The water frame, developed by Richard Arkwright in the late 18th century, contributed to the industrial revolution but also had several negative effects. It led to the exploitation of labor, particularly child labor, as workers were drawn to factories for low wages and long hours in often dangerous conditions. Additionally, the concentration of production in factories increased urbanization, resulting in overcrowded cities with poor living conditions. The environmental impact also grew, as water sources were often polluted and natural landscapes altered to accommodate industrial needs.

To determine if a sample of water is pure or polluted, you can conduct physical, chemical, and biological tests. Physically, you can assess clarity, color, and odor. Chemically, you can test for contaminants such as heavy metals, pesticides, or excess nutrients using methods like spectrophotometry or chromatography. Biologically, analyzing for harmful microorganisms or pathogens through microbiological assays will provide insight into the water's purity.

A levee is an embankment built along rivers or flood-prone areas to control water flow and prevent flooding. By rising above the normal water level, it acts as a barrier that directs excess water away from populated areas and infrastructure. Levees can redirect water into designated channels or floodplains, helping manage and mitigate flood risks. However, if not properly maintained, they can fail, leading to potentially catastrophic flooding.

Water pollution has severe impacts on both human health and ecosystems. Contaminated water can lead to various health issues, including gastrointestinal diseases and long-term illnesses like cancer. It also disrupts aquatic habitats, harming wildlife and reducing biodiversity. Additionally, polluted water sources can affect agriculture and food supply, ultimately threatening food security and livelihoods.

Urbanization and industrialization lead to river pollution primarily through the increased runoff of contaminants from urban areas and industrial sites. As cities expand, impervious surfaces like roads and buildings prevent water absorption, causing stormwater to carry pollutants such as oils, heavy metals, and chemicals directly into nearby rivers.
