Monitoring Plan Template Chris Crawford, Ph.D. Water Resource Specialist Cattaraugus County Health Department
Exercise #1 • Name 5 Parameters a Public Water System may monitor for (and why?) • Using the 5 parameters above, decide where you would monitor for them (and why?)
Exercise #1 • Using the 5 parameters above, decide when you would monitor for them (and why?) • Using the 5 parameters above, determine what types* of systems should monitor for them (and why?) * Surface v. Ground, Com. v. NTNC v. NC, Population size, connection size, treatment processes.
Exercise #1 • Using the 5 parameters above, what are important considerations in conducting the monitoring (and why?) • Using the 5 parameters above, what is the best way to store the information (and why?) • Who should be aware of the monitoring data (and why?)
Congratulations!!!!!! You’ve Made Your First Monitoring Plan
10 NYCRR 5-1 Revisions “Each system must develop and implement a monitoring plan that includes all monitoring requirements specified in this Subpart. This plan must be completed by January 31, 2012. …. The monitoring plan must include at least the following elements, as applicable: (1) specific locations and schedules …; (2) how the system will calculate compliance …; (3) if the system is a consecutive system, or it is providing water to a consecutive system, …. the sampling plan must reflect the entire distribution system … (4) consecutive ground water systems must define and implement a protocol for notifying the system from which they receive water of any total coliform positive samples…
5-1.76 Consecutive public water systems. (b) Consecutive systems must follow section 5-1.52 Table 11B of this Subpart in the event of a total coliform positive sample from their distribution system. When a consecutive system that receives ground water from a wholesale system is notified of a positive total coliform sample result, the consecutive system must, within 24 hours, notify the State, the wholesale system and any other wholesale system that owns and/or operates ground water sources that provides water used by the consecutive system. ….

Types of Monitoring • Regulatory • Operational • Event
Monitoring Types - Regulatory No Choice! We gotta do it! • Primary / Direct relationship to risk • (indicator) • Supports threshold values (MCLs) • Triggers other regulatory requirements • (often additional monitoring) • Public Health
Monitoring Types - Operational • Secondary / Indirect relationship to risk • (indicator?) • Supports threshold values for system • operations (SOPs?) • Triggers other operational requirements • System Operations We should do this. (or do we have to – ‘due diligence’)
Monitoring Types - Event • Reactive / Direct or Indirect relationship • to risk • Assess environment /system (SOPs?) • (causal / pre-event) • Assess response effectiveness (action / post) We should do this. (or do we have to – ‘due diligence’)
Monitoring Types Regulatory Operational Event
Exercise #2 • Using the 5 parameters noted earlier, decide what type of monitoring it is (hint: there may be more than one type for each parameter)
Exercise #2 • For each parameter noted earlier that falls into more than 1 type answer the following: - Are there different locations depending on type (and why)? - Are there different frequencies depending on type (and why)? - Are there different considerations depending on type (and why)? - Are there different result storage methods depending on type (and why)? - Are there different postions that need to know depending on type (and why)?
Need to Know -System Type • Regulatory • Operational • Event
5-1.76 Consecutive public water systems. “(a) When a public water system supplies water to one or more consecutive public water systems, the State may modify the monitoring requirements of this Subpart when the circumstances justify treating them as a single system for monitoring purposes. Any modified monitoring shall be conducted pursuant to a schedule approved by the State, in accordance with the provisions of sections 5-1.51 and 5-1.52 of this Subpart.”
Need to Know –Distribution System Is this enough?
Types of Sampling Points a tap used to draw a cold water sample for lead and copper, where the water is believed to sit in the plumbing system for six hours. a tap in the distribution system • Entry Point • Raw Water • Finished Water • Maximum Residence • Average Residence • Post Treatment • Pre-treatment • First draw • Combined Filter Effluent (CFE) • Individual Filter Effluent (IFE) • Distribution • Lead Service Line • First Customer a representative sampling location where it is believed, based on either hydraulic modeling or operator experience, that water remains in the pipe for an average amount of time when looking at the entire distribution system. a sample tap used to collect a sample where water has stood in a lead service line for at least six hours. a representative sampling location after the last point of treatment. Cannot be after the first customer. a representative sampling location before the first treatment process. a representative sample location before one or more treatment processes. a representative sampling location where it is believed, based on either hydraulic modeling or operator experience, that water remains in the pipe longer than anywhere else in the distribution system. in filtered systems, a tap downstream of an individual filter. a representative sampling location, similar to entry point, that is inside the treatment plant. in filtered systems, a tap downstream of the location where effluent from each filter combines. a sampling location where water is first distributed to a customer. a representative sample location after one or more treatment processes.
