Thank you, Mark. Yes, thank you, Mark. Our total revenue from continuing operations for the third quarter was $30.2 million compared to prior year of $22.5 million. That's an increase of 33.9%. This $7.7 million increase was the result of a $10 million increase in our projects revenue by the Service Segment or 85.5%. Our continued revenue growth from our projects on the West Coast was the primary driver of this increase. Offsetting this increase was lower revenue from our Treatment Segment, which compared to prior year -- when compared to prior year as the COVID pandemic continues to impact waste receipts in the quarter, with customer sites slow to resume shipments of waste.
For 9 months ended September 30, revenue was $77.1 million compared to $51.4 million in prior year. That's an increase of $25.7 million or 50% growth over prior year. Our cost of sales in the quarter was $25.4 million compared to $17.4 million in the prior year or an increase of $8 million. Increased revenue from our Service Segment was the main driver of this increase, accounting for $8.4 million of the increase in direct costs as costs such as labor, subcontractors and travel were up while fixed costs increased an additional $405,000. These increases were offset partially by a drop in our cost of sales in the Treatment Segment as lower revenue resulted in a reduction of $1.2 million in costs, mostly variable, made up of transportation and disposal; while our fixed facility costs increased $436,000 related to maintenance, regulatory and other depreciation type expenses.
Our gross profit for the quarter was $4.8 million or 15.7% of revenue compared to the prior year third quarter gross profit, which was $5.2 million or 22.9% of revenue. Gross profit in our Service Segment increased approximately $1.8 million, but was offset by a drop in the Treatment Segment of $2.2 million. The margin decrease was primarily impacted by the drop in Treatment revenue, though we did see improved waste mix, which partially offset this impact. Increased revenue in the Service Segment was -- as well as marginal improvement in the profitability of the projects positively offset the drop on the Treatment side. For 9 months ended September 30, our gross profit is at $12.7 million or 16.5% compared to $10.9 million or 21.3% in the prior year.
Our G&A costs for the quarter were $3.3 million compared to $2.9 million in the prior year. We saw higher wages, incentives and bid and proposal consulting type expenses. And they were slightly offset by lower travel and bad debt. Our 9 months -- for 9 months ended September 30, our current SG&A expenses were $8.9 million or 11.6% of revenue compared to $8.5 million in the prior year, which was 16.6% of revenue. Our income from continuing operations net of taxes for the quarter was $1.5 million compared to $1.9 million in the prior year. Year-to-date, our income from continuing operations net of taxes is $3 million compared to prior year when it was $1.7 million.
We had net income attributable to common shareholders of $1.4 million compared to last year's income of $1.8 million. That's for the quarter. Year-to-date, net income attributable to common shareholders is $2.9 million compared to income of $1.4 million in the prior year. Our basic net income per share for the quarter is $0.12, which was down from prior year's $0.15 per share. But our basic net income per share year-to-date is at $0.24 compared to $0.12 in the prior year. Our adjusted EBITDA from continuing operations, as we defined it in our -- in this morning's press release, is $2 million compared to $2.4 million in the prior year. While year-to-date, our adjusted EBITDA is $4.7 million compared to $3.5 million year-to-date in the prior year.
Turning to our balance sheet as it compares to 12/31/19. Our cash balance at the end of the third quarter was $4.8 million, which was up from the $390,000 at year-end. This is due to the PPP loan that we received in April. Our accounts receivable and unbilled receivables cumulatively were up approximately $6.6 million, reflecting increased unbilled revenue in the Service Segment at the end of the quarter, which is -- and much of this is usually built immediately at the new quarter. Our current liabilities were up $4.9 million, reflecting increased accounts payable and expenses related to the increase in Service Segment business. The increase in our long-term liabilities of $5 million is primarily due to the PPP loan we received in April. Our backlog of waste at the end of the quarter was approximately $7.5 million, which is down from $8.5 million at year-end and down from $10.6 million at the end of the third quarter in 2019. Our services backlog at September 30 was approximately $38 million.
And our total debt, excluding debt issuance and debt discount costs, at the end of the quarter was approximately $8.8 million, with $1.6 million owed to our primary lender, PNC Bank; $5.3 million due to PNC Bank for the PPP loan received in April; $523,000 owed on our private shareholder loan; and $1.4 million for other capital leases and loans. Finally, I'll summarize our cash flow activity for the first 9 months of 2020. Our cash provided by continuing operations was $3.5 million. Our cash used by discontinued operations was $329,000. Cash used for investing in continuing operations was $1.5 million. Cash provided by investing activities on discontinued operations was $118,000. Cash provided by financing was $2.7 million, and this is broken down as the receipt of the PPP loan of $5.3 million, offset by our monthly payments of our -- on our term loan of $320,000, our net payments to the revolver of $321,000, payments to the shareholder loan of $1.5 million and other lease financing payments of $414,000.
With that, I'll now turn the call over to questions.
