Below 15, the level that requires action
34 public water companies list Aberdeen as a place they supply. The biggest is Aberdeen's water department, with about 27,989 people. The highest latest result among Aberdeen's water companies is 8 parts per billion, at Maxwell Colony. None of the 34 with results was above 15 at its latest test. 11 found too little lead to measure. 31 are small systems serving fewer than 500 people each, such as a mobile home park, a subdivision or a business with its own well.
