Fog collector came on at 12:00am last night and turned off at 10:00am this morning. The sample was collected the this morning at 9:30 am and refrigerated. The collector was cleaned with soap and water, dried, then a blank was taken at 12:00pm. The sample and blank were acidified and refrigerated at 2:30pm. Today’s fog sample was a less gritty than yesterday’s.
