Hiiiiii machiiii ✋..
➡️ Many substances that are hazardous to human health can enter water supplies.
➡️ Chemical waste from factories is sometimes dumped into rivers and lakes, or directly into the ground.
➡️ Pesticides (chemicals that kill insects) applied to farmland enter surface water and groundwater, often in large quantities.
➡️ Human sewage or cattle excrement that is untreated also causes water pollution in the same way as fertilisers do.
➡️ Human sewage also contains germs that cause diseases such as hepatitis and cholera.
➡️ The natural chemicals can cause a pollution problem similar to that caused by fertilisers.
Hope it help you!!!!!
