is important to CTEC and the public’s ability to understand what current public health is and to provide proactive comments on how the Public Health Study may be performed. In order to participate in the Health Study process, CTEC needs access to this public data. The data that we have seen so far is limited to the Five Year Review which provided some statistics for annual number of lead tests greater than 10 ug/L and did not report arsenic exposure data.
I understand that there are privacy issues with the data. Can you let us know when the data can be provided in a form that scrubs anything that would cause a privacy concern? It may also be possible for CTEC to work with statistics if it is possible to request the specific statistics needed and have those statistics provided prior to CTEC commenting on the draft work plan.
Specifically, CTEC would like blood lead testing data which give the following information.
If all individual test results are to be provided:
1. Date or year of test
2. Blood lead level.
3. Whether the test is a repeat or 1sttime for the individual.
If statistics and not individual results are to be provided:
1. Year of tests.
2. 5th, 25th, 50th, 75th, 95th percentile and mean blood lead level for all tests that year.
3. 5th, 25th, 50th, 75th, 95th percentile and mean blood lead level for all 1sttime tests for individuals that year.
4. 5th, 25th, 50th, 75th, 95th percentile and mean blood lead level for all repeat tests for individuals that year.
We would also request any and all data pertaining to arsenic blood levels.
