Water System Sampling Points
Turbidity and Surface Water Treatment
Surface Water Monitoring and Reporting Forms for CT and Turbidity Data:
If your system has more than one chlorine injection point, or if you have questions about the PDF or MS Excel versions of the monthly turbidity and surface water monitoring forms, contact the Drinking Water Services technical oversight contact for your system at 971-673-0405.
Preparing a Tracer Study Plan (pdf)
Tracer Study Reporting Form (MS Excel): The template allows a water system to conduct a tracer study to comply with disinfection by determining effective contact time through a storage reservoir.

Disinfection Byproducts (DBPs)
Maximum Residual Disinfectant Levels
New sampling requirements have been added for disinfection byproducts and radionuclides that may affect your water system. Please consult the fact sheets below for further information:
Lead and Copper
- Corrosion Control Treatment (i.e., Lead and Copper Rule) Reporting Forms
- Consumer Notification Forms
- When the individual tap and the entire water system are below the action level (AL) at a community water system (fillable MS Word)
- When the individual tap and entire water system exceed the AL at a community water system (fillable MS Word)
- When the individual tap is below the AL but the entire water system exceeds the AL at a community water system (fillable MS Word)
- When the individual tap exceeds the AL but the entire water system is below the AL at a community water system (fillable MS Word)
- When samples exceed the AL at a non-transient non-community water system (fillable MS Word)
- When samples are below the AL at a non-transient non-community water system (fillable MS Word)
- Certification to Drining Water Services that consumer notification has been completed (fillable MS Word)
- Lead and Copper Sample Site Selection Form: Systems that would like to change lead and copper tap sampling site locations, need to receive approval from the regulatory agency (DWS or local health agency) prior to conducting the sampling at the new locations. Systems will need to request the change on the EPA 141-A form.
- Lead Testing: EPA's Lead in Drinking Water in Schools and Non-Residential Buildings manual describes how drinking water can be tested for lead and how contamination problems can be corrected. This manual is intended for use by school officials responsible for the water system maintenance and/or safety. Revised technical guidance is available in EPA's 3Ts for Reducing Lead in Drinking Water in Schools (pdf). Visit EPA's website for more information on Testing Schools and Child Care Centers for Lead in the Drinking Water (including where to sample, before you sample, how to sample and sample results). For more information about lead poisoning, please contact the Oregon Lead Poisoning Prevention Program (phone 971-673-0440).
