Too little lead to measure
26 public water companies list Durham as a place they supply. The biggest is Durham's water department, with about 333,490 people. The highest latest result among Durham's water companies is 6 parts per billion, at Fox Run S/D. None of the 26 with results was above 15 at its latest test. 22 found too little lead to measure. 24 are small systems serving fewer than 500 people each, such as a mobile home park, a subdivision or a business with its own well.
