Groundwater	Pentachlorophenol Antimony Arsenic Lead Manganese Selenium Vanadium Zinc	Infiltration from Shot Piles and Evaporation Lagoon	Groundwater	None Identified	None Identified	None Identified	Future ?	We were not able to identify any evidence of past or current human exposure to contaminated groundwater. Groundwater considered to present no public health hazard at this time.

Criteria:

Evidence exists that exposures have occurred, are occurring, or are likely to occur in the future; and the estimated exposures are to a substance or substances at concentrations in the environment that, upon short-term exposures (less than 1 year), can cause adverse health effects to any segment of the receptor population. The adverse health effect can be the result of either carcinogenic or noncarcinogenic toxicity from a chemical exposure. For a noncarcinogenic toxic effect, the exposure exceeds an acute or intermediate minimal risk level (MRL) established in the ATSDR Toxicological Profiles or other comparable value; and /or community-specific health outcome data indicate that the site has had an adverse impact on human health that requires rapid intervention; and /or physical hazards at the site pose an imminent risk of physical injury.

CATEGORY B.
PUBLIC HEALTH HAZARD

This category is used for sites that posea public health hazard as the result oflong-term exposures to hazardoussubstances.

Criteria:

Evidence exists that exposures haveoccurred, are occurring, or are likely tooccur in the future; and the estimatedexposures are to a substance orsubstances at concentrations in theenvironment that, upon long-termexposures (greater than 1 year), cancause adverse health effects to anysegment of the receptor population. Theadverse health effect can be the result ofeither carcinogenic or noncarcinogenictoxicity from a chemical exposure. For anoncarcinogenic toxic effect, theexposure exceeds a chronic MRLestablished in the ATSDRToxicological Profiles or othercomparable value; and/orcommunity-specific health outcomedata indicate that the site has had anadverse impact on human health thatrequires intervention. CATEGORY C.
INDETERMINATE PUBLIC HEALTH HAZARD

This category is used for sites withincomplete information.

Criteria:

The limited available data do not indicatethat humans are being or have been exposedto levels of contamination that would beexpected to cause adverse health effects.However, data or information are notavailable for all environmental media towhich humans may be exposed; and there areinsufficient or no community-specific healthoutcome data to indicate that the site has hadan adverse impact on human health.

CATEGORY D.
NO APPARENT PUBLIC HEALTH HAZARD

This category is used for sites where humanexposure to contaminated media is occurringor has occurred in the past, but the exposure isbelow a level of health hazard.

Criteria:

Exposures do not exceed an ATSDR chronicMRL or other comparable value; and data areavailable for all environmental media to whichhumans are being exposed; and there are nocommunity-specific health outcome data toindicate that the site has had an adverse impacton human health.

CATEGORY E.
NO PUBLIC HEALTH HAZARD

This category is used for sitesthat do not pose a public healthhazard.

Criteria:

There is no evidence of current orpast human exposure tocontaminated media; and futureexposures to contaminated mediaare not likely to occur; and thereare no community-specific healthoutcome data to indicate that thesite has had an adverse impact onhuman health.
