According to ecology writer Jacqueline Killen, phosphates contained in household detergents pass right through our sewer systems causing lakes to turn into swamps that eventually dry up into deserts. The following data shows the amount of phosphates per load of laundry, in grams, for a random sample of various types of detergents. 21.5 26.3 29.2 37.8 46.3 32.2 44.5 22.3 28.6 30.3 38.9 47.5 28.3 36.2 23.2 29.8 31.5 41.3 48.5 17.1 29.1 24.1 29.4 33.6 42.4 49.6 31.0 33.8 25.9 29.1 34.9 42.6 51.8 22.4 27.1
