CAL REPORT

 

PERSONNEL CHANGES


Chemical Analytical Services

Data Validation Services

pH ELECTRODE UPDATE

* 127 new and used electrodes sent from Oct. 1, 1996 to Oct. 1, 1997.

* Overall turnaround in electrodes ~1.6 years.


QA REPORTS

* 1995 at Univ. of IL printers and will be available by mid to late October.

* The annual reports are now Jane RothertĂs responsibility.


TRAINING COURSE

* 12 attendees at the CAL May, 1997 course.

* Plans are being made for 1998.


INTERLABORATORY COMPARISON STUDIES UPDATE

WMO/GAW Intercomparison Study

National Water Research Institute (NWRI) Ecosystem Interlaboratory QA Program Studies FP70 and 71 - Rain and Soft Waters

pH 4.9 CHECK SOLUTION

The pH 4.9 check solution has been in use on the network since Jan. 2, 1996. The CAL prepares about 100 liters of 4.9 check sample once every 2 months, or the network uses about 600 liters per year.


FIA COMPUTERIZED

The first electronic data capture for ammonium and phosphate by flow injection analysis was on April 15, 1997. Currently, all analytical measurements except pH and conductivity are captured electronically.


NETWORK EQUIPMENT DEPOT (NED) IMPLEMENTATION

The NED has replaced the Coordination Office Equipment Depot (COED). As of 1 September all replacement components are being sent to sites from the NED.

A new mailing and inventory system (bar code) will be described by Scott in a report to the NOS.


11-GRID VS. 7-GRID SENSOR TEST

An experiment comparing an 11-grid with a 7-grid precipitation sensor was completed in the ISWS back yard. Scott Dossett will present the details of the experiment in a poster.


EPA SITE AUDIT PROGRAM/TRAINING NEW SITE AUDITORS

Scott Dossett presented a draft schedule for training new site auditors to Thomas Lumpkin at the USEPA. Scott discussed with the EPA the possibility of the new auditing firm operating a "site" and supplied the EPA with cost information.


OPERATORS MANUAL REBUILD

Progress on organizing and writing a revised NADP Operators Manual has slowed due to the Coordination Office move to the ISWS. Pictures and schematic diagrams in the manual are being digitized. The goal is to develop a document that is accessible via the Worldwide Web.


ANNUAL LID SEAL REPLACEMENT

* Lid seals were changed on June 24, 1997.

* To date all but 10 sites have had confirmed changes.

* 4 sites were sent letters about especially dirty lid seals.

* 20 sites were classified as having off center lid seal impressions.


AIRMoN

* Archival Samples were sent to Tyler Coplen of the USGS in Reston, VA for analysis of radioactive isotopes. 1118 bottles were shipped.

* The e-FOF is in final testing. The rules will be added the first of November. By the first of the year, all but one site should be using the e-FOF on a full time basis.

* New site - there is a potential new site in Sarasota, FL.

* NGS KidĂs Network - pH data are still being sent to NOAA for the National GeographicĂs KidĂs Network. Jane Rothert reviewed new text that describes pH measurements of acid rain and general information about acid deposition and collection.

* The AIRMoN Site OperatorĂs Manual was published as a NOAA Technical Memorandum in April.

* The AIRMoN QA Manual is in the process of being rewritten using Data Quality Objectives (DQOĂs).


SPECIAL RESEARCH PROJECTS

Gelman Filters

A new type of Gelman filter was tested to see if the positive bias for sodium seen with the Millipore filters is better or worse. Preliminary results are very positive.

New new bucket cleaning procedures

New buckets have been cleaned using various combinations of prewashing, acid leaching, and check solution/blank verification. We would like to standardize the procedure and incorporate it into the regular bucket washing protocols. The new method will formalize how new buckets are introduced into the system.

new pH meter/computer - Orion

The CAL is currently a Beta lab for testing OrionĂs new pH meter in a computer. This is a regular computer with a special attachment and software that turns the computer into a pH meter.

Ammonium stability study

Sue Bachman, Van Bowersox, and Pam Scales have begun exploring various ways to study the degradation of ammonium and other biologically sensitive constituents in acid precipitation.

Omnimark pH meter

Omnimark Instrument Corp. has a new electrode out, the IQ200 pH system. It is an electrode/meter combination. The electrode is stainless steel rather than glass. The CAL is in the initial stages of testing this new type meter and probe.


UPS STRIKE AND ITĂS AFFECT ON THE CAL AND SAMPLE SHIPPING

On August 5, the UPS went on strike. The majority of the sites, about 90%, sent the samples using US Postal Service with the rest using Federal Express. Thirty sites did not send samples at all during the strike period, approximately Aug. 5 through Aug. 20.

During the strike period, approximately 500 mailers were sent from the CAL. The normal cost for sending these mailers would have been $3000 when sent by UPS. The cost during the strike was $6500 or an increase of 117%.

With the strike over on Aug. 20, the CAL thought they would be back to normal within a week or so. On Sept. 8, the CAL received 115 mailers and sent out 88. On Sept. 9, the CAL received 68 mailers and sent out those 68 plus the 27 left over from the day before, making a total shipped of 95. The two-day total was 183 samples! By weeks end, 275 samples were received and processed and all sites were caught up with their backlog of samples from the strike.


IN-HOUSE TECHNICAL REVIEW

Mark Peden, Karen Harlin, and Jane Rothert will be conducting an in-house technical review of the CAL laboratory and shipping and receiving operations in November.
