If I were in your situation my first step would be to ask The Villages management what action they proposed to take to reassure me that the water in my pool was safe for human contact.
I would also want to know the source of the water used to irrigate the golf course; is it from retention ponds, or is it semi-processed "grey water?"
Before considering using the pool I would give it a chlorine shock treatment followed by testing for residual chlorine and total chlorine. More about this in a moment.
The reason for the shock treatment is that chlorine will kill the bacteria which might be in the pool. Chlorine is the chemical of choice for processing drinking water throughout our nation.
When the Southern Baptist Disaster Relief volunteers go to the sites of hurricanes, floods, or other places where the safety of the water is in question, they set up their own water filtration systems. They systems are basically physical filters for the larger material that can be filtered out with a final treatment of chlorine. I have seen this done, but have not actually taken the training.
I have extracted the following from the Oklahoma Baptist Water Purification Manual: Chlorine has been universally accepted as an excellent disinfectant by public utility authorities. Chlorine kills rather than removes bacteria.
The chlorine burns the bacteria and requires a contact time to accomplish this process. Recommended chlorine injection into drinking water will range between 4 and 8 ppm, (U.S. public utility water usually has 1 to 2 ppm). Water that has been chlorinated should be allowed to sit for at least 30 minutes before being used for drinking.
The portable system uses other elements in addition to the physical filter and chlorine, but they are major elements. You can read the entire manual at

Chlorine is a powerful chemical. The Centers for Disease Control says that chlorine in a swimming pool kills the HIV virus.
I mention all of this just to give you a measure of reassurance that perhaps your pool filtration system has kept you safe in the past. As Gracie pointed out, if no one has become ill, that might be an indication that the contamination has been handled.
Regarding the testing after chlorination, this is from the Manual: Chlorine has been universally accepted as an excellent disinfectant by public utility authorities. Chlorine kills rather than removes bacteria. The chlorine burns the bacteria and requires a contact time to accomplish this process. The remaining chlorine after “burning” bacteria is called
“free chlorine”. When testing the output of the water purification unit,
the free chlorine and total chlorine should be the same, indicating no bacteria in the water. Commercially available water quality test strips (litmus strips) are provided from swimming pool supply stores. Follow the instructions on the bottle of test strips. Test strips should be kept in their original container, which should be kept closed before and after use.
I will be interested in what assurances The Villages offers.
