1. Sample Siting Plans under the Revised Total Coliform Rule
Rick Hiers, SC DHEC
SCRWA RTCR Compliance Workshop
Florence, SC • January 20, 2016
Specific requirement under RTCR

2. Sample Siting Plan (SSP) Topics
SSP as part of Standard Operating Procedures (SOP) for coliform monitoring
SSP requirements under Revised Total Coliform Rule (RTCR)
SSP components
1. SSP is just a document that specifies where and when coliform samples will be taken, but are part of overall SOP. SOP is system’s, required by regs, under O&M section, but will include lab’s procedures. Communication is key – have each others procedures 2. Anything new?

3. SOP for Coliform Monitoring
Written document
Components
SOP review/revision tracking sheet w/signature & date lines
Title page with water system name & number, date prepared
SOP contact person and contact information
Purpose of SOP – Instruct, comply
Lab needs to know about revisions that affect them

4. SOP Review/Revisions Tracking Sheet
Date
Reviewer Signature
Revisions
Made
Whenever necessary,
but at least annually
System & lab should both have revision sheets for their procedures.

5. SOP for Coliform Monitoring
Components
Sample collector
Water system
Commercial laboratory, other contracted party
Include contract in SOP, give copy of SOP to contractor
Laboratory that will be performing the analyses
Contact information
Sampling /analytical specifics
Repeat samples within 24 hours
E. coli analyses for all total coliform positive (TC+) samples
GWR-triggered well samples within 24 hours
Several combos of collecting, analyzing: system/system, system/contract lab, contract lab/contract lab, other/contract lab

6. SOP for Coliform Monitoring
Components
Site selection
Easily accessible (dedicated taps are ideal)
Representative
Avoid
Swivel/leaky faucets
Commercial/janitorial sinks
Spigots close to ground
Inside-threaded spigots
Upward-pointing spigots
Aerators/hoses
Sample Siting Plan

7. SOP for Coliform Monitoring
Components
Sampling protocol
Sample collection equipment
Sample collection procedures
Bottle filling
Chain-of-custody
Other parameters to collect
Results tracking
Notification Procedures
DHEC (contact information)
Consumers
Violations
Boil water advisories and notices
Video on coliform sampling coming up next

8. SSP Requirements Written SSP that identifies: Sampling sites
Routine samples
Repeat samples
Ground Water Rule-triggered well samples
Sampling schedule
We’ll discuss repeat sample sites in a couple of slides

9. SSP Requirements
Sites and schedule must be representative of water throughout the distribution system
SSP is subject to State review and revision
DHEC is not requiring SSPs to be submitted
DHEC will review drafts, but not at the 11th hour
Maintain on site, DHEC will review during sanitary surveys
Must sample according to plan
Complete no later than March 31, 2016
If have to move ( frozen, etc.), go to closest good site, note on form. If permanent move, revise SSP.

10. Representative Sampling Sites
Ensure that there is no place in the distribution system where coliform contamination could persist undetected
Consider
Entry points
Population densities
Pressure zones
Distribution treatment locations
Water demand
Dead ends
Other potential problem areas

11. SSP Components Title with water system name & # Purpose
General system information
SSP contact person and contact information
Water source
Type of disinfectant added
Booster disinfection?

12. SSP Components General system information Approximate number of taps
Approximate population served
Minimum required number and collection frequency of routine total coliform samples
Same day for <6 samples/month, spaced throughout month for > 6 samples/ month
Actual number and collection frequency of routine total coliform samples

13. SSP Components List of sampling locations Numbered Physical addresses
Latitude/Longitude
Other descriptor
Routine sites (designate rotational sites)
Repeat sites (or state TC+ site, within 5 taps upstream of TC+ site, and within 5 taps downstream of TC+ site)
Triggered well sites under GWR (if applicable)

14. SSP Components Map of distribution system
Routine sample sites (rotationals)
Repeat sample sites (if specific locations chosen)
GWR-triggered well sites (if applicable)
Other features
Entry points
Tanks
Distribution treatment facilities
Pressure zones
Hydrants/blow offs
Pipe sizes and materials
Small – hand drawn; Large - GIS
