Cleaning and Maintenance
Trying
to keep slipways clear of weed and algal growth can be a constant
headache and very often we rely on chemicals to clear the slippery
carpet and prevent it from growing back. However the chemicals in
these products end up in the water and many are toxic to aquatic
life.
Another
way that cleaning chemicals can enter the water is through outlet
pipes- when grey water from showers and sinks does not
flow into mains sewerage but is deposited straight into the
watercourse. Any chemicals used for cleaning such as washing up
liquids, shower gels, shampoos and other detergents can have very
damaging effects on biodiversity. Phosphates found in detergents
can lead to nutrient enrichment and algal blooms which can cause
oxygen depletion and may result in suffocation of aquatic life.
Degreasers can dry the natural oils that fish need for their gills
to take in oxygen, whilst the chemicals found in some cleaning
products can disrupt the reproductive cycle of fish.
If your
business has a septic tank then you will be aware of the importance
of keeping the biological balance intact. A well maintained septic
tank has a mix of so called ‘good’ and ‘bad’ bacteria with the good
outnumbering the bad. The tank finds its own natural balance which
neutralises odours and breaks down solids. However the chemicals
used for cleaning and washing that disappear down the plug hole can
affect this natural balance causing the tank to smell and the
delicate ecosystem to break down.
