Inorganic Contaminants
Please note, during the First Quarter 2016 we failed to complete required sampling for Stage 2 Disinfectant Byproduct samples on time and therefore were in violation of applicable monitoring and reporting requirements. Because we did not conduct the required monitoring, we could not con�rm the levels of Stage 2 Disinfectant Byproducts present in your drinking water, and potential health effects, if any, were unknown during the monitoring period. The monitoring period was 01/01/16 through 03/31/16. Four (4) samples were required for each contaminant (Haloacetic Acids and Total Trihalomethanes), and none were taken during the referenced period. Sampling was conducted on 04/26/16 and indicated the levels were below the applicable MCLs.
T E S T R E S U L T T A B L E S 2016Annual Drinking WaterQualityReport
PSW ID# 6291882
We are pleased to present to you this year’s Annual Water Quality Report. This report is designed to inform you about the quality of water and services we deliver to you every day. Our constant goal is to provide you with a safe and dependable supply of drinking water.
Our water is sourced from five ground water wells at depths from 120 to 340 feet and the City of Tampa Water System. The water, pumped from the Floridan Aquifer, is chlori-nated for disinfection purposes, treated with zinc phosphate for corrosion control, and distributed to the campus. Greek Housing and USF Health are supplied separately by the City of Tampa Water System.
The Florida Department of Environmental Protection (FDEP) conducted a statewide assessment of public drink-ing water systems beginning in 2004. The assessment was conducted to provide information about any potential sources of contamination in the vicinity of our wells. There are 12 potential source(s) of contamination identified for this system with a moderate susceptibility level(s). The assessment results are available on the FDEP Source Water Assessment and Protection Program website at www.dep.state.fl.us/swapp. If you have any questions con-cerning this report or your water utility, please contact William Land, Director, Environmental Health & Safety, Facilities Management, at (813) 974-4036. We encourage our customers to be informed about their water utility.
The University of South Florida routinely monitors for contaminants in your drinking water according to Fed-eral and State laws, rules, and regulations. Except where indicated, this report is based on the monitoring results for the period of January 1 to December 31, 2016. Data obtained before January 1, 2016 and presented in this report are from the most recent testing done in accordance with the laws, rules and regulations. This report shows our water quality results and what they mean.
In the tables on the following pages, you may find terms and abbreviations that may not be familiar to you. To famil-iarize you with these terms, we have provided the follow-ing definitions:
AL (Action Level): The concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow.
IDSE (Initial Distribution System Evaluation): An important part of the Stage 2 Disinfection Byproducts Rule (DBPR). The IDSE is a one-time study conducted by water systems to identify distribution system locations with high concentrations of trihalomethanes (THMs) and haloacetic acids (HAAs). Water systems will use results from the IDSE, in conjunction with their Stage 1 DBPR compliance mon-itoring data, to select compliance monitoring locations for the Stage 2 DBPR.
LRAA (Locational Running Annual Average): The average of sample analytical results or samples taken at a particular monitoring location during the previous four cal-endar quarters.
MCL (Maximum Contaminant Level): The highest level of a contaminant that is allowed in drinking water. MCLs are set as close to the Maximum Contaminant Level Goals (MCLGs ) as feasible using the best available treat-ment technology.
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.
MRDL (Maximum residual disinfectant level): The highest level of a disinfectant allowed in drinking water. There is convincing evidence that addition of a disinfectant is nec-essary 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. MRDLGs do not reflect the benefits of the use of disinfectant to control microbial contaminants.
N/A: Means not applicable.
ND: Means not detected and indicates that the substance was not found by laboratory analysis.Units:
Parts per billion (ppb) or Micrograms per liter (µg/l) – one part by weight of analyte to 1 billion parts by weight of the water sample.
Parts per million (ppm) or Milligrams per liter (mg/l) – one part by weight of analyte to 1 million parts by weight of the water sample.
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 occur-ring minerals and, in some cases, radioactive material, and can pick up substances resulting from the presence of ani-mals or from human activity.
If present, elevated levels of lead can cause serious health problems, especially for pregnant women and young chil-dren. Lead in drinking water is primarily from materials and components associated with service lines and home plumbing. USF is responsible for providing high quality drinking water, but cannot control the variety of materi-als used in plumbing components. When your water has been sitting for several hours, you can minimize the poten-tial for lead exposure by flushing your tap for 30 seconds to 2 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 drink-ing water, testing methods, and steps you can take to min-imize exposure are available from the Safe Drinking Water Hotline or at www.epa.gov/safewater/lead.
Contaminants that may be present in source water include:
(A) Microbial contaminants, such as viruses and bac-teria, which may come from sewage treatment plants, sep-tic systems, agricultural livestock operations, and wildlife.
(B) Inorganic contaminants, such as salts and met-als, which can be naturally-occurring or result from urban stormwater runoff, industrial or domestic wastewater dis-charges, 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 syn-thetic and volatile organic chemicals, which are by-prod-ucts of industrial processes and petroleum production, and can also come from gas stations, urban stormwater runoff, and septic systems.
(E) Radioactive contaminants, which can be natu-rally occurring or be the result of oil and gas production and mining activities.
Special Information for Immuno-Compromised People Should KnowAbout Drinking WaterSome people may be more vulnerable to contaminants in drinking water than the general population. Immuno-com-promised persons such as persons with cancer undergoing chemotherapy, persons who have undergone organ trans-plants, 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. Environ-mental Protection Agency (EPA) and Center for Disease Control guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other micro-biological contaminants are available from the Environ-mental Protection Agency’s Safe Drinking Water Hotline at 1-800-426-4791.
In order to ensure that tap water is safe to drink, EPA pre-scribes regulations, which limit the amount of certain con-taminants in water provided by public water systems. The Food and Drug Administration (FDA) regulations estab-lish limits for contaminants in bottled water, which must provide the same protection for public health.
Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some con-taminants. The presence of contaminants does not neces-sarily indicate the water poses a health risk. More informa-tion about contaminants and potential health effects can be obtained by calling the Safe Drinking Water Hotline at 1-800-426-4791.
