LAWRENCE TAP WATER PASSES CRYPTO TEST

Recently completed tests of Lawrence's water supply confirm what officials suspected all along:

City tap water does not contain any Cryptosporidia, and therefore customers are still safe drinking the water, said Roger Coffey, utilities director.

"We are very happy with the results," he said.

Responding to public concerns, the utilities department last month sent samples of the city's source- and finished-water supplies to a Vermont lab to search for signs of a single-celled parasite known as Cryptosporidium parvum.

In 1993, a Cryptosporidium outbreak in the Milwaukee public water supply killed 100 people and made more than 403,000 sick.

Although Lawrence never has received word of anyone becoming sick with cryptosporidiosis because of Lawrence tap water, officials sought a reliable lab to test for the elusive parasite. Several treatments and filtration techniques currently in place already screen for a vast majority of the particles found in raw water.

Coffey received the lab's report Monday, which reported finding no Cryptosporidium cysts, living or dead, in samples taken before and after treatment by the city's two water plants. The plants treat water from Clinton Lake and the Kansas River.
