Can You Drink Tap Water in Terrebonne Parish?
Yes, Terrebonne Parish's tap water is generally considered safe to drink as Terrebonne Parish has no active health based violations of the Safe Drinking Water Act (SDWA) that we are aware of. Other factors such as lead piping in a home, or low levels of pollutants on immunocompromised individuals, should also be considered, however. To find more recent info we might have, you can check out our boil water notice page or the city's water provider website.
According the EPA’s ECHO database, from April 30, 2019 to June 30, 2022, Terrebonne Parish's water utility, Schriever Water Treatment Service Area, had 1 non-health-based violations of the Safe Drinking Water Act. For more details on the violations, please see our violation history section below. The last violation for Terrebonne Parish was resolved on April 30, 2021. This assessment is based on the Schriever Water Treatment Service Area water system, other water systems in the city may have different results.
While tap water that meets the EPA health guidelines generally won’t make you sick to your stomach, it can still contain regulated and unregulated contaminants present in trace amounts that could potentially cause health issues over the long-run. These trace contaminants may also impact immunocompromised and vulnerable individuals.
The EPA is reviewing if it’s current regulations around pollutant levels in tap water are strict enough, and the health dangers posed by unregulated pollutants, like PFAS.
Water Quality Report for Terrebonne Parish Tap Water
The most recent publicly available numbers for measured contaminant levels in Terrebonne Parish tap water are in its 2020 Water Quality Report. As you can see, there are levels which the EPA considers to be acceptable, but being below the maximum allowable level doesn’t necessarily mean the water is healthy.
Lead in tap water, for example, is currently allowed at up to 15ppb by the EPA, but it has set the ideal goal for lead at zero. This highlights how meeting EPA standards doesn’t necessarily mean local tap water is healthy.
EPA regulations continue to change as it evaluates the long term impacts of chemicals and updates drinking water acceptable levels. The rules around arsenic, as well as, lead and copper are currently being re-evaluated.
There are also a number of "emerging" contaminants that are not currently. For example, PFAS (Per- and polyfluoroalkyl substances), for which the EPA has issued a health advisory. PFAS are called "forever chemicals" since they tend not to break down in the environment or the human body and can accumulate over time.
We recommend looking at the contaminants present in Terrebonne Parish's water quality reports, or getting your home's tap water tested to see if you should be filtering your water.

Is there Lead in Terrebonne Parish Water?
Based on the EPA’s ECHO Database, 90% of the samples taken from the Terrebonne Parish water system, Schriever Water Treatment Service Area, between sample start date and sample end date, were at or below, 0.0 mg/L of lead in Terrebonne Parish water. This is 0% of the 0.015 mg/L action level. This means 10% of the samples taken from Terrebonne Parish contained more lead.
While Terrebonne Parish water testing may have found 0.0 mg/L of lead in its water, that does not mean your water source has the same amount. The amount of lead in water in a city can vary greatly from neighborhood to neighborhood, or even building to building. Many buildings, particularly older ones, have lead pipes or service lines which can be a source of contamination. To find out if your home has lead, we recommend getting you water tested.
No amount of lead in water is healthy, only less dangerous. As lead accumulates in our bodies over time, even exposure to relatively small amounts can have negative health effects. For more information, please check out our Lead FAQ page.
Are there PFAS in Terrebonne Parish Tap Water?
Currently, testing tap water for PFAS isn’t mandated on a national level. We do have a list of military bases where there have been suspected or confirmed leaks. There appears to be no military bases near Terrebonne Parish with suspected leaks.
With many potential sources of PFAS in tap water across the US, the best information we currently have about which cities have PFAS in their water is this ewg map, which you can check to see if Terrebonne Parish has been evaluated for yet.
Our stance is better safe than sorry, and that it makes sense to try to purify the tap water just in case.

INFORMATIONAL STATEMENTS and
WARNINGS
1. 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 |
some cases, radioactive material, and can pick up substances |
resulting from the presence of animals or human activity. |
2. Contaminants that may be present in source water include: |
a. Microbial contaminants, such as viruses and bacteria, |
which may come from sewage treatment plants, septic |
systems, agricultural livestock operations and wildlife. |
- Some people who drink water containg trihalomethanes or haloacetic acids in excess of the MCL over many years may experience problems with their liver, kidneys, or central nervous system and may have an increased risk of getting cancer.
- If present, elevated levels of lead can cause serious health 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 components. Consolidated Waterworks 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 minimize the potential for lead exposure by flushing your tap for 30 seconds to 2 minutes before using the 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 available from the Safe Drinking Water Hotline or at http://www.epa.gov/safewater/lead.
GENERAL INFORMATION
The Board of Commissioners conducts its public meetings twice per month in the Main Office Board Room at 8814 Main Street, Houma, Louisiana at 5:30 PM on the first and third Mondays of each month. Meetings may be
Water quality is tested throughout the year to adhere to strict guidelines and regulations set forth by Consolidat- ed Waterworks District No. 1, the State of Louisiana Department of Health and the Federal EPA. Consolidated Waterworks is committed to serving safe clean water to all of its customers. The Environmental Protection Agency has mandated that community water systems annually inform their customers of the quality of water delivered by the system. Consolidated Waterworks District No. 1 is also required to inform you of certain risks and possible contaminants that may be contained in drinking water.
Consolidated Waterworks District No. 1 currently operates two independent water treatment plants distrib- uting water to separate sections of Terrebonne Parish. Under certain emergency conditions, water may come from either plant. The primary difference between the two plants is the water source. Both plants utilize the coagu- lation, sedimentation, filtration, and disinfection process to treat the surface source water. Granular activated carbon and sand filters are utilized to filter water and adsorb many organic and some inorganic compounds. This adsorption process greatly enhances the water's taste and odor characteristics. Chlorine is the primary plant disinfectant. Chloramine disinfectant is injected prior to water entering the distribution system.
b. Inorganic contaminants, such as salts and metals, which |
can be |
runoff, industrial or domestic wastewater discharges, oil |
and gas production, mining, or farming. |
c. Pesticides and herbicides, which may come from a variety |
of sources such as agriculture, urban stormwater runoff, |
and residential uses. |
d. Organic chemical contaminants, including synthetic and |
volatile organic chemicals, which are |
industrial processes and petroleum production, and can |
also come from gas stations, urban stormwater runoff, |
and septic systems. |
e. Radioactive contaminants, which can be |
ring or the result of oil and gas production and mining |
activities. |
3. In order to ensure that tap water is safe to drink, EPA prescribes |
regulations which 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 same protection for public health. |
4. Drinking water, including bottled water, may reasonably be |
expected to contain at least small amounts of some contami- |
nants. The presence of contaminants 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 at |
5. Some people may be more vulnerable to contaminants in |
drinking water than the general population. |
mised persons such as persons with cancer undergoing chemo- |
therapy, persons who have undergone organ transplants, |
people with HIV/AIDS or other immune system disorders, some |
elderly, and infants can be particularly at risk from infections. |
These people should seek advice about drinking 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 at |
WATER SOURCES
SCHRIEVER WATER TREATMENT PLANT:
Surface Water from Bayou Lafourche. The bayou runs from Donaldsonville, LA to the Gulf of Mexico. The bayou obtains most of its water from the Mississippi River @ Donaldsonville, LA.
HOUMA WATER TREATMENT PLANT USES TWO
SOURCES OF WATER:
PRIMARY: Surface Water from Gulf Intracoastal Waterway (generally
flows east/west along coastal Louisiana and other Gulf states: rain water runoff, Mississippi River influence, Atchafalaya River influence, and tidal water influence)
SECONDARY: Bayou Black (when the Intracoastal Canal becomes too
salty: chlorides greater than 250 ppm)
SOURCE WATER ASSESSMENT: A source water assessment has been performed for both the Schriever & the Houma Water Treatment Plants. The reports and the area maps may be viewed at Consolidated Waterworks District No. 1's office at 8814 Main Street, Houma, LA

MCLG: Maximum Contaminant Level Goal: 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.
MCL: Maximum Contaminant Level: The highest level of a contaminant that is allowed in drinking water. MCLs are set as close to the MCLGs as feasible using the best available treatment technology.
MRDL: Maximum Residual Disinfectand Level: 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.
MRDLG: Maximum Residual Disinfectant Level Goal: The level of a drinking water disinfectant below which there is no known or expected risk to health. There is convincing evidence that addition of a disinfectant is necessary for control of microbial contaminants.
N.D.: Non Detected: Laboratory analysis indicates that the contaminant is not present.
ppm: Parts per Million: One part per million corresponds to 1 minute in 2 years or a single penny in $10,000.00
ppb: Parts per Billion: One part per billion corresponds to 1 minute in 2000 years or a single penny in $10,000,000.00
pCi/L: Picocuries per Liter is a measure of the radioactivity in water.
NTU: Nephelometric Turbidity Units: Is a measure of the clarity of water. Turbidity in excess of 5 NTU is just noticeable to the average person.
AL: Action Level: The concentration of a contaminant that, if exceeded, triggers treatment or other requirements that a water system must follow.
