Water Quality

Since the Authority operates its own distribution system, as well as being a part owner of the Forest Park Water facilities, sampling under the SDWA (Safe Drinking Water Act) is conducted independently by both utilities in accordance with appropriate requirements. This ensures that the Authority takes all distribution samples for which it is responsible and Forest Park Water takes all samples related to a surface water treatment facility. To some extent, this arrangement results in duplication of testing, but ensures an added measure of quality control.

Following is a complete listing of all contaminants monitored for by the Authority and Forest Park Water during the 2007 calendar year.

Data presented in the above table is from the most recent testing performed in accordance with the regulations of the Pennsylvania Department of Environmental Protection. Unless otherwise noted, IOC monitoring was performed 3/06. Nitrate testing was performed quarterly.

Likely Source of Contamination: Barium: Discharge of drilling wastes, discharge from metal foundries, erosion of natural deposits; Chromium: Discharge from steel and pulp mills, erosion of natural deposits; Copper: Corrosion of household plumbing systems, erosion of natural deposits, leaching from wood preservatives; Lead: Corrosion of household plumbing, erosion of natural deposits; Nickel: Byproduct of various industrial processes, erosion of natural deposits; Nitrate (as Nitrogen): Runoff from fertilizer use, leaching from septic tanks, erosion of natural deposits.

*Naturally occurring levels of lead and copper in the source water are non-detectable. This table represents the level detected in the 90th percentile of homes monitored in accordance with the US-EPA Lead and Copper Rule. None of the homes monitored for these contaminants exceeded the Action Level.

Data presented in the above table is from calendar year 2007 monitoring performed in accordance with the regulations of the Pennsylvania Department of Environmental Protection. Coliform bacteria, disinfection residual and turbidity are monitored on a continuous basis and reported monthly. All samples collected exceeded the required Total Organic Carbon removal of 25-45%. Raw water monitoring for Giardia and Cryptosporidium was performed monthly throughout 2007. Giardia was detected in 8 out of 12 samples and Cryptosporidium was detected in 2 out of 12 samples.

Likely Source of Contamination: Turbidity: Soil runoff; Total Organic Carbon: Naturally present in the environment.
