Water Quality

2014 Water Quality Monitoring

The tables below show the results of the required monitoring for the period of January 1 to December 31, 2014. The tables list only drinking water contaminants that were detected

during 2014 or in the last round of sampling. The state requires monitoring for certain substances less than once per year because the concentrations of these substances do not

change frequently. In these cases, the most recent sample results are included, along with the year in which the sample was taken. There were no MCL violations during 2014.

Water Supply Sources

The primary source of supply is surface water from the Mosquito Creek and Hagermans Run watersheds near Williamsport. Most of the land in the watersheds is owned by the WMWA. The WMWA practices a proactive watershed protection program including management of land uses, patrolling the watershed, and continually monitoring for water quality. Adjacent public and private land owners are encouraged to use best management practices to help protect the source water quality.

The WMWA also maintains a treatment and pumping facility for nine wells at the Lycoming Creek wellfield near the West Branch of the Susquehanna River. When used, the groundwater is blended with the surface water supplies by means of a water transmission line to the water treatment plant, where it undergoes full conventional filtration and treatment.

Water Treatment

A modern water treatment plant treats the water from the watersheds and groundwater supplies. The treatment includes filtration, chemical treatment for corrosion control, fluoridation, and disinfection. This facility was designed to serve the greater Williamsport Area for years to come. The water from the groundwater supply is treated by packed tower aeration prior to treatment at the water treatment plant.

Source Water Assessment

The Pennsylvania Department of Environmental Protection (PaDEP) completed a source water assessment of the WMWA surface and groundwater water supplies in 2003. The assessment was required as part of the Pennsylvania Source Water Assessment and Protection Program and was designed to identify and prioritize potential sources of pollution that could contaminate the raw water supplies of public water systems. The PaDEP assessment found that the WMWA surface water supplies have little potential risk of significant contamination and were judged overall as well-protected. The highest ranked potential sources of contamination were listed as a nearby quarry and a highway. The WMWA wellfield is located in a more developed area and was judged to have a higher risk of potential contamination. The highest ranked potential sources of contamination were listed as nearby industrial contamination and two major highways. The possible risk is reduced because the groundwater undergoes remediation and treatment for organic contamination, and the finished water does not contain detectable levels of the organic contaminants. A copy of the 2003 Source Water Assessment Summary is available by writing to PaDEP, Northcentral Regional Office, 208 W. Third Street, Suite 101, Williamsport, PA 17701- 6448 or for more information visit the PaDEP website at (keyword “source water”).

Source Water Protection Plan

The WMWA has developed a Source Water Protection Plan in a proactive effort to help protect the WMWA raw water sources. Through the plan, the WMWA partners with PaDEP, state agencies, local municipal officials, Lycoming County, colleges, watershed associations, and landowners to promote awareness of water quality and quantity issues which may impact the WMWA surface and ground water sources. The WMWA also participates in the North Central Source Water Protection Alliance to coordinate regional efforts to protect public water supplies and conduct monitoring of source waters. In partnership with the U.S. Geological Survey (USGS), a baseline water quality assessment of surface water and groundwater in the Lycoming Creek watershed was conducted and monitoring of the source waters is ongoing.

Unregulated Contaminant Monitoring Regulation

Unregulated contaminants are those for which EPA has not established drinking water standards. The purpose of unregulated contaminant monitoring is to assist EPA in determining the occurrence of unregulated contaminants in drinking water and whether future regulation is warranted. In 2014, the WMWA was required to monitor for the 21 contaminants on the EPA Unregulated Contaminant (UCMR 3) Monitoring List 1 and the detects found are included in the above table. The WMWA is also required to monitor for the same list of contaminants during the first three quarters of 2015.

Contamination Potential

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 activity. Contaminants that may be present in source water include:

Microbial contaminants, such as viruses and bacteria, which may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife.

Inorganic contaminants, such as salts and metals, which can be naturally occurring or may result from urban stormwater runoff, industrial or domestic wastewater discharges, oil and gas production, mining, or farming.

Pesticides and herbicides, which may come from a variety of sources such as agriculture, urban stormwater runoff, and residential uses.

Organic chemical contaminants, including synthetic and volatile organic chemicals, which are byproducts of industrial processes and petroleum production, and can also come from gas stations, urban storm runoff, and septic systems.

Radioactive contaminants, which can be naturally-occurring or be the result of oil and gas production and mining activities.

In order to ensure that tap water is safe to drink, the U.S. EPA prescribes regulations which limit the amount of certain contaminates in water provided by public water systems. U.S. Food and Drug Administration regulations establish 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 contaminants. 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 EPA Safe Drinking Water Hotline at (800) 426-4791.

Partnership for Safe Water

The Partnership for Safe Water is a voluntary effort of drinking water organizations including the U.S. EPA, PaDEP, American Water Works Association, and water utilities throughout the country, with the goal to optimize drinking water treatment. Every year since the completion of the rigorous Phase III Self-Assessment in 2008, the WMWA has been awarded the Directors Award for meeting the water quality goals established by the Partnership program. In 2014, the WMWA was one of only 14 utilities in the country to receive the “Presidents Award” for achieving the highest possible level of individual filter turbidity performance.

Drinking Water Standards and Quality Assurance

Under federal and state laws and regulations including the Safe Drinking Water Act (SDWA), lists of contaminants and their allowable levels in drinking water supplies have been developed along with treatments that water systems must use to remove these substances. These limits are very stringent and are designed to protect the public from known adverse health effects. Samples are collected and tested to monitor the treatment processes, and to monitor water characteristics throughout the distribution system. The WMWA operates an in-house PaDEP accredited laboratory for tests which are conducted frequently. Laboratory and field technicians collect and analyze samples in accordance with quality assurance and quality control requirements. Tests which are conducted less frequently are analyzed by commercial accredited laboratories. This report conforms to the SDWA requirement that water suppliers provide detailed water quality information to their customers including regulated contaminants detected in the water. The WMWA is proud to report that the water supplied meets all established water quality standards.
