This varies from country to country and possibly even states in US. However in general, drinking water must have NO coliform at all - that is called '0/100ml'
Swimming pool water is generally allowed '200/100ml'. Anything other than that is 'high' . In general terms coliform is in almost every pool of water and in almost every well. What we are most concerned about is E coli , which is fecal coliform and is dangerous to humans.
If you are in any doubt re E coli in drinking water, then take a sample in a sterilised bottle to your local lab. A lab test is usually about $25 in US/Canada and is well worth it to avoid dysentery and associated illnesses.

What is the acceptable water quality level for coliform?
The acceptable water quality level for coliform bacteria in drinking water is zero colony-forming units (CFU) per 100 milliliters as specified by the US Environmental Protection Agency (EPA). The presence of coliform bacteria indicates possible contamination from fecal matter and poses a health risk. Drinking water should be regularly tested to ensure it meets this standard.
What are safe levels of total coliform?
Safe levels of total coliform in drinking water are zero colony-forming units (CFU) per 100 milliliters. Any detectable presence of total coliform may indicate potential fecal contamination and further testing is needed to confirm the safety of the water for consumption.
What is the coliform cell limit in water by USPH standards?
It is 100 coliform cells for 100 ml water.
What is a coliform count of water?
Coliforms are rod shaped gram negative bacteria that are often in well water. Not all coliform are harmful, but those of fecal origin are very harmful. The lab coliform count determines what type and how many coliform are in a water sample. This result is always marked "fit for human use" or "NOT fit for human use".
What is are the safe total coliform levels?
The safe total coliform levels in drinking water should be zero, as the presence of coliform bacteria indicates potential contamination by pathogens. The U.S. Environmental Protection Agency (EPA) has set a maximum contaminant level goal (MCLG) of zero for total coliforms in drinking water. Regular testing and monitoring are essential to ensure water safety and public health. If coliforms are detected, further testing is required to identify the source and determine the appropriate response.
Coliform in well water?
Coliform in well water is the presence of fecal matter in the well water. If the bacteria is found in drinking water, appropriate action needs to be taken.

What is a coliform count?
A coliform count is a microbiological assay of the number of coliform-type bacteria living in a certain sample. This is often used as a measure of fecal contamination of water supplies.
What are the five water quality indicators?
Fertilizers, pH levels, dissolved oxygen, turbidity, and fecal coliform (for those of you who do not know what that is, it's bacteria found in poo.)
Will coliform in water hurt tomato plants and get into the fruit?
No.
Can UV kill coliform?
Yes, UV light can effectively kill coliform bacteria by damaging their DNA and preventing them from reproducing. This method is commonly used for water treatment to disinfect and purify water supplies. UV treatment can be an efficient way to eliminate coliform bacteria from water sources.
What are acceptable levels of silica in water?
The acceptable level of silica in drinking water is typically around 10 mg/L, as per EPA regulations. Silica levels below this threshold are considered safe for consumption. Excessive silica in water can lead to scaling in pipes and equipment.
