HEALTH CONSULTATION

SEVEN POINTS SANITATION SITE
MABANK, KAUFMAN COUNTY, TEXAS


CONCLUSIONS

  1. The lead in the ash pile at the Hunter residence could present a public health hazard to children; however, under most normal exposure scenarios, lead confined to a small area would not be expected to present a public health hazard unless children frequently played in that area.

  2. Chronic ingestion of water from the drinking water well on the Penix residence or from the drinking water well 1,000 feet south of the site entrance (background sample) in the EPA Site Investigation could result in lead exposure doses that exceed blood lead levels recommended by the CDC. Follow-up sampling by the TNRCC did not find lead in these water wells.

  3. Although data were not provided, we have been informed that the containers of sludge found near the south pond and the surrounding soil in the EPA Site Investigation were found to be extremely caustic or acidic. This represents a physical/chemical health hazard.

  4. Antimony and manganese slightly exceeded their HAC values in soil and iron exceeded a secondary MCL by a very small margin in a residential well. These contaminants do not represent a public health threat and do not warrant further consideration.

RECOMMENDATIONS

  1. Residents on site should be told of the lead levels near the ash pile on the Hunter residence and should be advised to avoid this area.

  2. Since the EPA sampling detected lead in water from two wells and follow-up sampling by the TNRCC did not detect lead in water from these same wells, water from these wells should be re-sampled.

  3. Any corrosive containers on the site should be removed and residents should be advised to avoid contact with the contaminated soils.
