On , March 4, 2008, Scientists in Oregon partnered with city workers in 96 communities, including Pendleton, Hermiston and Umatilla, to gather waste water samples on one day with the intent to measuring the drug content of waste water. The scientists then tested the samples for evidence of methamphetamine, cocaine and ecstasy, or MDMA. with the result that every one of the 96 cities -- representing 65 percent of Oregon's population -- had a quantifiable level of methamphetamine in its wastewater. The data gathered from municipal wastewater using wastewater sampling equipment is concrete and reveals a detailed snapshot of drug use for that day. Researchers placed cities into ranks based on a drug's "index load" - average milligrams per person per day. These techniques can detect drug usage at individual houses. It's just a matter of where you take your samples.
