Violates Board Order R6V-2000-0013 MRP II.C.2. Ongoing EMP. Inorganic concentrations above the MCL are within historical ranges, COC concentration-trends in compliance wells are similar to trends in the background well, and do not indicate a new or expanding release from the landfill. Therefore, no additional corrective measures are warranted or recommended, and ongoing source control measures, site maintenance and monitoring, and routine groundwater and soil-pore gas monitoring should continue.

*Click the "(+/-) Violation Description" link to expand and contract the violation description.
*As of 5/20/2010, the Water Board's Enforcement Policy requires that all violations be classified as 1, 2 or 3, with class 1 being the highest. Prior to this, violations were simply classified as Yes or No. If a 123 classification has been assigned to a violation that occurred before this date, that classification data will be displayed instead of the Yes/No data.
