  • Effective rainfall which triggers contamination events (and typical duration of contamination).

  • For discharges from sewage systems or treatment facilities, include what type of treatment is

used, the system capacity, flow rates and variability, and indicator standards.

  • For animals/birds, stocking densities and types of animals, indicator data will be necessary to

support and supplement this information.

Chemical and other hazards

Water quality

Is the water likely to be affected by: Discharges from industrial sources?

Agricultural

drainage?

Water craft mooring or use?

Urban surface runoff?

Are onshore winds likely to carry polluted water into the bathing area? Are currents likely to carry polluted water into the bathing area? ____

____

Are tides likely to affect water quality in the bathing area?

____

Sand quality

Is the sand likely to be affected by: Discharges from industrial sources?

Agricultural drainage?

Water craft mooring or use? Are plastic residues present? Urban surface runoff? _ _ _ A r e t a r r e s i d u e s p r e s e n t ? _ _ _ Are algae present? ___ Are other residues present? ___ Supporting chemical water quality data or additional comments: _______

Note: Any of the above with a “yes” answer require a detailed investigation and risk analysis. This investigation should include:

  • Proximity of potential contamination source to bathing area.

  • For boats, densities and pumpouts.

  • For urban surface runoff, the effective rainfall.

  • For discharge from industrial sites, the type of discharge, treatment being used, flow rates and

variability, system capacity and chemical/indicator standards.

Please attach a map of the beach area included in this sanitary inspection, with possible contamination sources (rivers, storm drains, outfalls, etc.) marked. If possible, maps of the entire catchment area indicating land-use, topography, and infrastructure networks (i.e. wastewater and storm drain systems, etc.) should also be attached.

Reporting systems

Are there formal mechanisms for reporting waste discharges, spills, treatment bypasses, etc. to the local health authorities? ___

Is there an illness or injury reporting mechanism in place that would be effective for
