The issue of the "safe level" going from 100ppb for petroleum TPH-d measurement (which was Oahu's EAL prior to DOH change) to 400ppb was mentioned two nights in a row on the news recently. KHON just said the "safe level was 400ppb" and 900ppb was found in Aiea aquifer, thus "double" the amount vs. 9x the same amount (if we use the Board of Water's standard - which is 100ppb - because at 160ppb you can "smell" petroleum in water).

If we use the Board of Water standards, the current Aiea well is NINE (9) times the safe level of 100ppb (parts per billion).
