Notes:
NS - No Standard
P - Principle Organic Contaminant
[1] - cis isomer = 70 ug/l, trans isomer = 100 ug/l.
[2] - Based on USEPA 1996 Drinking Water Regulations.
[3] - Based on NYSDOH MCLs-January 1992. Current MCLs, based on the last revision of the Safe Drinking Water Act
[4] - USEPA Drinking Water Standards as per CFR 40 part 141.16 are listed for strontium-90, tritium, and gross beta. MCL for both beta particle and photon radioactivity, i.e., from human made radionuclides in drinking water is the average annual concentration that shall not produce an annual dose equivalent to the total body or any internal organ greater than 4 millirem/year (40 CFR 141.16a).
