1. Drinking Water Program OELA Spring Workshop May 15, 2009

2. Oregon Public Water Systems

3. 91 Regulated Drinking Water Contaminants (2009) 7 Microbials (bacteria, viruses, parasites) 7 Disinfection by-products (trihalomethanes, haloacetic acids) 16 Inorganic chemicals (arsenic, nitrate, lead) 56 Organic chemicals (solvents, pesticides) 5 Radiologic contaminants (uranium)

4. 102,982

5. Electronic Reporting Which results? Coliform SOCs, VOCs, IOCs (including Arsenic and Nitrate) How? Terminal server –Rapid data entry screens Computer generated file (ASCII*) –Also known as Comma Separated Value (CSV) files *American Standard Code for Information Interchange

6. Benefits of Electronic Reporting Improved tracking of samples/batches Faster incorporation of water quality data into SDWIS (Safe Drinking Water Information System) Labs have more control of data Data Integrity (verification processes built in)

7. ASCII Process (computer generated file) Drinking Water Sample Perform Analysis Submit batch to DWP (text file) DWP “gatekeeper” verifies data DWP imports data Data incorporated into SDWIS Lab’s LIMS outputs DWP Data

8. Data Requirements for Water System Compliance: VOC/IOC/SOC DWP RequirementsExample PWS ID4100731 Collection Date05/01/2009 Sample ID12345 WSF (water system facility)EP-C Sample Point1 ORELAP ID*OR100014 ResultsND Analysis Method4500NO3-D Reporting Limit (LOQ)0.1 Analyte code1040 Unit (mg/L)mg/L MRL or MDLMRL * ORELAP ID of lab performing analysis All NELAC requirements need to be followed

9. Water System Facility WSF: Designated sampling location for water system compliance –For VOC/IOC/SOC is “Entry Point to Distribution” (ie EP-A) http://170.104.63.9/labhelp.php Note: DWP is encouraging water systems to put their WSF on the lab forms Sample Point : number assigned to sampling location in SDWIS (“1”)

10. Analysis Method Method reported to DWP in text files need to match method in SDWIS http://170.104.63.9/labhelp.php

13. Login to DWP Contact DWP for username and password

14. Upload file to DWP

15. PHP “Gatekeeper” Verifies Data

16. PHP “Gatekeeper” Found Invalid Data

17. Fields Verified by PHP “Gatekeeper” PWS exists WSF and sample point (ie EP-B, 2) exists for PWS Duplicate Analysis Method matches SDWIS Unit is allowable (mg/L) Other items (contact John Davis)

18. Enter data via Terminal Server Close batch Upload batch into SDWIS Obtain proof sheet Terminal Server (TS) Process

19. Terminal Server: Coliform

20. Example: Nitrate Report

21. Terminal Server :Chems

22. Terminal Server (chems): Edit Screen

23. Customized Proof Sheet

24. MCL Exceedences * Positive Coliform samples and MCL exceedences still need to be faxed to DWP on dedicated MCL fax line.

26. Samples Due (beta status) A way to identify what samples are needed for a water system’s monitoring schedule.
