# Information Sheet



# Remote Water Quality

Moni toring Network

Network Overview



# – In 2010, the Susquehanna River Basin Commission (SRBC) initiated a network

desi gned to remotely monitor water quality conditions to maintain and protect surface waters in select portions of

the Susquehanna basin. The monitoring network uses state-of-the-art monitoring and communication technology

to collect and transmit real-time water quality data. Increasing demands for water throughout the basin, coupled

with increasing wastewater flows, require the application of this advanced technology to effectively monitor rapid

changes in water quality conditions. SRBC previously operated and maintained such a system only on the

mainstem of the Susquehanna River for the purpose of monitoring drinking water sources; however, expanding

the existing system meets a greater need to track water quality conditions within smaller rivers and streams

throughout the portion of the basin experiencing natural gas development.



# Network Implementation



# – The network consists of fifty (50)

moni toring stations in the

Pennsylvania and New York portions

of the Susquehanna basin. The

stations continuously monitor and

record the following five parameters:

temperature, pH, conductance,

dissolved oxygen, and turbidity. In

addition, water depths are recorded to

establish a relationship with stream

flows at select stations. These data

will enable water resource agencies,

water users, and the public to make

informed decisions regarding

management and use of the resource.

Eac h monitoring station includes a datasonde and data platform, powered by a solar panel or other power source.

Observations may be made as frequently as five-minute intervals, with transmission to a web site at

predetermined intervals. The web site interface also provides user-friendly access to other critical information

and tools, such as tables, graphs, maps, and statistics.

The network implementation process included SRBC staff:

• 

# Determining optimal locations for monitoring stations and obtaining

acce ss approval;

• 

# Installing and maintaining 50 monitoring stations;

• 

# Establishing a data management system for the monitoring network; and

• 

# Providing a framework for data sharing among partners. Internet-accessible data provided by the monitoring network 10/2011



# Water quality datasonde

# Ne twork Coverage

– The network area mostly spans the northern portion of the Susquehanna basin, with

a dditional focus along the Pennsylvania–New York border.

The network provides enhanced capability for maintaining and protecting the quality and reliability of water

re sources in the basin, and fosters communication and data sharing among partners. These goals represent those

supported by SRBC’s Comprehensive Plan, with respect to the Priority Management Areas related to water

quality, water supply, ecosystems, and coordination. A contribution from East Resources Inc. provided the initial

funding for the project. In 2010, the New York State Energy Research and Development Authority provided

additional funding for the expansion of the network into the New York portion of the basin. In 2011, the

Pennsylvania Department of Conservation and Natural Resources provided funding to expand the network into

state forest lands. SRBC is covering the ongoing maintenance costs for the entire network.



# Operation and Maintenance

– SRBC staff visit each station at approximately six- to eight-week intervals

to perform routine maintenance. At certain times, some stations require additional visits depending on sitespecific conditions. During any such site visits, staff collects additional data to assist with characterizing water

quality conditions (i.e., streamflow measurements, water samples for more extensive lab analyses). The aquatic

life community at each station location is also assessed once a year.
