Oilfield wastewater disposal site closure Question 2

mtebbe

percolation and evaporation pond operation accepting oilfield produced water, which is a highly saline byproduct of local oil production that contains small concentrations of cancer-causing chemicals.

The wastewater allegedly contained arsenic, benzene, ethylbenzene, naphthalene, radionuclides and toluene.Clean Water Fund and AIR alleged the practice has created an underground plume that has spread more than two miles since monitoring wells were established in the area in 2004, and that the contamination may eventually reach Buttonwillow's drinking water supply.

Oilfield wastewater disposal site closure Question 5

Valley Water Management Company (owner) & Sentinel Peak Resources (oil producer): fined $645,000

Clean Water Fund & Association of Irritated Residents: sued using Prop 65 (Safe Drinking Water and Toxic Enforcement Act of 1986) to shut down pond

other oil companies: inject wastewater deep underground in or near reservoirs where it originated

Central Valley Regional Water Quality Control Board: forced closure of pond out of concern that underground plume will reach Kern River and Bakersfield's drinking water

LA sewage sludge court fight Question 2

mtebbe

11 wastewater treatment plants in LA County produce half a million tons of treated sewage sludge from human waste per year. Sludge is sent to a lnadfill in Kern County, the Westlake Facility, and some to Arizona

water pollution from sewage sludge

air pollution from sewage sludge and from trucks hauling the sludge to the farm - 55 trucks per day/20,000 per year at full capacity

LA sewage sludge court fight Question 4

mtebbe

LA County: "It's an important investment in long-term, reliable infrastructure that is critical to our ability to provide vital wastewater treatment services"

Westlake Farms: receiving less than they bargained for

Local farmers: it's a way to dispose of green waste (like wood chips)

Environmental groups and residents: concerned about air and water pollution, sued the project but settled after LA agreed to use clean-fuel trucks to haul waste. “It seemed like another deal where the Central Valley gets shafted by Southern California,” she said. “We send them good water to drink, and they send us back their poo. … I can’t say I’ll be really upset if they’re not operating at 100%.”

LA sewage sludge court fight Question 5

mtebbe

LA County: bought 14,500 acres of a farm for $27.4 million, used 2,500 acres to construct the $130 million composting plant, leased the remaining land back to the farm. The plant processes less than a 10th of what it was supposed to process, providing the farm with much less fertilizer than they expected.

Westlake Farms: sold the land to LA County, sued to have the sale undone after the plant produced much less fertilizer than expecte

Kings County and other nearby counties: banned application of biosolids (human waste) directly onto land, forcing LA to build a composting plant

Biomass energy failing Question 4

mtebbe

Biomass energy plants: see themselves as a cost-effective solution for farmers who need to get rid of dead trees and other woody waste that pose wildfire risks without openly burning them; they also produce energy

Utilities companies: looking for the "least-cost, best-fit" source of energy, don't care where it comes from just that it's reasonably priced

Farmers: need cheap ways to dispose of waste
