Featured Letter: Cleaning up our water is a complex problem

We can agree that nitrates in our surface water are a problem and may be the cause of the brown tide and red tide in the bay. Politicians and environmental groups have proposed that the removal of nitrates from our sanitary systems will mitigate this problem, and are forming a Wastewater Commission, comprising appointed political members to force the removal of all existing sanitary systems within 1,000 feet of the surface waters.

That may sound simple, but on close analysis it is problematic. The removal of existing sanitary systems, especially for older homes, requires excavating and removing nearby trees, and possibly destroying driveways, patios or lawns. After the installation of the new, experimental system, you still will face the task of replanting trees, reseeding lawns and the possible reconstruction of patios and driveways. There would be about 80,000 homes affected, whose owners would need to spend up to $20,000 per home to comply with these new laws. That is a cost of $1.6 billion.

Most of those homes are on the East End’s twin forks.

The problem with this mandate is that the removal of nitrates from individual sanitary systems is a very complex scientific and engineering problem and, at the present time, there is no proven way to remove nitrates from individual sanitary systems. There are some experimental systems, but they have not demonstrated effectiveness over the long term. You do not want to spend that kind of money and destroy all those yards without a proven, long-term solution.

What is needed is a committee of scientists and engineers to resolve the technical and engineering problems first before a law is put into effect.

Solve the technical problems first, then form a commission to implement the effective solution.
