The Bonzi Sanitation Landfill faces a new round of environmental protection orders because it failed to monitor a polluted groundwater plume that approached a drinking water well last year.
Officials from the California Regional Water Quality Control Board said Bonzi has begun to comply with the order, which requires it to track the plume and provide an alternate source of drinking water if it pollutes the well.
The water board adopted two new enforcement orders to compel the landfill to pay more attention to the polluted plume this spring. The Bonzi landfill has struggled with pollution for years.
The water board ordered it to pay $450,000 in penalties in 2006, and to monitor and clean up tainted groundwater.
