About Your Water Quality
Most importantly, this report shows that your drinking water source meets all primary EPA and Department of Health standards.
We hope you find this information helpful.
Your Water System
Where Your Water Comes From
Your water is pumped into the system from six wells (groundwater), which range in depth from 145 to 527 feet.
The system was optimized for corrosion control in 2011. Water entering the Parkview Terrace storage tank from Wells 1 and 2 is aerated to drive off naturally-occurring carbon dioxide in this groundwater. The aeration increases the pH of the water enough to reduce its corrosivity toward household plumbing and fixtures.
A minimal amount of chlorine is added at two of the six wells to eliminate the naturally occurring hydrogen sulfide odor (rotten eggs, sulfur).
Source Water Protection Information
What you can do to protect source water:
- Ensure that your septic system is properly maintained.
- Use chemical fertilizers and pesticides sparingly, if at all.
Check the SWAP information for your water system:
- A delineation (definition) of the source water protection area,
- An inventory of potential sources of contamination, and
- A susceptibility determination (how susceptible the source is to contamination).
An interactive map with data for your water system is available at: fortress.wa.gov/doh/swap/
- Antifreeze from a heating system
- Lawn chemicals from a garden hose or sprinkler head
- Blue water from a toilet tank
- Carbonated water from a soda dispenser
The presence of contaminants does not necessarily indicate that the water poses a health risk.
Contaminants that may be present in source water include
µmhos/cm: A measure of specific conductance.
Maximum residual disinfectant level (MRDL): The highest level of a disinfectant allowed in drinking water. There is convincing evidence that addition of a disinfectant is necessary for control of microbial contaminants.
Maximum residual disinfectant level goal (MRDLG): The level of a drinking water disinfectant below which there is no known or expected risk to health. MRDLGs do not reflect the benefits of the use of disinfectants to control microbial contaminants.
N/A: Not applicable.
Not detected (ND): The result is less than the SDRL.
Nephelometric turbidity unit (ntu): A measure of water clarity.
ppb: Parts per billion (µg/L, micrograms per liter)
ppm: Parts per million (mg/L, milligrams per liter)
The source codes indicate major sources of contaminants in drinking water.
- AHS: Water additive used to eliminate hydrogen sulfide odor
- BD: Byproduct of drinking water disinfection
- CH: Corrosion of household plumbing systems
- EN: Erosion of natural deposits
- LN: Leaching from natural deposits
- LX: Leaching from septic tanks
- NAT: Substances that form natural deposits
- NE: Naturally present in the environment
- NOM: Naturally occurring organic materials
- RF: Runoff from fertilizer use
- RGE: Runoff from glass and electronics production wastes
- RLN: Runoff/leaching from natural deposits
- RO: Runoff from orchards
- RS: Soil runoff
- SEA: Seawater influence
- SEW: Sewage
- WI: Industrial wastes
Equipment in water-testing laboratories can detect constituents as small as 1 part per trillion. That is equivalent to 1 inch over 15 million miles

2 Coliforms are bacteria that are naturally present in the environment and are used as an indicator that other potentially harmful waterborne pathogens may be present or that a potential pathway exists through which contamination may enter the drinking water distribution system. This indicates the need to look for potential problems in water treatment or in the distribution system. In August 2021, a routine sample tested positive for total coliform bacteria and negative for E. coli bacteria. Follow up bacteria samples indicated a total coliform presence in repeat samples at the Sydney Park storage tank, E. coli negative in all samples. When coliforms are confirmed present, we are required to conduct a Level 1 assessment (investigation) to identify problems and take corrective action. Chlorine as a disinfectant was added to the the Sydney Park storage tank. A new hatch seal was replaced on the tank. The tank was also inspected and cleaned. After the door hatch seal replacement and tank cleaning, the system was tested and found free of any total coliform bacteria.
3 Samples are collected at customer kitchen or bathroom taps. Residences considered to be at highest risk for corrosion are selected for sampling (i.e., those with lead and copper in internal plumbing, based on specific EPA tiering criteria and available home construction details from county web sites). The number of homes sampled is based on population served by the water system. This testing is done every three years.
4 SMCLs are guidelines only, set to control the adverse effects that minerals like manganese can cause (staining of sinks and fixtures, and dirty colored water).
5 The EPA recommends 20 ppm sodium as a level of concern for consumers who must restrict their dietary intake.
6 When reading the hardness value, 0–75 ppm is considered "soft" water, 75–150 ppm is "moderately hard," 150–300 ppm is "hard," and >300 ppm is "very hard". To convert to grains per gallon of hardness, divide total hardness by 17.1.
7 Lead and copper are regulated at customer taps (see Table 2 for those results), not at the source, which is what these results represent. This is because lead and copper in drinking water do not typically come from the water source. They come from the plumbing that serves, or is inside, the customer's home, from corrosion of lead and copper-containing plumbing or fixtures, or the lead solder that connects copper pipes.
Revised Total Coliform Rule (RTCR)
This year's report reflects changes in drinking water regulatory requirements that took effect in 2016. Effective April 1, 2016, the Revised Total Coliform Rule (RTCR) replaced the Total Coliform Rule that had been in place for public water systems since 1989. The purpose of the revised rule remains the same as the original rule, to protect public health by ensuring the integrity of the drinking water distribution system and by monitoring for the presence of microorganisms (i.e. total coliform and E. coli bacteria).
Under the RTCR, the presence of total coliform bacteria (E. coli-absent) is no longer considered a direct health threat. The maximum contaminant level (MCL) for total coliform has been eliminated. The presence of total coliform bacteria does, however, indicate that a pathway exists, or may exist, for contamination into the distribution system. The U.S. EPA anticipates even greater public health protection under the revised rule because it requires water systems to identify and fix problems that may directly or indirectly contribute to microbial contamination. It formalizes the process, requiring a qualified person to conduct a Level 1 Assessment (see definitions at right) when the system has greater than one routine coliform-positive sample in a calendar month. Any sanitary defects that are identified during the assessment must be corrected. Examples of ways that coliform can enter the system are: failure to disinfect properly after maintenance or repairs, main breaks, holes/gaps in storage tank joints and screens, loss of system pressure, cross-connections, biofilm accumulation in the distribution system, inadequate disinfectant residual (chlorinated systems), or sampling protocol errors.
The assessor records his or her findings and corrective actions onto an assessment form. The completed form must be submitted to the Washington State Department of Health (DOH) within 30 days of the treatment technique trigger (TTT), the new RTCR term for greater than one routine coliform-positive sample in a calendar month. A second TTT in a rolling 12-month period results in a more comprehensive Level 2 Assessment. A third TTT will likely result in DOH requiring permanent continuous chlorination (if the system is not already chlorinated).
Level 1 Assessment: a study of the water system to identify potential problems and determine (if possible) why total coliform bacteria have been found in the water system
Level 2 Assessment: a more detailed study of the water system to identify potential problems and determine (if possible) why total bacteria have been found in the water system more than once in a 12-month period, or why an E. coli MCL violation has occurred (if applicable)
