SURF Personnel:

Location(s): 4850 West Drift




Planned Tasks: Water Sampling, Chiller Water Level Inspection, E1-I Collar Flowmeter and funnel cleanup, & Seismic Workstation Troubleshoot.


·      Caged down at 7:00 am with a dry ice cooler and ultrapure water.

·      Upon arrival on-site, a visual inspection was done across the drift.


·      Chiller water level was checked and looked normal.


·      E1-I Collar Flowmeter was showing infrequent spikes in flowrate and was suspected to be dirty. The funnel, tubing, and the flowmeter were all flushed with water. Some ultrapure water was also utilized to help further clean the parts.


·      Seismic Workstation was not responding to any commands sent to it. It was speculated to have shut down due to a tripped breaker, but upon inspection of the breaker box, this wasn’t the case. The computer used to communicate with the system was found to be the one with the issue and was resolved quickly.


·      While checking the breaker box, it was noticed that circuit 26 had tripped. The Kloehn pump and the ISCO pumps are the only equipment connected to the circuit. Kloehn pump was unplugged from the circuit since it was faulty and wasn’t running beforehand. The ISCO pumps shut-off because of the circuit trip. Tim Baumgartner was passing through the drift with a tour and kindly reset the tripped circuit breaker. The ISCO pumps were up and running after the reset.


·      Collected water samples from the flowing boreholes PST, PDT, PB, PI and Injectate using 4L containers.

·      A peristaltic pump was used to circulate the water from the containers through silicone hoses and into a 5-gallon wastewater collection bucket.

·      PH level from each water sample was tested and noted down using PH test strips.

·      Geochem samples were collected from the 4L containers using 50ml Falcon tubes and were stored in the cooler.

·      Water sample from each container was filtered through Sterivex GP 0.22µm filters, which were immediately stored in the cooler.

·      All containers and silicone hoses were sterilized using ultrapure water and 5% Hydrochloric Acid. A face shield was utilized during sterilization.

·      Two empty 500 ml plastic bottles were labeled and used to store waste 5% HCl.

·      Caged up at 4:00 pm.

·      All samples and filters were transported, stored, and frozen in the -80 °C freezer in CCBR lab at 5:20 pm.
