MDL- Minimum Detectable Level (The smallest level that can be detected by test).

MDL 0.048

MCL- Maximum Contaminent Level; In 1974, Congress passed the Safe Drinking Water Act. This law requires EPA to determine safe levels of chemicals in drinking water which do or may cause health problems. These non-enforceable levels, based solely on possible health risks and exposure, are called Maximum Contaminant Level Goals. Based on this MCLG, EPA has set an enforceable standard called a Maximum Contaminant Level. MCLs are set as close to the MCLGs as possible, considering the ability of public water systems to detect and remove contaminants using suitable treatment technologies.

LINDANE MCL 0.2 ug/l

Lindane (gamma isomer of 1,2,3,4,5,6-hexachlorocyclohexane) is an insecticide registered for
commercial and home use. Lindane is the active ingredient in several prescribed shampoos used for the elimination of head lice. Lindane is slightly soluble in water and will volatilize to the atmosphere from soil or water. It is persistent in soils (half-life greater than 100 days), though it does undergo rapid biotransformation under anaerobic conditions. Acute exposure of animals to lindane results in neurological and behavioral effects. The liver and the kidney appear to be the primary target organs for lindane toxicity. Lindane is classified as "B2-C" (i.e., in between the lower half of the "B" category of'probable' and the "C" category of ;possible' carcinogen classifications) based upon evidence that lindane gives rise to malignant liver tumors in two strains of mice, plus supportive evidence of precancerous liver lesions in shorter term studies. Lindane, because of the potential adverse effects and occurrence in drinking water, is regulated.
