A study by the Lake George Waterkeeper shows approximately one-third of septic systems that it checked within 500 feet of the Adirondack lake were near or older than their life expectancy and the ages of another one-third were unknown.
The state-funded study for the Town of Lake George also shows that the last pump-out date of more than half of the systems — on 224 of 399 properties — couldn’t be determined.
Waterkeeper Chris Navitsky presented the updated results to the Town Board on Dec. 9.
The study was based on surveys sent to residents — with about 34 percent responding _ and available municipal inventory and maintenance records.
According to the report, management programs for onsite wastewater treatment systems and septic systems are necessary and the town has put together an approach to support an inspection and management program.
Navitsky says the report will be completed by the end of the year and reviewed by town officials, who will submit it to the state.
In nearby Queensbury, a town law effective Jan. 1 requires seller of properties zoned waterfront residential pass a town inspection of their septic systems.
