Further positive findings were revealed in 2009, when a study found that the water quality difference between recycled water, surface water, and groundwater showed an almost identical set of constituents of the 244 varieties they were tested for. When detected, most constituents merely appeared in parts per billion quantities, or even parts per trillion ranges. Commonly occurring ingredients included traces of the insect repellent DEET and caffeine. Significantly, these remnants were found in all water types. Meanwhile, Triclosan – an agent found in anti-bacterial soap and toothpaste – did occur in every sample, with slightly higher levels in recycled water than in surface and ground water. The most significant finding, however, was that reclaimed water contained disinfection by-products since it had been treated.
