[sunset on the dock]

Can anyone give me some info as to what is wrong? We live on the lake but have a drilled well for our water supply. If I remember correctly they had to go fairly deep. Last night the water started looking bubbly. I followed some advice from the internet which described filling a clear glass with water and if it clears from bottom to top it is indeed a bubble problem, possibly caused by a low water table. Well the water stayed cloudy...it did not clear at all. What do you all think might be the problem? Thank you.
