Poor health.
Brackish water in Jamestown was primarily caused by the combination of rising sea levels and excessive groundwater extraction. The colony's reliance on wells for fresh water, coupled with drought conditions, led to saltwater intrusion from the nearby Chesapeake Bay. This intrusion resulted in a mix of saltwater and freshwater, creating brackish conditions that compromised the availability of potable water for the settlers. Additionally, poor site selection for the settlement, located on a peninsula, further exacerbated the issue.
It was swamp water, either very salty or slimy and dirty
You basically said it in your question. The ground was swampy so the water was bad, there were mosquitoes, and disease.
Jamestown was a very dirty place. There were mosquitoes carrying malaria in the swamps, the water was brackish, and a major drought almost caused the settlement to disappear Williamsburg was on higher land away from disease. Also, the water was drinkable. Overall, Williamsburg was a much cleaner and nicer place to live.
Poor health.
many jamestown colonists became sick from malaria and from the drinking water
They landed during a heavy drought year and obtained their drinking water from the river, which during the drought was quite brackish, making them very ill.
The twice-daily event that causes water levels around Jamestown to rise and makes wells and fresh water streams become brackish is the tide. The tidal cycle brings in seawater, increasing the salinity of the water in wells and freshwater streams located in the vicinity of Jamestown.

There were many problems in settling in Jamestown. Food was scarce. They had a Brackish/(Unclean Not health) Water supply. Where they settled was muddy. Their were mosquitos that were spreading diseases. (Maleria) People were spending their time digging for gold instead of planting crops for food. And they didn't have many hard workers because most of the people who traveled to the Americas and founded Jamestown were Upper-Class Englishmen.
The water in Jamestown was contaminated with pathogens from human waste that caused diseases like dysentery and typhoid fever. Poor sanitation practices in the settlement contributed to the spread of these waterborne illnesses among the colonists.
The mixing of fresh water and saltwater is called brackwater or brackish water.
The composition of brackish water is determined by the balance of the freshwater inflow and saltwater intrusion; factors such as precipitation, evaporation, and tidal dynamics affect this balance. Additionally, the geography of the surrounding area, the types of sediments and rocks present, and human activities can also influence the composition of brackish water.
