The following are my general comments:
1. Based on the
available data, I do not see any specific problems or concerns.
2. It would have
been advisable to test for more of the regulated and unregulated volatile
organics and MTBE. They only tested for
BTEX (Bold).
3. It would have
been good if the arsenic was tested to a lower detection limit.
4. The letter R-
means it was a recommended standard – not regulated.
5. Ethylene
glycol – the method did not have a detection limit that is below the lowest
standard for a state in the United
States .
There is no Federal Drinking Water Standard. The same comment applies to
Cobalt.
6. Thallium – the
detection limit was not below the limit for the Safe Drinking Water Act.
Recommend
retesting.
