Our office is very concerned about these increasing concentrations of C8, particularly since almost all are above the recently calculated safe drinking water limit of 150 Mg/I.
Our office has three purposes to this letter. First, can your office give any explanation for these increasing concentrations? Second, can anything be done to get these concentrations down, or can a remediation system be put in place to reduce these concentrations?
If you have any questions, please do not hesitate to contact me at 304-558 2108, Our teletypewriter number is 304-558-2751.
