  "id": "MLC-T-ENV-015652",
  "term": "Level I Concentrations for the Ground Water Pathway",
  "field": "Environment",
  "definition": "Level I concentrations are established for samples from drinking water wells in which the concentration of a hazardous substance that meets the criteria for an observed release is at or above its specific health - based benchmark. A drinking water well also may be subject to Level I concentrations if multiple hazardous substances that meet the observed release criteria are present below their respective benchmarks, but the I or J index is greater than or equal to one. Benchmarks for the ground water include maximum containment levels (MCLs), nonzero maximum containment level goals pathway (MCLGs), and screening concentrations for cancer and chronic noncancer effects.",
