    Recreational water quality has been monitored in the Hunter region since 1996 by Hunter Water Corporation as a requirement of Environment Protection Licences, and by Port Stephens Council and Lake Macquarie City Council under the Office of Environment and Heritage’s Beachwatch Partnership Program. This report summarises the performance of 38 swimming sites in the Hunter region of New South Wales, providing a long-term assessment of how suitable a site is for swimming. Monitored sites include ocean beaches, estuarine areas in Port Stephens and designated swimming sites in Lake Macquarie.

    In 2017–2018, 84% of swimming sites in the Hunter region were graded as Good or Very Good. These sites were suitable for swimming for most or almost all of the time. This is a good result, and is an improvement in performance from the previous year. The Hunter region has a large proportion of lake/lagoon and estuarine swimming locations in its program, which have been most susceptible to impacts from wet weather conditions.

    Hunter region summary


    Beach monitoring in NSW

    The water quality of beaches and other swimming locations is monitored under the NSW Government’s Beachwatch programs to provide the community with accurate information on the cleanliness of the water and to enable individuals to make informed decisions about where and when to swim. Routine assessment also measures the impact of pollution sources, enables the effectiveness of stormwater and wastewater management practices to be assessed and highlights areas where further work is needed.

    Swimming sites in New South Wales are graded as Very Good, Good, Fair, Poor or Very Poor in accordance with the National Health and Medical Research Council’s 2008 Guidelines for Managing Risks in Recreational Waters. These Beach Suitability Grades provide a long-term assessment of how suitable a beach is for swimming. The grades are determined from the most recent 100 water quality results (two to four years’ worth of data depending on the sampling frequency) and a risk assessment of potential pollution sources.

    Recreational water quality has been monitored in the Hunter region by Hunter Water Corporation since 1996, Port Stephens Council since 2004 and Lake Macquarie City Council since 2010.

    A quality assurance program ensures that the information collected and reported by Beachwatch and its partners is accurate and reliable.

    Rainfall impacts

    Rainfall is the major driver of pollution to recreational waters, generating stormwater runoff and triggering discharges from the wastewater treatment and transport systems. Changes in rainfall patterns are reflected in beach water quality over time due to variation in the frequency and extent of stormwater and wastewater inputs.

    The Beach Suitability Grades for 2017–2018 are based on water quality data collected over the last two to four years. Rainfall over this period has been diverse, beginning in 2014 with a very wet year for the coast, followed by variable

    See the section on Quality assurance in the Statewide Summary for results of the quality assurance program.

    During 2017–2018, 38 swimming sites were monitored including ocean beaches, estuarine areas in Port Stephens and designated swimming sites in Lake Macquarie.

    rainfall with significant storm events, then extended dry periods with isolated heavy rainfall:

    • 2014–2015: wet summer with above average rainfall, particularly on the coast

    • 2015–2016: wet summer, with well above average rainfall during January, including significant storm events causing heavy rain and flooding in coastal areas

    • 2016–2017: the wettest March on record for many coastal areas and intense storm activity over summer

    • 2017–2018: prolonged dry weather periods broken by heavy rainfall at times.

    Heavy rain fell on the Hunter coast during the first half of June 2017. Monthly rainfall totals were well-above the long- term average with Nelson Bay receiving 315mm, Nobbys Beach (Newcastle) 177mm and Swansea 210mm of rainfall for the month. Dry weather followed with mostly average to below-average rainfall experienced from July 2017 to April 2018.

    A prolonged dry period was experienced during July 2017 to September 2017 with monthly rainfall well below the long- term average. Nelson Bay had its lowest July rainfall since 1995.

    Several wet weather events occurred during the warmer months, notably in February and March 2018. Very heavy rain fell in late March 2018 with Nelson Bay and Nobbys Beach (Newcastle) recording daily rainfall totals of 86mm and 74mm respectively.

    Health risks

    Contamination of recreational waters with faecal material from animal and human sources can pose significant health problems to beach users owing to the presence of pathogens (disease-causing micro- organisms) in the faecal mat
