Oil company foils government inspectors with high-tech gadgets (coffee filters)

January 10, 2013

An oil company admitted Thursday that coffee filters were used to doctor water samples and cover up the fact that it was dumping oil and grease into the Gulf of Mexico on its platform 175 miles south of New Orleans. …

Just to be clear, the reporting process goes like this.
1. Company takes water sample.
2. Company sends water sample to government.
3. Government looks at submitted water sample and says OK.

And in order to get that OK, the company need only add step 1a: Pass them through a semiporous piece of paper. Got it.
