Annual Drinking Water Quality Report
PWSID 1121150 – Dry Valley Subdivision
INTRODUCTION
This Annual Drinking Water Quality Report for calendar year 2023 is designed to inform you about your drinking water quality. Our goal is to provide you with a safe
and dependable supply of drinking water, and we want you to understand the efforts we make to protect your water supply. The quality of your drinking water must
meet state and federal requirements administered by the Virginia Department of Health (VDH).
If you have questions about this report, please contact: Don Todora, PSA Operations Specialist at (540) 381-1997
If you want additional information about any aspect of your drinking water or want to know how to participate in decisions that may affect the quality of your
drinking water, please contact: Chuck Campbell, PSA Director at (540) 381-1997
The times and location of regularly scheduled board meetings are as follows: The 1st Monday of each month at 7:00 p.m. at the Montgomery County
Government Center.
GENERAL INFORMATION
The sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels over the
surface of the land or through the ground, it dissolves naturally occurring minerals and, in some cases, radioactive material , and can pick up substances resulting
from the presence of animals or from human act ivity. Contaminants that may be present in source water include: (i) microbial contaminants, such as viruses and
bacteria, which may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife; (ii) inorganic contaminants, such as salts and
metals, which can be naturally occurring or result from urban stormwater runoff, industrial or domestic wastewater discharges , oil and gas production, mining, or
farming; (iii) pesticides and herbicides, which may come from a variet y of sources such as agriculture, urban stormwater runoff, and residential uses; (iv) organic
chemical contaminants, including synthetic and volatile organic chemicals, which are byproducts of industrial processes and p etroleum production, and can also
come from gas stations, urban stormwater runoff, and septic systems; (v) radioactive contaminants, which can be naturally occurr ing or be the result of oil and gas
production and mining activities. In order to ensure that tap water is safe to drink, EPA prescribes regulations that limit the amount of certain contaminants in water
provided by public water systems. FDA regulations establish limits for contaminants in bottled water which must provide the s ame protection for public health.
Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of contamin ants does
not necessarily indicate that water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the Environmental
Protection Agency's Safe Drinking Water Hotline (800-426-4791).
Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno -compromised persons such as persons with cancer
who are undergoing chemotherapy, persons who have undergone organ transplants, people with HIV/AIDS or other immune system di sorders, some elderly, and
infants can be particularly at risk from infections. These people should seek advice about drink ing water from their health care providers. EPA/CDC guidelines on
appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline (800-426-
4791).
SOURCE and TREATMENT OF YOUR DRINKING WATER
The source of your drinking water is groundwater as described below:
A well located within the Dry Valley Subdivision.
Is there any treatment of your drinking water supply? ( X ) Yes ( ) No
2
The Virginia Department of Health conducted a source water assessment of our system during 2020 The drilled well was determined to be of high susceptibility to
contamination using the criteria developed by the state in its approved Source Water Assessment Program. The assessment repo rt consists of maps showing the
source water assessment area, an inventory of known land use activities of conce rn, and documentation of any known contamination. The report is available by
contacting Chuck Campbell at the phone number or address given elsewhere in this drinking water quality report.
DEFINITIONS
Contaminants in your drinking water are routinely monitored according to Federal and State regulations. The table on the next page shows the results of our
monitoring for the period of January 1st to December 31st, 2023. In the table and elsewhere in this report you will find many terms and abbreviation s you might not
be familiar with. The following definitions are provided to help you better understand these terms:
Maximum Contaminant Level, or MCL - the highest level of a contaminant that is allowed in drinking water. MCLs are set as close to the MC LGs as feasible using
the best available treatment technology.
Maximum Contaminant Level Goal, or MCLG - the level of a contaminant in drinking water below which there is no known or expected risk to health. MCLGs allow
for a margin of safety.
Maximum Residual Disinfectant Level Goal or MRDLG: the level of 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.
Maximum Residual Disinfectant Level or 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.
Non-detects (ND) - lab analysis indicates that the contaminant is not present
Parts per million (ppm) or Milligrams per liter (mg/l) - one part per million corresponds to one minute in two years or a single penny in $10,000.
Parts per billion (ppb) or Micrograms per liter - one part per billion corresponds to one minute in 2,000 years, or a single penny in $10,000,000.
Picocuries per liter (pCi/L) - picocuries per liter is a measure of the radioactivity in water.
Action Level (AL) - the concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow.
Treatment Technique (TT) - a required process intended to reduce the level of a contaminant in drinking water.
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 our water
system.
Level 2 assessment - a very detailed study of the waterworks to identify potential problems and determine (if possible) why an E. coli PMCL violation has occurred
and/or why total coliform bacteria have been found in our water system on multiple occasions.

For individuals on a very low sodium diet (500 mg/day), EPA
recommends that drinking-water sodium not exceed 20 mg/L. Should you
have a health concern, contact your health care provider.
The state allows us to monitor for some contaminants less than once per year because the concentrations of these contaminants do not change frequently. Some
of our data presented in the above tables, though accurate, is more than one year old.

MCL’s are set at very stringent levels by the U.S. Environmental Protection Agency. In developing the standards EPA assumes that the average adult drinks 2 liters
of water each day throughout a 70-year life span. EPA generally sets MCLs at levels that will result in no adverse health effects for some contaminants or a o ne-in-
ten-thousand to one-in-a-million chance of having the described health effect for other contaminants.

ADDITIONAL HEALTH INFORMATION
If present, elevated levels of lead can cause serious healt h problems, especially for pregnant women and young children. Lead in drinking water is primarily from
materials and components associated with service lines and home plumbing. [NAME OF UTILITY] is responsible for providing high quality drinking water, but cannot
control the variety of materials used in plumbing components. When your water has been sitting for several hours, you can min imize the potential for lead exposure
by flushing your tap for 30 seconds to two minutes before using water for drinking or cooking. If you are concerned about lead in your water, you may wish to have
your water tested. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is ava ilable from the Safe Drinking Water
Hotline (800-426-4791).
