This Problem may occur to us too

I read this aticle yesterday... DDT and PCB already known as major pollutant last 20 years ago and listed as banned material sience. Those chemical have special stability criteria which can be accumulating effact in our body if consumed. In certain concentration can cause cancer or other complication.

DDT usually used in pasticide and soap although the used already banned but study did also found those substance in recent product which been introduce in line of disposing the existing material. Our government policies to promote agriculture as main industry might be resulted this pollution if we are not pay any attention on the product imported from elseway.

Aku tidak membantah pembanggunan tetapi kita perlu ada polisi yang terang dan jelas berkaitan pengawalan ini. Bahan ini tidak akan hilang atau musnah didalm sistem kerana kestabilannya jadi tiada jalan lain untuk kita.... kita mesti menghalangnya dari memasuki kawasan kita.

DDT deposit off Southern California will be capped

LOS ANGELES – Clean sand and silt will be used to cover a vast deposit of the pesticide DDT and toxic compound PCB on the ocean floor off Southern California, the U.S. Environmental Protection Agency said Monday.

The $50 million plan will target a Superfund site lurking in the waters off the scenic Palos Verdes Peninsula in order to reduce concentrations of the chemicals in fish in that area.

About 110 tons of DDT from a manufacturer and 10 tons of PCBs from industrial operations flowed for years through the Los Angeles County sewer system into the ocean and accumulated in a nine-mile-long swath. Now, an existing thin layer of silt over the contaminants is showing signs of erosion.

Keith Takata, the EPA's Superfund director for the region, said the cap will be placed over the most contaminated sediment on what's known as the Palos Verdes Shelf.

The government will also continue programs aimed at educating the public to not eat contaminated fish.

EPA project manager Carmen White said the actual capping won't happen until 2012, after the best method for placing the sand is determined. The new material can't simply be dropped from the surface because that would stir up the contaminated sediment and spread it. Rather, it must be released close to the bottom, White said.

White said 800,000 cubic yards of clean sand are available from a Los Angeles harbor deepening project and sand could also be transferred from uncontaminated areas of the shelf.
