  • Bear River

    Nitrate levels in the Bear River are very low for PEI and are close to levels that are

    considered pristine. Measured concentrations were in the range of 0.1 -0.5 mg/l in the last

    15 samples. After a short period of decline (2012-2013) nitrate concentrations in Bear

    River increased slightly in 2014 and 2015. Current concentrations are still lower than

    those observed between 2004 and 2011 however. This site is located in St. Margaret’s

    just upstream of the culvert on the Bear River Road near Rt. 16.

    List of Steams

  • Cain’s Brook

    Nitrate levels in Cain’s Brook are currently in the range of 0.4 – 2.7 mg/l (last 15

    samples). Nitrate in Cain’s Brook had a lengthy period of increasing concentrations.

    Nitrate concentrations have declined slightly since 2012, but seem to be levelling off or

    perhaps even increasing very slightly as of 2015. Current levels are still slightly lower

    than they were between 2008 and 2012 however. This station is located at the Rt. 2

    stream crossing in Bloomfield.

    List of Streams

  • Clyde River

    Nitrate levels in the Clyde River are currently in the range of 1.8 – 3.3 mg/l (last 15

    samples). Nitrate levels in the Clyde River have declined slightly from the highest

    recorded levels in 2004. This decline is continuing in 2015. This site is located

    downstream of the Bannockburn Road in Clyde River.

    List of Streams

  • Dunk River

    Nitrate levels in the Dunk River are currently in the range of 2.9 – 5.9 mg/l (last 15

    samples). There is a short gap in the data as the Dunk River was not sampled between

    1974 and 1979. The highest nitrate levels in the Dunk River were recorded in 2009 and

    have declined slightly since then. This decline continued in 2015. This site is located at

    the Wall Road stream crossing.

    List of Streams

  • Mill River

    Nitrate levels in the Mill River are currently in the range of 0.6 to 3.8 mg/l (last 15

    samples). Nitrate levels in the Mill River decreased in 2010 and 2012, but have begun

    increasing again after 2012, although this rate of increase may have slowed in 2015.

    Current nitrate levels in Mill River are still below the highest concentrations recorded (in

    2007). This station is located just upstream of Bloomfield Park.

    List of Streams

  • Montague River

    Nitrate levels in the Montague River are currently in the range of 0.4 – 2.7 mg/l (last 15

    samples). Nitrate levels in the Montague River have declined slightly since the highest

    levels were recorded in 2004. Nitrate levels at this site have remained fairly constant

    since 2012. This site is located just upstream of Knox’s Pond.

    List of Streams

  • Morell River

    Nitrate levels in the Morell River are relatively low for PEI. Nitrate levels in the Morell

    River are currently between 0.1 and 0.5 mg/l (last 15 samples). Nitrate levels in the

    Morell River were at their maximum in 2004, but have declined overall since that time.

    The latest data for 2015 appears to show a slight increase over the concentrations of the

    previous few years. There is a gap in the data as the Morell River was not sampled

    between 1995 and 2000. The site is located at Indian Bridge.

    List of Streams

  • Valleyfield River

    Nitrate levels in the Valleyfield River are currently between 0.3 - 1.5 mg\l (last 15

    samples). Nitrate levels in the Valleyfield River were at their maximum in 2004 and have

    decreased slightly, but steadily, since that time. The most recent results, for 2015, may

    show that the rate of this decline is slowing or that levels may be starting to increase once

    again. The site is located in Kilmuir at the stream crossing on the Loane Rd.

    List of Streams

  • West River

    Nitrate levels in the West River are currently between 0.9 and 1.5 mg/l (last 15 samples).

    Nitrate levels in the West River have decreased slightly but steadily since their peak in

    2004. The latest results from 2015 seem to show that concentrations are levelling off or

    are slightly increasing. This site is located in Riverdale at the stream crossing on the

    Bolger Park Road.

    List of Streams

  • Wilmot River

    Nitrate levels in the Wilmot River are high for PEI and are currently between 4.9 and 6.5

    mg/l (last 15 samples). Nitrate levels in the Wilmot River have decreased slightly since

    their maximum recorded levels in 2010. The latest results from 2015 show that nitrates in

    the Wilmot River are either levelling off or beginning to increase slightly once again.

    This site is located at the stream crossing on the Cairns Road.
