What is all Community Water Systems
These water systems must comply with the Sodium Rule

100

What is one group is Synthetic and the other is Volatile.
The primary difference between SOCs and VOCs.

100

What is until water from the main is flowing through the tap. Time varies depending on the length of the service line.
How long should the water be run from a tap prior to collecting samples for Total coliforms and Free Chlorine Residual?

100

What is 1986.
This is the year that lead solder was outlawed for use in plumbing systems.

100

What is 2-Log Removal (99 percent)
The treatment technique (TT) requirement for Cryptosporidium.

200

What is annually.
Surface water systems are required to monitor for sodium at least __________.

200

What are Unregulated Contaminants
Aldicarb, aldicarb sulfoxide, and aldicarb sulfone are currently under administrative stay as a result of litigation. While you don't have to comply with the MCL, these compounds are treated as:

200

What is Chloramines.
A system using this type of disinfectant will sample for Total Chlorine Residual instead of Free Chlorine Residual and may sample for both.

200

What is Tier 1. Tier 1 also includes homes with lead pipes or lead service lines.
For Community Water Systems, single-family structures that contain copper pipes with lead solder that were installed after 1982 are classified as this:

200

What is 3-Log Removal (99.9 percent)
The treatment technique (TT) requirement for Giardia lamblia.

300

What is every three years.
Groundwater systems must monitor for sodium at least ______________.

300

What is when all initial sampling results are less than the method detection limits OR After three consecutive years of annual sampling following detection of a VOC, all sample results are less than the MDL.
Sampling waivers for VOCs may be issued by the State if this is true:

300

What is 6 hours prior to sampling.
When collecting a lead and copper sample, the water must be stagnant in the line for at least

300

What is 1.3 mg/L.
The action level for Copper in mg/L.

300

What is 4-Log Removal (99.99 percent)
The treatment technique (TT) requirement for viruses.

400

What is the State determines that a single entry point is representative of multiple entry points
Samples must be collected at each entry point unless:

400

What is the Locational Running Annual Average (LRAA)
For systems that sample for SOCs or VOCs more often than annually, compliance is based on:

400

What is Glass, Zero-Head Space
When sampling for VOCs, this type of container is used.

400

What are Automatic Sprinkler Systems (and anything else that uses water).
If residents will collect samples for Lead and Copper analysis, they should be reminded to turn off automatic ice makers, swamp coolers, and ___________________.

400

What is Filtration
All surface water systems are required to provide _______________ of their treated water.

500

What is between 30 and 60 mg/L based on esthetic effects (i.e., taste). This recommendation is not federally enforceable but is intended as a guideline for States. A goal of 2.4 g/day dietary sodium has been proposed by several government and health agencies. Drinking water containing between 30 and 60 mg/L is unlikely to be perceived as salty by most individuals and would contribute only 2.5% to 5% of the dietary goal if tap water consumption is 2 L/day.
EPA issued an advisory in 2003 that recommended reducing sodium concentrations in drinking water to these levels.

500

What is Notify the State within 48 hours AND distribute Tier 2 public notices.
If an organic chemical MCL is violated or an acrylamide or epichlorohydrin treatment technique violation has occurred, the water supplier must:

500

What is Certified Laboratory Analyst or Certified Laboratory Personnel
Only this person or group of people may composite samples for nitrate, nitrite, inorganic chemicals, VOCs, and SOCs under the Colorado Primary Drinking Water Regulations.

500

What are Passivating Films (pH, alkalinity, and calcium control) and Surficial Coatings (polyphosphates and silicates).
EPA recognizes two main groups of chemical treatment for Corrosion Control in distribution systems. They are:

500

What is the Filter Backwash Rule
This rule requires backwash water from Conventional or Direct filtration systems and filtrate/centrate from solids dewatering to be returned upstream of filtration.
