Answer:
1.There are two main sources of water: surface water and groundwater. Surface Water is found in lakes, rivers, and reservoirs. Groundwater lies under the surface of the land, where it travels through and fills openings in the rocks. The rocks that store and transmit groundwater are called aquifers
2.Seawater is considered to be very hard due to various dissolved salts. Typically seawater's hardness is in the area of 6,630 ppm (6.63 grams per litre). In contrast, freshwater has hardness in the range of 15 to 375 ppm
3.Most of the time, U.S. groundwater is safe to use. However, groundwater sources can become contaminated with germs, such as bacteria, viruses, and parasites, and chemicals, such as those used in fertilizers and pesticides. Contaminated groundwater can make people sick. Water infrastructure requires regular maintenance.
