* 1995 at Univ. of IL printers and will be available by mid to late October.
* The annual reports are now Jane RothertĂs responsibility.
* 12 attendees at the CAL May, 1997 course.
* Plans are being made for 1998.
INTERLABORATORY COMPARISON STUDIES UPDATE
WMO/GAW Intercomparison Study
The 19th World Meteorological Organization (WMO)/ Global Atmospheric Watch (GAW) Laboratory Intercomparison Study was conducted last year by the State University of New York at Albany (SUNYA). In previous years, the samples used in these studies had been made at the USEPA. In 1996, the CAL was invited to prepare these samples, confirm their concentrations, and bottle and package the samples for shipment to SUNYA. In September 1996, the CAL prepared and shipped about 100 bottles of concentrated samples for distribution worldwide.
The CAL was again contracted in 1997 to prepare the samples for the 20th WMO/GAW Laboratory Intercomparison Study. This year ten (10) concentrated and 120 diluted sets of samples were sent to SUNYA. Thirty sets of samples for metals analysis were also prepared. Results of the 20th Study are due at the SUNYA by the middle of November.
National Water Research Institute (NWRI) Ecosystem Interlaboratory QA Program Studies FP70 and 71 - Rain and Soft Waters
The results of FP70 had the CAL ranked ideal for all components except for pH, Nitrate by IC, and Calcium by AA. One sample was flagged high for nitrate and one sample was flagged low for calcium. Four out of ten samples were ranked high, very high or extremely high for pH indicating that the CAL has a HIGH bias with pH. NWRI uses the laboratory median values as the "true" values for all analyses.
Study FP71 is due to NWRI in Canada by the end of October. In this study, no pHĂs are below 5.2.
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.
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.
* 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
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.
