EPA review finds 'problem' with toxic-gas model

By Mark Obmascik 
Denver Post Staff Writer
Thursday, February 07, 2002 - Relying on U.S. Environmental Protection
Agency advice, three states adopted toxic-gas pollution standards so lenient
that they often fail to protect public health, an EPA scientist has found.

All three states - Connecticut, Massachusetts and Michigan - based toxic-gas
regulations on a controversial EPA computer model. A Denver Post
investigation last month found that the model often underestimates the
health threat of toxic gas leaking into homes from underground pollution
plumes. 

{SNIP}

In a new review made public last month, an EPA hydrogeologist found that
Michigan's model-based regulations failed to detect unsafe levels of toxic
gas in homes 86 percent of the time. Connecticut's failure rate was 75
percent, and Massachusetts' was 36 percent.
