Waste watch

　　A newspaper reporter is interviewing someone from “waste watch” in New York.

(J=Journalist      P=Person)

　　J: What exactly is your job?

　　P: Our job is to make sure that the laws about pollution and waste are not broken. There are over thirty different pollution laws in the state of New York.

　　J: when was the “Waste Watch”section started?

　　P:In 1981.There had been a lot of reports of pollution. So the government told the police force to start up a special section.
J:How bad was the situation?

　　P: It was pretty bad. Some firms were pouring waste straight from their factories into the rivers. Some were pouring liquid waste onto dry land inside the factory. Others were paying truck companies to take the waste out o town.

　　J:So what do you do now?

　　P: We look out for companies driving waste out of town. They need permission to do this. And we check on companies whenever we get reports.

　　J: Can you give an example?

　　P: Yes. We had an idea one company was breaking the law. Once a week a truck used to call at the company’s factory. It never delivered anything, but we thought it was taking away waste. .So we followed the truck..We used an ordinary car,not a police car, of course. At four o’clock the next morning, the truck drove to the port and started to pump the liquid into the sea. We stopped the driver, turned off the pump and took him to the police station.We had everything we needed, a bottle of the liquid and a photograph of the liquid being pumped into the sea.
