Peoples Drug Stores yesterday reported profits increased 14 percent to $1.75 million (44 cents a share) from $1.54 million (40 cents) for the three months ended July 4.

Peoples' sales for the third quarter were up 10 percent to $143.8 million from $131.1 million.

For the first nine months of the year, Peoples earned $6.85 million ($1.77) on sales of $491.1 million, compared with $5.98 million ($1.60) on sales of $428.1 million in the same period a year ago.

Wapora Inc., a Chevy Chase environmental and energy consulting firm, reported its profits fell to $204,000 (34 cents a share) from $232,000 (39 cents) last year, despite a 16 percent increase in revenues to $7.75 million from $6.66 million.

President J.I. Bregman blamed the downturn on the state of the economy and a freeze on contracts by the Environmental Protection Agency.

Arundel Corp. of Baltimore posted a loss of $575,000 (32 cents a share) for the three months ended June 30, including a $2.1 million write-off for discontinued construction operations, down from earnings of $307,000 (17 cents) in the same period a year ago.

Arundel said its continuing operations showed a $1.5 million profit for the quarter -- up from $81,000 last year -- but the improvement did not make up for loss from termination of four joint-venture construction projects and anticipated losses on two other construction jobs.

For the first six months of the year, Arundel posted a $234,000 loss from continuing operations and a $2.2 million write-off for its discontinued businesses for a net loss of $2.47 million ($1.41.)
