Record how each of the following could affect the water flowing into the Waitākere dam:Walking tracksCampsite and golf clubRoadHouses

Walking Tracks: The creation of walking tracks can lead to soil erosion, especially if they are heavily used or poorly maintained. This can cause increased sediment in the water flowing into the dam, which can affect water quality. Additionally, any litter left by walkers can also end up in the water.

Campsite and Golf Club: These recreational areas can also impact the water quality. Litter, human waste, and food scraps from campsites can contaminate the water. Golf clubs often use fertilizers and pesticides on their greens, which can run off into the water supply during rain.

Road: Roads can have a significant impact on water quality. Oil, petrol, and other chemicals can leak from vehicles and end up in the water supply. Additionally, roads often have drainage systems that can direct polluted stormwater into the dam.

Houses: Residential areas can contribute to water pollution in several ways. Household chemicals, such as cleaning products, can end up in the water supply. Gardens can contribute pesticides and fertilizers. Additionally, pet waste can also end up in the water.
