PUBLIC HEALTH ASSESSMENT

MURRAY SMELTER
MURRAY, SALT LAKE COUNTY, UTAH


CONCLUSIONS

ATSDR considers the proposed Murray Smelter NPL Site to be no apparent public health hazard. This is based on finding no elevated blood lead or urine arsenic levels in an investigation ofchildren and adults from Grandview and Doc and Dell Mobile Home Park. These results indicatethat health effects due to arsenic, cadmium, and lead are unlikely due to limited exposure to thesemetals. This conclusion is also based on a toxicological evaluation of worker exposure situationswhich indicated that exposure levels were too low to result in health effects. However, ifexposure circumstances changed so that the amount of exposure increased significantly, healtheffects would be possible. Therefore, remediation of contaminated soil should be done based onthe potential for health effects as indicated by the soil levels of these metals.

There is limited potential for human exposure to site-related contaminants in groundwater, fishand sediments in Little Cottonwood Creek, and vegetables grown in area soils.

Surface water is eliminated as an exposure pathway because surface water near the site is not usedas drinking water and skin absorption of dissolved metals from surface water is unlikely to besignificant.

PUBLIC HEALTH ACTIONS

A major purpose of a public health assessment is the identification of the actions needed toprotect public health, evaluate whether exposure is occurring or could occur, or identify whetherthere are site-related health effects. We have identified the following public health actions.

Completed Public Health Actions

In October 1995, the Salt Lake City/County Health Department, ASARCO, and ATSDR testedchildren and adults in the Grandview and Doc and Dell's mobile home parks for lead in blood andarsenic in urine.

In 1995, ASARCO removed the contaminated material from the swing set area and other adjacentareas with surface slag and potential smelter-derived materials in the Grandview Mobile HomePark.

ASARCO monitored groundwater on site to determine water quality. ATSDR recommends thatthe source of on-site arsenic contamination be identified and removed if feasible.

Ongoing Public Health Actions

EPA/ASARCO plans to evaluate whether further soil removals at Grandview Mobile Home Parkshould occur.

Recommendation to Area Residents

We recommend that people consuming homegrown produce from gardens in contaminated areas(Figures 3 and 4) use 2 feet of clean fill for their gardens.

Public Health Comment

The public health assessment was available for public review and comment in the Murray libraryfrom October 10 to November 29, 1996. The public comment period was announced in localnewspapers. In addition, the public health assessment was sent to several individuals, federal,state, and local agencies, and ASARCO. Comments were received only from a consultant forASARCO, PTI Environmental Services. Those comments and our responses are summarized inAppendix 4 beginning on page 47.
