  • A lake in the southeastern United States provides drinking water and recreation. It is also home to a former hazardous waste landfill, currently managed by a trust.
  • Locals became concerned about drinking water contamination and mismanagement of the site. To counter negative public perception and independently assess the site’s operations and management, the state — which provided financial oversight of the trust — turned to Haley & Aldrich.
  • We evaluated the landfill and found that it did not pose a risk to public health or the environment, sharing our results openly with the community and other stakeholders to quell fear and meet all regulatory requirements.
  • We also identified and provided solutions to reduce the generation of leachate — rainwater filtered through the landfill — which saved the trust over $500,000 dollars per year.
