Are we able to meet the EPA required reporting limit of 50% of the action level for lead in dust wipes?
Lead & Metals/Chemistry/Industrial Hygiene
| Yes, for the current EPA lead action level for floors of 10 micrograms per sq. ft. and our network normalized value for FLAA is 10 micrograms per wipe. It is therefore necessary to submit a wipe area of 288 sq. inches, or 2 sq. ft. to achieve an RL of 5 micrograms per sq. ft. if selecting the FLAA method. Note that the ICP method has a detection limit of 1 microgram per wipe and thus may be a suitable alternative if it is not possible to collect a larger wipe area. |
